		ENBrussels, 11.3.2011COM(2011) 120 final2011/0053 (COD)Proposal for aDIRECTIVE OF THE EUROPEAN PARLIAMENT AND OF THE COUNCILrelating to tyres for motor vehicles and their trailers and to their fitting(Codification)EXPLANATORY MEMORANDUM1. In the context of a people’s Europe, the Commission attaches great importance to simplifying and clarifying the law of the Union so as to make it clearer and more accessible to citizens, thus giving them new opportunities and the chance to make use of the specific rights it gives them.This aim cannot be achieved so long as numerous provisions that have been amended several times, often quite substantially, remain scattered, so that they must be sought partly in the original instrument and partly in later amending ones. Considerable research work, comparing many different instruments, is thus needed to identify the current rules.For this reason a codification of rules that have frequently been amended is also essential if the law is to be clear and transparent.2. On 1 April 1987 the Commission decided [1] to instruct its staff that all acts should be codified after no more than ten amendments, stressing that this is a minimum requirement and that departments should endeavour to codify at even shorter intervals the texts for which they are responsible, to ensure that their provisions are clear and readily understandable.3. The Conclusions of the Presidency of the Edinburgh European Council (December 1992) confirmed this [2], stressing the importance of codification as it offers certainty as to the law applicable to a given matter at a given time.Codification must be undertaken in full compliance with the normal procedure for the adoption of acts of the Union.Given that no changes of substance may be made to the instruments affected by codification, the European Parliament, the Council and the Commission have agreed, by an interinstitutional agreement dated 20 December 1994, that an accelerated procedure may be used for the fast-track adoption of codification instruments.4. The purpose of this proposal is to undertake a codification of Council Directive 92/23/EEC of 31 March 1992 relating to tyres for motor vehicles and their trailers and to their fitting [3]. The new Directive will supersede the various acts incorporated in it [4]; this proposal fully preserves the content of the acts being codified and hence does no more than bring them together with only such formal amendments as are required by the codification exercise itself.5. The codification proposal was drawn up on the basis of a preliminary consolidation, in 22 official languages, of Directive 92/23/EEC and the instruments amending it, carried out by the Publications Office of the European Union, by means of a data-processing system. Where the Articles have been given new numbers, the correlation between the old and the new numbers is shown in a table contained in Annex VIII to the codified Directive.92/23/EEC (adapted)2011/0053 (COD)Proposal for aDIRECTIVE OF THE EUROPEAN PARLIAMENT AND OF THE COUNCILrelating to tyres for motor vehicles and their trailers and to their fitting(Codification)(Text with EEA relevance)THE EUROPEAN PARLIAMENT AND THE COUNCIL OF THE EUROPEAN UNION,Having regard to the Treaty on the Functioning of the European Union, and in particular Article 114 thereof,Having regard to the proposal from the European Commission,After transmission of the draft legislative act to the national Parliaments,Having regard to the opinion of the European Economic and Social Committee [5],Acting in accordance with the ordinary legislative procedure,Whereas:(1) Council Directive 92/23/EEC of 31 March 1992 relating to tyres for motor vehicles and their trailers and to their fitting [6] has been substantially amended several times [7]. In the interests of clarity and rationality the said Directive should be codified.92/23/EEC recital 4 (adapted)(2) Directive 92/23/EEC is one of the separate Directives of the EC type-approval system provided for in Directive 2007/46/EC of the European Parliament and of the Council of 5 September 2007 establishing a framework for the approval of motor vehicles and their trailers, and of systems, components and separate technical units intended for such vehicles (Framework Directive) [8], and lays down technical prescriptions which motor vehicles and their trailers must satisfy relating , inter alia, to pneumatic tyres. Those technical prescriptions concern the approximation of the laws of the Member States to enable the EC type-approval procedure provided for in Directive 2007/46/EC to be applied in respect of each type of motor vehicle and trailer. Consequently the provisions laid down in Directive 2007/46/EC relating to motor vehicles and their trailers, and of systems, components and separate technical units intended for such vehicles, apply to this Directive.92/23/EEC recital 6(3) Rules on tyres should lay down common requirements concerning not only their characteristics, but also the requirements for the equipment of vehicles and their trailers with regard to their tyres.92/23/EEC recital 8 (adapted)(4) It is desirable to take into account the technical requirements adopted by the UN Economic Commission for Europe in its Regulation No 30 (‘Uniform provisions concerning the approval of pneumatic tyres for motor vehicles and their trailers’), as amended [9], in its Regulation No 54 (‘Uniform provisions concerning the approval of pneumatic tyres for commercial vehicles and their trailers’) [10], in its Regulation No 64 (‘Uniform provisions concerning the approval of vehicles equipped with temporary-use spare wheels/tyres’), as amended, [11] and in its Regulation No 117 ('Uniform Provisions Concerning the Approval Of Tyres With Regard To Rolling Sound Emissions And To Adhesion On Wet Surfaces'), as amended [12] , which are annexed to the Agreement of the United Nations Economic Commission for Europe concerning the adoption of uniform technical prescriptions for wheeled vehicles, equipment and parts which can be fitted and/or be used on wheeled vehicles and the conditions for reciprocal recognition of approvals granted on the basis of these prescriptions (Revised 1958 Agreement) [13] .(5) This Directive should be without prejudice to the obligations of the Member States relating to the time-limits for transposition into national law and application of the Directives set out in Annex VII, Part B,HAVE ADOPTED THIS DIRECTIVE:92/23/EEC (adapted)Article 1For the purposes of this Directive the following definitions shall apply :2001/43/EC Art. 1 pt. 2(a) ‘tyre’ means any new pneumatic tyre including a winter tyre with holes for studs, in the form of original equipment or of a replacement, intended to be fitted to vehicles to which Directive 2007/46/EC applies.

Member States shall grant EC type-approval to all vehicles in respect of their tyres under the conditions laid down in Annex III, where those tyres (including spare tyres, where appropriate) meet the requirements of Annex II and the requirements concerning vehicles laid down in Annex IV, and shall allocate to any such vehicle an approval number as specified in Annex III.92/23/EEC (adapted)1 2001/43/EC Art. 1 pt. 1Article 4The approval authority of a Member State shall, within one month of issuing or refusing an 1 EC type-approval for a component (tyre) or vehicle, send a copy of the relevant certificate, models of which are given in the Appendices to Annex I and Annex III, to the other Member States and, if requested, send the test report on any type of tyre approved.92/23/EEC1 2001/43/EC Art. 1 pt. 1Article 5No Member State may prohibit or restrict the placing on the market of tyres bearing the 1 EC type-approval mark.92/23/EEC (adapted)1 2001/43/EC Art. 1 pt. 1Article 6No Member State may refuse to grant 1 EC type-approval or national type-approval to a vehicle on grounds relating to its tyres if those tyres bear the 1 EC type-approval mark and are fitted in accordance with the requirements laid down in Annex IV.Article 7No Member State may prohibit the use of a vehicle on grounds relating to its tyres if those tyres bear the 1 EC type-approval mark and are fitted in accordance with the requirements laid down in Annex IV.92/23/EECArticle 81. If, on the basis of a substantiated justification, a Member State considers that a tyre type or a vehicle type is dangerous although complying with the requirements of this Directive, it may, within its territory, provisionally prohibit the marketing of that product or subject it to special conditions. It shall immediately inform the other Member States and the Commission thereof, stating the grounds for its decision.2. The Commission shall, within six weeks, consult the Member States concerned, following which it shall deliver its opinion without delay and take the appropriate steps.92/23/EEC (adapted)1 2001/43/EC Art. 1 pt. 13. If the Commission is of the opinion that technical adaptations to this Directives are necessary, such adaptations shall be adopted in accordance with the procedure laid down in Article 11. In this event, the Member State which has adopted safeguard measures may maintain them until the entry into force of the adaptations.Article 91. The Member State which has granted the 1 EC type-approval for a component (tyre) or vehicle shall take the measures required in order to verify that production models conform to the approved type in so far as this is necessary and if need be in cooperation with the approval authorities in the other Member States. For this purpose, that Member State may at any time check the conformity of the tyres or vehicles to the requirements of this Directive. Such verification shall be limited to spot checks.2. If the Member State referred to in paragraph 1 finds that a number of tyres or vehicles with the same approval marking do not conform to the approved type, it shall take the necessary measures to ensure that production models so conform. Where there is a consistent failure to conform, those measures may extend to a withdrawal of 1 EC type-approval . The authorities shall take the same measure if they are informed by the approval authorities of another Member State of such failure to conform.3. The approval authorities of the Member States shall within one month notify each other using the relevant form shown in the Appendices to Annex I and Annex III of any withdrawal of 1 EC type-approval and of the reasons for such a measure.Article 10Any decision taken pursuant to the provisions adopted in implementation of this Directive to refuse or withdraw 1 EC type-approval for a tyre or 1 for a vehicle with regard to the fitting of its tyres implying a prohibition of marketing or of use shall set out in detail the reasons on which it is based. Every such decision shall be notified to the party concerned, who shall at the same time be informed of the remedies available to him under the laws in force in the Member States and of the time limits allowed for the exercise of such remedies.Article 11Any amendments necessary to adapt the requirements of Annexes I to VI to technical progress shall be adopted in accordance with the procedure referred to in Article 40(2) of Directive 2007/46/EC.2001/43/EC Art. 1 pt 6 (adapted)Article 121.

Approval numbers assigned pursuant to Annex V must be followed by the suffix ‘s’ where ‘s’ is an abbreviation for sound.4.5. An example of the EC type-approval mark is given below:(...PICT...)The tyre bearing the EC type-approval mark shown above is a commercial vehicle tyre (00) satisfying the EC requirements (e), for which the EC type-approval mark has been granted in Ireland (24) under the number 479 pursuant to Annex II and in Italy (3) under the number 687-s pursuant to Annex V.Note: The numbers ‘479’ and ‘687’ (EC -mark type-approval numbers) and the number ‘24’ and the digit ‘3’ (letters and number of the Member States which granted the EC type approval) are for guidance only.The approval numbers must be placed close to the rectangle and may be above, below, to the left or to the right. The characters of the approval number must all be on the same side of the ‘e’ and face in the same direction.5. MODIFICATION OF A TYRE TYPE5.1. If a tyre EC type-approved pursuant to Annex II or pursuant to Annex V has been modified, the provisions of Articles 13 to 16 of Directive 2007/46/EC shall apply.5.2. If the tread pattern of a tyre has been modified in the case of type-approvals pursuant to Annex II, no repetition of the tests prescribed in Annex II is considered necessary.5.3. In the case where tyre-size designations or trade marks are added to a range of tyres type-approved pursuant to Annex V, any requirement for retesting shall be determined by the type approval authority.5.4. In the case of modification of the tyre tread pattern of a range of tyres approved pursuant to Annex V, a representative set of samples shall be retested unless the type approval authority is satisfied that the modification does not affect the tyre/road noise emissions.6. CONFORMITY OF PRODUCTION6.1. The general rules to ensure the conformity of production shall be adopted in accordance with the provisions laid down in Article 12 of Directive 2007/46/EC.6.2. In particular, when checks are carried out in accordance with Appendix 1 to Annex V in order to check the conformity of production, if the noise level of the tyre tested does not exceed the limit values set out in point 4.2. of Annex V by more than 1 dB(A), the production shall be deemed to conform to the requirements of section 4 of Annex V.2001/43/EC Art. 1 pt. 5 and Annex pt. 3 (adapted)Appendix 1INFORMATION DOCUMENT No … RELATING TO EC TYPE-APPROVAL FOR A TYPE OF TYRE92/23/EEC(...PICT...)2001/43/EC Art. 1 pt. 5 and Annex pt. 4Appendix 2EC TYPE-APPROVAL CERTIFICATE(tyres)MODEL(maximum format: A4 (210 mm × 297 mm))92/23/EEC (adapted)1 2001/43/EC Art. 1 pt. 12 2001/43/EC Art. 1 pt. 5 and Annex pt. 5Stamp of  Administration |Communication concerning the:– EC type-approval(1),– extension of EC type-approval(1),– refusal of EC type-approval(1),– withdrawal of EC type-approval(1),– discontinuation of production(1),of a component with regard to Directive […] relating to tyres.(...PICT...)1 2(...PICT...)2001/43/EC Art. 1 pt. 5 and Annex pt. 6 (adapted)Appendix 3INFORMATION DOCUMENT No…RELATING TO EC TYPE – APPROVAL FOR A TYPE OF TYRE RELATING TO TYRE/ROAD NOISE EMISSION(...PICT...)2.5.

However, for the types of tyre for which the size designation is given in the first column of the tables in Appendix 5 A or 5 B, the measuring rim width (A) and the section width (S) are those given opposite the tyre size designation in those tables.6.1.2. Outer diameter of a tyre6.1.2.1. Except as provided by point 6.1.2.2, the outer diameter of a tyre is calculated by the following formula:D = d + 0,02Hwhere: |— | D is the outer diameter expressed in mm, |— | d is the conventional number defined in point 2.17.1.3, expressed in mm, |— | H is the nominal section height in mm and is equal to S1 × 0,01 Ra; |where: |— | Ra is the nominal aspect ratio, |all as shown on the sidewall of the tyre in the tyre-size designation in conformity with the requirements of section 3.6.1.2.2. However, for the types of tyres for which the size designation is given in the first column of the tables of Appendix 5 the outer diameter is that given opposite the tyre size designation in those tables.6.1.3. Method of measuring tyre dimensionsThe actual dimensions of tyres are measured as prescribed in Appendix 6.6.1.4. Tyre section width: specification of tolerance6.1.4.1. The overall width of a tyre may be less than the section width determined pursuant to point 6.1.1 or shown in Appendix 5;6.1.4.2. It may not exceed that value by more than the following:6.1.4.2.1. diagonal (bias-ply) tyres: 6 % for passenger car tyres, 8 % for commercial vehicle tyres;6.1.4.2.2. radial-ply tyres: 4 %; and6.1.4.2.3. in addition, if the tyre has a special protective band, the figure as increased by the above tolerances may be exceeded by 8 mm.6.1.4.2.4. However, for tyres of a section width exceeding 305 mm intended for dual (twin) mounting the nominal value must not be exceeded by more than 2 % for radial-ply or 4 % for diagonal (bias-ply) tyres.6.1.5. Tyre outer diameter: specification of toleranceThe outer diameter of a tyre must not be outside the values Dmin and Dmax obtained from the following formulae:Dmin | = | d + (2H × a) |Dmax | = | d + (2H × b) |6.1.5.1. for sizes listed in Appendix 5:H = 0,5 (D — d) — (for references see point 6.1.2.2).6.1.5.2. for other sizes not listed in Appendix 5:‘H’ and ‘d’ are as defined in point 6.1.2.1.6.1.5.3. coefficients ‘a’ and ‘b’ are respectively:6.1.5.3.1. coefficient ‘a’ = 0,97;6.1.5.3.2. coefficient ‘b’ for normal, special, snow or temporary-use spare tyresCategory of use | Passenger car tyres | Commercial vehicle tyres || Radial | Bias | Radial | Bias |Normal | 1,04 | 1,08 | 1,04 | 1,07 |Special | — | — | 1,06 | 1,09 |Snow | 1,04 | 1,08 | 1,04 | 1,07 |Temporary-use | 1,04 | 1,08 | — | — |6.1.5.4. For snow tyres the outer diameter (Dmax) established in conformity with point 6.1.5 may be exceeded by 1 %.6.2. Load/speed test requirement6.2.1. The tyre must undergo a load/speed test carried out in accordance with the relevant procedure described in Appendix 7.6.2.2. A tyre which, after undergoing the relevant load/speed test, does not exhibit any tread separation, ply separation, cord separation, chunking or broken cords is deemed to have passed the test.6.2.3. The outer diameter of the tyre, measured six hours after the load/speed test, must not be more than 3,5 % greater than the outer diameter as measured before the test.6.2.4. Where application is made for the EC type- approval of a type of commercial vehicle tyre the load/speed combinations given in the table in Appendix 8 apply and, the load/speed test prescribed in point 6.2.1 need not be carried out for load and speed values other than the nominal values.6.2.5. Where application (see point 6.13 of Appendix I to Annex I) is made for the EC type-approval of a type of commercial vehicle tyre which has a load/speed combination in addition to the one that is subject to the variation of load with speed given in the table in Appendix 8, the load/speed test prescribed in point 6.2.1 must also be carried out on a second tyre of the same type at the additional load/speed combination.6.2.6. Where a tyre manufacturer produces a range of tyres it is not considered necessary to carry out a load/speed test on every type of tyre in the range. Worst-case selection may be made, at the discretion of the approval authority.6.3. Tread-wear indicators6.3.1. In the case of passenger car tyres the tread of the tyre must include not less than six transverse rows of tread-wear indicators, approximately equally spaced and situated in the wide grooves in the central zone of the tread, which covers approximately three quarters of the tread width. The tread-wear indicators must be such that they cannot be confused with the rubber ridges between the ribs or blocks of the tread.6.3.2. However, in the case of tyres of dimensions appropriate for mounting on rims of a nominal diameter of 12″ or less, four rows of tread-wear indicators are acceptable.6.3.3.

DIMENSIONS(see Annex II point 6.1.3)PART A: PASSENGER CAR TYRES1.1. The tyre is mounted on the measuring rim specified by the manufacturer pursuant to point 6.11 of Annex I, Appendix 1.1.2. The pressure in the tyre is then adjusted as follows:1.2.1. in standard bias — belted tyres to 1,7 bar;1.2.2. in diagonal (bias-ply) tyres to the pressure shown below (bar):Ply-rating | Speed category || L, M, N | P, Q, R, S | T, U, H, V |4 | 1,7 | 2,0 | — |6 | 2,1 | 2,4 | 2,6 |8 | 2,5 | 2,8 | 3,0 |1.2.3. in standard radial tyres to 1,8 bar,1.2.4. in reinforced tyres to 2,3 bar, and1.2.5. in T-type temporary-use spare tyres: to 4,2 bar.2. The tyre, mounted on its rim, is conditioned at the ambient room temperature for not less than 24 hours, with the exception referred to in point 6.2.3 of Annex II.3. The pressure is readjusted to that specified in point 1.2.4. The overall width is measured by calliper at six equally-spaced points, account being taken of the thickness of the protective ribs or bands. The highest measurement so obtained is taken as the overall width.5. The outer diameter is determined by measuring the maximum circumference and dividing the figure so obtained by π (3,1416).PART B: COMMERCIAL VEHICLE TYRES1. The tyre is mounted on the measuring rim specified by the manufacturer pursuant to point 6.11 of Appendix 1 to Annex I and is inflated to a pressure specified by the manufacturer pursuant to point 6.12 of Annex I, Appendix 1.2. The tyre fitted on its rim is conditioned to the ambient temperature of the laboratory for at least 24 hours.3. The pressure is readjusted to the value specified in section 1.4. The overall width is measured by calliper at six equally-spaced points, account being taken of the thickness of the protective ribs or bands. The highest measurement so obtained is taken as the overall width.5. The outer diameter is determined by measuring the maximum circumference and dividing the figure so obtained by π (3,1416).Appendix 7LOAD/SPEED TEST-PROCEDURE [30](see Annex II, point 6.2)PART A: PASSENGER CAR TYRES1. Preparing the tyre1.1. A new tyre is mounted on the test rim specified by the manufacturer pursuant to point 6.11 of Annex I, Appendix 1.1.2. It is inflated to the appropriate pressure as given in the table below:Test pressure (bar)Speed category | Diagonal (bias-ply) tyres | Radial tyres | Bias-belted tyres || Ply-rating | Standard | Reinforced | Standard || 4 | 6 | 8 | | | |L, M, N | 2,3 | 2,7 | 3,0 | 2,4 | — | — |P, Q, R, S | 2,6 | 3,0 | 3,3 | 2,6 | 3,0 | 2,6 |T, U, H | 2,8 | 3,2 | 3,5 | 2,8 | 3,2 | 2,8 |V | 3,0 | 3,4 | 3,7 | 3,0 | — | — |T-type temporary use spare tyres: to 4,2 bars. |1.3. The manufacturer may request, giving reasons, the use of an inflation pressure differing from those under point 1.2. In such a case the tyre is inflated to that pressure (see point 6.14 of Appendix 1 to Annex I).1.4. The tyre-and-wheel assembly is conditioned at test-room temperature for not less than three hours.1.5. The tyre pressure is readjusted to that specified in point 1.2 or 1.3.2. Carrying out the test2.1. The tyre-and-wheel assembly is mounted on a test axle and pressed against the outer face of a smooth wheel 1,70 m ± 1 % or 2 m ± 1 % in diameter.2.2. Apply to the test axle a load equal to 80 % of:2.2.1. the maximum load rating equated to the load capacity index for tyres with speed symbols L to H inclusive;2.2.2. the maximum load rating associated with a maximum speed of 240 km/h for tyres with speed symbol ‘V’ (see point 2.31.2 of Annex II).2.3. Throughout the test the tyre pressure must not be corrected and the test load must be kept constant.2.4. During the test the temperature in the test-room must be maintained at between 20 oC and 30 oC or at a higher temperature if the manufacturer agrees.2.5. The test is carried out without interruption in conformity with the following particulars:2.5.1. time taken to pass from zero speed to initial test speed: 10 minutes;2.5.2. initial test speed: prescribed maximum speed for the type of tyre, less 40 km/h in the case of the smooth wheel having 1,70 m ± 1 % in diameter or less 30 km/h in the case of the smooth wheel having 2 m ± 1 % in diameter;2.5.3. successive speed increments: 10 km/h;2.5.4. duration of test at each speed step except the last: 10 minutes;2.5.5. duration of test at last speed step: 20 minutes;2.5.6. maximum test speed: prescribed maximum speed for the type of tyre, less 10 km/h in the case of the smooth wheel having 1,70 m ± 1 % in diameter or equal to prescribed maximum speed in the case of the smooth wheel having 2 m ± 1 % in diameter.3. Equivalent test methodsIf a method other than that described in section 2 is used, its equivalence must be demonstrated.PART B: COMMERCIAL VEHICLE TYRES [31]1. Preparing the tyre1.1. Mount a new tyre on the test rim specified by the manufacturer pursuant to point 6.11 of Appendix 1 to Annex I.1.2. Use a new inner tube or combination of inner tube, valve and flap (as required) when testing tyres with inner tubes.1.3. Inflate the tyre to the pressure corresponding to the pressure index specified by the tyre manufacturer, pursuant to point 6.14 of Appendix 1 to Annex I.1.4. Condition the tyre and wheel assembly at test room temperature for not less than three hours.1.5. Readjust the tyre pressure to that specified in point 1.3.2. Test procedure2.1. Mount the tyre and wheel assembly on the test axle and press it against the outer face of a smooth power-driven test drum 1,70 m ± 1 % in diameter having a surface at least as wide as the tyre tread.2.2. Apply to test axle a series of test loads expressed as a percentage of the load indicated in Appendix 2, opposite the load index moulded on the sidewall of the tyre, in accordance with the load/speed test programme shown in the Table below. When the tyre has load capacity indices for both single and twin utilisation, the reference load for single utilisation is taken as the basis for the test loads.2.3. The tyre pressure must not be corrected throughout the test and the test load must be kept constant throughout each of the three test stages.2.4. During the test the temperature in the test room must be maintained at between 20 oC and 30 oC or at a higher temperature if the manufacturer so agrees.2.5. The load/speed test programme must be carried out without interruption.3. Equivalent test methodsIf a method other than that described in section 2 is used, its equivalence must be demonstrated.LOAD/SPEED TEST PROGRAMMELoad index | Tyre speed category symbol | Test-drum speed (rev/min) (1) | Load placed on the wheel as a percentage of the load corresponding to the load index || | Radial-ply tyre | Diagonal (bias-ply) tyre | 7 h. | 16 h. | 24 h. |122 or more | F | 100 | 100 | 66 % | 84 % | 101 % || G | 125 | 100 | | | || J | 150 | 125 | | | || K | 175 | 150 | | | || L | 200 | — | | | || M | 225 | — | | | |121 or less | F | 100 | 100 | | | || G | 125 | 125 | | | || J | 150 | 150 | | | || K | 175 | 175 | | | || L | 200 | 175 | 70 % | 88 % | 106 % || | | | 4 h. | 6 h. | || M | 250 | 200 | 75 % | 97 % | 114 % || N | 275 | — | 75 % | 97 % | 114 % || P | 300 | — | 75 % | 97 % | 114 % |(1) ‘Special-use’ tyres (see point 2.1.3. of Annex II) should be tested at a speed equal to 85 % of the test-drum speed prescribed above for equivalent normal tyres. |Appendix 8VARIATION OF LOAD CAPACITY WITH SPEEDCommercial-vehicle tyresRADIAL AND DIAGONAL(see Annex II, points 2.30, 2.31 and 6.2.4)Speed(km/h) | Variation of load capacity (%) || All load indices | Load indices (1) ≥ 122 | Load indices (1) ≤ 121 || Speed category symbol | Speed category symbol | Speed category symbol || F | G | J | K | L | M | L | M | N | P (2) |0 | + 150 | + 150 | + 150 | + 150 | + 150 | + 150 | + 110 | + 110 | + 110 | + 110 |5 | + 110 | + 110 | + 110 | + 110 | + 110 | + 110 | + 90 | + 90 | + 90 | + 90 |10 | + 80 | + 80 | + 80 | + 80 | + 80 | + 80 | + 75 | + 75 | + 75 | + 75 |15 | + 65 | + 65 | + 65 | + 65 | + 65 | + 65 | + 60 | + 60 | + 60 | + 60 |20 | + 50 | + 50 | + 50 | + 50 | + 50 | + 50 | + 50 | + 50 | + 50 | + 50 |25 | + 35 | + 35 | + 35 | + 35 | + 35 | + 35 | + 42 | + 42 | + 42 | + 42 |30 | + 25 | + 25 | + 25 | + 25 | + 25 | + 25 | + 35 | + 35 | + 35 | + 35 |35 | + 19 | + 19 | + 19 | + 19 | + 19 | + 19 | + 29 | + 29 | + 29 | + 29 |40 | + 15 | + 15 | + 15 | + 15 | + 15 | + 15 | + 25 | + 25 | + 25 | + 25 |45 | + 13 | + 13 | + 13 | + 13 | + 13 | + 13 | + 22 | + 22 | + 22 | + 22 |50 | + 12 | + 12 | + 12 | + 12 | + 12 | + 12 | + 20 | + 20 | + 20 | + 20 |55 | + 11 | + 11 | + 11 | + 11 | + 11 | + 11 | + 17,5 | + 17,5 | + 17,5 | + 17,5 |60 | + 10 | + 10 | + 10 | + 10 | + 10 | + 10 | + 15,0 | + 15,0 | + 15,0 | + 15,0 |65 | + 7,5 | + 8,5 | + 8,5 | + 8,5 | + 8,5 | + 8,5 | + 13,5 | + 13,5 | + 13,5 | + 13,5 |70 | + 5,0 | + 7,0 | + 7,0 | + 7,0 | + 7,0 | + 7,0 | + 12,5 | + 12,5 | + 12,5 | + 12,5 |75 | + 2,5 | + 5,5 | + 5,5 | + 5,5 | + 5,5 | + 5,5 | + 11,0 | + 11,0 | + 11,0 | + 11,0 |80 | 0 | + 4,0 | + 4,0 | + 4,0 | + 4,0 | + 4,0 | + 10,0 | + 10,0 | + 10,0 | + 10,0 |85 | − 3 | + 2,0 | + 3,0 | + 3,0 | + 3,0 | + 3,0 | + 8,5 | + 8,5 | + 8,5 | + 8,5 |90 | − 6 | 0 | + 2,0 | + 2,0 | + 2,0 | + 2,0 | + 7,5 | + 7,5 | + 7,5 | + 7,5 |95 | − 10 | − 2,5 | + 1,0 | + 1,0 | + 1,0 | + 1,0 | + 6,5 | + 6,5 | + 6,5 | + 6,5 |100 | − 15 | − 5 | 0 | 0 | 0 | 0 | + 5,0 | + 5,0 | + 5,0 | + 5,0 |105 | | − 8 | − 2 | 0 | 0 | 0 | + 3,75 | + 3,75 | + 3,75 | + 3,75 |110 | | − 13 | − 4 | 0 | 0 | 0 | + 2,5 | + 2,5 | + 2,5 | + 2,5 |115 | | | − 7 | − 3 | 0 | 0 | + 1,25 | + 1,25 | + 1,25 | + 1,25 |120 | | | − 12 | − 7 | 0 | 0 | 0 | 0 | 0 | 0 |125 | | | | | | 0 | − 2,5 | 0 | 0 | 0 |130 | | | | | | 0 | − 5 | 0 | 0 | 0 |135 | | | | | | | − 7,5 | − 2,5 | 0 | 0 |140 | | | | | | | − 10 | − 5 | 0 | 0 |145 | | | | | | | | − 7,5 | − 2,5 | 0 |150 | | | | | | | | − 10 | − 5 | 0 |155 | | | | | | | | | − 7,5 | − 2,5 |160 | | | | | | | | | − 10 | − 5 |(1) The load capacity indices refer to single operations (see point 2.28.2 of Annex II).(2) Load variations are not allowed above 160 km/h.

DEFINITIONS2. For the purpose of this Directive:2.1. ‘approval of a vehicle’ means the approval of a vehicle type with regard to its tyres, including temporary-use spare tyres;2.2. ‘vehicle type’ means a range of vehicles which do not differ significantly, at least as regards each variant of the vehicle type, in such essential aspects as would affect the tyre size designation, the speed category symbol or the load capacity index:2.3. ‘wheel’ means a complete wheel consisting of a rim and a wheel disc;2.4. ‘temporary-use spare wheel’ means a wheel different from one of the normal wheels on the vehicle type;2.5. ‘unit’ means an assembly of a wheel and tyre;2.6. ‘normal unit’ means a unit which is capable of being fitted to the vehicle for normal operation;2.7. ‘spare unit’ means a unit which is intended to be exchanged for a normal unit in case of malfunction of the latter. A ‘spare unit’ may be either of the following:2.7.0. ‘normal spare unit’, which is a unit that conforms to the normal unit of the vehicle type;2.7.1. ‘temporary-use spare unit’, which is a unit that differs from the normal units of the vehicle type with regard to their principal characteristics (e.g. their tyre-size designation, functional dimensions, conditions of use or structure). It is intended for temporary use under restricted conditions. Temporary-use spare units may be of the following categories:2.7.1.1. category 1a unit consisting of a wheel which conforms to a wheel of a normal unit and a tyre which has principal characteristics (e.g. dimensions, structure) different to the normal tyre;2.7.1.2. category 2a unit consisting of a wheel and a tyre both having principal characteristics different to the normal unit and intended to be carried on the vehicle with the tyre inflated to the pressure specified for temporary use;2.7.1.3. category 3a unit consisting of a normal wheel and a tyre having principal characteristics different to a normal tyre and intended to be carried on the vehicle with the tyre folded and not inflated;2.7.1.4. category 4a unit consisting of a wheel and tyre both having principal characteristics different to a normal unit and intended to be carried on the vehicle with the tyre folded and not inflated;2.8. ‘maximum mass’ means the maximum value stated by the vehicle manufacturer to be technically permissible for the vehicle;2.9. ‘maximum axle load’ means the maximum value stated by the vehicle manufacturer to be technically permissible for the total vertical force between the contact surfaces of the tyres of the axle in question and the ground and resulting from the part of the vehicle mass supported by that axle. The sum of the axle loads may be greater than the value corresponding to the maximum mass of the vehicle;2.10. ‘functional dimensions’ means dimensions derived from the size designation of the wheels and/or tyres (e.g. diameter, width, aspect ratio) and from the mounting of the unit to the vehicle (e.g. wheel offset);2.11. ‘maximum design speed’ means the maximum speed approved for the vehicle type inclusive of the tolerance allowed for the conformity checks of the series production.3. REQUIREMENTS FOR VEHICLES WITH REGARD TO THE FITTING OF THEIR TYRES3.1. General2001/43/EC Art. 1 pt. 5 and Annex pt. 73.1.1. Subject to the provisions of point 3.7.4., every tyre fitted to a vehicle, including where applicable any spare, must bear the EC type-approval mark(s) as specified in section 4 of Annex I or the type-approval mark indicating compliance with UN/ECE Regulations Nos. 30 or 54. UN/ECE type-approval marks are considered to be equivalent only to the EC type-approval marks granted pursuant to Annex II.92/23/EEC3.2. Tyre fitment3.2.1. All of the tyres fitted to a vehicle, excluding any temporary use spare, must have the same structure (see Annex II point 2.3).3.2.2. All of the tyres fitted to one axle must be of the same type (see Annex II point 2.1).3.2.3. The space in which the wheel revolves must be such as to allow unrestricted movement when using the maximum permissible size of tyres within the suspension and steering constraints provided by the vehicle manufacturer.3.3. Load capacity3.3.1. Subject to the provisions of point 3.7, the maximum load rating (see Annex II point 2.31) of every tyre, including a spare tyre (if provided) with which a vehicle is fitted is:3.3.1.1. in the case of a vehicle fitted with tyres of the same type in single formation: at least equal to half of the maximum axle load (see point 2.9) for the most heavily loaded axle, as declared by the manufacturer of the vehicle;3.3.1.2. in the case of a vehicle fitted with tyres of more than one type, in single formation: at least equal to half of the maximum axle load (see point 2.9), as declared by the manufacturer of the vehicle, in respect of the relevant axle;3.3.1.3. in the case of a vehicle fitted with passenger car tyres in dual (twin) formation: at least equal to 0,27 times the maximum axle load, as declared by the manufacturer of the vehicle, in respect of the relevant axle;3.3.1.4. in the case of axles fitted with commercial vehicle tyres in dual (twin) formation: at least equal to 0,25 times, with reference to the load capacity index for dual application, the maximum axle load as declared by the manufacturer of the vehicle, in respect of the relevant axle.3.4. Speed capacity3.4.1. Every tyre with which a vehicle is normally fitted must have a speed category symbol (see Annex II, point 2.29) compatible with the maximum design speed of the vehicle (as declared by the vehicle manufacturer) or the applicable load/speed combination (see Annex II, point 2.30).3.4.2. The above specification does not apply:3.4.2.1. in the case of temporary use spare units for which point 3.8 applies;3.4.2.2. in the case of vehicles normally equipped with ordinary tyres and occasionally supplied with snow tyres.However, in this case the speed category symbol of the snow tyres must correspond to a speed either greater than the maximum design speed of the vehicle (as declared by the vehicle manufacturer) or not less than 160 km/h (or both).If, nevertheless, the maximum design speed of the vehicles (as declared by the vehicle manufacturer) is greater than the speed corresponding to the speed category symbol of the snow tyres a maximum speed warning label, specifying the maximum speed capability of the snow tyres, must be displayed inside the vehicle in a prominent position readily visible to the driver.3.5.

However, no vehicle other than a vehicle of category M1 may be fitted with a temporary-use spare tyre.3.5.2. Every vehicle provided with a temporary-use spare unit must be provided with supplementary information clearly and permanently displayed on the temporary-use spare unit or on the vehicle near the spare unit or in the driver's handbook. At least the following information must be given:3.5.2.1. an instruction to drive with caution when the temporary-use spare unit is fitted, and to install a normal unit as soon as possible;3.5.2.2. a statement that operation of the vehicle is not permitted with more than one temporary-use spare unit fitted at the same time;3.5.2.3. a clear indication of the inflation pressure specified by the vehicle manufacturer for the tyre of the temporary-use spare unit;3.5.2.4. for vehicles equipped with category 3 or category 4 temporary-use spare units, a description of the procedure for inflating the tyre to the pressure specified for temporary use by means of the device referred to in point 3.6;3.6. Inflating device of temporary-use spare unit:3.6.1. if the vehicle is equipped with a category 3 or category 4 temporary-use spare unit, a device must be provided on the vehicle which permits the tyre to be inflated to the pressure specified for temporary use within a maximum of five minutes.3.7. Special cases3.7.1. In the case of trailers of categories 01 and 02 with operating speeds restricted to 100 km/h or less fitted with passenger car tyres in single formation, the maximum load rating of every tyre must be at least equal to 0,45 times the maximum mass for the most heavily loaded axle, as declared by the manufacturer of the trailer. For tyres in dual (twin) formation this factor is 0,24.3.7.2. In the case of some special vehicles fitted with commercial vehicle tyres, the table ‘Variation of Load Capacity with Speed’ (see point 2.30 and Appendix 8 to Annex II) is not to be applied. In those cases the tyre maximum load ratings to check against the maximum axle loads (see points 3.3.1.2 and 3.3.1.4 of this Annex) are determined by multiplying the load corresponding to the load capacity index by an appropriate coefficient which is related to the type of vehicle and its use rather than to the maximum design speed of the vehicle. In such cases point 3.4.1 of this Annex does not apply. The appropriate coefficients are as follows:3.7.2.1. 1,10 in the case of vehicles of category M3 when the vehicle is carrying standing passengers and the operating speed does not exceed 60 km/h. However, for operational reasons Member States may allow the operating speed to be increased to 80 km/h;3.7.2.2. 1,15 in the case of such vehicles (M3) if they are intended for use only on urban routes with frequent stops;3.7.2.3. 1,10 in the case of public utility vehicles of category N used at slow speeds over short distances in urban and suburban applications such as road sweepers or refuse collectors.3.7.3. When a motor vehicle of category M1 is towing a trailer, the additional load imposed at the trailer coupling device may cause the tyre maximum load ratings to be exceeded, but not by more than 15 %, provided that the operating speed is restricted to 100 km/h or less and the inflation pressure increased by at least 0,2 bar is applied.3.7.4. In the case of a vehicle which is fitted with tyres which are not passenger car tyres nor commercial vehicle tyres due to special conditions of use (e.g. agricultural tyres, industrial truck tyres, motor cycle tyres) the requirements of Annex II do not apply provided that the approval authority is satisfied that the tyres fitted are suitable for the operating conditions of the vehicle.3.8. Specifications for temporary-use spare units3.8.1. Every temporary-use spare tyre must have a speed category at least equal to 120 km/h (speed category symbol L).3.8.2. When fitted to the vehicle for temporary use the outward facing surface of the wheel must exhibit a distinctive colour or colour pattern which is clearly different from the colour(s) of the normal units. If it is possible to attach a wheel cover to the temporary-use spare unit the distinctive colour or colour pattern must not be obscured by this wheel cover.3.8.3. A maximum speed warning symbol must be permanently displayed on the outer face of the wheel in a prominent position and in accordance with the diagram below:(...PICT...)_____________2001/43/EC Art. 1 pt. 5 and Annex pt. 8ANNEX VTYRE/ROAD NOISE EMISSION1.

IntroductionThe presented method contains specifications on measuring instruments, measurement conditions and the measurement method, in order to obtain the noise level of a set of tyres mounted on a test vehicle rolling at high speed on a specified road surface. The maximum sound pressure level is to be recorded, when the test vehicle is coasting, by remote-field microphones; the final result of a reference speed is obtained from a linear regression analysis. Such test results cannot be related to tyre noise measured during acceleration under power or deceleration during braking.1. Measuring instruments1.1. Acoustic measurementsThe sound level meter or the equivalent measuring system, including the windscreen recommended by the manufacturer, shall at least meet the requirements of Type 1 instruments in accordance with IEC 60651, second edition.The measurements shall be made using the frequency weighting A, and the time weighting F.When using a system that includes a periodic monitoring of the A-weighted sound level, a reading should be made at a time interval not greater than 30 ms.2001/43/EC Art. 1 pt. 5 and Annex pt. 8 (adapted)1.1.1. CalibrationAt the beginning and at the end of every measurement session, the entire measurement system shall be checked by means of a sound calibrator that fulfils the requirements for sound calibrators of at least precision Class 1 according to IEC 942:1988. Without any further adjustment the difference between the readings of two consecutive checks shall be less than or equal to 0,5 dB. If this value is exceeded, the results of the measurements obtained after the previous satisfactory check shall be discarded.2001/43/EC Art. 1 pt. 5 and Annex pt. 81.1.2. Compliance with requirementsThe compliance of the sound calibration device with the requirements of IEC 60942:1988 shall be verified once a year and the compliance of the instrumentation system with the requirements of IEC 60651:1979/A1:1993, second edition, shall be verified at least every two years by a laboratory which is authorised to perform calibrations traceable to the appropriate standards.1.1.3. Positioning of the microphoneThe microphone (or microphones) must be located at a distance of 7,5 m ± 0,05 m from track reference line CC′ (figure 1) and 1,2 m ± 0,02 m above the ground. Its axis of maximum sensitivity must be horizontal and perpendicular to the path of the vehicle (line CC′).1.2. Speed measurementsThe vehicle speed shall be measured with instruments with an accuracy of ± 1 km/h or better when the front end of the vehicle has reached line PP′ (figure 1).1.3. Temperature measurementsMeasurements of air as well as test surface temperature are mandatory. The temperature measuring devices shall be accurate within ± 1 oC.1.3.1. Air temperatureThe temperature sensor is to be positioned in an unobstructed location close to the microphone in such a way that it is exposed to the airflow and protected from direct solar radiation. The latter may be achieved by any shading screen or similar device. The sensor should be positioned at a height of 1,2 m ± 0,1 m above the test surface level in order to minimise the influence of the test surface thermal radiation at low airflows.1.3.2. Test surface temperatureThe temperature sensor is to be positioned in a location where the temperature measured is representative of the temperature in the wheel tracks, without interfering with the sound measurement.If an instrument with a contact temperature sensor is used, heat-conductive paste shall be applied between the surface and the sensor to ensure adequate thermal contact.If a radiation thermometer (pyrometer) is used, the height should be chosen to ensure that a measuring spot with a diameter of ≥ 0,1 m is covered.1.4. Wind measurementThe device must be capable of measuring the wind speed with a tolerance of ± 1 m/s. The wind shall be measured at microphone height. The wind direction with reference to the driving direction shall be recorded.2. Conditions of measurement2.1. Test siteThe test site must consist of a central section surrounded by a substantially flat test area. The measuring section must be level; the test surface must be dry and clean for all measurements. The test surface shall not be artificially cooled during or prior to the testing.The test track must be such that the conditions of a free sound field between the sound source and the microphone are attained to within 1 dB(A). These conditions shall be deemed to be met if there are no large sound reflecting objects such as fences, rocks, bridges or buildings within 50 m of the centre of the measuring section. The surface of the test track and the dimensions of the test site shall be in accordance with Appendix 2 of this Annex.A central part of at least 10 m radius shall be free of powdery snow, tall grass, loose soil, cinders or the like. There must be no obstacle which could affect the sound field within the vicinity of the microphone and no persons shall stand between the microphone and the sound source. The operator carrying out the measurements and any observers attending the measurements must position themselves so as not to affect the readings of the measuring instruments.2.2. Meteorological conditionsMeasurements shall not be made under poor atmospheric conditions. It must be ensured that the results are not affected by gusts of wind. Testing shall not be performed if the wind speed at the microphone height exceeds 5 m/s.Measurements shall not be made if the air temperature is below 5 oC or above 40 oC or the test surface temperature is below 5 oC or above 50 oC.2.3. Ambient noiseThe background sound level (including any wind noise) shall be at least 10 dB(A) less than the measured tyre-road sound emission. A suitable windscreen may be fitted to the microphone provided that account is taken of its effect on the sensitivity and directional characteristics of the microphone.Any measurement affected by a sound peak which appears to be unrelated to the characteristics of the general sound level of tyres shall be ignored.2.4. Test vehicle requirements2.4.1. GeneralThe test vehicle shall be a motor vehicle and be fitted with four single tyres on just two axles.2.4.2. Vehicle loadThe vehicle must be loaded such as to comply with the test tyre loads as specified in point 2.5.2. .2.4.3. WheelbaseThe wheelbase between the two axles fitted with the test tyres shall for Class C1 be less than 3,50 m and for Class C2 and Class C3 tyres be less than 5 m.2.4.4. Measures to minimise vehicle influence on sound level measurementsTo ensure that tyre noise is not significantly affected by the test vehicle design the following requirements and recommendations are given.Requirements:(a) Spray suppression flaps or other extra device to suppress spray shall not be fitted.(b) Addition or retention of elements in the immediate vicinity of the rims and tyres, which may screen the emitted sound, is not permitted.(c) Wheel alignment (toe in, camber and castor) shall be in full accordance with the vehicle manufacturer's recommendations.(d) Additional sound absorbing material may not be mounted in the wheel housings or under the underbody.(e) Suspension shall be in such a condition that it does not result in an abnormal reduction in ground clearance when the vehicle is loaded in accordance with the testing requirement. If available, body level regulation systems shall be adjusted to give a ground clearance during testing which is normal for unladen conditions.Recommendations to avoid parasitic sound:(a) Removal or modification of components on the vehicle that any contribute to the background sound of the vehicle is recommended. Any removals or modifications shall be recorded in the test report.(b) During testing it should be ascertained that brakes are not poorly released, causing brake noise.(c) It should be ascertained that electric cooling fans are not operating.(d) Windows and sliding roof of the vehicle shall be closed during testing.2.5. Tyres2.5.1. GeneralFour identical tyres of the same type and range must be fitted to the test vehicle. In the case of tyres with a load capacity index in excess of 121 and without any dual fitting indication, two of these tyres of the same type and range must be fitted to the rear axle of the test vehicle; the front axle must be fitted with tyres of a size suitable for the axle load and planed down to the minimum depth in order to minimise the influence of tyre/road contact noise while maintaining a sufficient level of safety. Winter tyres that in certain Member States may be equipped with studs intended to enhance friction shall be tested without this equipment. Tyres with special fitting requirements shall be tested in accordance with these requirements (e.g. rotation direction). The tyres must have full tread depth before being run-in.Tyres are to be tested on rims permitted by the tyre manufacturer.2.5.2. Tyre loadsThe test load Qt for each tyre on the test vehicle shall be 50 % to 90 % of the reference load Qr, but the average test load Qt,avr of all tyres shall be 75 % ± 5 % of the reference load Qr.For all tyres the reference load Qr corresponds to the maximum mass associated with the load capacity index of the tyre. In the case where the load capacity index is constituted by two numbers divided by slash (/), reference shall be made to the first number.2.5.3. Tyre inflation pressureEach tyre fitted on the test vehicle shall have a test pressure Pt not higher than the reference pressure Pr and within the interval:(...PICT...)where Pr is the pressure corresponding to the pressure index marked on the sidewall.For Class C1 the reference pressure is Pr = 250 kPa for ‘standard’ tyres and 290 kPa for ‘reinforced’ tyres, the minimum test pressure shall be Pt = 150 kPa.2.5.4. Preparations prior to testingThe tyres should be ‘run-in’ prior to testing to remove compound nodules or other tyre pattern characteristics resulting from the moulding process. This will normally require the equivalent of about 100 km of normal use on the road.The tyres fitted to the test vehicle shall rotate in the same direction as when they were run-in.Prior to testing tyres shall be warmed up by running under test conditions.3. Method of testing3.1. General conditionsFor all measurements the vehicle must be driven in a straight line over the measuring section (AA′ to BB′) in such a way that the median longitudinal plane of the vehicle is as close as possible to the line CC′.When the front end of the test vehicle has reached the line AA′, the vehicle's driver must have put the gear selector on neutral position and switched off the engine. If abnormal noise (e.g. ventilator, self-ignition) is emitted by the test vehicle during the measurement, the test must be repeated.3.2. Nature and number of measurementsThe maximum sound level expressed in A-weighted decibels (dB(A)) shall be measured to the first decimal place as the vehicle is coasting between lines AA′ and BB′ (figure 1 — front end of the vehicle on line AA′, rear end of the vehicle on line BB'). This value will constitute the result of the measurement.At least four measurements shall be made on each side of the test vehicle at test speeds lower than the reference speed specified in paragraph 4.1. and at least four measurements at test speeds higher than the reference speed. The speeds shall be approximately equally spaced over the speed range specified in paragraph 3.3.3.3. Test speedsThe test vehicle speeds shall be within the range:(i) from 70 km/h to 90 km/h for Class C1 and Class C2 tyres;(ii) from 60 km/h to 80 km/h for Class C3 tyres.4. Interpretation of resultsThe measurement shall be invalid if an abnormal discrepancy between the maximum value and the other values is recorded.4.1. Determination of test resultReference speed Vref used to determine the final result will be:(i) 80 km/h for Class C1 and Class C2 tyres;(ii) 70 km/h for Class C3 tyres.4.2. Regression analysis of noise measurementsThe (not temperature corrected) tyre-road noise level LR in dB(A) is determined by a regression analysis according to:(...PICT...)where:(...PICT...)is the mean value of the noise levels Li, measured in dB(A):(...PICT...)n is the measurement number (n ≥ 16),(...PICT...)is the mean value of logarithms of speeds vi:(...PICT...)With(...PICT...)a is the slope of the regression line in dB(A):(...PICT...)4.3. Temperature correction2001/43/EC Art. 1 pt. 5 and Annex pt. 8 (adapted)For Class C1 and Class C2 tyres, the final result shall be normalised to a test surface reference temperature θ ref by applying a temperature correction, according to the following:(...PICT...)where θ is the measured test surface temperature,θref = 20 oC,For Class C1 tyres, the coefficient K is – 0,03 dB(A)/oC when θ > θref and K is – 0,06 dB(A)/oC when θ < θref.For Class C2 tyres, the coefficient K is – 0,02 dB(A)/oC.2001/43/EC Art. 1 pt. 5 and Annex pt. 8If the measured test surface temperature does not change by more than 5 oC within all measurements necessary for the determination of the sound level of one set of tyres, the temperature correction may be made only on the final reported tyre-road sound level as indicated above, utilising the arithmetic mean value of the measured temperatures. Otherwise each measured sound level Li shall be corrected, utilising the temperature at the time of the sound recording.There will be no temperature correction for Class C3 tyres.4.4. In order to take account of any measuring instrument inaccuracies, the results according to point 4.3. shall be reduced by 1 dB(A).4.5. The final result, the temperature corrected tyre-road noise level LR(θref) in dB(A), shall be rounded down to the nearest lower whole value.Figure 1:Microphone Positions for the Measurement(...PICT...)Appendix 2TEST REPORTThe test report shall include the following information:(a) meteorological conditions inclusive of air and test surface temperature for each test run,(b) date and method of check on compliance of the test surface with ISO 10844:1994,(c) test rim width,(d) tyre data: manufacturer, brand name, trade name, size, load index, reference pressure,(e) test vehicle description and wheelbase,(f) type test load Qt in N and in per cent of the reference load Qr for each test tyre, average test load Qt,avr in N and in per cent of the reference load Qr,(g) cold inflation pressure in kPa for each test tyre,(h) test speeds when the vehicle passed line PP′,(i) maximum A-weighted sound levels for each test run and each microphone,(j) the test result LR: A-weighted sound level in decibel at reference speed, corrected for temperature (if applicable), rounded down to the nearest lower whole value.(k) regression line slope._____________2001/43/EC Art. 1 pt. 5 and Annex pt. 9 (adapted)ANNEX VISPECIFICATIONS FOR THE TEST SITE1. IntroductionThis Annex describes the specifications relating to the physical characteristics and the laying of the test track. These specifications based on a special standard [32] describe the required physical characteristics as well as the test methods for these characteristics.2. Required characteristics of the surfaceA surface is considered to conform to this standard provided that the texture and voids content or sound absorption coefficient have been measured and found to fulfil all the requirements of points 2.1. to 2.4. and provided that the design requirements (point 3.2.) have been met.2.1. Residual voids contentThe residual voids content (VC) of the test track paving mixture shall not exceed 8 %. For the measurement procedure, see point 4.1.2.2. Sound absorption coefficientIf the surface fails to comply with the residual voids content requirement, the surface is acceptable only if its sound absorption coefficient α ≤ 0,10. For the measurement procedure, see point 4.2. The requirement of points 2.1. and 2.2. is also met if only sound absorption has been measured and found to be α ≤ 0,10.Note: The most relevant characteristic is the sound absorption, although the residual voids content is more familiar among road constructors. However, sound absorption needs to be measured only if the surface fails to comply with the voids requirement. This is justified because the residual voids content has relatively large uncertainties in terms of both measurements and relevance and some surfaces may therefore erroneously be rejected when based only on the voids measurement.2.3. Texture depthThe texture depth (TD) measured according to the volumetric method (see point 4.3. ) shall be:TD ≥ 0,4 mm2.4. Homogeneity of the surfaceEvery practical effort shall be taken to ensure that the surface is made to be as homogeneous as possible within the test area. This includes the texture and voids content, but it should also be observed that if the rolling process results in more effective rolling at some places than others, the texture may be different and unevenness causing bumps may also occur.2.5. Period of testingIn order to check whether the surface continues to conform to the texture and voids content or sound absorption requirements stipulated in this Annex, periodic testing of the surface shall be carried out at the following intervals:(a) For residual voids content (VC) or sound absorption (α):when the surface is new;if the surface meets the requirements when new, no further periodical testing is required. If it does not meet the requirement when it is new, it may do so later because surfaces tend to become clogged and compacted with time.(b) For texture depth (TD):when the surface is new;when the noise testing starts (NB: not before four weeks after laying);then every twelve months.3. Test surface design3.1. AreaWhen designing the test track layout it is important to ensure that, as a minimum requirement, the area traversed by the vehicles running through the test strip is covered with the specified test material with suitable margins for safe and practical driving. This will require that the width of the track is at least 3 m and the length of the track extends beyond lines AA and BB by at least 10 m at either end. Figure 1 shows a plan of a suitable test site and indicates the minimum area which shall be machine laid and machine compacted with the specified test surface material. According to Annex V, Appendix 1, point 3.2., measurements have to be made on each side of the vehicle. This can be made either by measuring with two microphone locations (one on each side of the track) and driving in one direction, or measuring with a microphone only on one side of the track but driving the vehicle in two directions. If the latter method is used, then there are no surface requirements on that side of the track where there is no microphone.Figure 1Minimum requirements for test surface areaThe shaded part is called ‘Test Area’.(...PICT...)3.2. Design and preparation of the surface3.2.1. Basic design requirementsThe test surface shall meet four design requirements:3.2.1.1. It shall be a dense asphaltic concrete.3.2.1.2. The maximum chipping size shall be 8 mm (tolerances allow from 6,3 mm to 10 mm).3.2.1.3. The thickness of the wearing course shall be ≥ 30 mm.3.2.1.4. The binder shall be a straight penetration grade bitumen without modification.3.2.2. Design guidelinesAs a guide to the surface constructor, an aggregate grading curve which will give desired characteristics is shown in Figure 2. In addition, Table 1 gives some guidelines in order to obtain the desired texture and durability. The grading curve fits the following formula:P (% passing) = 100(d/dmax)1/2where: | | |d | = | square mesh sieve size, in mm |dmax | = | 8 mm for the mean curve || = | 10 mm for the lower tolerance curve || = | 6,3 mm for the upper tolerance curve |Figure 2:Grading curve of the aggregate in the asphaltic mix with tolerances(...PICT...)In addition to the above, the following recommendations are made:(a) The sand fraction (0,063 mm < square mesh sieve size < 2 mm) shall include no more than 55 % natural sand and at least 45 % crushed sand.(b) The base and sub-base shall ensure a good stability and evenness, according to best road construction practice.(c) The chippings shall be crushed (100 % crushed faces) and of a material with a high resistance to crushing.(d) The chippings used in the mix shall be washed.(e) No extra chippings shall be added onto the surface.(f) The binder hardness expressed as PEN value shall be 40-60, 60-80 or even 80-100 depending on the climatic conditions of the country. The rule is that as hard a binder as possible shall be used, provided this is consistent with common practice.(g) The temperature of the mix before rolling shall be chosen so as to achieve by subsequent rolling the required voids content. In order to increase the probability of satisfying the specifications of points 2.1. to 2.4., the compactness shall be studied not only by an appropriate choice of mixing temperature, but also by an appropriate number of passings and by the choice of compacting vehicle.Table 1Design guidelines| Target values | Tolerances || By total mass of mix | By mass of the aggregate | |Mass of stones, square mesh sieve (SM) > 2 mm | 47,6 % | 50,5 % | ± 5 |Mass of sand 0,063 < SM < 2 mm | 38,0 % | 40,2 % | ± 5 |Mass of filler SM <0,063 mm | 8,8 % | 9,3 % | ± 2 |Mass of binder (bitumen) | 5,8 % | N.A. | ± 0,5 |Max. chipping size | 8 mm | | 6,3 – 10 |Binder hardness | (see point 3.2.2. (f)) | |Polished stone value (PSV) | > 50 | | |Compactness, relative to Marshall compactness | 98 % | | |4. Test method4.1. Measurement of the residual voids contentFor the purpose of this measurement, cores have to be taken from the track in at least four different positions which are equally distributed in the test area between lines AA and BB (see figure 1). In order to avoid non-homogeneity and unevenness in the wheel tracks, cores should not be taken in wheel tracks themselves, but close to them. Two cores (minimum) should be taken close to the wheel tracks and one core (minimum) should be taken approximately midway between the wheel tracks and each microphone location.If there is a suspicion that the condition of homogeneity is not met (see point 2.4.), cores shall be taken from more locations within the test area.The residual voids content has to be determined for each core, then the average value from all cores shall be calculated and compared with the requirement of point 2.1. In addition, no single core shall have a voids value which is higher than 10 %.The test surface constructor is reminded of the problem which may arise when the test area is heated by pipes or electrical wires and cores must be taken from this area. Such installations must be carefully planned with respect to future core drilling locations. It is recommended to leave a few locations of size approximately 200 mm × 300 mm where there are no wires/pipes or where the latter are located deep enough in order not to be damaged by cores taken from the surface layer.4.2. Sound absorption coefficientThe sound absorption coefficient (normal incidence) shall be measured by the impedance tube method using the procedure specified in ISO 10534-1:1996: ‘Acoustics — Determination of sound absorption coefficient and impedance by a tube method’.Regarding test specimens, the same requirements shall be followed as regarding the residual voids content (see point 4.1). The sound absorption shall be measured in the range between 400 Hz and 800 Hz and in the range between 800 Hz and 1 600 Hz (at least at the centre frequencies of third octave bands) and the maximum values shall be identified for both of these frequency ranges. Then these values, for all test cores, shall be averaged to constitute the final result.4.3. Volumetric macrotexture measurementFor the purpose of this standard, texture depth measurements shall be made on at least 10 positions evenly spaced along the wheel tracks of the test strip and the average value taken to compare with the specified minimum texture depth. See Standard ISO 10844:1994 for description of the procedure.5. Stability in time and maintenance5.1. Age influenceIn common with any other surfaces, it is expected that the tyre-road noise level measured on the test surface may increase slightly during the first 6 — 12 months after construction.The surface will achieve its required characteristics not earlier than four weeks after construction. The influence of age on the noise from trucks is generally less than that from cars.Stability over time is determined mainly by polishing and compaction by vehicles driving on the surface. It shall be periodically checked as stated in point 2.5.5.2. Maintenance of the surfaceLoose debris or dust which could significantly reduce the effective texture depth must be removed from the surface. In countries with winter climates, salt is sometimes used for de-icing. Salt may alter the surface temporarily or even permanently in such a way as to increase noise and is therefore not recommended.5.3. Repaving the test areaIf it is necessary to repave the test track, it is usually unnecessary to repave more than the test strip (of 3 m width in figure 1) where vehicles are driving, provided the test area outside the strip met the requirement of residual voids content or sound absorption when it was measured.6. Documentation of the test surface and of tests performed on it6.1. Documentation of the test surfaceThe following data shall be given in a document describing the test surface:6.1.1. The location of the test track.6.1.2. Type of binder, binder hardness, type of aggregate, maximum theoretical density of the concrete (DR), thickness of the wearing course and grading curve determined from cores from the test track.6.1.3. Method of compaction (e.g. type of roller, roller mass, number of passes).6.1.4. Temperature of the mix, temperature of the ambient air and wind speed during laying of the surface.6.1.5. Date when the surface was laid and contractor.6.1.6. All or at least the latest test result, including:6.1.6.1. the residual voids content of each core;6.1.6.2. the locations in the test area from where the cores for voids measurements have been taken;6.1.6.3. the sound absorption coefficient of each core (if measured). Specify the results both for each core and each frequency range as well as the overall average;6.1.6.4. the locations in the test area from where the cores for absorption measurement have been taken;6.1.6.5. texture depth, including the number of tests and standard deviation;6.1.6.6. the institution responsible for tests according to points 6.1.6.1. and 6.1.6.2. and the type of equipment used;6.1.6.7. date of the test(s) and date when the cores were taken from the test track.6.2. Documentation of vehicle noise tests conducted on the surfaceIn the document describing the vehicle noise test(s) it shall be stated whether all the requirements of this standard were fulfilled or not. Reference shall be made to a document according to point 6.1. describing the results which verify this._____________ANNEX VIIPart ARepealed Directive with list of its successive amendments(referred to in Article 14)Council Directive 92/23/EEC | (OJ L 129, 14.5.1992, p. 95) |Point XI.C.I.23 of Annex I to the 1994  Act of Accession | (OJ C 241, 29.8.1994, p. 193) |Directive 2001/43/EC of the European Parliament and of the Council | (OJ L 211, 4.8.2001, p. 25) |Commission Directive 2005/11/EC | (OJ L 46, 17.2.2005, p. 42) |Part BList of time-limits for transposition into national law and application(referred to in Article 14)Directive | Time-limit for transposition | Date of application |92/23/EEC | 30 June 1992 | 1 January 1993 |2001/43/EC | 3 August 2002 | 4 February 2003 |2005/11/EC | 31 December 2005 | 1 January 2006 |_____________ANNEX VIIICorrelation TableDirective 92/23/EEC | This Directive |Article 1, introductory sentence | Article 1, introductory sentence |Article 1, first indent | Article 1, point (a) |Article 1, second indent | Article 1, point (b) |Article 1, third indent | Article 1, point (c) |Article 1a | Article 2 |Article 2 | Article 3 |Article 3 | Article 4 |Article 4 | Article 5 |Article 5 | Article 6 |Article 6 | Article 7 |Article 7 | Article 8 |Article 8 | Article 9 |Article 9 | Article 10 |Article 10 | Article 11 |Article 10a | Article 12 |Article 11(1) | - |Article 11(2) | Article 13 |- | Article 14 |- | Article 15 |Article 12 | Article 16 |Annexes I-VI | Annexes I-VI |- | Annex VII |- | Annex VIII |____________[1] COM(87) 868 PV.[2] See Annex 3 to Part A of the Conclusions.[3] Entered in the legislative programme for […].[4] See Annex VII, Part A of this proposal.[5] OJ C [...], [...], p.
