EXPLANATORY MEMORANDUM 

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. 
On 1 April 1987 the Commission decided1 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. 

the  Edinburgh  European  Council 
The  Conclusions  of 
(December 1992) confirmed this2, stressing the importance of codification as it offers 
certainty as to the law applicable to a given matter at a given time. 

the  Presidency  of 

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. 

is 

this  proposal 

The  purpose  of 
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  fitting3.  The  new  Directive  will  supersede  the  various  acts 
incorporated in it4; 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. 

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.

Whereas: 

(1) 

Council  Directive  92/23/EEC  of  31  March  1992  relating  to  tyres  for  motor  vehicles

4.1. 

4.2. 

An EC type-approval number is to be assigned to each tyre type-approved. The same 
Member  State  must  not  assign  the  same  number  to  another  tyre  type.  In  particular, 
approval  numbers  assigned  pursuant  to  Annex II  and  EC type-approval  numbers 
assigned pursuant to Annex V must be different. 

EC TYPE-APPROVAL MARKING 

Any  tyre  conforming  to  a  type  in  respect  of  which  EC type-approval  has  been 
granted pursuant to this Directive must bear the relevant EC type-approval mark. 

The  EC  type-approval  mark  will  consist  of  a  rectangle  surrounding  the  lower  case 
letter ‘e’  followed  by  the  distinguishing  number  of  the  Member  State  which  has 
granted the type-approval as per Annex VII to Directive 2007/46/EC. The EC type-
approval  number  will  consist  of  the  EC type-approval  number  shown  on  the 
certificate  completed  for  the  type,  preceded  by  two  figures:  ‘00’ for  commercial 
vehicle tyres, ‘02’ for passenger car tyres. 

4.2.1.  The rectangle  forming the EC type-approval mark must have a minimum length of 
12 mm  and  a  minimum  height  of  8 mm.  Letter(s)  and  number(s)  must  be  at  least 
4 mm in height.

4.3. 

4.4. 

The  EC  type-approval  marks  and  numbers,  and  any  additional  marks  required  in 
Annex II, section 3., the latter for the type-approval pursuant to the requirements of 
Annex II, must be affixed as prescribed in that section. 

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: 

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. 

MODIFICATION OF A TYRE TYPE 

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. 

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. 

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. 

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. 

CONFORMITY OF PRODUCTION 

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. 

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

into  or  on  to  both  sidewalls,  and  at  least  on  one  side  on  the  lower  sidewall,  as 
follows: 

in the case of symmetrical tyres, all the markings referred to ⌦ in point 3.4 ⌫ must 
be located on both sidewalls except the markings referred to in points 3.1.9, 3.1.11 
and 3.3 which may be on one sidewall only; 

3.4.2. 

in  the  case  of  asymmetrical  tyres  all  the  markings  must  be  located  on  at  least  the 
outer sidewall.

Dimensional requirements 

6.1.1. 

Section width of a tyre 

6.1.1.1.  Except as provided by point 6.1.1.2, the section width is calculated by the following 

formula: 

S = S1 + K (A−A1), 

where: 

S 

S1 

= 

= 

A 

= 

the ‘section width’ expressed in mm29 and measured on the measuring rim; 

the ‘nominal section width’ in mm as shown on the sidewall of the tyre in 
the tyre-size designation as prescribed; 

the  width  (expressed  in  mm)  of  the  measuring  rim,  as  shown  by  the 
manufacturer  in  the  descriptive  note,  (see  point 6.11  of  Annex I, 
Appendix 1); 

A1  = 

the width (expressed in mm) of the theoretical rim; it is taken to equal S1 
multiplied  by  the  factor  x  as  specified  by  the  tyre  manufacturer  (see 
point 6.15 of Annex I, Appendix 1); and K is taken to equal 0,4. 

6.1.1.2.  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. 

29 

Equivalence factor from inches to mm is 25,4.

6.1.2.  Outer diameter of a tyre 

6.1.2.1.  Except as provided by point 6.1.2.2, the outer diameter of a tyre is calculated by the 

following formula: 

D = d + 0,02H 

where: 

—  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 dimensions 

The actual dimensions of tyres are measured as prescribed in Appendix 6. 

6.1.4.  Tyre section width: specification of tolerance 

6.1.4.1.  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 %; and 

6.1.4.2.3. 

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 tolerance 

The 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) 

EN 

31 

   EN 

 
 
 
 
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 tyres

⌦ point 6.1.5 ⌫ may be exceeded by 1 %. 

6.2. 

Load/speed test requirement 

6.2.1.  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 indicators 

6.3.1. 

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.  The  tread-wear  indicators  must  give  visual  warning  when  the  depth  of  the 
corresponding tread grooves has been reduced to 1,6 mm with a tolerance of + 0,6/-
 0 mm.

1.1. 

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):

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. 

The pressure is readjusted to that specified in point 1.2. 

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. 

The  outer  diameter  is  determined  by  measuring  the  maximum  circumference  and 
dividing the figure so obtained by π (3,1416). 

PART B: COMMERCIAL VEHICLE TYRES 

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. 

The tyre fitted on its rim is conditioned to the ambient temperature of the laboratory 
for at least 24 hours. 

The pressure is readjusted to the value specified in section 1. 

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

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). 

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. 

2.1. 

CARRYING OUT THE TEST 

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; 

30 

In  the  case  of  passenger  car  tyres  intended  for  vehicles  designed  for  a  maximum  speed  greater  than 
240 km/h (Z rated tyres), until uniform test procedures have been agreed the manufacturer of the tyre 
must satisfy the technical service that his test procedure and results are acceptable.

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. 

2.4. 

2.5. 

Throughout the test the tyre pressure must not be corrected and the test load must be 
kept constant. 
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. 

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.

EQUIVALENT TEST METHODS 

If  a  method  other  than  that  described  in  section 2  is  used,  its  equivalence  must  be 
demonstrated.

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. 

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. 

31 

In  the  case  of  commercial  vehicle  tyres  intended  for  vehicles  designed  for  a  maximum  speed  greater 
than 150 km/h, until uniform test procedures have been agreed the manufacturer of the tyre must satisfy 
the technical service that his test procedure and results are acceptable.

TEST PROCEDURE 

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. 

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. 

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. 
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.

1.4. 

APPLICATION  FOR  THE  (cid:206)1 EC  TYPE-APPROVAL   OF  A  VEHICLE 
TYPE 

The application for (cid:206)1 EC type-approval  of a vehicle type with regard to its tyres 
is submitted by the vehicle manufacturer or by his authorised representative. 

It is accompanied, in triplicate, by a description of the vehicle type and of its tyres in 
terms  of  their  tyre-size  designation,  speed  category  and  load-capacity  index, 
including any temporary-use spare unit(s), with which it may be fitted as described in 
the information document in Appendix 1. 

A vehicle representative of the vehicle type to be approved must be submitted to the 
technical service responsible for conducting the approval tests. 

The  vehicle  manufacturer  or  his  representative  may  apply  for  the  (cid:206)1 EC type-
approval   to  be  extended  to  include  tyres  of  additional  tyre-size  designations, 
speed categories or load-capacity indices or additional temporary-use spare unit(s). 

2. 

(cid:206)1 EC TYPE-APPROVAL  OF A VEHICLE 

2.1.  (cid:206)1 EC  type-approval  is granted and  an (cid:206)1 EC type-approval  number issued 
in respect of any vehicle type submitted in accordance with section 1 which satisfied 
the requirements of this Directive. 

2.2. 

2.3. 

3. 

3.1. 

Notice  of  approval  or  of  extension  or  of  refusal  of  approval  of  a  vehicle  type 
pursuant to this Directive is communicated to the Member States by means of a form 
conforming to the model in Appendix 2. 

An approval number is assigned to each vehicle type approved. The same Member 
State must not assign the same number to another vehicle type. 

MODIFICATION OF VEHICLE TYPE 

Every modification of a vehicle type must be notified to the approval authority which 
approved it. That approval authority may then either: 

3.1.1. 

consider  that  the  modifications  made  are  unlikely  to  have  an  appreciable  adverse 
effect and that in any case the vehicle still meets the requirements; or 

3.1.2. 

refuse to approve the modification. 

3.2. 

4. 

4.1. 

4.2. 

Confirmation  or  refusal  of  approval,  specifying  the  alterations,  is  communicated  to 
the other Member States by the procedure specified in point 2.2. 

CONFORMITY OF PRODUCTION 

Every  production  vehicle  to  which  this  Directive  applies  must  be  so  manufactured 
that it conforms to all of the relevant requirements of this Directive. 

In order to verify that the requirements of point 4.1 are met, suitable controls of the 
production must be carried out. 

EN 

87 

   EN 

4.3. 

The holder of the approval must in particular ensure the existence of procedures for 
effectively checking on compatibility between the characteristics of the vehicle and 
the  characteristics  of  the  tyres  fitted  as  laid  down  within  the  framework  of  this 
Directive. 

4.4. 

The approval authority which has granted type-approval may at any time verify the 
conformity control methods applicable to each production unit. 

4.4.1. 

In every inspection, the test books and productions survey records must be presented 
to the visiting inspector. 

4.5. 

The normal frequency of inspections authorised by the approval authority is one per 
year. In the case where negative results are recorded during one of these visits, the 
approval authority must ensure that all necessary  steps are taken to re-establish the 
conformity of production as rapidly as possible. 

5. 

PRODUCTION DEFINITIVELY DISCONTINUED 

If  the  holder  of  an  approval  completely  ceases  to  manufacture  a  type  of  vehicle 
approved  in  accordance  with  this  Directive,  he  must  so  inform  the  authority  which 
granted the approval. Upon receiving the relevant communication that authority must 
inform  thereof  the  other  approval  authorities  by  means  of  a  copy  of  the  approval 
form  bearing  at  the  end,  in  large  letters,  the  signed  and  dated  annotation 
‘PRODUCTION DISCONTINUED’.

2.7.1. 

DEFINITIONS 

FOR THE PURPOSE OF THIS DIRECTIVE: 

‘approval of a vehicle’ means the approval of a vehicle type with regard to its tyres, 
including temporary-use spare tyres; 

‘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: 

‘wheel’ means a complete wheel consisting of a rim and a wheel disc; 

‘temporary-use spare wheel’ means a wheel different from one of the normal wheels 
on the vehicle type; 

‘unit’ means an assembly of a wheel and tyre; 

‘normal unit’ means a unit which is capable of being fitted to the vehicle for normal 
operation; 

‘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: 

‘normal spare unit’, which is a unit that conforms to the normal unit of the vehicle 
type; 

‘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 1 

a 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 2 

a 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 3 

a  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; 

EN 

92 

   EN 

 
 
 
2.7.1.4.  category 4 

2.8. 

2.9. 

a 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; 

‘maximum mass’ means the maximum value stated by the vehicle manufacturer to be 
technically permissible for the vehicle; 

‘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 TYRES 

3.1. 

General 

(cid:208) 2001/43/EC Art. 1 pt. 5 and 
Annex pt. 7 

3.1.1.  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. 

(cid:208) 92/23/EEC 

3.2. 

Tyre fitment 

3.2.1.  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. 

EN 

93 

   EN 

 
 
 
3.3. 

Load capacity 

3.3.1.  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 capacity 

3.4.1.  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. 

Spare tyre 

3.5.1. 

In the case where a vehicle is provided with a spare wheel its tyre must be: 

3.5.1.1.  the same type as one of the tyres fitted to or approved for the vehicle, or 

3.5.1.2.  a temporary-use spare tyre of a type suitable for use on the vehicle, in any position. 
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 

EN 

94 

   EN 

 
 
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 cases 

3.7.1. 

3.7.2. 

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. 

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, 

EN 

95 

   EN 

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 units 

3.8.1.  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

TEST METHOD FOR TYRE-ROAD SOUND LEVELS, COAST-BY METHOD 

Appendix 1 

0. 

INTRODUCTION 

The  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 INSTRUMENTS 

1.1. 

Acoustic measurements 

The 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. 

(cid:208) 2001/43/EC Art. 1 pt. 5 and 
Annex pt. 8 (adapted) 

1.1.1.  Calibration 

At  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. 

(cid:208) 2001/43/EC Art. 1 pt. 5 and 
Annex pt. 8 

1.1.2.  Compliance with requirements 

The  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. 

EN 

100 

   EN 

 
 
 
 
 
 
 
 
1.1.3.  Positioning of the microphone 

The  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 measurements 

The 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 measurements 

Measurements  of  air  as  well  as  test  surface  temperature  are  mandatory.  The 
temperature measuring devices shall be accurate within ± 1 oC. 

1.3.1.  Air temperature 

The  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 temperature 

The  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 measurement 

The 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 MEASUREMENT 

2.1. 

Test site 

The 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 

EN 

101 

   EN 

 
 
 
 
 
 
 
 
 
 
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 conditions 

Measurements  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 noise 

The  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 requirements 

2.4.1.  General 

The test vehicle shall be a motor vehicle and be fitted with four single tyres on just 
two axles. 

2.4.2.  Vehicle load 

The vehicle must be loaded such as to comply with the test tyre loads as specified in 
point 2.5.2. . 

2.4.3.  Wheelbase 

The 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 measurements 

To 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. 

EN 

102 

   EN 

 
 
 
 
 
 
 
 
 
 
(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. 

Tyres 

2.5.1.  General 

Four 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 loads 

The  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 pressure 

Each tyre fitted on the test vehicle shall have a test pressure Pt not  higher than  the 
reference pressure Pr and within the interval: 

where Pr is the pressure corresponding to the pressure index marked on the sidewall. 

EN 

103 

   EN 

 
 
 
 
 
 
 
 
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 testing 

The  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 TESTING 

3.1. 

General conditions 

For 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 measurements 

The  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 speeds 

The 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 RESULTS 

The measurement shall be invalid if an abnormal discrepancy between the maximum 
value and the other values is recorded. 

4.1. 

Determination of test result 

Reference 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 measurements 

The (not temperature corrected) tyre-road noise level LR in dB(A) is determined by a 
regression analysis according to: 

where: 

 is the mean value of the noise levels Li, measured in dB(A): 

n is the measurement number (n ≥ 16), 

 is the mean value of logarithms of speeds vi:

Temperature correction 

(cid:208) 2001/43/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: 

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.

(cid:208) 2001/43/EC Art. 1 pt. 5 and 
Annex pt. 8 

If 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. 

4.5. 

In  order  to  take  account  of  any  measuring  instrument  inaccuracies,  the  results 
according to point 4.3. shall be reduced by 1 dB(A). 

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.

ANNEX VI 

SPECIFICATIONS FOR THE TEST SITE 

1. 

INTRODUCTION 

This  Annex  describes  the  specifications  relating  to  the  physical  characteristics  and 
the  laying  of  the  test  track.  These  specifications  based  on  a  special  standard32 
describe  the  required  physical  characteristics  as  well  as  the  test  methods  for  these 
characteristics. 

2. 

REQUIRED CHARACTERISTICS OF THE SURFACE 

A  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 content 

The  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 coefficient 

If 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 depth 

The texture depth (TD) measured according to the volumetric method (see point 4.3. 
) shall be: 

2.4. 

Homogeneity of the surface 

TD ≥ 0,4 mm 

Every  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 

32 

ISO 10844:1994 If a different test surface is defined by ISO, in the future, the reference standard will be

unevenness causing bumps may also occur. 

2.5. 

Period of testing 

In 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.

TEST SURFACE DESIGN 

3.1. 

Area 

When  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.

3.2. 

Design and preparation of the surface 

3.2.1.  Basic design requirements 

The 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 guidelines 

As  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: 

EN

10 mm for the lower tolerance curve

Figure 2: 

Grading curve of the aggregate in the asphaltic mix with tolerances 

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 
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.

TEST METHOD 

4.1.  Measurement of the residual voids content 

For 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. 

EN 

113 

   EN 

 
 
 
 
 
 
 
 
 
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 coefficient 

The  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 measurement 

For  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 MAINTENANCE 

5.1. 

Age influence 

In  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 surface 

Loose  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 area 

If  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 

EN 

114 

   EN 

 
 
 
 
 
 
 
 
 
 
test  area  outside  the  strip  met  the  requirement  of  residual  voids  content  or  sound 
absorption when it was measured. 

6.
