Joint text of the Conciliation Committee of 13 December 1994.() OJ No L 42, 23. 2. 1970, p. 1, as last amended by Directive 92/53/EEC (OJ No L 225, 10. 8. 1992, p. 1).ANNEX I REQUIREMENTS CONCERNING THE METHOD OF MEASURING THE MAXIMUM DESIGN SPEED 1. Requirements.1.1. The maximum design speed of the vehicle is measured in accordance with the requirements set out below.2. Preparation of the vehicle.2.1. The vehicle must be clean and only those accessories needed to enable the vehicle to undergo the test must be in operation.2.2. The fuel-supply and the ignition settings, the viscosity of the lubricants for the mechanical parts in motion, and the tyre pressures, must be as required by the manufacturer.2.3. The engine, transmission and tires must have been properly run in in accordance with the manufacturer's requirements.2.4. Before the test all parts of the vehicle must be in a thermally stable state, at their normal operating temperature.2.5. The vehicle must be submitted at its mass in running order.2.6. The distribution of the loadings among the wheels must be as intended by the manufacturer.3. Driver.3.1. Uncabbed vehicles3.1.1. The driver must have a mass of 75 kg ± 5 kg and be 1,75 m ± 0,05 m tall. However, in the case of mopeds these tolerances are reduced to ± 2 kg and ± 0,02 m respectively.3.1.2. The driver must wear an adjusted one-piece suit or an equivalent item of clothing.3.1.3. He must be seated on the driver's seat with his feet on the pedals or footrest and his arms normally extended. Where vehicles achieve a maximum speed of more than 120 km/h when their rider is in a seated position that rider must be equipped and positioned as recommended by the manufacturer. However, that position must enable the driver continuously to control the vehicle during the test. The driving position must be the same throughout the test and a description of that position given in the test report or replaced by photographs.3.2. Cabbed vehicles.3.2.1. The driver must have a mass of 75 kg ± 5 kg. However, in the case of mopeds, this tolerance is reduced to ± 2 kg.4. Characteristics of the test track.4.1. The tests must be carried out on a road:4.1.1. which allows the maximum speed to be maintained along a measurement base as defined in 4.2. The acceleration track preceding the measuring base must be of the same type (surface and longitudinal profile) and be sufficiently long in order to enable the vehicle's maximum speed to be reached;4.1.2. that is clean, smooth, dry, asphalted or surfaced in an equivalent manner;4.1.3. having a longitudinal gradient of not more than 1 % and a degree of banking of not more than 3 %. The variation in altitude between any two points on the test base must not exceed 1 m.4.2. The possible configurations for the measuring base are illustrated in 4.2.1, 4.2.2 and 4.2.3.4.2.1. Type 1>REFERENCE TO A FILM>4.2.2. Type 2>REFERENCE TO A FILM>4.2.3. Type 3>REFERENCE TO A FILM>4.2.3.1. The two measuring bases L must be equal in length and virtually parallel to each other.4.2.3.2. If both measuring bases are curvilinear in shape despite the requirements of 4.1.3, the effects of centrifugal force must be compensated for by the cross-section of the bends.4.2.3.3. Instead of the two bases L (see 4.2.3.1), the measuring base may coincide with the overall length of the annual test track. In this case the minimum radius of the bends must be 200 m and the effects of centrifugal force compensated for by the cross-section of the bends.4.3. Length L of the measuring base must be selected in conjunction with the accuracy of the equipment and the methods used to measure testing time t in such a way that the value for actual speed can be plotted to within +/- 1 %. If the measuring equipment is of the manual type, length L of the measuring base must not be less than 500 m. If a type 2 measuring base has been selected it will be necessary to use electronic measuring equipment in order to determine time t.5. ATMOSPHERIC CONDITIONSAtmospheric pressure: 97 ± 6 kPa.Temperature: between 278 and 308 K.Relative humidity: 30 to 90 %.Maximum windspeed: 3 m/s.6. TEST PROCEDURE6.1. The gear ratio used during the test must be that enabling the vehicle to reach its maximum speed on level ground. The throttle control must be kept fully open and the enrichment devices must be inoperative.6.2. Drivers of uncabbed vehicles must maintain their driving position as defined in 3.1.3.6.3. The vehicle must arrive at the measuring base at a constant speed. Type 1 and type 2 bases must be travelled along in both directions in succession.6.3.1. Testing in a single direction may be accepted on a type 2 measuring base if, owing to the characteristics of the circuit, it is not possible to reach the maximum speed of the vehicle in both directions. In this case:6.3.1.1. the test run must be repeated five times in immediate succession;6.3.1.2. the speed of the axial wind component must not exceed 1 m/s.6.4. Both bases L on a type 3 measuring base must be travelled along consecutively in a single direction, without interruption.6.4.1. If the measuring base coincides with the total length of the circuit, it must be travelled along in a single direction at least twice. The difference between the extremes of the time measurements must not exceed 3 %.6.5. The fuel and lubricant must be those recommended by the manufacturer.6.6. The total time t needed to travel along the measuring base in both directions must be determined to an accuracy of 0,7 %.6.7. The determination of average speed.Average speed V (km/h) for the test is determined as follows:6.7.1. Type 1 and type 2 measuring baseV = >NUM>3,6 × 2 L >DEN>t = >NUM>7,2 L >DEN>twhere:L = length of measuring base (m)t = time (s) taken to travel along measuring base L (m).6.7.2. Type 2 measuring base, travelled along in a single directionV = Vawhere:Va = speed measured for each test run (km/h) = >NUM>3,6 L >DEN>twhere t = time (s) taken to travel along measuring base L (m).6.7.3. Type 3 measuring base.6.7.3.1. Measuring base consisting of two parts L (see 4.2.3.1)V = >NUM>3,6 × 2 L >DEN>t = >NUM>7,2 L >DEN>twhere:L = length of measuring base (m)t = total time (s) needed to travel along both measuring bases L (m).6.7.3.2. Measuring base coinciding with the total length of the annular test track (see 4.2.3.3)V = Va  . kwhere:Va = speed measured (km/h) = >NUM>3,6 L >DEN>twhere:L = length of trajectory actually followed on the annular speed-test track (m)t = time (s) needed to complete a full lapt = >NUM>1 >DEN>n  . Ói=1n  . tiwhere:n = number of lapsti = time (s) needed to complete each lapk = correction factor (1,00 &le; 1,05); this factor is specific to the annular test track used and is determined experimentally in line with Appendix 1.6.8. The average speed must be measured at least twice in succession.7. MAXIMUM SPEEDThe maximum speed of the vehicle is expressed in kilometres per hour by the figure corresponding to the closest whole number to the arithmetical mean of the values for the speeds measured during the two consecutive tests, which must not diverge by more than 3 %. When this arithmetical mean lies exactly between two whole members it is rounded up to the next highest number.8. MAXIMUM SPEED MEASUREMENT TOLERANCES8.1. The maximum speed as determined by the testing body may differ from the values specified by the manufacturer by ± 5 %.8.2. During a production conformity check the maximum speed may differ by ± 5 % from the value determined during the component type-approval test. That value becomes +/- 10 % in the case of mopeds the maximum design speed of which is &le; 30 km/h.Appendix 1 Procedure for defining the correction coefficient for the annular test track1. Coefficient k relating to the annular test track must be plotted up to the maximum permitted speed.2. Coefficient k must be plotted for several speeds in such a way that the difference between two consecutive speeds will not be more than 30 km/h.3. For each speed selected the test must be carried out in line with the requirements of this Directive, in two possible ways:3.1. Speed measured in a straight line Vd.3.2. Speed measured on the annular test track Va.4. For each speed measured values Va and Vd are entered on a diagram (figure 1) and the successive points linked by means of a segment of a straight line.>REFERENCE TO A FILM>Figure 15. The coefficient k is given by the following formula for each speed measured:k = >NUM>Vd >DEN>VaAppendix 2 Information document concerning the essential characteristics of the vehicle type that affect its maximum design speed >START OF GRAPHIC>(to be added to the component type-approval application where this is lodged separately from the vehicle type-approval application)Reference number (supplied by the applicant): ...The application for component type-approval in respect of the maximum design speed of a type of two or three-wheel motor vehicle must contain the information set out in Annex II to Directive 92/61/EEC, Part A, in the following sections:0.10.20.4 to 0.62.1 to 2.2.13.0 to 3.1.14.1 to 4.65.25.2.2>END OF GRAPHIC>Appendix 3 Name of Administration Component type-approval certificate in respect of the maximum design speed of a type of two or three-wheel motor vehicle >START OF GRAPHIC>MODELReport No ... by technical service ..., date ...Component type-approval No:...Extension No:...1.

Setting conditionsThe conditions applying to settings during the tests to determine maximum torque and maximum net power are set out in Table 2.>TABLE>3.3. Test conditions.3.3.1. The tests intended to determine maximum torque and maximum net power must be carried out at full throttle, with the engine equipped as specified in Table 1.3.3.2. The measurements must be carried out under normal, stable operating conditions and the air supply to the engine must be adequate. The engine must have been run in under the conditions recommended by the manufacturer. The combustion chambers may contain deposits, but in limited quantities.The test conditions such as the temperature of the induction air must be selected as closely as possible to the reference conditions (see 4.2) in order to reduce the correction factor.3.3.3. The temperature of the engine induction air (ambient air) must be measured at the most 0,15 m upstream of the air filter inlet or, if there is no filter, 0,15 m from the inlet air trumpet. The thermometer or thermocouple must be protected against heat radiation and be placed directly in the airstream. It must also be protected against vaporized fuel. An adequate number of positions must be used in order to yield a representative average inlet temperature.3.3.4. No measurement is taken until the torque, rate of rotation and temperatures have remained substantially constant for at least 30 seconds.3.3.5. Once a rate of rotation has been selected to the measurements its value must not vary by more than ± 2 %.3.3.6. The brake load and the temperature of the induction air must be recorded simultaneously and the value obtained must be the average of the two stabilized records taken in succession, which must not differ by more than 2 % as regards the brake load.3.3.7. Where an automatically triggered device is used to measure rotational speed and consumption the measurement must last for at least 10 s and if the measuring device is manually controlled that period must be at least 20 s.3.3.8. The temperature of the liquid coolant recorded at the engine outlet must be maintained at ± 5 K of the upper thermostat setting temperature specified by the manufacturer. If the manufacturer does not indicate any values the temperature is 353 K ± 5 K.In the case of air-cooled engines the temperature at a point specified by the manufacturer must be maintained at + 0/- 20 K of the maximum temperature intended by the manufacturer under the reference conditions.3.3.9.

FuelThe fuel must be of a commercially available type and receive no further anti-smoke additive ().3.4. Test sequenceThe measurements must be carried out at a sufficient number of rotational speeds to enable the power curve to be defined correctly between the lowest and highest speeds recommended by the manufacturer. That range of speeds must include the rotational speed at which the engine delivers its maximum torque and maximum power. The average of at least two stabilized measurements must be determined for each speed.3.5. The data to be recorded are those set out in Sub-Appendix 1.4. POWER AND TORQUE CORRECTION FACTORS4.1.

Reference atmospheric conditions4.2.1. Temperature25 °C (298 K)4.2.2. Dry reference pressure (Pso):99 kPa (990 mbar)4.3. Limits to the use of the correction formulaThe correction formula applies only if the correction factor lies between 0,93 and 1,07.If these accepted values are exceeded, the corrected value obtained must be stated and the test conditions (temperature and pressure) specified exactly in the test report.Note:Tests carried out in temperature-controlled rooms where it is possible to vary the atmospheric conditions are permitted.4.4. Determination of the correction factor á1Within the limits defined in 4.3 the correction factor is obtained via the following formula:á1 = (>NUM>99 >DEN>Ps)1,2 . (>NUM>T >DEN>298)0,6where:T = the absolute temperature in Kelvins of the engine induction airP = the total atmospheric pressure, in kilopascalsPV = the water vapour pressure, in kilopascalsPS = P - PVThis formula applies to the torque and power read-off at the brake without taking account of the mechanical efficiency of the engine.4.5. Determination of the correction factor for mechanical efficiency of the transmission á2Determination of the factor á2:- where the measuring point is the crankshaft output side this factor must be 1,- where the measuring point is not the output side of the crankshaft this factor is calculated via the formula:á2 = >NUM>1 >DEN>ntwhere nt is the efficiency of the transmission located between the crankshaft and measuring point.This transmission efficiency nt is determined via the product (multiplication) of efficiency nj of each of the components of the transmission:nt = n1 × n2 ...... × njEfficiency nj of each of the components of the transmission is shown in the following table:>TABLE>5.

Accessories to be fittedDuring the test the accessories needed for operation of the engine in the application under consideration (as referred to in Table 1) must be able to be located on the test bench as far as possible in the positions that they would occupy for the application under consideration.3.1.2. Accessories to be removedCertain accessories which are necessary only for the operation of the vehicle itself, and which may be mounted on the engine, must be removed for the test.Where accessories cannot be removed the power absorbed by them under no load may be determined and added to the engine power measured.>TABLE>3.2. Setting conditionsThe setting conditions for the test to determine maximum torque and maximum net power are set out in Table 2.>TABLE>3.3. Test conditions.3.3.1. The maximum-torque and net-power tests must be conducted at full throttle, the engine being equipped as specified in Table 1.3.3.2. The measurements must be carried out under normal, stabilized operating conditions with an adequate fresh-air supply to the engine. The engine must have been run in in accordance with the manufacturer's recommendations. Combustion chambers may contain deposits, but in limited quantities.Test conditions such as air inlet temperature must be selected as near to reference conditions (see 4.2) as possible in order to minimize the magnitude of the correction factor.Where the cooling system on the test bench meets the minimum conditions for proper installation but nevertheless does not enable adequate cooling conditions to be reproduced and thus the measurements to be carried out in normal, stable operating conditions, the method described in Sub-Appendix 1 may be used.The minimum conditions which must be fulfilled by the test installation and the scope for conducting the tests in accordance with Sub-Appendix 1 are defined below:V1 is the maximum speed of the vehicle;V2 is the maximum velocity of the cooling air flow at the fan delivery side;Ø is the cross-section of the cooling air flow.If V2 &ge; V1 and Ø &ge; 0,25 m² the minimum conditions are fulfilled. If it is not possible to stabilize the operating conditions the method described in Sub-Appendix 1 applies.If V2 &lt; V1 and/or Ø &lt; 0,25 m²:(a) if it is possible to stabilize the operating conditions the method described in 3.3 is applied;(b) if it is not possible to stabilize the operating conditions:(i) if V2 &ge; 120 km/h and Ø &ge; 0,25 m², the installation fulfils the minimum conditions and the method described in Appendix 1 may be applied;(ii) if V2 &lt; 120 km/h and/or Ø &lt; 0,25 m², the installation does not fulfil the minimum conditions and the test equipment cooling system must be improved.However, in this case, the test may be carried out by means of the method described in Sub-Appendix 1, subject to approval by the manufacturer and the administration.3.3.3. The temperature of the (ambient) inlet air to the engine must be measured at no more than 0,15 m upstream from the point of entry into the air cleaner or, if no air cleaner is used, within 0,15 m of the air-inlet trumpet. The thermometer or thermocouple must be shielded from radiant heat and be placed directly in the airstream. It must also be shielded from fuel spray-back.A sufficient number of locations must be used to give a representative average inlet temperature.3.3.4. No data must be taken until torque, speed and temperature have remained substantially constant for at least 30 s.3.3.5.

Engines must have been run in under the conditions recommended by their manufacturer. The combustion chambers of spark-ignition engines may contain deposits, but in limited quantities.The test conditions, such as the temperature of the induction air, must be selected so as to be as close as possible to the reference conditions (see 4.2.1) in order to reduce the magnitude of the correction factor.1.3. The temperature of the air ingested into the engine must be measured at a maximum distance of 0,15 m from the air filter inlet or, if there is no filter, 0,15 m from the air inlet trumpet. The thermometer or thermocouple must be protected against radiant heat and placed directly in the air stream. It must also be shielded from fuel spray-back. A sufficient number of locations must be used to give a representative average inlet temperature.1.4. The engine speed during a measurement run must not deviate from the selected speed while readings are taken by more than ± 1 %.1.5.

Brakeload, fuel consumption and inlet air-temperature readings must be taken simultaneously, the reading adopted for measurement purposes is the average of two stabilized values differing by less than 2 % for brakeload and fuel consumption.1.7. The fuel consumption readings begin when it is certain that the engine has reached a specific speed.Where an automatically triggered device is used to measure rotational speed and consumption the measurement must last for at least 10 seconds and if the measuring device is manually controlled for at least 20 seconds.1.8. Where the engine is liquid cooled the temperature of the coolant at the outlet from the engine must be kept within ± 5 K of the upper thermostatically controlled temperature specified by the manufacturer.

Determination of correction factors áa and ád ()The power correction factor (ád) for compression-ignition engines at constant fuel rate is obtained by applying the formula:ád = (fa) fmwhere:fa = the atmospheric factorfm = the characteristic parameter for each type of engine and adjustment.4.4.1. Atmospheric factor faThis factor indicates the effects of environmental conditions (pressure, temperature and humidity) on the air drawn in by the engine.
