intended for the transportation of persons and goods and not intended for use on public roads - Safety requirements”, the secretariat of which is held by AFNOR This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by December 2012, and conflicting national standards shall be withdrawn at the latest by December 2012 Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights other than those identified above CEN [and/or] CENELEC shall not be held responsible for identifying any or all such patent rights This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive(s) For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this document According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom BS EN 16029:2012 EN 16029:2012 (E) Introduction This European Standard has been prepared to be a harmonised standard to provide a means of conforming to the essential safety requirements of the Machinery Directive and associated EFTA regulations This standard covers single-track two-wheel motor vehicles not intended to be used on public roads These vehicles are ridden by both adults and children Vehicles within the scope of this standard and intended to be used by children are specifically designed and manufactured for young users Specific requirements are given in this standard for these vehicles This standard defines specific requirements for the marking of small vehicles intended for use only by adults which, because of their size, can be ridden by children The importance of providing vehicles which are safe when used by children is recognised The safety of children is dependent on the design of the vehicle and the information provided with it However, no matter how good the design and information is, safe use will always be reliant on suitable training, experience, maturity of the rider, assessment of ability and supervision by carers, especially for novice riders To reflect the importance of child safety, further research will be started immediately after publication of the standard to enable the standard to be revised as soon as additional design measures and guidance have been established The structure of safety standards in the field of machinery is as follows: a) Type-A standards (basis standards) give basic concepts, principles for design, and general aspects that can be applied to machinery b) Type-B standards (generic safety standards) deal with one or more safety aspect(s) or one or more type(s) of safeguards that can be used across a wide range of machinery: c) 1) type-B1 standards on particular safety aspects (e.g safety distances, surface temperature, noise); 2) type-B2 standards on safeguards (e.g two-hand controls, interlocking devices, pressuresensitive devices, guards) Type-C standards (machinery safety standards) deal with detailed safety requirements for a particular machine or group of machines This document is a type C standard as stated in EN ISO 12100 When provisions of this type C standard are different from those which are stated in type A or B standards, the provisions of this type C standard take precedence over the provisions of the other standards, for machines that have been designed and built according to the provisions of this type C standard The machinery concerned and the extent to which hazards, hazardous situations and hazardous events are covered are indicated in the scope of this document BS EN 16029:2012 EN 16029:2012 (E) Scope This European Standard specifies the safety requirements and the test methods for single-track two-wheel motor vehicles, driven by a rider sitting astride This European Standard deals with all significant hazards, hazardous situations and events relevant to single-track two-wheel motor vehicles propelled by a spark ignited internal combustion engine (hereinafter referred to as "vehicles"), when they are used as intended and under the conditions of misuse which are reasonably foreseeable by the manufacturer The vehicles covered by this European Standard are not intended to be used on public roads The vehicles covered by this European Standard are intended only for the rider and not for passengers This European Standard does not cover vehicles propelled with gaseous fuels This European Standard specifies the appropriate measures to eliminate or reduce the risks arising from the significant hazards, hazardous situations and events (see Clause 4) during commissioning, operation and maintenance of the vehicles when carried out in accordance with the specifications as intended by the manufacturer This European Standard is not applicable to vehicles which are manufactured before the date of

the mass in running order of the vehicle, expressed in kg 57 BS EN 16029:2012 EN 16029:2012 (E) Annex A (normative) Noise test A.1 General The global noise emitted by the vehicle included in this standard considers only the static noise of the vehicle The noise emission values determined according to this noise test code may underestimate the actual emission during normal use of the vehicle, in particular when the vehicle is in motion A.2 Operating and mounting conditions The test vehicle shall be new and be fitted with any attachment affecting noise properties as well as with those recommended by the manufacturer Whenever the vehicle attachments are optional, testing is carried out with those that give the least favourable noise results Before beginning the test, the vehicle shall be brought to the normal operating temperature The test is conducted with the fuel tank at over 50 % of capacity The vehicle shall be in a stationary position in a stable condition of support, using the devices fitted (prop, stand or similar) in line with the manufacturer's instructions for safe usage The riders shall not position themselves directly between any microphone and the vehicle The tests shall be performed with the engine running under the following conditions and with the rider in riding position gearbox in neutral gear; if it is impossible to disconnect the transmission, the drive wheel shall not touch the ground; and the engine speed shall be held steady at the following value: S/2 ± % (with a minimum value of -1 000 ), where S is the speed corresponding to the maximum output of the engine (indicate standard used): (kW) at r/min A.3 Noise measurements The time-averaged A-weighted sound pressure level is determined using the following equation: Lp , Aeq,T T p A2 (t ) = 10 lg ∫ dt , in dB T p0 (A.1) where 58 T is the measurement period, i.e the period of the time the vehicle is operated during the test, in s; pA(t) is the instantaneous A-weighted sound pressure of the sound signal, in µPa; p0 is the reference sound pressure (20 µPa) BS EN 16029:2012 EN 16029:2012 (E) A.4 Test environment The acoustic environment shall include a test surface which consists of a hard reflecting plane, such as concrete or sealed asphalt, and with no sound-reflecting obstacles within a distance from the source equal to 25 m Within these conditions, it may be assumed that the environmental correction K2 is less than or equal to 0,5 dB It is therefore, negligible and it is disregarded At each measurement position, background noise shall be at least 10 dB lower than the noise emitted by the vehicle tested In addition, the following shall be considered: Measurements shall not be carried out when precipitation is falling or when the ground surface is covered with snow, water or hail The admissible ambient temperature during measurement is from -10 ºC to 35 ºC No vehicle auditory warning device shall be activated during the test, such as a horn The measurements shall not be considered valid for wind speeds above m/s For wind speeds greater than m/s an anti-wind screen for the microphones shall be used, and calibration corrections should be considered appropriate by the use of such screens Humidity, air temperature, barometric pressure, the vibratory state and the intensity of the magnetic fields shall remain within the limits specified by the test equipment manufacturer A.5 Determination of A-weighted emission sound pressure level at rider’s ear A.5.1 Microphone position The microphone shall be supported independently from the equipment being tested Two measurement positions shall be used: the microphone shall be located 760 mm above the laden seat, and 250 mm to the right and to the left of the centreline of the rider's position, defined by the manufacturer The instruments to be used during the test and the calibration requirements are specified in EN ISO 11201 A.5.2 Measurements The measurement time for each reading at each measurement position shall be in the range of s to s This measurement is realised in the range of s to s because it is not possible to maintain the engine speed at constant value for a longer period To compensate for that, the following procedure shall be used Measurements shall be repeated and only those measurement results that not differ by more than dB(A) in three consecutive tests shall be used Thus, the average of the three measurements for each position shall be taken Finally, the higher value of the results for the two positions constitutes the A-weighted emission sound pressure level at rider's ear, which shall be rounded to the nearest whole number (< 0,5, use lower number; ≥ 0,5, use higher number) In the absence of specific knowledge of uncertainty for vehicles, the uncertainty shall be considered equal to KA = dB The actual uncertainty may be larger if the noise emission of the vehicle is unstable A.6 Determining if further measurements are necessary If the test result (A-weighted emission sound pressure level) at rider’s ear is 80 dB(A) or less than 80 dB(A), the noise test shall be finished 59 BS EN 16029:2012 EN 16029:2012 (E) If the test result at rider’s ear is higher than 80 dB(A), the vehicle shall be tested according to A.7 and the sound power shall be calculated according to A.8 A.7 Determining the time averaged A-weighted sound pressure levels A.7.1 General The instruments to be used during the test and the calibration requirements are specified in EN ISO 3744 A.7.2 Size of the measurement surface Measurement surface is a hemisphere of radius r, where r is function of the distance between back and front of the vehicle The radius shall be: m, when length between back and front is less than 1,5 m; 10 m when length between back and front is equal or greater than 1,5 m A.7.3 Microphone positions on the measurement surface of the hemisphere Six measurement positions shall be used in the test, corresponding to the microphone positions 1, 2, 3, 4, and 6, in accordance with the distribution and co-ordinates defined in Figure A.1 and in Table A.1 Figure A.1 — Microphone positions on the hemisphere Table A.1 — Co-ordinates of the microphone positions in the hemisphere 60 Microphone Nº x/r y/r z(m) 0,7 0,7 1,5 -0,7 0,7 1,5 -0,7 -0,7 1,5 0,7 -0,7 1,5 -0,27 0,65 0,71r 0,27 -0,65 0,71r BS EN 16029:2012 EN 16029:2012 (E) NOTE With these microphone positions, no significant differences have been noted in comparison with measurements performed with 12 microphone positions according to EN ISO 3744 A.7.4 Measurements The centre of the hemisphere shall coincide with the geometric centre of the vehicle The segment joining the front and rear ends of the vehicle shall be aligned with the x-axle defined in Figure A.1 The measurement time for each reading at each measurement position shall be in the range of s to s This measurement is realised in the range of s to s because it is not possible to maintain the engine speed at constant value for a longer period To compensate for that, the following procedure shall be used A minimum of three series of measurements at all microphone positions shall be carried out In order to meet the next requirement, additional series of measurements may be necessary: Three values of the sound power levels shall be calculated separately from the three series of values obtained for each microphone position, according to A.8 If two of the three values of the sound power thus obtained not differ by more than dB, no more measurements are necessary If this is not the case, the measurements shall continue until two of the values are within a dB range of each other In the absence of specific knowledge of uncertainty for vehicles, the uncertainty shall be considered equal to KA = dB The actual uncertainty may be larger if the noise emission of the vehicles is unstable A.8 Determining the time averaged A-weighted sound power level using the time averaged A-weighted sound pressure levels over the measurement surface A.8.1 Determination of the time averaged A-weighted measured sound pressure levels over the measurement surface The sound pressure calculation shall be determined using the series of equations that are shown below The time-averaged A-weighted sound pressure level, averaged over the measurement surface, L p, Aeq,T , in decibels (reference 20 µPa), shall be calculated from the measured values of the equivalent continuous Aweighted sound pressure levels by means of the following equation: 1 n 0,1·L p, Aeq,i 10 L p, Aeq,T = 10 lg n i =1 ∑ (A.2) where L p, Aeq,i is the time-averaged A-weighted sound pressure level resulting from the i-th microphone position, in decibels (reference: 20 µPa); n=6 is the total number of microphone positions A.8.2 A-weighted sound power level calculation The A-weighted sound power levels of the vehicle shall be calculated applying the following equation to each series of measurements: S LWA = L pAeq ,T + 10 lg S0 (A.3) 61 BS EN 16029:2012 EN 16029:2012 (E) where 2 S is the area of the measurement surface, in m (S = 2πr ); S0 = 1m ; S 10 lg S0 = 20 for m radius, and 28 for 10 m radius The environmental correction has been ignored in line with A.4 The results of the series of measurements indicated in A.7 are used to determine the corresponding results for the A-weighted sound power level, LWA The arithmetic mean of the two highest sound power levels that are within a dB range of each other is taken A.9 Information to be recorded A.9.1 Vehicle under test The following information shall be compiled: a) vehicle manufacturer; b) model; c) serial number; d) vehicle arrangement, including major attachments A.9.2 Acoustic environment The following information shall be noted down: a)
