Common use of dB(A Clause in Contracts

dB(A. 2.1.1. Selected mode for tests of the vehicle in motion: ................................" Paragraph 2.2., amend to read: "2.2. Sound level of stationary vehicle: .......... dB(A) at ........ min-1 in mode ………………1 Sound level of stationary vehicle: .......... dB(A) at ........ min-1 in mode ………………1 Sound level of stationary vehicle: .......... dB(A) at ........ min-1 in mode ………………1 Sound level of stationary vehicle: .......... dB(A) at ........ min-1 in mode ………………1 Sound level of stationary vehicle: .......... dB(A) at ........ min-1 in mode ………………1" 3.1.2.1. last indent, replace 3.1.2.1.4.1.(e) with 3.1.2.1.4.1.(d). 3.1.2.1.1. amend to read: 3.1.2.1.1. Power to mass ratio index (PMR) PMR is defined as follows: PMR = (Pn / mro) * 1000 kg/kW, where Pn is measured in kW and mro is measured in kg and defined according to paragraph 2.4. of the main body. 1. of Annex 3 to this Regulation. Specified power for non-combustion engines shall be the power stated by the manufacturer. The PMR with no dimension is used for the calculation of acceleration." 3.1.2.1.4.1. amend to read: 3.1.2.1.4.1. Vehicles with manual transmission, automatic transmissions, adaptive transmissions or CVTs tested with locked gear ratios The following conditions for selection of gear ratios are possible: (a) If one specific gear ratio gives an acceleration in a tolerance band of ±5 per cent of the reference acceleration awot ref, not exceeding 2.0 m/s², test with that gear ratio; (b) If none of the gear ratios give the required acceleration, then choose a gear ratio i, with an acceleration higher and a gear ratio i+1, with an acceleration lower than the reference acceleration. If the acceleration value in gear ratio i does not exceed 2.0 m/s², use both gear ratios for the test. The weighting ratio in relation to the reference acceleration awot ref is calculated by: k = (awot ref – awot (i+1))/(awot (i) – awot (i+1)) (c) If the acceleration value of gear ratio i exceeds 2.0 m/s², the first gear ratio shall be used that gives an acceleration below 2.0 m/s² unless gear ratio i+1 (or i+2, or i+3 or …) provides acceleration less than aurban. In this case, two gears, i and i+1 (or i+2, or i+3 or …) shall be used, including the gear i with acceleration exceeding 2.0 m/s². In other cases, no other gear shall be used. The achieved acceleration awot test during the test shall be used for the calculation of the part power factor kP instead of awot ref; (d) If rated engine speed is exceeded in a gear ratio i before the vehicle passes BB' the next higher gear i+1 shall be used. If the next higher gear i+1 results in an acceleration below aurban, the vehicle test speed, vtest, in the gear ratio i shall be reduced by 2.5 km/h and the gear ratio selection shall proceed as specified by the options given in this paragraph. In no case shall the vehicle test speed be reduced below 40 km/h; If the rated engine speed is exceeded in gear ratio i before the vehicle passes BB' and the vehicle test speed is equal to 40 km/h, the higher gear ratio i+1 is allowed even if awot test does not exceed aurban; The vehicle test speed in the higher gear ratio i+1 shall be 50 km/h; (e) If no gear ratio is available with an acceleration below 2.0 m/s², the manufacturer shall, if possible take measures to avoid an acceleration value awot test greater than 2.0 m/s². Table 1 in Appendix to Annex 3 provides examples for valid measures to control the downshift of gears or to avoid accelerations beyond 2.0 m/s². Any measure used by manufacturer for the above-mentioned purposes shall be documented in the test report." 3.1.2.2. amend to read: "3.1.2.2. Vehicles of categories M2 > 3,500 kg technically permissible maximum ▇▇▇▇▇ ▇▇▇▇, ▇▇, ▇▇, ▇▇: […] 26.1. shall be ensured. Target conditions of category ▇▇, ▇▇: When the reference point passes line BB', the engine speed nBB' shall be between 85 and 89 per cent of speed S, at which the engine develops its rated maximum net power, and the vehicle speed shall be 35 km/h ± 5 km/h. Between line AA' and line BB' a stable acceleration condition according to definition 2.26.1. shall be ensured." 3.1.2.2.1.1. amend to read: 3.1.2.2.1.1. Manual transmission, automatic transmissions, adaptive transmissions or transmissions with continuously variable gear ratios (CVTs) tested with locked gear ratios 26.1. shall be ensured. The gear choice is determined by the target conditions. 2.2. of Annex 3 to this Regulation are possible: (a) If one gear choice fulfils both target conditions for the rotational engine speed ntarget BB’ and for the vehicle speed vtarget BB’, test with that gear; (b) If more than one gear choice fulfils both target conditions for the rotational engine speed ntarget BB’ and for the vehicle speed vtarget BB’, test in gear i that gives velocity vBB’ gear i closest to 35 km/h; (c) If two gear choices fulfil both target conditions for the rotational engine speed ntarget BB’ and for the vehicle speed vtarget BB’, and fulfil the following condition. (vtarget BB’ – vBB’ gear i) = (vBB’ gear i+1 – vtarget BB’) then both gears are taken for further calculation of Lurban; (d) If one gear choice fulfils the target condition for the rotational engine speed ntarget BB’ but not the target condition for the vehicle speed vtarget BB’, use two gears, gearx and ▇▇▇▇▇. The target conditions for the vehicle speed for these two gears are as follows: gearx
