applies to the speed sensor only; if vehicle speed is used to determine parameters like acceleration, the product of speed and positive acceleration, or RPA, the speed signal shall have an accuracy of 0.1 % above 3 km/h and a sampling frequency of 1 Hz. This accuracy requirement can be met by using a wheel rotational speed signal.
 [23] only applicable if vehicle speed is determined by the ECU; to meet the permissible tolerance it is permitted to adjust the ECU vehicle speed measurements based on the outcome of the validation test.
 [24] parameter only mandatory if measurement required for compliance with the limits.
 [25] PN measurement equipment in accordance with Annex B5 of UN Regulation No 154.
