Road vehicles - Portable Emission Measuring Systems (PEMS) - Performance assessment

This document defines the procedures for assessing the performance of test equipment that is used for the on-road measurement of tailpipe emissions of light-duty vehicles, on the basis of a common test procedure that simulates the range of conditions experienced during on-road tests.
This document prescribes:
-   the tests to be conducted, and,
-   a procedure to determine, for any type of PEMS equipment, an appropriate uncertainty margin to reflect its performance over those conditions.
The key test variables are as follows (but not limited to the ones mentioned):
a)   temperature, humidity and pressure and step-wise or gradual changes,
b)   acceleration and deceleration (longitudinal and lateral),
c)   vibration, inclination and shock tests,
d)   instrument positioning on a vehicle,
e)   combinations of (1) to (4),
f)   cross-interferences,
g)   signal-processing, data treatment and time alignment, and
h)   calculation methods (excluding the regulatory post-processing of data).

Véhicules routiers - Systèmes portatifs de mesure des émissions (PEMS) - Vérification de la performance

Le présent document définit les procédures d'évaluation de la performance des équipements d’essai qui sont utilisés pour les mesures sur route d'émissions d'échappement de véhicules légers, sur la base d'une procédure d’essai commune simulant la gamme des conditions rencontrées pendant des essais sur route.
Le présent document spécifie :
-   les essais à réaliser, et
-   une procédure permettant de déterminer, pour tout type d’équipement PEMS donné, une marge d'incertitude appropriée afin de refléter sa performance dans toutes les conditions suivantes.
Les variables d'essai clés sont les suivantes (mais non limitées à celles mentionnées) :
a)   température, humidité et pression (y compris des variations échelonnées ou progressives),
b)   accélération et décélération (longitudinale et latérale),
c)   essai de vibrations, d'inclinaison et de chocs,
d)   positionnement de l'instrument sur un véhicule,
e)   combinaisons de (a) à (d),
f)   brouillages réciproques,
g)   traitement des signaux, traitement des données et alignement temporel, et
h)   méthodes de calcul (sauf post-traitement réglementaire des données).
