Reciprocating internal combustion compression-ignition engines — Apparatus for measurement of the opacity and for determination of the light absorption coefficient of exhaust gas

Moteurs alternatifs à combustion interne à allumage par compression — Appareillage de mesure de l'opacité et du coefficient d'absorption de la lumière des gaz d'échappement

Abstract / scope

This International Standard specifies the general requirements and the installation of apparatus for measurement of

the opacity and for the determination of the light absorption coefficient of exhaust gas from internal combustion

engines (not confined to road vehicles). These instruments are known as opacimeters.
