Reciprocating internal combustion compression-ignition engines. Apparatus for measurement of the opacity and for determination of the light absorption coefficient of exhaust gas Ingestion-build-63436 This Section of BS 64691 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.
