Over deze norm
This Publicly Available Specification specifies the metrological and technical requirements and tests for digital measuring instruments that serve to determine the volume fractions of certain components of the exhaust gases emanating from motor vehicles. The conditions with which such instruments shall comply in order to meet any OIML performance requirements are also established. This Publicly Available Specification is applicable to instruments, particularly those used according to the procedure defined in ISO 3929, intended for the inspection and maintenance of in-use motor vehicles with spark ignition engines. These instruments are used to determine the volume fraction of one or more of the following exhaust gas components: - carbon monoxide (CO), - carbon dioxide (CO2), - hydrocarbons (HC, in terms of n-hexane), and - oxygen (O2) at the moisture level of the sample as analysed.
