• Expression of performance of gas analyzers - Part 7: Tunable semiconductor laser gas analyzers (utilizing tunable semiconductor laser absorption spectroscopy)

  Käsitlusala:

  This part of IEC 61207 applies to all aspects of analyzers utilizing TSLAS for the concentration measurement of one or more gas components in a gaseous mixture or vapour. It should be used in conjunction with IEC 61207-1. It applies to analyzers utilizing tunable semiconductor lasers as sources and utilizing absorption spectroscopy, such as direct absorption, FMS, WMS, multi-pass absorption spectroscopy, CRDS, ICOS, PAS and CEAS techniques etc. It applies to analyzers which are of in situ or extractive type. The object of this part is: - to specify the terminology and definitions related to the functional performance of gas analyzers, utilizing tunable semiconductor laser gas absorption spectroscopy, for the continuous measurement of gas or vapour concentration in a source gas; - to unify methods used in making and verifying statements on the functional performance of such analyzers; - to specify what tests should be performed to determine the functional performance and how such tests should be carried out; - to provide basic documents to support the application of the standards of quality assurance contained in ISO 9001, ISO 9002 and ISO 9003.
