scope:

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 applies to analyzers utilizing tuneable 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 both to in situ or extractive type analyzers. This standard includes the following, it - specifies the terms and definitions related to the functional performance of gas analyzers, utilizing tuneable semiconductor laser gas absorption spectroscopy, for the continuous measurement of gas or vapour concentration in a source gas, - unifies methods used in making and verifying statements on the functional performance of this type of analyzers, - specifies the type of tests to be performed to determine the functional performance and how to carry out these tests, - provides basic documents to support the application of the standards of quality assurance with in ISO 9001
