IEC 61207-6:2014 气体分析器性能表示 第6部分:光度分析器

Scope and object This part of IEC 61207 applies to all aspects of analyzers using photometric techniques for the measurement of concentration of one or more components in a mixture of gases or vapors. It should be used in conjunction with IEC 61207-1. For photometric analyzers utilizing tuneable semiconductor laser absorption spectroscopy (TSLAS) for gas measurements@ IEC 61207-7 should also be referred to. This part of IEC 61207 applies to analyzers using non-dispersive and dispersive wavelength selection and using absorption@ emission@ wavelength derivative or scattering techniques. It applies to analyzers which receive either a conditioned or unconditioned sample of gas either under vacuum@ at ambient pressure or pressurized. It applies to analyzers which measure gas concentrations directly within the sample gas. The object of this part is: ?C to specify the terminology and definitions related to the functional performance of gas analyzers@ utilizing a photometric analyzer@ for the continuous measurement of gas or vapor concentration in a source gas; ?C to unify methods used in making and verifying statements on the functional performance of such analyzers; ?C to specify what tests should be performed to determine the functional performance and how such tests should be carried out; ?C to provide basic documents to support the application of standards of quality assurance ISO 9001.
