Full title and description

Expression of performance of gas analyzers - Part 6: Photometric analyzers. This International Standard specifies terminology, performance expression and test methods for gas analyzers that use photometric techniques (absorption, emission, wavelength-derivative and related methods) for continuous measurement of gas or vapor concentrations.

Abstract

IEC 61207-6:2014 provides unified methods for stating and verifying the functional performance of photometric gas analyzers and describes the tests required to determine performance characteristics and uncertainties. It is intended to be used together with the general requirements of IEC 61207-1 and updates and replaces the earlier 1994 edition.

Scope

Applies to analyzers that utilise photometric techniques (including non-dispersive and dispersive wavelength selection and methods based on absorption, emission or wavelength derivatives) for the continuous measurement of one or more gas or vapour components. The standard covers analyzers receiving conditioned or unconditioned samples as well as in-situ measurements and defines what tests and statements are needed to characterise functional performance and measurement uncertainty. It is intended to be read in conjunction with IEC 61207-1 (general principles for expression of performance of gas analyzers).

Key topics and requirements

• Terminology and definitions specific to photometric gas analyzers.
• Unified methods for expressing functional performance (sensitivity, range, response time, stability, selectivity, interference characteristics).
• Test procedures to determine measurement uncertainty and to verify performance claims.
• Requirements for reporting results and for the presentation of performance data so buyers and users can compare analyzers.
• Guidance to support quality assurance and traceability in performance statements (links to ISO 9001 concepts where applicable).

These topics and requirements are established to harmonize how manufacturers and testing bodies determine and report analyzer performance.

Typical use and users

Used by manufacturers of photometric gas analyzers, test laboratories, procurement engineers, instrumentation and process engineers in industries such as environmental monitoring, combustion control, petrochemical and chemical processing, and laboratory settings where accurate gas concentration measurements are required. The standard helps users interpret supplier performance claims and design appropriate acceptance tests.

Related standards

IEC 61207-6 is part of the IEC 61207 series (expression of performance of gas analyzers) and is intended to be used with IEC 61207-1 (general requirements). National and regional adoptions / translations (EN versions) exist for use within regional standards frameworks. The 2014 edition cancels and replaces IEC 61207-6:1994.
