GB/T 18403.1-2022Expression of performance of gas analyzers - Part 1: General (English PDF)

GB/T 18403.1-2022 is the English-translated version of 气体分析器性能表示 第1部分：总则.

GB/T 18403.1-2022 is the Chinese standard "Expression of performance of gas analyzers - Part 1: General". Its scope clause reads: This document applies to gas analyzers for the determination of the composition of gas mixtures.

This document specifies the terms, definitions, requirements and test methods for gas analyzers (hereinafter referred to as analyzers). Other parts of this series of standards Parts, such as GB/T 18403.2, describe special types of analyzers using high-temperature electrochemical sensors.

This document is consistent with the provisions in GB/T 6592 and IEC 60770. This document applies to analyzers that are permanently installed in any location (indoor or outdoor), as well as to sample handling systems and in-situ measurement techniques. technical analyzer.

This document applies to a complete set of analyzers provided by the same manufacturer, including all mechanical, electrical and electronic components of the analyzer.

The same applies to sensor units and electronics units from different manufacturers. For the purposes of this document, any AC or DC regulated power supply supplied or specified by the manufacturer, whether or not connected to the analyzer Installations are integrated and are considered part of the analyzer.

For safety requirements, refer to the relevant provisions of IEC 61010-1. If one or more components of the sample are flammable and air or a gas mixture containing oxygen or other oxidizing components is present, then Concentration ranges of reactive components are restricted outside the flammable range.

For the standard range of analog DC and pneumatic signals in process control systems, refer to the relevant provisions of IEC 60381-1 and IEC 60382. For the method of selecting the test value of influence quantity, refer to the relevant regulations of IEC 60654.

Please refer to the relevant provisions of IEC 61187 for the file requirements of the analyzer. See ISO 31-0 for general principles concerning quantities, units and symbols, and see ISO 1000.

This document does not apply to ancillary devices such as recorders, analog-to-digital converters or data acquisition systems used in conjunction with analyzers, but when two or When more analyzers are combined and sold as a system, and only one electronic unit is provided to continuously measure several parameters, these readouts The output components are considered to be part of the analyzer, and the EMF-current or EMF-voltage converters integrated with the analyzer also include included.

Purpose of this document. ---Specify general terms and definitions related to the performance of analyzers for continuous measurement of gas composition; --- Unify the methods used to manufacture and test the performance characteristics of such analyzers; --- Specifies the tests and test methods required to determine the functional characteristics; --- Provide basic information to support the application of ISO 9001 quality assurance standards. Its clauses include scope and purpose.
