气体氧分析器国家计量检定规程的法规制定、修订以及在检定过程上的区别

Difference Among the Enactment and Amendment of Regulations and the Process of Testing about National Metrology Verification Regulation of Oxygen Analyzer

为了进一步完善氧计量法规,使我国该领域气体氧早日达到国际溯源的可比性,统一全国该组分量值,本文归纳了JJG365—2008《电化学氧测定仪》、JJG 945—1999《原电池法气体氧分析器》、JJG 662—2005《顺磁式氧分析器》、JJG 535—2004《氧化锆氧分析器》国家计量检定规程法规的制定、修订情况及其在规程检定原理、计量检定过程中技术指标(检定范围、响应时间、示值误差、稳定性、重复性等)的区别和判别,并指出了检定规程在执行过程中的注意事项。

In order to improve the oxygen measurement regulations further so that our country can achieve international comparability of the source in the field of oxygen gas at an early date and reunify components value countrywide.This article summarizes the enactment and amendment of regulations about national verification regulation including JJG365-2008＂electrochemical oxygen analyzer＂,JJG 945-1999＂galvanic cell oxygen analyzer＂,JJG 662-2005＂paramagnetic oxygen analyzer＂,JJG 535-2004＂zirconia oxygen analyzer＂,and it also depicted the difference and identification of the regulation verification principle and the technical index （verification range,response time,the indication error,stability,repeatability,etc.） in the process of verification.It elucidated the matters during the implementation process of the national verification regulation of oxygen analyzer.
