生态环境第三方检测机构计量器具量值溯源管理问题探讨

Discussion on the Regulation for Value Traceability of Measuring Instrument in the Third-Party Ecology and Environment Testing Institutions

构建科学、准确、有效的量值溯源体系是实验室质量管理的重要内容。在国家市场监督管理总局新发布的《实施强制管理的计量器具目录》中,涉及环境监测用途的类别大幅度减少。在此背景下,研究介绍了量值溯源中检定和校准的差异及适用范围,强调不应将检测作为量值溯源的方式。分类比较了国内现有具备量传能力的计量技术机构,对目前生态环境监测领域量值溯源技术方法与实际使用需求脱节、计量服务供给侧响应不及时的短板进行了总结。建议各专业计量技术委员会加快制修订相关计量技术法规,各计量技术机构及时更新和建立相关计量标准,从而更好地满足环境检测机构对计量器具量值管理的需求。

The construction of scientific,accurate and effective traceability system is an essential part of laboratory quality management.In the latest catalogue of compulsory management work measuring instruments issued by the State Administration for Market Regulation,the number of measuring instruments that are required to be subject to compulsory verification for environmental testing has been greatly reduced.This paper introduces the difference and application scope of verification and calibration in the traceability of measuring instruments while figures out that testing should not be recognized as a way of value tracing.The existing metrological technical institutions with capacity of data transmission in China are classified and compared.This research summarizes the disconnection between the measurement traceability technology and the demand,and the lack of timely response from the supply side of measurement service.It is suggested that the professional metrology technical committees should speed up the formulation and revision of corresponding measurement technical regulations.The metrological technical institutions should update and establish relevant measurement standards in time to meet the needs of environmental testing institutions for the value management of measuring instruments.
