美国国家标准与技术研究所（NIST）
The National Institute of Standards and Technology (NIST), U.S. Department of Commerce, is the Federal agency responsible for developing, maintaining and disseminating national metrology standards – realizations of the International System of Units (SI) – for the basic measurement quantities, and for many derived measurement quantities. Measurement results throughout the U.S., and indeed the world, are traceable to NIST’s realizations of the SI. In turn, NIST establishes the traceability of its own measurement results and the values of its own standards while operating in accordance with the NIST Quality System. The NIST Quality System is based on ISO/IEC 17025:2017 for its measurement and calibration functions. ISO 8000 is used as the relevant standard for functions specific to the development and availability of NIST Standard Reference Data. ISO 17034 is used as the relevant standard for functions specific to the development and production of Certified Reference Materials, called NIST Standard Reference Materials (SRMs). The Quality System for the delivery of measurement services is based on ISO 9001. Conformance to these standards for the NIST laboratories and divisions performing and delivering measurement services has been verified using an assessment process administered by NIST’s Quality Manager as described in the quality manual NIST-QM-I.
美国国家标准与技术研究所（NIST）是联邦机构负责制定、维护和传播国家计量标准——国际单位制（SI）-用于基本测量量和许多衍生测量量。美国乃至全世界的测量结果可追溯到NIST对SI。反过来，NIST建立了自身测量结果和自身标准值的可追溯性，同时按照NIST质量体系运行。NIST质量体系基于ISO/IEC 17025:2017用于其测量和校准功能。ISO 8000用作特定于NIST标准参考数据的开发和可用性。ISO 17034被用作特定于开发和生产认证参考材料的功能，称为NIST标准参考材料（SRM）。提供测量服务的质量体系基于ISO 9001。执行和交付测量的NIST实验室和部门是否符合这些标准已使用NIST质量经理管理的评估过程对服务进行了验证，如质量手册NIST-QM-I。
