The National Institute of Standards and Technology (NIST), formerly the National Bureau of Standards, was established by the US Congress in 1901 and charged with establishing a measurement foundation to facilitate US and international commerce. This broad language provides NIST with the ability to establish and implement its programs in response to changes in national needs and priorities. This review traces some of the changes in NIST's reference material programs over time and presents the NIST Material Measurement Laboratory's current approach to promoting accuracy and metrological traceability of chemical measurements and validation of chemical measurement processes.
美国国家标准与技术研究院（NIST），前身为国家标准局，由美国国会于 1901 年成立，负责建立一个计量基础，以促进美国和国际商业。这种广义的语言使 NIST 能够根据国家需求和优先事项的变化来制定和实施其计划。本审查追溯了 NIST 基准物质计划随时间的变化，并介绍了 NIST 材料测量实验室目前如何促进化学测量的准确性和计量溯源性以及化学测量过程的验证。
