量块计量保证方案(MAP)

Measurement assurance program of gauge block

量块计量保证方案(MAP)是美国NIST近年来推行的一种科学的量值传递方法。它打破了传统的量值传递方法,采用l检验和F检验对量值传递过程进行控制,并通过数据反馈对参加试验室进行综合考核,以确保量值传递的质量。介绍了在我国推广应用量块计量保证方案的实施情况,并进行了技术分析。

Measurement assurance program (MAP) of gauge block is one kind of scientific transfer method for value of a quantity. This program breaks through the traditional calibration chain. The program adopts t and F checks to control the process of value transfer, and examines the participant laboratories comprehensively through analysing return data to guarantee the quality of value transfer. This paper presents the applied circumstances of the MAP of gauge block in our country, and carries out a technical analysis.
