GB/T 15000.3-2008 标准样品工作导则(3).标准样品.定值的一般原则和统计方法

本部分给出的统计原理旨在帮助理解和制定为标准样品特性赋值的有效方法，包括评估有关不确定度和建立计量溯源性的方法。按照本部分描述的所有步骤制得的标准样品（RM）通常附有证书，并被称为有证标准样品（CRM）。本部分将有助于充分发挥CRM的潜力，以确保在国家或国际范围内测量结果的可比性、准确性和一致性。 为了能在时空上可比，测量需要溯源到适当和规定的测量标准。在化学、生物学和物理学尤其是涉及材料和/或样品的学科中，CRM在建立测量结果溯源性方面具有重要作用。实验室应用CRM作为易于获得的测量标准建立其测量结果与国际标准的溯源性。在CRM生产过程中，其特性值可以溯源到SI单位或其他国际协议单位。本部分阐明如何制定能很好地确定特性值的方法，使其可溯源到适当和规定的测量标准。本部分适用于从混合气体到生物样品的各种材料（基质）范围，也适用于从化学成分到物理和免疫检验特性的各种特性。 本部分所描述的方法不一定适用于RM生产和特性值（包括有关不确定度）确定的各个方面。可以认为本部分所给出的方法是大部分RM生产和赋值的主要方法，对一些特别的情况可能需要进行适当的修正。本部分所描述的统计方法通过举例说明了方法概要，并假定数据为正态分布。当数据不是正态分布时，最好采用其他统计方法，已获得有效地特性值及相应的不确定度。本部分还概述了生产CRM方案的设计。

ASTM G5-94(1999)e1 作静电位标记和动电位阳极极化测量的基准测试方法

1.1 This test method describes an experimental procedure for checking experimental technique and instrumentation. If followed, this test method will provide repeatable potentiostatic and potentiodynamic anodic polarization measurements that will reproduce data determined by others at other times and in other laboratories provided all laboratories are testing reference samples from the same lot of Type 430 stainless steel.1.2 Values stated in SI units are to be regarded as the standard. Inch-pound units given in parentheses are for information only.1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
