使用有证标准样品、标准样品和质量控制样品均有助于评价测量不确定度,尤其是在测试领域。很多实验室制定了质量控制图表,以监视实验室对某个给定样品(和给定特性值)的测试性能。以下介绍用有证标准样品(CRM)评价测量不确定度。CRMs的常用用途之一是确定实验室的性能。按照CRM
The use of certified standard samples, standard samples and quality control samples are helpful to evaluate the measurement uncertainty, especially in the field of testing. Many laboratories have developed quality control charts to monitor laboratory performance for a given sample (and for a given property value). The following describes the use of certified reference sample (CRM) evaluation of measurement uncertainty. One of the common uses of CRMs is to determine the lab’s performance. Follow CRM
