标准范围

ISO指南35:2006给出了统计原则，以帮助理解和开发有效的方法，为参考材料的特性赋值，包括评估其相关的不确定度，并建立其计量溯源性。经过ISO指南35:2006中所述所有步骤的标准物质（RMs）通常附有证书，称为认证标准物质（CRM）。本指南将有助于充分发挥CRM作为辅助工具的潜力，以确保国家或国际范围内测量结果的可比性、准确性和兼容性。为了跨国界和随时间进行可比性，测量需要可追溯到适当的和规定的参考。在化学、生物和物理等涉及材料和/或样品的科学中，标准物质管理系统在实现测量结果可追溯性的概念方面发挥着关键作用。实验室将这些标准物质用作易于获取的测量标准，以建立其测量结果与国际标准的可追溯性。CRM携带的财产价值可以在生产过程中追溯到国际单位制或其他国际商定的单位。ISO指南35:2006解释了如何开发方法，以获得可靠的财产价值，这些价值可追溯到适当的规定参考。它涵盖了非常广泛的材料（基质），从气体混合物到生物材料，以及非常广泛的性质，从化学成分到物理和免疫分析性质。

ISO Guide 35:2006 gives statistical principles to assist in the understanding and development of valid methods to assign values to properties of a reference material, including the evaluation of their associated uncertainty, and establish their metrological traceability. Reference materials (RMs) that undergo all steps described in ISO Guide 35:2006 are usually accompanied by a certificate and called a certified reference material (CRM). This Guide will be useful in establishing the full potential of CRMs as aids to ensure the comparability, accuracy and compatibility of measurement results on a national or international scale.In order to be comparable across borders and over time, measurements need be traceable to appropriate and stated references. CRMs play a key role in implementing the concept of traceability of measurement results in chemistry, biology and physics among other sciences dealing with materials and/or samples. Laboratories use these CRMs as readily accessible measurement standards to establish traceability of their measurement results to international standards. The property values carried by a CRM can be made traceable to SI units or other internationally agreed units during production. ISO Guide 35:2006 explains how methods can be developed that will lead to well established property values, which are made traceable to appropriate stated references. It covers a very wide range of materials (matrices), ranging from gas mixtures to biological materials, and a very wide range of properties, ranging from chemical composition to physical and immunoassay properties.
