标准摘要
[中文适用范围]: 本文阐述了在测量过程中使用参考物质(RMs),特别是经认证参考物质(CRMs)的良好实践。这些应用包括:评估测量方法的精密度和正确度;质量控制;确定物质特性量值;校准;建立常规标尺。本文还将各类参考物质的关键特性与其不同应用进行了关联。参考物质用于校准的制备工作亦属于ISO 17034和ISO 33405的范畴。本文内容仅涵盖实验室用于校准其设备的小型参考物质制备及量值赋值的原理。此类参考物质的大规模生产(可能旨在分发)则不在本文范围内,该类活动已在ISO 17034和ISO 33405中予以规定。 [外文原描述]: This document describes good practice in using reference materials (RMs), and certified reference materials (CRMs) in particular, in measurement processes. These uses include: — the assessment of precision and trueness of measurement methods; — quality control; — assigning values to materials; — calibration; — establishing conventional scales. This document also relates key characteristics of various types of RMs to the different applications. The preparation of RMs for calibration is also part of the scope of ISO 17034 and ISO 33405. The treatment in this document is limited to the fundamentals of small-scale preparation of RMs and the value assignment, as used by laboratories to calibrate their equipment. Larger scale production of such RMs, with the possible aim of distribution, is beyond the scope of this document. This type of activity is covered in ISO 17034 and ISO 33405.
