IEC指南115:2021可作为IEC指南115:2021 RLV提供，其中包含国际标准及其红线版本，显示了与上一版本相比技术内容的所有变化。IEC指南115:2021提出了一种实用的方法测量不确定度在电工行业合格评定活动中的应用。它是专门为IECEE计划以及根据国家安全标准测试电气产品的测试实验室设计的。它描述了测量不确定度原理的应用，并为进行测量不确定度计算提供了指导。它还给出了一些与产品合格评定测试测量计算不确定度相关的示例。IEC指南115由IECEE测试实验室委员会(CTL)编写，旨在为ISO/IEC 17025的测量不确定度要求在电气设备中的实际应用提供指导在IECEE CB计划内进行的trical安全测试。IECEE CB计划是一项多边国际协议，由40多个国家和约60个国家认证机构签署，用于接受按照IEC标准测试的电气产品的测试报告。除其他任务外，CTL的目的是确定对IEC标准测试方法的共同理解，并确保并不断提高成员实验室测试结果的重复性和再现性。本文件中概述的测量不确定度的实用方法已被IECEE方案所采用，并且也被世界各地从事电气产品测试以达到国家安全标准的测试实验室广泛使用。

IEC GUIDE 115:2021 is available as IEC GUIDE 115:2021 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

IEC Guide 115:2021 presents a practical approach to the application of uncertainty of measurement to conformity assessment activities in the electrotechnical sector. It is specifically conceived for use in IECEE Schemes as well as by testing laboratories engaged in testing electrical products to national safety standards. It describes the application of uncertainty of measurement principles and provides guidance on making uncertainty of measurement calculations. It also gives some examples relating to uncertainty of measurement calculations for product conformity assessment testing. IEC Guide 115 has been prepared by the IECEE Committee of Testing Laboratories (CTL) to provide guidance on the practical application of the measurement uncertainty requirements of ISO/IEC 17025 to the electrical safety testing conducted within the IECEE CB Scheme. The IECEE CB Scheme is a multilateral, international agreement, among over 40 countries and some 60 national certification bodies, for the acceptance of test reports on electrical products tested to IEC standards.The aim of the CTL is, among other tasks, to define a common understanding of the test methodology with regard to the IEC standards as well as to ensure and continually improve the repeatability and reproducibility of test results among the member laboratories. The practical approach to measurement uncertainty outlined in this document has been adopted for use in the IECEE Schemes, and is also extensively used around the world by testing laboratories engaged in testing electrical products to national safety standards.
