IEC 61829:2015规定了平板光伏(PV)阵列特性、伴随的气象条件的现场测量程序，以及将其转换为标准测试条件(STC)或其他选定条件的使用。与上一版相比，此新版本包括以下重大技术变更: -它解决了许多过时的程序； -它容纳常用的商业I-V曲线示踪剂； -它为解决现场不确定性提供了一种更实用的方法； -它删除并替换了参考其他更新的相关标准（包括IEC 60904系列和DIEC 60891）的程序。

IEC 61829:2015 specifies procedures for on-site measurement of flat-plate photovoltaic (PV) array characteristics, the accompanying meteorological conditions, and use of these for translating to standard test conditions (STC) or other selected conditions. This new edition includes the following significant technical changes with respect to the previous edition:
- it addresses many outdated procedures;
- it accommodates commonly used commercial I-V curve tracers;
- it provides a more practical approach for addressing field uncertainties;
- it removes and replaces procedures with references to other updated and pertinent standards, including the IEC 60904 series, andIEC 60891.
