标准范围

IEC 60904-2:20 23给出了光伏基准器件的分类、选择、包装、标记、校准和保养的要求。本文件适用于用于测量自然或模拟阳光辐照度的光伏（PV）参考设备，以量化光伏设备（电池、模块和阵列）的电气性能。它不包括在集中阳光下使用的光伏参考器件。这第四版取消并取代了2015年出版的第三版。与上一版相比，此版本包括以下重大技术变更:a)通过扩展相应的条款12和13，增加了用于在最大功率下校准PV设备的校准程序；b)修订了光谱响应度、温度系数和线性度强制测量的要求，视使用情况而定，并允许在等效设备上进行一些测量；c)对内置分流电阻的修订要求；d)明确增加了校准可追溯性的要求。

IEC 60904-2:2023 gives requirements for the classification, selection, packaging, marking, calibration and care of photovoltaic reference devices. This document applies to photovoltaic (PV) reference devices that are used to measure the irradiance of natural or simulated sunlight for the purpose of quantifying the electrical performance of photovoltaic devices (cells, modules and arrays). It does not cover photovoltaic reference devices for use under concentrated sunlight. This fourth edition cancels and replaces the third edition published in 2015. This edition includes the following significant technical changes with respect to the previous edition:
a) added calibration procedures for calibrating PV devices at maximum power by extending the respective Clauses 12 and 13;
b) revised requirements for mandatory measurement of spectral responsivity, temperature coefficients and linearity, depending on usage and allowing some measurements on equivalent devices;
c) revised requirements for built-in shunt resistor;
d) added requirements for traceability of calibration explicitly.
