家用电器.备用电源的测量

[中文适用范围]： 本国际标准规定了待机模式和其他低功耗模式（关闭模式和网络模式）（如适用）下功耗的测量方法。它适用于额定输入电压或电压范围全部或部分在100Vac至250Vac（单相产品）和130Vac至480Vac（其他产品）范围内的电气产品。本标准的目的是提供一种测试方法，以确定一系列产品在相关低功耗模式（见 3.4）下的功耗，通常是在产品不处于活动模式（即不执行主要功能）的情况下。 [外文原描述]： IEC 62301:2011 specifies methods of measurement of electrical power consumption in standby mode(s) and other low power modes (off mode and network mode), as applicable. It is applicable to electrical products with a rated input voltage or voltage range that lies wholly or partly in the range 100 V a.c. to 250 V a.c. for single phase products and 130 V a.c. to 480 V a.c. for other products. The objective of this standard is to provide a method of test to determine the power consumption of a range of products in relevant low power modes (see 3.4), generally where the product is not in active mode (i.e. not performing a primary function). This standard does not specify safety requirements. It does not specify minimum performance requirements nor does it set maximum limits on power or energy consumption. This second edition cancels and replaces the first edition published in 2005 and constitutes a technical revision. The main changes from the previous edition are as follows: - greater detail in set-up procedures and introduction of stability requirements for all measurement methods to ensure that results are as representative as possible; - refinement of measurement uncertainty requirements for power measuring instruments, especially for more difficult loads with high crest factor and/or low power factor; - updated guidance on product configuration, instrumentation and calculation of measurement uncertainty; - inclusion of definitions for low power modes as requested by TC59 and use of these new definitions and more rigorous terminology throughout the standard; - inclusion of specific test conditions where power consumption is affected by ambient illumination.
