IEC 62552-2:2015规定了通过内部自然对流或强制空气循环冷却的家用制冷设备的基本特性，并规定了检查这些特性的试验方法。IEC 62552的本部分描述了确定性能要求的方法。虽然不同测试的设置有一些共同之处（因此将它们全部应用于一个样本可能是一个优势），但这些是单独的测试，用于评估被测试样本的特定特性。IEC 62552的这一部分没有规定将样本测试结果的结果概括为对从中选择样本的整个群体特征的预测的程序。 IEC 62552-1、IEC 62552-2和IEC 62552-3取消并取代了2007年发布的第一版IEC 62552。IEC 62552-1、IEC 62552-2和IEC 62552-3共同构成技术修订版，并包括以下与IEC 62552:2007有关的重大技术变更:第2部分（本部分）中增加了冷却能力试验。第2部分（本部分）中增加了下拉试验。第2部分（本部分）增加了葡萄酒储存设备的性能测试。交叉引用:EN 60704-2-14IEC 62552-3:2015IEC 62552-1:2015EN 62552-3:2020EN 62552-1:2020购买本文件时提供的所有现行修订版均包含在购买本文件中。

IEC 62552-2:2015 specifies the essential characteristics of household refrigerating appliances cooled by internal natural convection or forced air circulation, and specifies test methods for checking the characteristics. This part of IEC 62552 describes the methods for the determination of performance requirements. Although there is some commonality in the set-ups for different tests (and so it may be an advantage to apply them all to one sample), these are separate tests to evaluate specific characteristics of the sample being tested. This part of IEC 62552 does not specify a procedure to generalise the results from sample test results to a prediction of the characteristics of the whole population from which that sample was selected. IEC 62552-1, IEC 62552-2 and IEC 62552-3 cancel and replace the first edition of IEC 62552 published in 2007. IEC 62552-1, IEC 62552-2 and IEC 62552-3 together constitute a technical revision and include the following significant technical changes with respect to IEC 62552:2007:A cooling capacity test has been added in Part 2 (this part).A pull-down test has been added in Part 2 (this part).Performance tests have been added for wine storage appliances in Part 2 (this part).Cross References:EN 60704-2-14IEC 62552-3:2015IEC 62552-1:2015EN 62552-3:2020EN 62552-1:2020All current amendments available at time of purchase are included with the purchase of this document.
