家用制冷器具 特性和试验方法 第2部分：性能要求

[中文适用范围]： IEC 62552的本部分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器具的基本特性，并规定了检查这些特性的测试方法。 IEC 62552 的这一部分描述了确定性能要求的方法。尽管不同测试的设置存在一些共性（因此将它们全部应用于一个样本可能是一种优势），但这些是单独的测试，用于评估所测试样本的特定特征。 IEC 62552 的这一部分没有指定将样本测试结果概括为对所选样本的整个群体特征的预测的程序。 [外文原描述]： 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).
