+AMD1:2020+AMD2:2025 CSV 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 62552-2:2015+AMD1:2020+AMD2:2025 CSV 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，并规定了用于检查这些特性的测试方法。IEC 62552 的本部分描述了性能要求的测定方法。尽管不同测试的设置有一定共通性（因此，可能将所有测试应用于同一样品具有优势），但这些测试是分别用于评估被测样品的特定特性。IEC 62552 的本部分并未规定从样品测试结果推断出所选样本所在总体特性的通用程序。IEC 62552-1、IEC 62552-2 和 IEC 62552-3 取代并替换了2007年发布的IEC 62552第一版。IEC 62552-1、IEC 62552-2 和 IEC 62552-3 作为一个技术修订版，相比IEC 62552:2007，包含了以下重大技术变更： - 第2部分（本部分）增加了一项冷却能力测试。 - 第2部分（本部分）增加了一项降温测试。 - 第2部分（本部分）为葡萄酒存储器具增加了性能测试。 [外文原描述]： CORRECTED VERSION 2026-02 IEC 62552-2:2015+AMD1:2020+AMD2:2025 CSV 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). This corrected version of IEC 62552-2:2015+AMD1:2020+AMD2:2025 CSV incorporates the following correction: – Addition of normative reference IEC 62552-1:2015/AMD1:2020
