IEC 62552-1:20 15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，并建立了检查特性的测试方法。出于声明的目的，IEC 62552本部分中定义的试验被认为是评估制冷设备基本设计和操作的型式试验。IEC 62552的这一部分没有定义生产取样或合格评定或认证的要求。IEC 62552的这一部分没有定义验证测试的制度，因为这因地区和国家而异。当需要验证与本标准相关的给定类型的制冷设备的性能时，在可行的情况下，最好将所有规定的测试应用于单个单元。这些测试也可以单独进行，以研究特定的特性。IEC 62552-1、-2和-3取消并取代2007年发布的IEC 62552第一版。IEC 62552-1、-2和-3构成技术修订版，包括相对于IEC 62552:2007的以下重大技术变更: a)标准的所有部分都进行了大量重写和更新，以应对新的测试要求、新的产品配置、电子产品控制和基于计算机的测试室数据收集和处理设备的出现。 b)在第1部分（本部分）中，对测试室设备规格和测试设置进行了一些更改，以提供额外的灵活性，尤其是在单个测试室中测试多个设备时。

IEC 62552-1:2015 specifies the essential characteristics of household refrigerating appliances, cooled by internal natural convection or forced air circulation, and establishes test methods for checking the characteristics. For the purposes of declaration, the tests defined in this part of IEC 62552 are considered to be type tests to assess the fundamental design and operation of a refrigerating appliance. This part of IEC 62552 does not define requirements for production sampling or conformity assessment or certification. This part of IEC 62552 does not define a regime for verification testing as this varies by region and country. When verification of the performance of a refrigerating appliance of a given type in relation to this standard is necessary, it is preferable, wherever practicable, that all the tests specified be applied to a single unit. The tests can also be made individually for the study of a particular characteristic. IEC 62552-1, -2 and -3 cancel and replace the first edition of IEC 62552 published in 2007. IEC 62552-1, -2 and -3 constitute a technical revision and includes the following significant technical changes with respect to IEC 62552:2007:
a) All parts of the standard have been largely rewritten and updated to cope with new testing requirements, new product configurations, the advent of electronic product controls and computer based test-room data collection and processing equipment.
b) In Part 1 (this part) there are some changes to test room equipment specifications and the setup for testing to provide additional flexibility especially when testing multiple appliances in a single test room.
