1.1 ISO 13256的本部分为工厂制造的住宅、商业和工业、电动、机械压缩型、水对空气和盐水对空气热泵建立了性能测试和评级标准。ISO 13256本部分中包含的测试和评级要求基于匹配组件的使用。1.2根据ISO 13256本部分的规定，设计用于一次应用的设备可能不适用于ISO 13256本部分所涵盖的所有应用。1.3 ISO 13256本部分不适用于单独使用的独立组件的测试和评级，也不适用于ISO 5151、ISO 13253或ISO 13256所涵盖的热泵的测试和评级- 2.

1.1 This part of ISO 13256 establishes performance testing and rating criteria for factory-made residential, commercial and industrial, electrically-driven, mechanical-compression type, water-to-air and brine-to-air heat pumps. The requirements for testing and rating contained in this part of ISO 13256 are based on the use of matched assemblies.1.2 Equipment designed for rating at one application under this part of ISO 13256 may not be suitable at all applications covered in this part of ISO 13256.1.3 This part of ISO 13256 does not apply to the testing and rating of individural assemblies for separtate use, nor to the testing and rating of heat pumps covered in ISO 5151, ISO 13253 or ISO 13256-2.
