本文件适用于压缩机驱动的制冷系统（以下简称制冷系统）的性能测试，该系统根据蒸汽压缩原理运行，由压缩、冷凝和冷却电路部件组成，以及整个制冷回路所需的连接管和任何必要的相关辅助设备。 本文件不适用于其他制冷系统的测试，如吸收式或蒸汽喷射式制冷系统。 本文件不包括针对特定用途的制冷系统适用性测试，如家用冰箱、商用冷藏柜和展示柜、空调。 本文件包括在实验室外进行的测试，或不存在系统的特定实验室测试标准的情况下，根据约定的操作条件进行的测试。

This document applies to the performance testing of compressor driven refrigerating systems (hereafter referred to as refrigerating systems) that operate according to the principle of vapour compression and consist of the circuit parts for compression, condensation, and evaporation as well as the connecting pipes and any necessary associated ancillaries required for a complete refrigeration circuit. This document does not apply to the testing of other refrigeration systems such as absorption or steam jet refrigerating systems. Testing of the suitability of a refrigerating system for a specific use, such as household refrigerators, refrigerated commercial and display cabinets, air conditioners, is not covered by this document. This document includes testing outside laboratories or where specific laboratory testing standards for systems do not exist and which is performed according to agreed operating conditions.
