本规定仅适用于容积式单级制冷剂压缩机。介绍了测定制冷量、功率、等熵效率和性能系数的选定试验方法。所述试验方法也可用作其他类型制冷剂压缩机的试验指南。-取代第一版（ISO 917:1974），并构成其技术修订版。

The provisions are applicable to single-stage refrigerant compressors of the positive-displacement type only. Selected test methods are described for the determination of the refrigerating capacity, power, isentropric efficiency, and the coefficient of performance. The test methods described may also be used as a guide for testing other types of refrigerant compressors. - Replaces the first edition (ISO 917:1974) and constitutes its technical revision.
