ISO 18740:2016适用于任何固定（恒定）速度、液冷、成套离心式空气压缩机，该压缩机包含由电动机驱动的任何类型的离心压缩元件。 它定义并描述了标准类型的电动成套空气压缩机的验收试验，这些压缩机按照制造商确定的规格制造，并根据制造商销售文件中公布的性能数据进行销售。 注:散装供应以供现场安装的项目不被视为压缩机组件的一部分。 此类压缩机设计用于从其周围环境中吸入大气，制造商提供的性能数据通常与正常环境空气入口压力有关。

ISO 18740:2016 applies to any fixed (constant) speed, liquid cooled, packaged centrifugal air compressor which incorporates a centrifugal compression element of any type driven by an electric motor. It defines and describes acceptance tests for electrically driven packaged air compressors of standard types which are constructed to specifications determined by the manufacturer and which are sold against performance data published in the manufacturer's sales documentation. NOTE Items supplied shipped loose for installation at site are not considered to be a part of the compressor package. Such compressors are designed to draw in atmospheric air from their immediate surroundings and the performance data offered by the manufacturer usually relates to a normal ambient air inlet pressure.
