ISO 17769-1:2012规定了与通过旋转动力和容积式液体泵及相关装置的液体流动相关的术语、字母符号和单位。它是澄清安装设计师、制造商、运营商和工厂建造商之间沟通的一种方式。它标识了常用的单位，但可以使用所有其他法定单位。 ISO 17769-1:2012仅涉及流速和泵头正值所描述的条件。

ISO 17769-1:2012 specifies terms, letter symbols and units related to the flow of liquids through rotodynamic and positive displacement liquid pumps and associated installations. It serves as a means of clarifying communications between the installation designer, manufacturer, operator and plant constructor. It identifies the units in common usage, but all additional legal units can be used. ISO 17769-1:2012 deals solely with conditions described by positive values for the rate of flow and pump head.
