Scope

This standard specifies the implementation of tests, parameter measurement, data processing, performance curve drawing, and test reports for motor reciprocating pumps (hereinafter referred to as "pumps").
This standard includes two measurement accuracy levels: Level 1 is suitable for high-precision tests, and Level 2 is suitable for general-precision tests. The two measurement accuracy levels include different tolerance coefficient values, allowable fluctuation values, and measurement error limits.
This standard is applicable to pumps without any piping accessories, as well as to pump assemblies with piping accessories.
