This standard specifies the test implementation, parameter measurement, data processing, performance curve plotting and test report of power reciprocating pump (hereinafter referred to as "pump").
This standard includes two measurement precision grades: Grade 1 is applicable to high-precision test while Grade 2 is applicable to general-precision test. The two measurement precision grades include different tolerance coefficients, allowable fluctuations and measurement error limits.
This standard is applicable not only to pumps without any pipeline accessories, but also to pump assemblies with pipeline accessories.
