This standard specifies the selection of indicators, sampling regulations, fault criteria, test procedures and test data processing methods for pump reliability measurement tests. The reliability measurement test is a test to determine the characteristic value of the pump's reliability. The purpose is to determine the actual reliability level achieved by the pump so that this information can be recorded in the technical documentation. This standard is applicable to pump products for which reliability index values need to be known, and is applicable to both laboratory and on-site reliability testing methods.
