This International Standard defines methods to measure the cleanliness of a fluid in an assembled hydraulic fluid power system, to verify a required system cleanliness upon release of the system from the production area, and if needed, to clean the system to the required cleanliness level. The clean-up procedure specified in this International Standard is not intended to replace proper system flushing procedures; see ISO23309 for a system flushing procedure. Components and parts used in such systems should be clean prior to assembly; see ISO18413 for guidance.
