22、, power is transmitted and controlled through a pressurized liquid within an enclosed circuit. Contaminants present in the circulating working liquid can degrade system performance. The presence of particles residual from the manufacturing and assembly processes can cause a substantial increase in t
23、he wear rates to the system during the initial run-up and early life and can even cause catastrophic failures. In order to achieve reliable performance of components and the system, control over the amount of particles introduced during the build phase is necessary. Accurate assessment of the effect
24、iveness of part and component cleaning requires documentation of both the cleanliness requirement and the methods used for contaminant extraction and analysis and data reporting.vi ISO 2015 All rights reservedBS ISO 18413:2015Hydraulic fluid power Cleanliness of components Inspection document and pr
