ISO 9632:1992 PDF

Scope: classification. This International Standard specifies a uniform repeatable test method for determining and reporting the contaminant sensitivity (flow degradation) of a fluid power hydraulic positive fixed displacement pump due to wear caused by silica contaminants using classified AC Fine Test Dust (ACFTD).'] The test is conducted under constant conditions of speed, pressure and temperature. System clean-up between successive injections of ACFTD during the test is not permitted. The test data will assist in establishing filtration requirements for the protection of a pump when installed and operated in a hydraulic circuit. This International Standard does not cover pump failure due to a) causes other than wear as measured by flow degradation; b) the presence of water and the action of oil chemistry plus water on pump wear surfaces; c) fatigue, over-pressurization and other catastrophic modes. - ISO viscosity Qualifying and controlling cleaning methods. - an operating system.
