1 Scope
1.1 This standard covers the evaluation of the oxidation stability of inhibited steam turbine oils in the presence of oxygen, water, and copper and iron metals at an elevated temperature. This test method is limited to a maximum testing time of 10000h. This test method is also used for testing other oils, such as hydraulic oils and circulating oils having a specific gravity less than that of water and containing rust and oxidation inhibitors.
1.2 This standard adopts SI units.
1.3 This standard is involved in some materials, operations and equipments with hazard, but does not purport to address all of the safety concerns. Therefore, it is the responsibility of the user of this standard to establish appropriate safety and protective measures and determine the applicability of management system prior to use.
2 Normative References
