ASTM D4293-22 - 1.12.2022
 
1. Scope

1.1?This specification covers the minimum requirements for phosphate ester-based fluids for turbine lubricants and electro-hydraulic control fluids, as delivered.

1.2?The use of this type of fluid is restricted to turbine systems designed or modified to accommodate phosphate ester fluids.

1.3?This standard does not cover the minimum requirements for in-service phosphate ester fluids for the turbine electro-hydraulic control (EHC) fluid. These requirements are provided in Guide D8323.

1.4?The values stated in SI units are to be regarded as standard. For convenience, other units of measurement are provided in brackets.

1.5?This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.6?This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
