This specification covers the requirements for phosphate ester based fire resistant fluids for use in turbine lubrication. Only unused fluid is defined before it is installed in the turbine while fluids used in electrohydraulic control (EHC) systems is not. The use of this type of fluid is restricted to turbine systems that have been designed or modified to accommodate phosphate ester lubricants. Fire tests shall be performed which measure and describe the properties of the phosphate esters in response to heat and flame under controlled laboratory conditions and should not be considered or used for the description or appraisal of the fire hazard of the fluids under actual fire conditions.
This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.
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 that have been designed or modified to accommodate phosphate ester fluids.
1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.4 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 and health practices and determine the applicability of regulatory limitations prior to use.
