Standard Specification for Phosphate Ester Based Fluids for Turbine Lubrication and Steam Turbine Electro-Hydraulic Control (EHC) Applications

Fecha:
2018-03-28 /Active
Abstract:

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.

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 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.5 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.
