This International Standard does not purport to address all of the safety problems associated with its use. It is the responsibility of the users of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. 1 Scope This International Standard specifies the characteristics of unused triaryl phosphate ester fluids for turbine governor controls and other hydraulic systems in electrical power stations. NOTE Fluids used in this application are classified under category TCD of ISO 6743-5:_1]. These fluids are difficult to ignite and show little tendency to propagate flame, but cannot be considered non- equipment manufacturer. Regular maintenance of these fluids is important.
