Form This specification covers a neopentyl polyol ester fluid (see 8.2) with AS5780 HPC or MIL-PRF-23699 HTS Class performance. Application This fluid has been used typically to evaluate the ability of elastomeric and other polymeric materials to conform to designated requirements after contact with@ or immersion in@ AS5780 HPC Class and MIL-PRF-23699 HTS Class oils@ at a specified time and temperature@ as required by an application specification@ and its use is limited to such applications. This fluid is not intended for operational use in gas turbine engines (see 8.2). Each application should be considered separately. Safety - Hazardous Materials While the materials@ methods@ applications@ and processes described or referenced in this specification may involve the use of hazardous materials@ this specification does not address the hazards which may be involved in such use. It is the sole responsibility of the user to ensure familiarity with the safe and proper use of any hazardous materials and to take necessary precautionary measures to ensure the health and safety of all personnel involved.
