5、ised 2017-04 Superseding AMS3021D Fluid, Reference for Testing Di-Ester (Polyol) Resistant Material RATIONALE Revised to include the addition of a recommended substitute fluid. 1. SCOPE 1.1 Form This specification covers a neopentyl polyol ester fluid. 1.2 Application This fluid has been used typica
6、lly to evaluate the ability of elastomeric and other polymeric compounds to conform to designated requirements after immersion in the fluid at a specific temperature and time, as required by an applicable specification, and its use is limited to such applications. This fluid is not intended for oper
7、ational use in gas turbine engines (see 8.2). Each application should be considered separately. 1.3 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
