5、COPE 1.1 Form This specification covers a neopentyl polyol ester fluid. 1.2 Application This fluid has been used typically 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 re
6、quired by an applicable 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. 1.3 Safety - Hazardous Materials While the materials, methods, applications, and proc
7、esses 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 a
8、nd to take necessary precautionary measures to ensure the health and safety of all personnel involved. 2. APPLICABLE DOCUMENTS The issue of the following documents in effect on the date of the purchase order forms a part of this specification to the extent specified herein. The supplier may work to
9、a subsequent revision of a document unless a specific document issue is specified. When the referenced document has been cancelled and no superseding document has been specified, the last published issue of that document shall apply. 2.1 SAE Publications Available from SAE International, 400 Commonw
