5、vised 2009-11 Superseding AMS3260B Ethylene-Propylene-Diene (EPDM) Rubber General Purpose 45 - 55 RATIONALE AMS3260C is a Five Year Review and update of this specification. 1. SCOPE 1.1 Form This specification covers an ethylene propylene (EPDM) rubber in the form of sheet, strip, tubing, extrusions
6、, and molded shapes. 1.2 Application This products has been used typically for parts, such as door seals, low-pressure gaskets, dust covers, and shock absorption devices, requiring resistance to weathering, phosphate ester base hydraulic fluids, and polar solvents such as steam, water, and ketones,
7、but usage is not limited to such applications. This material has fair resistance to all materials listed. Where better resistance to a particular fluid is required, use an AMS for the material compounded specifically for good resistance to that fluid. 1.3 Safety-Hazardous Materials While the materia
8、ls, 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 prop
9、er use of any hazardous materials and 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 specifie
10、d herein. The supplier may work to 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. SAE AMS3260C Page 2 of 6 2.1 SA
