Omfang

This specification covers a silicone (VMQ) rubber in the form of molded rings. These rings have been used typically as sealing rings for service from -65 to +260 °C (-85 to +500 °F) in contact with air, but usage is not limited to such applications. The cross-section of such rings is usually not over 0.275 inch (6.98 mm) in diameter or thickness. Form This specification covers a vinyl-methyl silicone (VMQ) rubber in the form of molded rings, compression seals, O-ring cord, and molded-in-place gaskets for aeronautical and aerospace applications. For sheet, strip, tubing, extrusions, and molded shapes, use the AMS3304 or AMS3305 specifications, which are intended for that use. Application This material has resistance to hot air but generally poor resistance to fuels and lubricants, but usage is not limited to such applications. This material has a typical service temperature range of -85 to 500 °F (-65 to 260 °C). The service temperature range of the material is a general temperature range, but the presence of particular fluids and specific design requirements may modify this range. Each application should be considered separately. It is the responsibility of the user to determine that this specification is appropriate for the environments (temperature range, fluids exposure, etc.) in which it is sought to be used. Order of Precedence Nothing in this document, however, supersedes applicable laws and regulations unless a specific exemption has been obtained. This specification is in addition to and in no way limiting, superseding, or abrogating any contractual obligation as required by the applicable procurement document. In the event of conflict in requirements, the order of precedence shall be: 1. Procurement document or contractual agreement and all statutory and regulatory requirements (excluding this document). 2. Applicable purchaser’s drawing or AS9385 or AS9386 parts standards. 3. Specification referenced on the drawing. 4. This document. 5. All specifications referenced in this document. 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.
