Form This specification covers a silicone rubber material that can be used to manufacture product in the form of sheet@ strip@ tubing@ molded shapes@ and extrusions. This specification should not be used to address products such as O-rings@ compression seals@ O-ring cord@ and molded-inplace gaskets. For these applications AMS specifications in the AMS7XXX series should be used. Application These products have been used typically for parts required to operate or seal from -130 to +401 ??(-90 to +205 ??@ compounded especially for high strength@ but usage is not limited to such applications. Silicone elastomer is resistant to deterioration by weathering and aircraft piston engine oil and remains flexible over the temperature range noted. This rubber is not normally suitable for use in contact with gasoline or aromatic fuels and low-aniline-point petroleum-base fluids due to excessive swelling of the elastomer. Terms / Definitions MATERIAL The mixed rubber compound used to manufacture product. PRODUCT The ??end product' being supplied to the contract/purchase order originator@ usually in the form(s) specified in 1.1 above. LOT Shall be all products from the same batch of compound processed in one continuous run and submitted for inspection at one time. The material batch size allowed to form any single inspection lot of product shall not exceed 500 pounds (227 kg). BATCH Shall be the quantity of compound run through a mill or mixer at one time. Note: Smaller batches of mixed compound may be formed into a larger batch by utilizing a crossblending process that insures the homogenous nature of the newly formed larger batch. When utilizing this process all ingredient traceability of the smaller batches must be maintained and directly tied to the resulting larger batch. Only the resulting larger batch needs to be subject to Batch Acceptance Testing requirements of this specification.) MIXER The vendor in the supply chain that performs the actual mixing of the Rubber Compound utilized to produce product. MASTERBATCH A batch of compound that has been mixed to completely incorporate most of thecompound ingredients@ omitting the active chemicals that constitute the cure system. Typically for silicone compounds this includes catalysts and color pigments. MATERIAL REWORK Minor adjustments made to the existing ingredient content levels of a compound recipe@ while remaining within the tolerance limits specified in the recipe@ which may enhance physical properties or processability performance@ yet still maintain the original compound identity. 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.
