BS F 156:2006 pdf free.Properties of fluidresistant ethylene-propylene rubber sheet, mouldings and extrusions Specification.
BS F 156 This British Standard specifies requirements for fluid resistant ethylene-propylene rubber material with excellent ozone resistanceproperties intended for the production of items such as sheet, mouldings and certain extrusions, for use in sealing operations wherelow compression set is of prime importance while in contact withphosphate ester hydraulic fluids over a temperature range of -60 Cto 100C, or with silicone hydraulic fluids over a temperature rangeof -60C to 130°C1).
For applications in contact with air, the material may be suitable for useover a temperature range of-60 C to 120 °℃.
NOTE 1 Material in contact with phosphate ester hydraulic fluids may beexposed to temperatures up to 130o C for intermittent periods, and
material in contact with silicone haydraulic fluids exposed to temperaturesup to 160 C for intermittent periods.
NOTE 2 Materials and products manufactured from this material areunswitable for use in contact with fuels, mineral oil based and di-ester oilsand silicate fluids or greases derived from them.
NOTE 3 Fwrther information on the suitability of fluid resistant
ethylene-propylene rubber for design applications can be found in SBACTechnical Specification No.97 [ 1 ].
NOTE4 Marking BS F 156:2006 on or in relation to a product representsa manufacturer’s declaration of conformity, i.e. a claim by or on behalf ofthe manufacturer that the product meets the requivements of the standard.The accuracy of the claim is solely the claimant’s responsibility.Such adeclaration is not to be confused with third party certification of
conformity.
The following referenced documents are indispensable for the application of this document. For dated references, only the referencecited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.
Ethylene-propylene rubber material and products manufactured fromthis material shall be formulated and manufactured to issue controlleddocumentation, which shall form part of the contract between
purchaser and manufacturer.
Changes to the formulation or manufacturing process shall not be madewithout due consideration being given that the modified material/product meets all the requirements of the standard.BS F 156 pdf download.
