This British Standard specifies requirements for fluid resistant ethylene–propylene rubber material with excellent ozone resistance properties intended for the production of items such as sheet, mouldings and certain extrusions, for use in sealing operations where low compression set is of prime importance while in contact with phosphate ester hydraulic fluids over a temperature range of –60 °C to 100 °C, or with silicone hydraulic fluids over a temperature range of –60 °C to 130 °C1).

For applications in contact with air, the material may be suitable for use over a temperature range of –60 °C to 120 °C.

NOTE 1 Material in contact with phosphate ester hydraulic fluids may be exposed to temperatures up to 130 °C for intermittent periods, and material in contact with silicone hydraulic fluids exposed to temperatures up to 160 °C for intermittent periods.

NOTE 2 Materials and products manufactured from this material are unsuitable for use in contact with fuels, mineral oil based and di-ester oils and silicate fluids or greases derived from them.

NOTE 3 Further information on the suitability of fluid resistant ethylene–propylene rubber for design applications can be found in SBAC Technical Specification No. 97 [1].

NOTE 4 Marking BS F 156:2006 on or in relation to a product represents a manufacturer’s declaration of conformity, i.e. a claim by or on behalf of the manufacturer that the product meets the requirements of the standard. The accuracy of the claim is solely the claimant’s responsibility. Such a declaration is not to be confused with third party certification of conformity.

1) Ethylene–propylene rubber products, when properly stored at room temperature and in the absence of hostile environments, deteriorate very slowly and, for most practical purposes, the storage life may be considered indefinite. However, the rate of deterioration increases markedly with increase in temperature and the service life of the rubber therefore depends upon the operational temperature. Conversely, the maximum temperature at which the rubber may be used depends on the useful life required.
