22、ased fluids over the temperature range 60 C to 150 C1).For applications in air the material is suitable over the temperature range 60 C to 180 C.This material standard is to be used in conjunction with BS EN 3207.NOTE 1 Material and products manufactured from this specification, when used in air, ma

23、ybe used up to 200 C for short intermittent periods.NOTE 2 Material and products manufactures from this specification are not intended for use in contact with phosphate esters.NOTE 3 Further information on the suitability of fluorosiliconerubber for design applications can be found in SBAC Technical

24、 Specification No. 97 1.NOTE 4 Marking BS F 154:2006 on or in relation to a product representsa manufacturers declaration of conformity, i.e. a claim by or on behalf ofthe manufacturer that the product meets the requirements of the standard. The accuracy of the claim is solely the claimants responsi

28、oducts Part 1: Dimensional tolerances1)Fluorosilicone 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 lifemay be considered indefinite. However, therate of deterioration increa

29、ses markedly with increasein 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 upon the useful life required.BS F 154:2006 The British Standards Institution 2014 1BS F 154:2006
