13、 Copy, (c) BSI BSI 20061 BS F 154:2006 1 Scope This British Standard specifies requirements for fluorosilicone rubber material possessing excellent ozone resistance properties intended for the production of items such as sheet, mouldings and certain extrusions for use in sealing applications in cont
14、act with petroleum based fuels, hydraulic fluids and lubricants and with silicone and certain ester based 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
15、with BS EN 3207. NOTE 1 Material and products manufactured from this specification, when used in air, may be 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 in
16、formation on the suitability of fluorosilicone rubber for design applications can be found in SBAC Technical Specification No. 97 1. NOTE 4 Marking BS F 154:2006 on or in relation to a product represents a manufacturers declaration of conformity, i.e. a claim by or on behalf of the manufacturer that
17、 the product meets the requirements of the standard. The accuracy of the claim is solely the claimants responsibility. Such a declaration is not to be confused with third party certification of conformity. 2 Normative references The following referenced documents are indispensable for the applicatio
18、n of this document. For dated references, only the reference cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

21、wly 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
22、the rubber may be used depends upon the useful life required.

29、cation and grades Material shall be supplied in three nominal hardness grades: Grade 60; Grade 70; Grade 80. Material or products manufactured to a nominal hardness grades other than those specified shall, with the exception of hardness, meet all the requirements of this specification specified for
30、the grade embracing the nominal hardness value. Tolerances, if required tighter than those specified within this specification, shall not be tighter than 3. NOTE For example, where a hardness of 65 is specified, the requirements of Grade 60 apply as the value of 65 lies within the 56 to 65 hardness
31、range of Grade 60. 5 Properties Material manufactured in accordance with Annex A shall meet the requirements specified within Tables 1, 2, 3, 4 and 5. The first production batch and every subsequent 10th batch of material shall be fully tested in accordance with material standard line numbers specif
32、ied in Tables 1, 2, 3, 4 and 5. All other batches of material shall be tested in accordance with: material standard line numbers 1, 3 and 15 of Table 1; material standard line number 3 of Table 5.
