29、ordance with the ranges specified in Tables 1, 2 and 3. 4.3 Gasket types Gasket types as defined in clause 6 and illustrated in Figures 1 and 2 shall be designated as: Type FF; Type IBC; Type TG; Type SR. 4.4 Information to be supplied by the purchaser The following information shall be supplied by
30、the purchaser when ordering gaskets: a) the number and part of this European Standard, i.e. EN 12560-1; b) gasket type designation (see 4.3); c) nominal size (see Tables 2 or 3, as appropriate); d) Class designation (see Tables 2 or 3, as appropriate); e) thickness (see 8.1); f) material(s) (see cla
31、use 5). Additional information that should be supplied by the purchaser: g) expected operating conditions for which the gasket will be used and whether the gasket is required for use with water intended for human consumption (see clause 5).Page 7 EN 12560-1:2001 BSI 03-2001 NOTE: Before ordering a g
32、asket it is recommended that the selection of the gasket type, material and thickness should be made in consultation with the gasket supplier. The selection of gasket material type and thickness should take into account the fluid, the operating conditions, the properties of the gasket material, the
33、type and surface finish of the flange facing and the flange bolt loading. EXAMPLE: A gasket according to EN 12560-1, full face type (type FF), of nominal size DN 100, Class 150, 2 mm thickness in expanded graphite, shall be designated as follows: Gasket EN 12560-1 FF DN 100 Class 150 2 mm expanded g

NOTE 1: The selection of the gasket material should take into account the fluid,
35、 the operating conditions, the properties of the gasket material, the type and surface finish of the flange facing and the flange bolt loading. It is recommended that selection of gaskets for any particular application is made in consultation with the gasket supplier (see 4.4). Where gaskets come, o
36、r are likely to come, into contact with water intended for human consumption, the materials shall comply with relevant national regulations. NOTE 2: The purchaser should indicate on the enquiry and/or order if gaskets are to be used with water intended for human consumption (see 4.4). It should be n
37、oted that the national regulations of both the country of origin and the country of use may be considered relevant. 6 Gasket types Gaskets shall be one of the following types: a) Full face type gasket (designation: type FF) for use with type A (flat face) or type B (raised face) flange facings see F
