STD*BSI BS EN L25bO-L-ENGL 2001 D 1b24bb7 0701759 TbO Page 7 EN 12560-1 12001 NOTE: Before ordering a gasket it is recommended that the selection of the gasket type, material and thickness should be made in consulta
34、tion 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 type and surface finish of the flange facing and the flange bolt loading. EXAMPLE: A gasket according to EN 1256
35、0-1, 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 graphite. 5 Gasket designs and materials Gaskets shall be manufactured in a single material or combinat
36、ion of materials and shall be one of the following designs: a) single flat sheet; or b) laminated ply; or c) moulded. NOTE 1: The selection of the gasket material should take into account the fluid, the operating conditions, the properties of the gasket material, the type and surface finish of the f
37、lange 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, or are likely to come, into contact with water intended for human consumption, the materials shall comp
38、ly with relevant national regulations. NOTE 2: The purchaser should indicate on the enquiry andlor order if gaskets are to be used with water intended for human consumption (see 4.4). It should be noted that the national regulations of both the country of origin and the country of use may be conside
39、red relevant. 6 Gaskettypes 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 Figures 1 a) and 2 a); b) Inside bolt circle type gasket (designation: type IBC) for use with type A (fl
40、at face) or type B (raised face) flange facings see Figures 1 b), 2 b), 2 c) and 2 d); c) Tongue and groove type gasket (designation: type TG) for use with type CID (tongue/groove) flange facings see Figures 1 c) and 2 b), 2 c) and 2 d); d) Spigot and recess type gasket (designation type SR), for us
41、e with type EIF (spigotirecess) flange facings see Figures I d); 2 b), 2 c) and 2 d); NOTE 1: The types of flange facings are specified in prEN 1759-1:2000, prEN 1759-3:1994 and prEN 175941997 and for information, the facings are shown in Figure 3. NOTE 2: The selection of gasket type should take in
42、to account the fluid, the operating conditions, the properties of the gasket material, the type and surface finish of the flange facing and the flange bolt loading.
