24、BSI 1997 Introduction Dimensions for the internal diameter of gaskets are a compromise between all requirements of prEN 1092-1, prEN 1092-2, prEN 1092-3 and prEN 1092-4 so that a single value is given for each gasket size. WARNING. Gaskets made to this standard may contain asbestos. Materials contai
25、ning asbestos may be subject to legislation that requires precautions to be taken when handling them to ensure that they do not constitute a hazard to health (see annex B). Attention is drawn to the relevant EEC directives. 1 Scope This European Standard specifies the dimensions and marking of non-m
26、etallic flat gaskets, with or without inserts, for use with flanges complying with prEN 1092-1, prEN 1092-2, prEN 1092-3 and prEN 1092-4, and pipes and fittings complying with EN 545, EN 598 and EN 969 up to and including PN 63 and up to and including DN 4000. NOTE 1. Dimensions of other types of ga
27、skets for use with flanges complying with prEN 1092-1, prEN 1092-2, prEN 1092-3 and prEN 1092-4 are given in EN 1514-2, EN 1514-3 and EN 1514-4. NOTE 2. Annex A lists information that should be supplied by the purchaser when ordering gaskets and annex C lists typical materials for the manufacture of
28、 non-metallic flat gaskets. NOTE 3. Clause 9 gives inside diameters of gaskets specifically for use with flanges complying with EN 545, EN 598 and EN 969, and also with ISO 2531. NOTE 4. This standard does not provide dimensions to suit PN 100 flanges, as gaskets covered by this standard are not nec
29、essarily intended for such applications. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated refer

38、nufactured in a single material or combination of materials and shall be: a) single flat sheet; or b) laminated ply; or c) moulded. NOTE 1. Examples of typical materials are given in annex C. NOTE 2. The selection of the gasket material should take into account the fluid, the operating conditions, t
39、he 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 annex A). NOTE 3. The purchaser should indicate on his
40、enquiry and/or order if gaskets are to be used with water intended for human consumption (see annex A). It shall be noted 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) type
41、 FF gasket, for use with type A (flat face) or type B (raised face) flange facings (see figures 1a and 2a); b) type IBC gasket, for use with type A (flat face) or type B (raised face) flange facings (see figures 1b and 2b); c) type TG gasket, for use with type C/D (tongue/groove) flange facings (see
42、 figures 1c and 2b); d) type SR gasket, for use with type E/F (spigot/recess) flange facings (see figures 1d and 2b). NOTE 1. The types of flange facings are specified in prEN 1092-1, prEN 1092-2, prEN 1092-3 and prEN 1092-4, and, for information, the facings are shown in figure 3. NOTE 2. The selec
43、tion of gasket type should take into account the fluid, the operating conditions, the properties of the gasket materials, the type and surface finish of the flange facing and the flange bolt loading. It is recommended that selection of gasket type for any particular application is made in consultati
44、on with the gasket supplier (see annex A). NOTE 3. Only type FF and type IBC gaskets are suitable for use with flanges on pipes and fittings complying with EN 545, EN 598 and EN 969. NOTE 4. Gaskets of types described in 6a, b, c and d and having an outside diameter greater than 1500 mm may be avail
45、able only in segmental form.
