Gaskets made to this standard maycontain asbestos. Materials containing asbestos may besubject to legislation that requires precautions to betaken when handling them to ensure that they do notconstitute a hazard to health (see annex B). Attentionis drawn to the relevant EEC directives.1 ScopeThis European Standard specifies the dimensions andmarking of non-metallic flat gaskets, with or withoutinserts, for use with flanges complying withprEN 1092-1, prEN 1092-2, prEN 1092-3 andprEN 1092-4, and pipes and fittings complying withEN 545, EN 598 and EN 969 up to and including PN 63and up to and including DN 4000.NOTE 1. Dimensions of other types of gaskets for use withflanges complying with prEN 1092-1, prEN 1092-2, prEN 1092-3 andprEN 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 thepurchaser when ordering gaskets and annex C lists typicalmaterials for the manufacture of non-metallic flat gaskets.NOTE 3. Clause 9 gives inside diameters of gaskets specifically foruse with flanges complying with EN 545, EN 598 and EN 969, andalso with ISO 2531.NOTE 4. This standard does not provide dimensions to suitPN 100 flanges, as gaskets covered by this standard are notnecessarily intended for such applications.2 Normative referencesThis European Standard incorporates by dated orundated reference, provisions from other publications.These normative references are cited at theappropriate places in the text and the publications arelisted hereafter.

Examples of typical materials are given in annex C.NOTE 2. The selection of the gasket material should take intoaccount the fluid, the operating conditions, the properties ofthe gasket material, the type and surface finish of the flangefacing and the flange bolt loading. It is recommended thatselection of gaskets for any particular application is made inconsultation with the gasket supplier (see annex A).NOTE 3. The purchaser should indicate on his enquiry and/ororder if gaskets are to be used with water intended for humanconsumption (see annex A). It shall be noted that the nationalregulations of both the country of origin and the country of usemay be considered relevant.6 Gasket typesGaskets shall be one of the following types:a) type FF gasket, for use with type A (flat face) ortype B (raised face) flange facings (see figures 1aand 2a);b) type IBC gasket, for use with type A (flat face) ortype B (raised face) flange facings (see figures 1band 2b);c) type TG gasket, for use with type C/D(tongue/groove) flange facings (see figures 1cand 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 inprEN 1092-1, prEN 1092-2, prEN 1092-3 and prEN 1092-4, and,for information, the facings are shown in figure 3.NOTE 2.
