Defines dimensions and marking of non-metallic flat gaskets, with or without inserts, to be used with flanges, pipes and fittings complying with relevant standards.

This European Standard specifies the dimensions and marking of non-metallic 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 gaskets 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 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 necessarily intended for such applications.
