This European Standard specifies the construction, dimensions and marking of covered serrated metal gaskets for use with flanges complying with EN 1092-1 for PN 10, PN 16, PN 25, PN 40, PN 63 and PN 100 up to and including DN 3000. This document does not extend to covered serrated metal based heat exchanger gaskets with pass bars or large vessel gaskets but, in the lack of a dedicated document for such gaskets, the principles set down can be applied to them.NOTE 1Dimensions of other types of gaskets for use with flanges to EN 1092-1, EN 1092-2, prEN 1092-3 and EN 1092-4 are given in EN 1514-1, EN 1514-2, EN 1514-3, EN 1514-4, prEN 1514-7 and prEN 1514-8.NOTE 2Annex A lists information that should be supplied by the purchaser when ordering gaskets in circumstances where the choice of the gasket materials appropriate to the service is left to the supplier.
