This European Standard specifies the construction, dimensions and marking of covered serrated metal jacketed gaskets for use with flanges complying with EN 1092-1 for PN 2,5, PN 6, PN 10, PN 16, PN 25, PN 40, PN 63 and PN 100 up to and including DN 900.This European Standard does not extend to covered metal jacketed 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 may be applied to them.NOTE 1Dimensions of other types of gaskets for use with flanges to EN 1092-1, EN 1092-2, EN 1092-3 and EN 1092-4 are given in EN 1514-1, EN 1514-2, EN 1514-3, EN 1514-4, EN 1514-6 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.
