This European Standard specifies the construction, dimensions and marking of covered serrated metal gaskets for use with flanges complying with prEN 1759-1 for Class 150, Class 300, Class 600, Class 900, Class 1500 and Class 2500 up to and including NPS 24. This document does not extend to serrated covered 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 prEN 1759-1, prEN 1759-3 and prEN 1759-4 are given in EN 12560-1, EN 12560-2, EN 12560-3, EN 12560-4, EN 12560- 5 and prEN 12560-7.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.
