This European Standard specifies the construction, dimensions and marking of covered metal jacketed gaskets for use with flanges complying with prEN 1759-1 for Class 150, Class 300, Class 600, Class 900. Class 1 500 for sizes up to and including NPS 24, and for Class designation 2 500 up to and including NPS 12.

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 1 Dimensions of other types of gaskets for use with flanges to prEN 1759-1, EN 1759-3 and EN 1759-4 are given in EN 12560-1, EN 12560-2, EN 12560-3, EN 12560-4, EN 12560-5 and EN 12560-6.
