Introduction
This standard is related to ISO 7005-3 in respect of flanges having the same PN. The types of flanges and
their mating dimensions are identical with those flanges of the same DN and PN given in ISO 7005-3,
except that certain flange types in accordance with this standard may regularly be supplied with raised
face facings.
The mating dimensions of the flanges of this standard are compatible with PN designated flanges of
other materials in accordance with the other parts of EN 1092.
1 Scope
This document specifies requirements for circular copper alloy flanges and copper alloy collars
combined with loose steel plate flanges in PN designations from PN 6 to PN 40 and nominal sizes from

This document also specifies dimensions and tolerances, materials and their associated
pressure/temperature (p/T) ratings, flange facings and related surface finish, weld repairs, and
marking, together with information on bolting, gaskets, application/installation and approximate flange
