Introduction
Dimensions for the internal diameter of gaskets are a compromise between all requirements of
EN 1092-1, EN 1092-2, EN 1092-3, and EN 1092-4 so that a single value is given for each gasket size.
1 Scope
This document specifies non-metallic flat gaskets, with or without inserts, for use with flanges in
accordance with EN 1092-1, EN 1092-2, EN 1092-3 and EN 1092-4, and pipes and fittings in accordance
with EN 545, EN 598, and EN 969, for pressure application up to and including PN 63 values and
dimensions up to and including DN 4000. In addition, this document also gives guidance on typical
materials used and how they should be marked.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
ISO and IEC maintain terminological databases for use in standardization at the following addresses:
— IEC Electropedia: available at https://www.electropedia.org/
— ISO Online browsing platform: available at https://www.iso.org/obp
3.1
DN
alphanumeric designation of size for components of a pipework system, which is used for reference
purposes, and is comprised of the letters DN followed by a dimensionless whole number which is
indirectly related to the physical size, in millimeters, of the bore or outside diameter of the end
connections
Note 1 to entry: The number following the letters DN does not represent a measurable value and is not used for
calculation purposes except where specified in the relevant standard.
[SOURCE: EN ISO 6708:1995, 2.1, modified – definition made into one statement, recommendation
removed from note 1 to entry]
3.2
PN
alphanumeric designation used for reference purposes related to a combination of mechanical and
dimensional characteristics for a component of a pipework system, and is comprised of the letters PN
followed by a dimensionless number
Note 1 to entry: The number following the letters PN does not represent a measurable value and is not used for
calculation purpose except where specified in the relevant standard.
Note 2 to entry: The designation PN is not meaningful unless it is related to the relevant component standard
number.
Note 3 to entry: The maximum allowable pressure of a pipework component depends on the PN number, the
material and design of the component, its maximum allowable temperature, etc. The relevant European
Component standards include tables of specified pressure/temperature ratings of, in minimum, include rules how
to determine pressure/temperature ratings.
Note 4 to entry: It is intended that all components with the same PN and DN designations have the same mating
dimensions for compatible flange types.
