Introduction
Dimensions for the internal diameter of gaskets are a compromise between all requirements of EN 1759-
1, EN 1759-3 and EN 1759-4 so that a single value is given for each gasket size.
1 Scope
This document specifies the dimensions, types, designation and marking of non-metallic flat gaskets, with
or without inserts, for flanges in accordance with EN 1759-1, EN 1759-3 and EN 1759-4, for Class 150,
Class 300, Class 600 and Class 900 for nominal sizes DN 15 to DN 600. In addition, this document also
gives guidance on typical materials used and how they should be marked.

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.

NPS
alphanumeric designation of size for components of a pipework system, which is used for reference
purposes and is comprised of, for the purpose of Class designated flanges according to this document, the
letters NPS followed by a dimensionless number which is indirectly related to the physical size of the
bore or outside diameter of the end connections
