2 Normative references

The following documents, in whole or in part, are normatively referenced in this document and are

indispensable for its application. For dated references, only the edition cited applies. For undated

references, the latest edition of the referenced document (including any amendments) applies.

EN 1333, Flanges and their joints - Pipework components - Definition and selection of PN

EN ISO 6708, Pipework components - Definition and selection of DN (nominal size) (ISO 6708)

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1

alphanumeric designation of size for components of a pipework system, which is used for reference

purposes. It comprises the letters DN followed by a dimensionless whole number which is indirectly

related to the physical size, in millimetres, 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 should not be

used for calculation purposes except where specified in the relevant standard.

Note 2 to entry: In those standards which use the DN designation system, any relationship between DN and

component dimensions should be given (e.g. DN/OD or DN/ID).

3.2

alphanumeric designation used for reference purposes related to a combination of mechanical and

dimensional characteristics of a component of a pipework system. It comprises 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 should not be

used for calculation purposes 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 or, in minimum, include rules how

to determine pressure/temperature ratings.
