1 Scope This standard gives the definition of nominal size when applied to components of a pipework system, and specifies the nominal size series used for pipework components. This standard is applicable to pipework components whose nominal size is designated by DN. 2 Terms and definitions For the purposes of this document, the following term and definition apply. 2.1 nominal size an alphanumeric designation of size for components of a pipework system, which is used for reference purposes and comprises the letters DN followed by a dimensionless whole number Notes: 1 This dimensionless number is directly related to the physical size (in mm), of the bore or outside diameter of the end connections. 2 The number following the letters DN does not represent a measurable value and shall not be used for calculation purposes except where specified in the relevant standard.
