It comprises the letters DN followed by a dimensionless whole number
33、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
34、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.
