Description: DN (nominal width) is an alphanumeric description of the size for components in a pipe system as a reference, in contrast to components that are defined by an external diameter or by a thread size. It comprises the letters DN followed by dimensionless whole number, which is in indirect correlation with physical size of the bore or external diameter of the connections (measured in millimeters). NOTE 1: the nominal width DN cannot be used for measurements or calculations. NOTE 2: Some older international norms describe the nominal width as a nominal diameter, but both terms are identical for this norm. NOTE 3: the nominal width is defined is alignment with ISO 6708. in accordance with EN 60534-1; Name: Nominal width of the muffs, A2
