Specific pipe is identified by pipe diameter and another non-dimensional number for wall thickness referred to as the Schedule (Sched. or Sch., for example – "2-inch diameter pipe, Schedule 40").

ISO 6708 defines the nominal size - DN - as an alphanumeric designation of size 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 (ID) or outside diameter (OD) of the end connections.

DN gives a rough estimate of the internal diameter of a pipe. It doesn’t directly correlate to the actual OD or ID but is close to ID for larger pipes. Not directly related to pipe diameter but is an indicator of pressure handling capability.
