Note 2 to entry: Components intended for use for both code U and code D application areas are marked UD. Note 3 to entry: Other application area codes B and BD not covered by this standard are defined elsewhere, e.g. in EN 1329-1 [2]. 3.2 nominal size DN numerical designation of the size of a component, other than a component designated by thread size,which is approximately equal to the manufacturing dimension, in millimetres (mm)BS EN 1401-1 pdf download.
