In Australia the BS and AS flange standards are essentially the same but have been metricated. Consequently metric sizes are stated as ‘DN’ (Nominal Diameter) in mm. Equivalent imperial sizing is rounded to the nearest multiple of 25mm (for 2” and over) as below. However the actual dimensions and bore sizes have not changed. ‘NB’ (Nominal Bore) is also sometimes used when referring to valve sizes.

AS 2129 originates from BS10 and has been metricated. In some cases slightly larger bolt holes provide better clearance as metric bolts are specified in lieu of UNC bolts used by BS10. AS4087 is an update of AS2129, however AS2129 is still widely used so it has not been deleted as a standard, however, it now only covers AS table D to H.
AS4087 is the latest standard for BS table D to H, the same drilling is used but the new PN pressure rating system has been adopted. As the new pressure ratings are slightly higher the flange thicknesses have slightly increased. Also the raised face dimensions (although rarely specified, flat face is mostly used) are slightly larger. Table C, J to R, no longer exist, PN16 is the same drilling as Table D, PN21 is the same as Table E, PN35 is the same as Table H.
AS4331 covers PN2.5 to PN420 and the sizing and drilling used is a replication of ISO 7005-1 which in turn is a metricated equivalent of ASME B16.5 class 150 to 2500. ISO 7005-1 also incorporates the superceded DIN 2533 & DIN 2501 flanges which AS4331 also incorporates (also mirrored in EN1092).
