    AS2129 still in use but now only covers Table D to H. Table C now obsolete, Table J to T now replaced by AS4331.1 which is a replication of ISO7500-1 which in turn is equivalent to ASME 150-2500 class ANSI B16.5. AS4331.1 and ISO 7005-1 also incorporates previous DIN PN rated flanging. AS4087 is the new standard covering Table D to H. The same drilling is specified but the PN rating system is used (PN14 to PN35) and in some cases flange thickness varies slightly. AS4087 PN14 & PN16 are the same drilling as AS2129 Table D. AS4087 PN21 is the same drilling and rating as AS2129 Table F. AS4087. AS4087 PN14 & PN16 is the same drilling as AS2129 Table D. AS4087 PN21 is the same rating and drilling as AS2129 Table F and PN35 is the same drilling as Table H. AS4087 specifies raised face in Ductile Iron PN16 & PN35 and flat face in Grey Cast Iron PN14, PN21, PN35. Click here to view full AS4087 flanging dimensions.

    ② British metric standard BS4504 is now obsolete and replaced by EN1092-1 edition 09-2008 for steel flanges which also incorporates DIN2501 standard. EN1092-1 is also published in the British standards as BS-EN1092-1. Flange drillings in EN1092-1 are generally the same as BS4504 but EN1092-1 covers a wider range.

    EN1092-1 is for steel flanges, EN1092-2 is for Iron flanges, EN1092-3 is for Copper Alloy flanges, EN1092-4 is for Aluminium flanges. Regarding EN1092-2 Iron flanges, these figures are for integral flanges on valves, etc. Cast (Grey) Iron thicknesses are shown in Cast Iron column. EN1092-2 specifies a thinner flange thickness for Ductile Iron in larger sizes which is shown in the Ductile Iron column. For full EN1092-1 table Click here EN1092-1 is for steel flanges.

    Refer EN1092-3 copper alloy, EN1092-4 aluminium alloy.

    ISO7005-1 & ISO 7005-2 (which AS4331.1 mirrors) replaces DIN 2501 & DIN 2533 and BS4504 PN6 to 40. ISO7005-1 & 7005-2 PN6 to 40 is the same as EN1092-1 (note some flanges thicknesses vary slightly) but also incorporates ANSI flanging redesignated as PN20, PN50, PN110, PN150, PN260, PN420. ISO7005-1/AS4331.1 is steel flanges, ISO7005-2/AS4331.2 is iron flanges, ISO7005-3/AS4331.3 is copper alloy flanges. AS4331.1 is a reproduction of ISO7005-1, AS4331.2 is a reproduction of ISO7005-2, AS4331.3 is a reproduction of ISO7005-3.

    * Varies according to flange type (thickness includes raised face height where applicable) refer to standard
