Cobus,
There isn't one.
I posted this recently regarding ASME IX and BS/EN/ISO and it would also be applicable to AWS D1.1
If you want to qualify a welding procedure and/or qualify welders to ASME IX it is all contained in one book - a very big book but everything you need is there.
If you want to qualify anything to EN ISO then be well prepared.
ISO 9606-1 (this is only 1 of 5 parts) has 14 x standards that are deemed "indispensible"for working with this code/standard.
So that is 15 x documents required for welder qualification.
Then BS EN 15614 for your welding procedures has 24 x referenced standards included but no mention of "indispensible".
So that is 25 x documents required for welding procedure qualification.
So with my basic maths it looks like EN ISO requires 40 x documents / codes / standards to do what ASME IX does in one.
