BS 288-3 has been withdrawn and replaced with BSEN ISO 15614-1:2004

There's a lot of detail in these standards and I dont have the time to list them all.

BS15614 is a lot closer to the requirements of ASME IX than BS 2898 part 3 ever was. There are still some fundamental differences in the range of qualifications however particularly with dimensions.

I'm not familar enough with the welder performance requirements of ASME IX and a comparison with EN 287 but my limited knowledge would say that these are very similar indeed.

EN 288-2 details what is required in a WPS but doesnt cover as much ground as ASME IX (its only 5 pages long!!)

The concept of essential nonesential and supplementary variables is dealt with much more comprehensively (and restrictively) in ASME IX.

I think the simple answer is maybe ;)

Generally speaking, if you have qualified a WPS to ASME IX it will cover many of the aspects of the qualification process in the EN standards, but the range of approval on dimensions is more generous in ASME IX.

If this is for a specific client that requires EN approval then it might be worth asking if they would accept ASME qualified procedures in lieu of the EN procedures. Its really going to depend on the component, the code and the client.
