As per my knowledge there is no specific standard saying
this, usally it is demanded by Company specification.
So you can check in your CPY reference doc, If not found
do not hesitate to ask your cpy to mention it in the reference
doc.
Also It's company's responsibility to decide whether NDT
should be done after PWHT or not ?

Thanks a lot
