I distinguish between raw material and 'other' material as material not purchased to a part number or stuff that does not require a first article per AS9102.
AS9102 requires raw material to be listed seperately on the bottom of form 2. Whereas purchased items are listed on form 1 and are subject totheir own first articles as applicable.
Therefore, forgings castings, and other 'processed' raw material is not raw material and (by my definition) not subject to raw material testing requirements on the purchaser.
The requirement should be imposed on the 'processor' of the raw material.
And remember " There is no finish line"
