Dull Chisel Test
Gentlemen, we are doing some TSA for onsite field welds, having previously coated the spools. As this is only a small area the QC requirments are lowered (we must use same equipment / applicators etc as per the spool coatings.)
One of the clients suggestions is that we use a "Dull chisel test" to check for adhesion on the field welds, rather than doing conventional test plates and using an adhesion tester. While I can use a hammer and "dull chisel" as poorly as anyone else, does anyone have any additional documentation / reference material or standards?
