ISO 16276-1 is an international standard that falls under the category of corrosion protection and surface treatment. Specifically, it addresses the assessment of surface quality for steel substrates after surface preparation (such as blast cleaning).
New inspectors often panic when they see bare steel (Surface E). However, if the required adhesion is 5 MPa and you pulled 6 MPa before the coating ripped off the steel cleanly, the result is a pass (because the required force was achieved before failure). The PDF examples clarify this nuance. pdf iso -16276-1
