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 (because the required force was achieved before failure). The PDF examples clarify this nuance.

The PDF clearly states that these are minimum values. High-performance linings (epoxies for chemical storage) may require 7+ MPa. Always refer to the coating manufacturer's data sheet in conjunction with ISO 16276-1. New inspectors often panic when they see bare
