specifies procedures for assessing the adhesion and cohesion of protective paint coatings on steel structures using pull-off testing (generally per ISO 4624 or ASTM D4541). Its unique value lies in providing acceptance criteria specifically for corrosion protection systems on structural steel—something earlier standards avoided.

It is not just about how many MPa you pull—it’s about where the coating breaks and whether that failure mode is tolerable for long-term corrosion protection. specifies procedures for assessing the adhesion and cohesion
