True or false: ASTM has one pull-off adhesion test of coatings on concrete, and a separate one for coatings on metal substrates.


What is another name for a tensile adhesion test of coatings?


True or false: The adhesion of a coating to a steel substrate depends entirely upon the mechanical attachment or hooking of the coating to the profile of the steel.


True or false: ASTM has separate test methods for steel and concrete substrates in determining the pull-off adhesion of coatings.


True or false: Portable pull-off adhesion testers include ones that operate by application of mechanical or hydraulic or pneumatic force.


True or false: ASTM D 4541, Standard Test Method for Pull-Off Strength of Coatings Using Portable Adhesion Testers, requires a score around the loading fixture when the film thickness of the coating exceeds 20 mils.
