strength of hardened render-
ing and plastering mortars on
substrates

Determination of the adhesive
strength of cement based mor-
tar for indoor and outdoor.
ISO 4624 Paints and varnishes - Pull-off
test for adhesion. Supercedes

Part 207 sessment of concrete strength
by near-to surface tests
ASTM D Standard test method for pull-
4541 off strength of coatings using
portable adhesion testers

1583 tensile strength of concrete
surfaces and the bond strength
or tensile strength of concrete
repair and overlay materials by
direct tension (Pull-off method)

7234-05 off adhesion strength of coat-
ings on concrete using portable
pull-off adhesion testers
