5.2 This test method is limited to evaluating lower levels of adhesion (see 1.3).The intra- and inter-laboratory precision of this test method is similar to other test methods for coated substrates (for example, Test Method D2370 and Test Method D4060), and is insensitive to all but large differences in adhesion.Limiting the range of rankings from 0 to 5 reflects the inability of this test dolly preparation for pull off adhesion testingASTM D4541 and ISO 4624 - DFD® InstrumentsPull-off adhesion testing of paint, varnish and other coatings and films with the PAT adhesion tester and the DFD® method. ASTM D4541 and ISO 4624 (EN 24624) ISO 4624 paints and varnish pull off test for adhesion both define the method and procedures for carrying out pull-off adhesion testing of paints, varnishes and other coatings.ASTM D4541-17 - Pull-Off Strength of Coatings Test - ANSI Sep 25, 2017 · The standard test method covered in ASTM D4541-17 Standard Test Method for Pull-Off Strength of Coatings Using Portable Adhesion Testers is used for evaluating the pull-off strength (otherwise known as adhesion) of a coating system from metal substrates. The Pull-off strength determined by this procedure is a performance property, and it may be referenced in specifications.

ASTM D4541-17 - Pull-Off Strength of Coatings Test - ANSI

Sep 25, 2017 · The pull-off test is performed by securing a loading fixture, such as a dolly or stud, to the surface of the coating being tested with a glue. A testing apparatus is attached to the loading fixture and aligned to apply tension to the test surface.ATM20A - PosiTest Pull-Off Adhesion Tester for 20mm dolly preparation for pull off adhesion testingFor smaller pipe diameters, depending on the expected pull-off strength of the coating, it may be possible to use a 10 mm or 14 mm dolly. External diameters can be decreased to as low as 50 mm and 100 mm, for the 10 mm and 14 mm dollies, respectively. Manufacturers do do not provide or support the use of curved dollies for adhesion testing.Data Sheet / Instructions - ERICHSENPart 1: Pull-off testing.

This articles focuses on the dolly preparation process and its importance in maximizing repeatability by dolly preparation for pull off adhesion testing Pull Off Tester Theory of Operation. Portable pull-off adhesion testers measure the force required to pull a specified dolly preparation for pull off adhesion testing Dolly Gardco :: Positest Pull-Off Adhesion TestTo obtain more repeatable and meaningful adhesion measurements, it is imperative that the pulling force applied to the test dolly is uniformly distributed over the surface being tested. The Self-Aligning Dolly enables uniform distribution of the pulling force over the surface being tested, preventing a one-sided pull-off.

Measurement of Adhesion Strength

When higher pull-off strengths are required, the PosiTest AT can be used with custom sized dollies to attain higher pull-off strengths. For example, a 14 mm dolly provides double the pull-off strength of a 20 mm dolly. With 14 mm dollies the PosiTest AT can attain pull-off strengths as high as 6000 psi (40 MPa). Similarly, a 10 mm dolly dolly preparation for pull off adhesion testingPULL-OFF ADHESION TESTING OF COATINGS IMPROVE The tensile pull-off method for adhesion testing, as outlined in ASTM D 4541 and similarly in BS EN ISO 4624, involves gluing a test dolly to the coated surface and then pulling the dolly by exerting a force perpendicular to the surface in an effort to remove the dolly with the coating fromPosiTest Pull-Off Adhesion Testertensile pull-off force that it can bear before detaching.
