Because the substrate and its surface preparation or lack of it have a drastic effect on the adhesion of coatings, a method to evaluate 3539-02 of a coating to different substrates or surface treatments, or of different coatings to the 2 3 1.

Procedure for A-X-CUT TAPE TEST METHOD-ASTM D

Precision and Bias 9. Flaking and detachment worse than Grade 1. The color under the transparent tape is a useful indication of when good contact has been made. Extremes in temperature or relative humidity may affect the adhesion of the tape or the coating. ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard.

For tests in the? It is reasonable to state that at the present time no test exists that can precisely assess the actual physical strength of an adhesive bond. It is of particular importance that the cutting edges be in good condition. Apparatus and Materials 5. Further, the tape test does not give an absolute value for the force required for bond rupture, but serves only as an indicator that some minimum value for bond strength was met or exceeded 7, 8.

ASTM D | Leonardo Gonçalves –

Remove an additional length at a steady that is, not jerked rate and cut a piece about 75 mm 3 in. Your asym are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters. Both concerns are well founded: There generally is difficulty, however, in relating these tests to basic adhesion phenomena. Cohesive failure within the coating? Posted in Powder Coating News Tags: Rate the adhesion in accordance with the following scale illustrated in Fig.

Key steps that directly re? When making the incisions, use the straightedge and cut through the coating to the substrate in one steady motion. The color under the tape is a useful indication of when good contact has f made. Some commercial tapes are manufactured to meet minimum standards.

A given lot may surpass these standards and thus be suitable for general market distribution; however, such a lot may be a source of serious and unexpected error in assessing adhesion. This standard has been approved for use by agencies of the Department of Defense. Standard Test Method f Extremes in temperature or relative humidity may affect the adhesion of the tape or the coating.

The intra- and inter-laboratory precision of this test method is similar to other widely-accepted tests for coated substrates for example, Test Method D and Test Method Dbut this is partly the result of it being insensitive to all but large differences in adhesion. Criteria deemed essential for a test to warrant large-scale acceptance are: Criticism of these tests arises when they are used to quantify the strength of adhesive bonding.

Smooth the tape into place by? For multicoat systems where adhesion failure may occur between or within coats, the adhesion of the coating system to the substrate is not determined. If the adhesion strength of the tape has not been determined, report the speci? Summary aastm Test Methods 3.

Applied to metals, it is economical to perform, lends itself to job site application, and most importantly, after decades of use, people feel comfortable with it. These effects are related as they re? Thus atm tensile and compressive forces are involved in adhesion tape testing.
