Smooth the tape into place 33599-02 finger in the area of the incisions and then rub firmly with the eraser on the end of a pencil. Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at the above address or at phonefaxor service astm.

It is of particular importance that the cutting edge or edges be in good condition. If the adhesion strength of the tape has not been determined, report the speci?

Last previous edition D — The intra- and inter-laboratory precision of this test method is similar to other widely-accepted tests for coated substrates for example, Test Sstm D and Test Method Dbut this is partly the result of it being insensitive to all but large differences in adhesion.

Adhesion is then rated by comparing? It is of particular importance that the cutting edges be in good condition.

If the metal has not been reached make another grid in a different location. Precision and Bias 9. They do not distinguish between higher levels of adhesion for which more sophisticated methods of measurement are required.

Apparatus and Materials 5. Variation in pull rate and peel angle can effect large differences in test values and must be minimized to assure reproducibility 9.

Apparatus and Materials This standard is subject to revision at any time by the responsible technical committee and must be reviewed every?

For tests in the? 33590-2, because tapes change on storage, bond strengths of the tape may change over time 7, 8. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

If this is not possible the test method should be used only for ranking a series of test coatings. When making the incisions, use the straightedge and cut through the coating to the substrate in one steady motion. These test aztm were designed for relatively ductile coatings applied to metal substrates, not for coatings often brittle applied to plastic parts 7.

One supplier that has assisted in the re? After immersion, clean and wipe the surface with an appropriate solvent which will not harm the integrity of adtm coating.

More importantly, in this instance the test is being applied beyond its intended scope. As Mittal 1 12 has pointed out, the answer is astn yes and no. In actuality, however, this force is distributed over a discrete distance O-A in Fig. When making successive single cuts with the aid of a guide, place the guide on the uncut 3359-0. These effects are related as they re? In its simplest version a piece of adhesive tape is pressed against the paint?

By design it was made as simple as possible to perform, and requires a minimum of specialized equipment and materials 3359-0 must meet certain speci? Dhave advised this subcommittee that the properties of these tapes were changed.

Further, the tape test does not give an absolute value for the force required for bond rupture, but serves only as astmm indicator that some minimum value for bond strength was met or exceeded 7, 8. Smooth the adtm into place by? Major limitations of the tape test are its low sensitivity, applicability only to coatings of relatively low bond strengths, and non-determination of adhesion to the substrate where failure occurs within a single coat, as when testing primers alone, c within or between coats in multicoat systems.

Current edition approved Aug. D — 02 results with the adhesion rating s. Remove an additional length at a steady that is, not jerked rate and cut a piece about 75 mm 3 in.

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. Although some rather brittle coatings may exhibit cohesive failure, the tape test adhesion method does not make provision for giving failure locality 7, 8.
