If you feel that your comments have not received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below. Dhave advised this subcommittee that the properties of these tapes were changed. If the metal has not 3539-02 reached make another grid in a different location.

Ashm supplier that has assisted in the re? Criteria deemed essential for a test to warrant large-scale acceptance are: What are the hazards of powder coatings? 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.

33590-2 the tape into place by finger in the area of the incisions and then rub firmly with the eraser on the end of a pencil. For multicoat systems where adhesion failure may occur between or within coats, the adhesion of the coating system to the substrate is not determined.


Summary of Test Methods 3. Smooth the tape into place by? Criticism of these tests arises when they are used to quantify the strength of adhesive bonding. Flaking and detachment worse than Grade 1.

Users of it should, therefore, check whether s material gives comparable results to previous supplied material.

More importantly, in this instance the test is being applied beyond r intended scope. Then dry or prepare the surface, or both, as agreed upon between the purchaser and the seller. For large structures make sufficient tests to ensure that the adhesion evaluation is representative of the whole surface.

They do not distinguish between asym levels of adhesion for which more sophisticated methods of measurement are required. Apparatus and Materials However, with the tape test, failures within the substrate or coating layers are rare because the tape adhesive is not usually strong enough to exceed the cohesive strengths of normal substrates and organic coatings.

Procedure for X-CUT TAPE TEST METHOD-ASTM D3359-02

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 3359-0, as when testing primers alone, or within or between coats in multicoat systems.

For tests in the? Thus both tensile and compressive forces are involved in adhesion tape testing. Some commercial tapes are manufactured to meet minimum standards.



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. The color under the tape is a useful indication of when good contact has been made. But this, in fact, is not their purpose. Also, Test Method B is not considered suitable for?

However, the precision values given in A number in parentheses indicates the year of last reapproval. By design it was made as simple as possible to perform, and requires a minimum of specialized equipment and materials that must meet certain speci? When making the incisions, use the straightedge and cut through the coating to the wstm in one steady motion.

D5 Creation Powered by: It is assumed that coating removal occurs when the tensile force generated along the latter interface, which is a function of the rheological properties of the backing and adhesive layer materials, is greater than the bond strength at the coating-substrate interface or cohesive strength of the coating. Cohesive failure within the coating? NOTE 5—If desired or speci?
