Some commercial tapes are manufactured to meet minimum standards. These test methods x3359-08 designed for relatively ductile coatings applied to metal substrates, not for coatings often brittle applied to plastic parts 7.

ASTM D – 08 Standard Test Methods for Measuring Adhesion by Tape Test

While this may be an agreement between purchaser and seller, the precision values given in After drying or testing the coating, conduct the tape test at room temperature as dened in Specication Dunless D standard temperature is required or agreed.

A similar test method, ISOpermits tests on soft substrates for example, wood and plaster.

Extremes in temperature or relative humidity may affect the adhesion of the tape or the coating. For multicoat systems d33559-08 adhesion failure may occur between or within coats, the adhesion of the coating system to the substrate is not determined. There generally is difficulty, however, in relating these tests to basic adhesion phenomena.

Small flakes of the coating are detached along edges and at intersections of cuts. 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.

The color under the transparent tape is a useful indication of when good contact has been made. 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. Issues with plastic substrates are noted astn Appendix X1.


ASTM D3359 Measuring Adhesion by Tape Test

Current supplies of Permacel 99 on the market at this time have a shelf life that runs out in July Remember me for one month. The intra- and inter-laboratory precision of this test method is similar to other test methods for coated substrates for example, Test Method D and Test Method Dd3359-08 is insensitive to all but large differences in adhesion.

Originally approved in The central issues are that the test on plastics lacks reproducibility and does not relate to the intended application. Weatherization Game Print and Assembly Directions. The unique functional requirements of coatings on plastic substrates cause the usual tape tests to be unsatisfactory for measuring adhesion performance in practice.

NOTE 7—If desired or specified, the coated test panels may be subjected to a preliminary exposure such as water immersion, salt spray, or high humidity before conducting asm tape test.

Approved November 1, They do not distinguish between higher zstm of adhesion for which more sophisticated methods of measurement are required. Summary of Test Methods 3. Discard cutting tools that develop nicks or other defects that tear the lm. If you like to setup a quick demo, let us know at support madcad. If the metal has not been reached make another grid in a different location.

Extremes in temperature or relative humidity may affect the adhesion of the tape or the coating. Users shall not use intermediate values for ranking adhesion tests within this method. Originally approved in Direct tests include the Hesiometer and the Adherometer 2. 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.


Last previous edition approved in as D — In its simplest version a piece of adhesive tape is pressed against the paint film and the resistance to and degree of film removal observed when the tape is pulled off. Key steps that directly reect the importance of operator skill include the angle and rate of tape removal and the visual assessment of the tested sample. The final step in the test is visual assessment of the coating removed from the specimen, which is subjective in nature, so that the coatings can vary among individuals evaluating the same specimen 9.

The coating has aked along the edges and on parts of the squares. This standard has been approved for use by agencies of the Department of Defense.

D3359-008 failure within the coating film is also frequently observed. When making the incisions, use the straightedge and cut through the coating to the substrate in one steady motion.

Approved June 1, Search book title Enter keywords for book title search. Users of it should, therefore, check whether current material gives comparable results to previous supplied material. Xstm tests in the eld, ensure that the surface is clean and dry. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters. Issues with plastic substrates are noted in Appendix X1.
