Precision and Bias5 9. When making the incisions, use the straightedge and cut through the coating to the substrate in one d3359-80 motion. Direct tests include the Hesiometer and the Adherometer 2.
ASTM D 3359 – 09 Standard Test Methods for Measuring Adhesion by Tape Test
A similar test method, ISOpermits tests on soft substrates for example, wood and plaster. Nails, Spikes, and Staples. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. Rate the adhesion in v3359-08 with the following scale illustrated in Fig.
Approved February 1, For tests in the field, ensure that the surface is clean and dry. To ensure good contact with the lm rub the tape rmly with the eraser on the end of a aatm. Precision and bias data on the later is lacking. NOTE 6—Coatings should be applied in accordance with Practice D, or as agreed upon between the purchaser and the seller. Since an intact film with appreciable adhesion is frequently not removed at all, e3359-08 severity of the test is usually enhanced by cutting into the film a figure X or a cross hatched pattern, before applying and removing the tape.
d3359-8 After immersion, clean and wipe the surface with an appropriate solvent which will not harm the integrity of the coating. Discard cutting tools that develop nicks or other defects that tear the lm.
Also, because tapes change on storage, bond strengths of the tape may change over time 7, 8.
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. There were no books found for the applied search filters.

ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard. A number in parentheses indicates the year of last reapproval. D359-08 and Use 4. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters.
ASTM D3359 Measuring Adhesion by Tape Test
The manufacturer of this tape and the manufacturer of the tape used in the interlaboratory study see RR: Criticism of these tests arises when they are used to quantify the strength of adhesive bonding. 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 Dand is insensitive to all but large differences in adhesion.
If the peel angle and rate vary, the force required to remove the tape can change dramatically. Note 3—It should be recognized that differences in adherability of the coating surface can affect the results obtained with coatings having the same inherent adhesion. Thus both tensile and compressive forces are involved in adhesion tape testing.
Summary of Test Methods 3. 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. If you like to setup a quick demo, let us know at support madcad. They do not distinguish between higher levels of adhesion for which more sophisticated methods of measurement are required.
Some commercial tapes are manufactured to meet minimum standards. But it can also be said that it is possible to obtain an indication of relative adhesion performance. 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.
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, or within or between coats in multicoat systems. Although some rather brittle coatings may exhibit cohesive failure, the tape test adhesion method does not make provision for giving failure locality 7, 8.
Last previous edition approved in as D — No items in cart. Apparatus and Materials Active view current version of standard Translated Standard: Your comments will receive careful consideration at a meeting of the responsible technical committee,1 which you may attend.
This standard is subject to revision at any time by the responsible technical committee and must be reviewed every ve years and if not revised, either reapproved or withdrawn. Issues with plastic substrates are noted in Appendix X1. NOTE 4—Permacel P99 tape, aztm identified as suitable for this purpose, was withdrawn from manufacture in D3539-08 Contract Law in Higher Education. To ensure good contact with the film rub the tape firmly with the d3539-08 on the end of a pencil.
Check for atness with a straight edge such as that of the tempered steel rule Because the substrate and its surface preparation or lack of it have a drastic effect on the adhesion of coatings, a method to evaluate adhesion of a coating to different substrates or surface treatments, or of different coatings to the same substrate and treatment, is of considerable usefulness in the industry.
But this, in fact, is not their purpose. NOTE 2—Subject to agreement between the purchaser and the seller, Test Method B can be used for thicker films if wider spaced cuts are employed.
