NOTE 5—If desired or speci? ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard.

It is of particular importance that the cutting edge or edges be in good condition. For tests in the field, ensure that the surface is clean and dry. What are the hazards of powder coatings?

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

Qstm importantly, in this instance the test is being applied beyond its intended scope. Differences in tapes used can lead to different results as small changes in backing stiffness and adhesive rheology cause large changes in the tension area. To ensure good contact with 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.

There generally is difficulty, however, in relating these tests to basic adhesion phenomena. Some commercial tapes are manufactured to meet minimum standards. A superscript epsilon e indicates an editorial change since the last revision or reapproval.

ASTM D – 02 Standard Test Methods for Measuring Adhesion by Tape Test

For multicoat systems where adhesion failure may asttm between or within coats, the adhesion of the coating system to the substrate is not determined. The color under the tape is a useful indication of when good contact has been made.

Also, Test Method B is not considered suitable for? Do not attempt to deepen a previous cut as this may affect adhesion along the incision. Criticism of these tests arises when they are used to quantify the strength of adhesive bonding. Precision and Bias 9. Also, because tapes change on storage, bond strengths of the tape may change over time 7, 8. The conditions and time of exposure will be governed by ultimate coating use or shall be agreed upon between the purchaser and seller. 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.

Key steps that directly re? In its simplest version a piece of adhesive tape is pressed against the paint? Smooth the tape into place by? The color 33559-02 the transparent tape is a useful indication of when good contact has been made. NOTE 4—Coatings should be applied in accordance with Practice Dor as agreed upon between the purchaser and the seller. 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.

After immersion, clean and wipe the surface with an appropriate solvent which will not harm the integrity of the coating. 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 c adhesion.

Apparatus and Materials Asfm limited scale of 0 to 5 was selected deliberately to avoid a false impression of being sensitive. Do not attempt to deepen a previous astmm as this may affect adhesion along the incision. 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 unique functional requirements of coatings on plastic substrates cause the usual tape tests to be unsatisfactory for measuring adhesion performance in practice.

Further, the tape test does not give an absolute value for the force 33599-02 for bond rupture, but serves only as an indicator that some minimum value for bond strength was met or exceeded 7, 8.


These effects are related as they re? Summary of Test Methods 3. This standard has been approved for use by agencies of the Department of Defense. If the adhesion strength of the tape has not been determined, report the specific tape used and its manufacturer.

Criteria deemed essential for a test to warrant large-scale acceptance are: If this is not possible the test method ast be used only for ranking a series of test coatings. It should be noted, however, asfm multitip cutters10 provide good results only on test areas sufficiently plane that all cutting edges contact the substrate to the same degree.

Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. Your comments will receive careful consideration at a meeting of the responsible 33359-02 committee,1 which you may attend.

Common methods which approach the direct tests are peel, lapshear, and tensile tests. As Mittal 1 12 has pointed out, the answer is both yes and no. Although some rather brittle coatings may exhibit cohesive failure, the tape test adhesion method does not make provision for giving failure locality 7, 8. Cohesive failure within the coating?

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. Your comments are invited either for revision of astn standard or for additional standards and should be addressed to ASTM International Headquarters.
