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 technical committee,1 which you may attend.

Your comments are invited either for revision of this standard or for astj standards and should be addressed to ASTM International Headquarters. Cohesive failure within the coating? 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.

Although some rather brittle coatings may exhibit cohesive failure, the tape test adhesion method does not make provision for giving failure locality 7, 8. If this is not possible the test method should be used only for ranking a series of test coatings. Then dry or prepare the surface, or both, as agreed upon between the purchaser and the seller.

These test methods were designed for relatively ductile coatings applied to metal substrates, not atsm coatings often brittle applied to plastic parts 7. If the metal has not been reached make another grid in a different location. The color under the transparent tape is a useful indication of when good contact has been made. It is of 3395-02 importance that the cutting edge or edges be in good condition. There generally is difficulty, however, in 33599-02 these tests to basic adhesion phenomena.

In actuality, however, this force is distributed over a discrete distance O-A in Fig. After immersion, clean 3539-02 wipe the surface with an appropriate solvent which will not harm the integrity of the coating.

If the substrate has not been reached make another X in a different location. If the adhesion strength of the tape has not been determined, report the speci?

The values given in parentheses are for information only. Smooth the tape into place by? Do not attempt to deepen a previous cut as this may affect adhesion along the incision. When making successive single cuts with the aid of a guide, place the guide on the uncut area. Apparatus and Materials Discard cutting tools 33559-02 develop nicks or other defects that tear the film.

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 asym. A number 335902 parentheses indicates the year of last reapproval. Dhave advised this subcommittee that the properties of these tapes were changed. This standard has been approved for use by agencies of the Department of Defense.

Flaking and detachment worse than Grade 1. It is of particular importance that the cutting edges be in good condition. A astj epsilon e indicates an editorial change since the last revision or reapproval. Some commercial tapes are manufactured to meet minimum standards.

Key steps that directly re? Criteria deemed essential for a test to warrant large-scale acceptance are: NOTE 4—Coatings should be applied in accordance with Practice Dor as agreed upon between the purchaser and the seller.

Criticism of these tests arises when they are used to quantify the strength of adhesive bonding. Current edition approved Aug. Remove an additional length at a steady that is, not jerked rate and cut a piece about 75 mm 3 in. This standard is subject to revision at any time by the responsible technical committee and must be reviewed every?

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

For large structures make sufficient tests to ensure that the adhesion evaluation is representative of the whole surface. 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.

It should be noted, however, that multitip cutters10 provide good results only on test areas sufficiently plane that all cutting edges contact the substrate to the same degree. The color under the transparent tape is a useful indication of when good contact has been made.

When making the incisions, use the straightedge and cut through the coating to the substrate in one steady motion. 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.

For tests in the field, ensure that the surface is clean and dry. D — 02 results with the adhesion rating s.

For large structures make sufficient tests to ensure that the adhesion evaluation is representative of the whole surface.
