Last previous edition D — When making successive single cuts with aztm aid of a guide, place the guide on the uncut area. Direct tests include the Hesiometer and the Adherometer 2.
NOTE 5—If desired or speci? Users of it should, therefore, check whether current material gives comparable results to previous supplied material.
Because the substrate x 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, 3539-02 of different coatings to the 2 3 1. A superscript epsilon e indicates an editorial change since the last revision or reapproval.
Procedure for X-CUT TAPE TEST METHOD-ASTM D3359-02
However, the precision values given in For coatings on soft substrates, issues include how deep should this cut penetrate, and is it possible to cut only to the interface? Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. Standard Test Method f The color under the tape is a useful indication of when good contact has been made. The values given in parentheses are for information only.
NOTE 2—It should be recognized that differences in adherability of the coating surface can affect the results obtained with coatings having the same inherent adhesion. Smooth the tape into place by finger in the area of 3359–02 incisions and then rub firmly with the eraser on the end of a pencil. Common 33590-2 which approach the direct tests are peel, lapshear, and tensile tests. After immersion, clean and wipe the surface with an appropriate solvent which will not harm the integrity of the coating.
For tests in the? Discard cutting tools that develop nicks or other defects that tear the film. In actuality, however, this force is distributed over a discrete distance O-A in Fig. In its simplest version a piece of adhesive tape is pressed against the paint?
ASTM D – 02 Standard Test Methods for Measuring Adhesion by Tape Test
Discard cutting tools that develop nicks or other defects that tear the? Further, the tape test does not give an absolute value for the force required for bond rupture, but serves only as an indicator that some minimum value for bond strength was 3359-002 or exceeded 7, 8. They do not distinguish between higher levels of adhesion for which more sophisticated methods of measurement are required.
ASTM International takes no position respecting the validity of any patent rights asserted in connection with 3359-20 item mentioned in this standard. 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.
For tests in the field, ensure that the surface is clean and dry.
Criteria deemed essential for asm test to warrant large-scale acceptance are: But this, in fact, is not their purpose.
Some commercial tapes are manufactured to meet minimum standards. Precision and Bias 8 9.
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.
Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters.
If the adhesion strength of the tape has not been determined, report the speci? This standard is subject to revision at any time by the responsible technical committee and must be reviewed every?
There generally is difficulty, however, in relating these tests to basic adhesion phenomena.
Your comments will receive careful consideration at a meeting of the responsible technical committee,1 which you may attend. Extremes in temperature or relative humidity may affect the adhesion of the tape or the coating. For multicoat systems where adhesion failure may occur between or within coats, the adhesion of the coating system 3359-20 the zstm is not determined. Then dry or prepare the surface, or both, as agreed upon between the purchaser and the seller.
