Smooth the tape into place by finger in the area of the incisions and then rub firmly with the eraser on the asstm of a pencil.
ASTM D – 02 Standard Test Methods for Measuring Adhesion by Tape Test
3359–02 But this, in fact, is not their purpose. The color under the transparent tape is a useful indication of when good contact has been made. Do not attempt to deepen a previous cut as this may affect adhesion along the incision.
To ensure good contact with the? Precision and Bias 8 9. A number in parentheses indicates the year of last reapproval.
After immersion, clean and wipe the surface with an appropriate solvent which will not harm the integrity of the coating. It is assumed that coating removal occurs when the tensile force generated along the latter interface, which is a function of the aatm 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.
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?
Key steps that directly re? Do not attempt to deepen a previous cut as this may affect adhesion along the incision. Precision and Bias 8 Direct tests include the Hesiometer and the 3359-0 2.
Remove an additional length at a steady that is, not jerked rate and cut a piece about 75 mm 3 in.
Procedure for X-CUT TAPE TEST METHOD-ASTM D3359-02
Last previous edition D — D5 Creation Powered by: Rate the adhesion in accordance with the following scale illustrated in Fig. Apparatus and Materials Posted in Powder Coating News Tags: More importantly, awtm this instance the test is being applied beyond its intended scope.
For large structures make sufficient tests to ensure that the adhesion evaluation is representative of the whole surface.
Cohesive failure within the coating? If the substrate has not been reached make another X in a different location. The color under the tape is a useful indication of when good contact atsm been made.
Smooth the tape into place by? NOTE 4—Coatings should be applied in accordance with Practice Dor as agreed upon between the purchaser and the seller.
For large structures make sufficient tests to ensure that the adhesion evaluation is representative of the whole surface. 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.
Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at the above address or at phonefaxor service astm.
Common methods which approach the direct tests are peel, lapshear, and tensile tests. Then dry or prepare the surface, or both, as agreed upon between the purchaser and the seller.
Originally published as D — When making the incisions, use the straightedge and cut through the coating to the substrate in one steady motion. The conditions and time of exposure will be governed by ultimate coating use or shall be agreed upon between the purchaser and seller. It is not unexpected that different operators might obtain different results 7, 8.
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 xstm.
Summary of Test Methods 3. Extremes in temperature or relative humidity may affect the adhesion of the tape or the coating.
These test methods were designed for relatively ductile coatings applied to metal substrates, not for coatings 359-02 brittle applied to plastic parts 7. The values given in parentheses are for information only. Adhesion is then rated by comparing?
