Although some rather brittle coatings may exhibit cohesive failure, the tape test adhesion method does not make provision for giving failure locality 7, 8. Apparatus and Materials 5.
ASTM D – 08 Standard Test Methods for Measuring Adhesion by Tape Test
Cohesive failure within the coating film is also frequently observed. These test methods have been reported being used to measure adhesion of organic coatings on non-metallic substrates for example, wood and plasticalthough related precision and bias data is lacking.
Summary of Test Methods 3.
Precision and bias data on the later is lacking. Originally approved in Users shall not use intermediate values for ranking adhesion tests within this method. Note 1This test method has been reported being used to measure adhesion of organic coatings on soft substrates for example, wood and plastic.
Precision and bias data on the later is lacking.
Your comments will receive careful consideration at a meeting of the responsible technical committee,1 which you may attend. A number in parentheses indicates the year of last reapproval.
Adhesion is then rated by comparing film removed against an established rating scale. Test Method D was developed with metal as the substrate and, in the absence of supporting precision and bias data, is so limited.
It is not unexpected that different operators might obtain different results 7, 8.
ASTM D – 17 Standard Test Methods for Rating Adhesion by Tape Test
The final step in the test is awtm assessment of the coating removed from the specimen, which is subjective in nature, so that the coatings can vary among individuals evaluating the same specimen 9.
A similar test method, ISOpermits tests on soft substrates for example, wood and plaster.
These test methods were designed for relatively ductile coatings applied to metal substrates, not for coatings often brittle applied to plastic parts 7. If this is not possible the test method should be used only for ranking a series of test coatings.
ASTM D3359 Measuring Adhesion by Tape Test
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Cut through the lm to the substrate in one steady motion using just sufficient pressure on the cutting tool to have the cutting edge reach the substrate.
Adhesion is then rated by comparing lm removed against an established rating scale. Direct tests include the Hesiometer and the Adherometer 2. ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard.
Users of alternative tapes should check whether the alternative tapes give comparable results to the Permacel P99 tape.
No items in cart. Some commercial tapes are manufactured to meet minimum standards. There generally is difficulty, however, in relating these tests to basic adhesion phenomena. Thus both tensile and compressive forces are involved in adhesion tape testing. While this may be an agreement between purchaser and d3359-80, the precision values given in If this is not possible the test method should be used only for ranking a series of test coatings. Both concerns are well founded: NOTE 6—If desired or specied, the coated test panels may be subjected to a preliminary exposure such as water immersion, salt spray, or high humidity before conducting the tape test.
There generally is difficulty, however, in relating these tests to basic adhesion phenomena.

For tests in the eld, ensure that the surface is clean and dry. 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. Thus both tensile and compressive forces are involved in adhesion qstm testing.
