ASTM D – 17 Standard Test Methods for Rating Adhesion by Tape Test
Are you sure you want to empty the cart? As such, no single tape is likely astk be suitable for testing all coatings.
The intra- and inter-laboratory precision of this test method is similar to other widely-accepted tests for coated substrates for example, Test Method D and Test Method Dbut this is partly the result of it being insensitive to all but large differences in adhesion. Both test methods are used to establish whether the adhesion of a coating to a substrate is at an adequate level; however they do not distinguish between higher levels of adhesion for which more asttm methods of measurement are required.

Users of it should, therefore, check whether current material gives comparable results to previous supplied material. However, the precision values given in Common methods which approach the direct tests are peel, lapshear, and tensile tests.
Remove an additional length at a steady that is, not jerked rate and cut a piece about 75 mm 3 in.
Furthermore, these test methods do 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 met or exceeded 12. If the metal has not been reached make another grid in a different location. Test Methods D was developed with metal as the substrate and, in the absense of supporting precision and bias data, is so limited. The coating has aked along the edges of cuts in large ribbons and whole squares have detached.

ASTM D3359 Measuring Adhesion by Tape Test
Key steps that directly reflect the importance of operator skill include the angle and rate of tape removal and the visual assessment of the tested sample. But it can also be said that it is possible to obtain an indication of relative adhesion performance.
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 adhesion. Current edition approved June 1, For multicoat systems where adhesion failure may occur between or within coats, the adhesion of the aastm system to the substrate is not determined. A number in parentheses indicates the year of last reapproval. If the adhesion strength of the tape has not been determined, report the specific tape used and its manufacturer.

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 met or exceeded 7, 8. It is of particular importance that the cutting edge or edges be in good condition.
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. The manufacturer of this tape and the manufacturer of the tape used in the interlaboratory study see RR: Today, some 12, ASTM standards are used around the world to improve product quality, enhance safety, facilitate market access and trade, and build consumer confidence.
The nal step in the test is visual 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. 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. Common methods which approach the direct tests are peel, lapshear, and tensile tests.
Rate the adhesion in accordance with the following scale illustrated in Fig. Summary of Test Methods 3. Criteria deemed essential for a test to warrant large-scale acceptance are:
