They do not distinguish between higher levels of adhesion for which more sophisticated methods of measurement are required. When the peel angle and rate vary, the force required to remove the tape can change dramatically 092 to the rheological properties of the backing and adhesive.

ASTM D – 17 Standard Test Methods for Rating 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. Precision and bias data on the later is lacking. It is not unexpected that different operators might obtain different results 12. A similar test method, ISOpermits tests on non-metallic substrates for example, wood and plaster.

Note 3—It should be recognized that differences in adherability of the coating surface can affect the results astn with coatings having the same inherent adhesion.

Limiting the range of rankings from 0 to 5 reflects the inability of this test method to make fine distinctions between levels of adhesion. Test Methods D was developed with metal as the substrate and, in the absence of supporting precision and bias data, is so limited.

ASTM D – 09e2 Standard Test Methods for Measuring Adhesion by Tape Test

Because the substrate and its surface preparation or lack thereof have a drastic effect on the adhesion of coatings, a method to evaluate adhesion of a coating to different substrates or surface treatments, or of different coatings to the same substrate, is of considerable usefulness in the industry. Precision and bias data on the latter is lacking. 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.

Variation in pull rate and peel angle can effect large differences in test values and must be minimized to assure reproducibility 3. The intra- and inter-laboratory precision of this test method is similar to other test methods for coated substrates for example, Test Method D and Test Method Dand is insensitive to all but large differences in adhesion.

Note 2—Subject to agreement between the purchaser and the seller, Test Method B can be used for thicker films if wider spaced cuts are employed. These test methods have been reported being used to measure adhesion of organic coatings on non-metallic substrates for example, wood 09e22 plasticalthough related precision and bias data is lacking. The accuracy and precision of the test result obtained by using these methods depends largely upon the skill of the operator and the asmt ability to perform the test in a consistent manner.

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.

— A similar test method, ISOpermits tests on soft substrates for example, wood and plaster. Note 1—This test method has been reported being used to measure adhesion of organic coatings on soft substrates for example, wood and plastic. Historical Version s – view previous versions of standard. If testing coatings on non-metallic substrates, either Test Method A or Test Method B may be more appropriate and the method employed should be discussed by interested parties.
