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.

Historical Version s – view previous versions of standard. Because the astm d3359 free 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.

Historical Version s – view previous versions of standard Translated Version s: The accuracy and precision of the test result obtained by using these methods depends largely upon the skill of the operator and the operator’s ability to perform the test in a consistent manner. It is not unexpected that different operators might obtain different results astm d3359 free2.

They do not distinguish between higher levels of adhesion for astm d3359 free more sophisticated methods of measurement are required. 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. The values given in parentheses are for information only.

Users shall not use intermediate values for ranking adhesion tests within this method. When the peel angle and rate vary, the force required to remove the tape can change frre due to the rheological properties of the backing and adhesive.

Precision and bias data on the latter is lacking. Limiting the range of rankings from 0 to 5 reflects the inability of this test method to make fine distinctions astm d3359 free levels of astm d3359 free.

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. Variation in pull astm d3359 free and peel angle can effect large differences in test values and must be minimized to assure reproducibility 3.

Test Method D was developed with metal as astm d3359 free substrate and, in the absence of supporting precision and bias data, is so limited. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided astm d3359 free part of the standard.

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. 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.

A similar test method, ISOpermits tests on non-metallic substrates for example, wood and plaster. As such, no single tape is likely to be suitable for testing all coatings. Issues with plastic substrates are noted in Appendix X1.

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 Astm d3359 free Dand is insensitive to all but large differences in adhesion.
