Dree steps that directly reflect the importance of operator skill astm d3359 free the angle and rate of tape removal and astm d3359 free visual assessment of the tested sample. 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.

A similar test method, ISOpermits tests on non-metallic substrates for example, wood and plaster. Users shall not use intermediate values for ranking adhesion tests within this method.

Test Method D was developed with metal as the substrate and, in the absence of supporting precision and bias data, is so limited. Issues with plastic substrates are noted astm d3359 free Appendix X1. 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 astm d3359 free coatings to the same substrate, is of considerable usefulness in the industry.

Precision and bias data on the latter is lacking. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

The accuracy and precision of the test result obtained by using these astm d3359 free depends largely upon the skill of the operator and the operator’s ability to perform the test in a consistent manner.

They do not distinguish between qstm levels of adhesion for which more sophisticated methods of measurement are required. It is not unexpected that different operators might obtain different results 1astm d3359 free. When the peel angle and rate vary, the force required to remove the tape can change dramatically due to the rheological properties of astm d3359 free backing and adhesive.

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.

ASTM D – 17 Standard Test Methods for Rating Adhesion by Tape Test

The values given in parentheses are for information only. 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. 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.

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