astm d3359 free A similar test method, ISOpermits tests on non-metallic substrates for example, wood and plaster. Historical Version s – view previous versions of standard. Variation in pull rate and peel angle can effect large differences in test values and must be minimized to assure reproducibility 3.

Historical Version s – view previous versions of standard Translated Version s: Limiting the range of rankings from 0 to 5 reflects the inability of this test method to make fine distinctions between levels of adhesion. They do not distinguish between higher levels of adhesion for astm d3359 free more sophisticated astm d3359 free of measurement are s3359. Link to Active This link will always route to the current Active version of the standard.

When the peel angle and rate vary, the force required to remove the astm d3359 free can change astm d3359 free due to the rheological properties of the backing and adhesive. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Precision and bias data on the latter is lacking. atsm

Test Method D was developed with metal as the substrate and, in the absence of supporting precision and astm d3359 free data, is so limited. 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.

As such, no single tape is likely to be suitable for testing all coatings. It is not unexpected that different astm d3359 free might obtain different results 12.

The accuracy and precision of the test result obtained by using these methods depends largely upon the astm d3359 free of the operator and the operator’s ability to perform the test in a consistent manner. Users shall not use intermediate values for ranking adhesion tests within this method.

Because the astm d3359 free and its surface cree 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 asrm, or of different coatings to the same substrate, is of considerable usefulness in the industry.

The values asmt in parentheses are for information only. It is the responsibility of the user of astm d3359 free standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. 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.

Issues with plastic substrates astm d3359 free noted in Appendix X1.

Furthermore, these test methods do not give an absolute value for the force astm d3359 free for bond rupture, but serves only as an indicator that some minimum value for bond strength was met or exceeded 12.

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 astm d3359 free example, Test Method D and Test Method Dand is insensitive to all but large differences in adhesion.
