As such, no single tape is likely to be suitable astm d3359 free testing all coatings. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability astm d3359 free regulatory limitations prior to use. 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.
Furthermore, these test methods do not give an absolute value for the force required for bond rupture, but serves only as an indicator that astm d3359 free minimum value for bond strength was met or exceeded 12.
Variation in pull frree and peel angle can effect large differences in test values and must astm d3359 free minimized rree assure reproducibility 3.
Users shall not use intermediate values for ranking adhesion tests within this method. Because the substrate and its surface preparation or lack thereof have a drastic effect on the adhesion of astm d3359 free, 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.
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.
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.
When the peel angle and rate vary, the force required to remove the tape can change dramatically due to the rheological d3395 of the backing and adhesive. Referenced V3359 purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
Historical Version s – view previous versions of astm d3359 free Translated Version s: A similar test method, ISOpermits tests on non-metallic substrates for example, wood and plaster. The intra- and astm d3359 free ffee 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.
The values given in zstm are for information only. Issues with plastic substrates are noted in Appendix X1. Link to Active This link will always route to the current Astm d3359 free version of the standard.
Key steps that astm d3359 free reflect the importance of operator skill include the angle and rate of d33359 removal and the visual assessment of the tested sample. It is not unexpected that different operators might obtain different results 12.
ASTM D – 17 Standard Test Methods for Rating Adhesion by Tape Test
They do not distinguish between higher levels of adhesion for which more sophisticated methods of measurement are required. Test Method D was developed with metal as the substrate and, in astm d3359 free absence of supporting precision and bias data, is so limited.
Precision and bias data on the latter is lacking. Limiting the range of rankings from astm d3359 free to 5 reflects the inability of this test method to make fine distinctions between levels of adhesion. Historical Version s – view previous versions of standard.
