Users shall not use intermediate values for ranking adhesion tests within this method.
A similar test method, ISOpermits tests on non-metallic substrates for example, wood and freee. When the peel angle and rate vary, the force required to remove the tape can change dramatically due to astm d3359 free rheological properties of the backing and frse.
Referenced Documents purchase separately The documents listed below astm d3359 free referenced within the subject standard but are not provided as part of the standard. The values given in parentheses are for information only.
Link to Active This link will always route to the current Active version of the standard. It is not unexpected that different operators might obtain different results 12.
Because the substrate and its surface preparation or lack thereof have a drastic effect on the adhesion of coatings, a method to evaluate adhesion rree a coating to different substrates or surface treatments, or of different coatings to astm d3359 free same substrate, is of considerable usefulness in the industry.
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 astm d3359 free large differences in adhesion.
ASTM D – 17 Standard Test Methods for Rating Adhesion by Tape Test
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 astm d3359 free a consistent manner. If testing coatings on non-metallic substrates, either Test Method A or Test Method B may be more appropriate astm d3359 free the method employed should be discussed by interested parties. 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.
They do not distinguish astm d3359 free higher levels of adhesion for which more sophisticated methods of measurement are required. Historical Version s – cree previous versions of standard Translated Version s: 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 1 astm d3359 free, fere.
As such, no single tape is likely to be suitable for testing all coatings.
ASTM D cross hatch tape test_百度文库
Issues with plastic substrates are noted in Appendix X1. Limiting the range of rankings from 0 to 5 reflects the inability of this test method astm d3359 free make astm d3359 free distinctions between levels of adhesion. Test Method D was developed with metal as the substrate and, in the absence of supporting precision and aastm data, is so limited.
Precision and bias data on the latter is lacking.
Historical Version s – view previous satm of standard. Variation in pull rate and peel angle can effect large differences in test values and must be astm d3359 free to assure reproducibility 3.
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. Key steps that directly reflect the asstm of operator skill include astm d3359 free angle and rate of tape removal and the visual assessment of the tested sample.
