If testing coatings on non-metallic substrates, either Test Method A or Test Method B may be more appropriate and the method astm d3359 free should be discussed by interested parties.
ASTM D cross hatch tape test_百度文库
They do not distinguish between higher levels of adhesion for which astm d3359 free sophisticated methods of measurement are required. A similar test method, ISOpermits tests on non-metallic substrates for example, wood and plaster.
astm d3359 free Test Method D was developed with metal as the substrate and, in the absence of supporting precision and bias data, is so limited.
Limiting the range of rankings from 0 to 5 reflects the inability of this test method to make fine distinctions between levels of adhesion.
The intra- and inter-laboratory precision of this test method is similar to other test methods for coated substrates for example, Fre Method D and Test Method Dand is insensitive to all but large differences in adhesion. Astm d3359 free values given in parentheses are for information only. Referenced Astm d3359 free purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
The accuracy astm d3359 free precision of the test result obtained by using v3359 methods depends largely upon the skill of the operator and the operator’s ability to perform the test in a consistent manner. 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 different coatings to the same substrate, is of considerable usefulness in the industry.
It is astm d3359 free unexpected that different operators might obtain different results 12.
When the peel angle and rate vary, the force required to remove the tape can change dramatically astm d3359 free to the rheological properties of the backing and adhesive.
Historical Version s – view previous versions of standard. Precision and bias astm d3359 free on the d3359 is lacking.
Key steps that directly reflect the importance of operator skill astm d3359 free 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 atm on non-metallic substrates for example, wood and plasticalthough related precision and bias data is lacking.
Users shall not use intermediate values for ranking adhesion tests within this method.

Historical Version s – view 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 awtm astm d3359 free2.
Issues with aetm substrates are noted in Appendix X1. Link to Active This link will always astm d3359 free to the current Active version of the standard.
Astm d3359 free is the responsibility fre the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Variation in pull rate and peel angle can effect large differences in test values and must be minimized to assure reproducibility 3.
As such, no single tape is likely to be suitable for testing all coatings.
