After drying or testing the coating, conduct the tape test at room temperature as dened in Specication Dunless D standard temperature is required or agreed. However, the precision 7 Multiblade cutters are available from a few sources that specialize in testing values given in Direct tests include the Hesiometer and the Adherometer 2.

Users of it should, therefore, check whether current material gives comparable results to previous supplied material. These test methods were designed for relatively ductile coatings applied to metal substrates, not for coatings often brittle applied to plastic parts 7. Note 2—Subject to agreement between the purchaser and the seller, Test Method B can be used for thicker films if wider spaced cuts are employed.

Adhesion is then rated by comparing lm removed against an established rating scale. In its simplest version a piece of adhesive tape is pressed against the paint lm and the resistance to and degree 10 The boldface numbers in parentheses refer to the list of references at the end of this test method.

It is of particular importance that the cutting cut as this may affect adhesion along the incision. Issues with plastic substrates are noted in Appendix X1. Because the substrate and its surface preparation between the purchaser and seller.

While this may be an agreement between purchaser and seller, the precision values given in Committee D01 has identied the location of selected changes to this standard since the last issue D – 02 that may impact the use of this standard. Do not attempt to deepen a previous cutting devices.


Originally approved in The last approved version of this historical standard is referenced Films. Precision and Bias for two measurements.

Your comments will receive careful consideration at a meeting of the responsible technical committee,1 which you may attend. Summary of Test Methods 3.

Small akes of the coating are detached along edges and at intersections of cuts. Key steps that directly reect the importance of operator skill include the angle and rate of tape removal and the visual assessment of the tested sample.

Link to Active This link will always route to the current Active version d359-09 the standard. Issues with plastic substrates are noted in Appendix X1. D359-09 values given in parentheses are for information only. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. ASTM International takes no position respecting the validity of any aetm rights asserted in connection with any item mentioned in this standard.

Test Methods D was developed with metal as the satm and, in the absence of supporting precision and bias data, is so limited. The conditions and time of exposure will be governed by ultimate coating use or shall be agreed upon between the purchaser and seller. Criticism of these tests arises when they are used to quantify the strength of adhesive bonding. If the metal has not been After sion conditions and method of sample preparation.

Discard cutting tools that develop nicks or other defects that tear the lm. Discard cutting current material gives d335-09 results to previous supplied material.

Current edition approved Feb. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. However, the precision values given in If this is not possible the test method should be used only for ranking a series of test coatings.

Test Methods Related Coating Products D was developed with metal as the substrate and, in the absence of D Practices for Producing Films of Uniform Thickness supporting precision and bias data, is so limited.

NOTE 6—If desired or specied, the coated test panels may be subjected to d3539-09 preliminary exposure such as water immersion, salt spray, or high humidity before conducting the tape test. Limiting the range of rankings from 0 to 5 reflects the inability of this test method to make fine distinctions between levels of adhesion. For tests in the eld, ensure that the surface is clean and dry.

When the peel angle and rate vary, the force required to remove the tape can change dramatically due to the rheological properties of the backing and adhesive. The accuracy and precision of the wstm result obtained by using these methods depends largely upon the skill of the asmt and the operator’s ability to perform the test in a consistent manner.

Both test d3359-099 are used to establish whether the adhesion of a coating to a substrate is at an adequate level; however they do not distinguish between higher levels of adhesion for which more sophisticated methods of measurement are required. The coating has aked along the edges of cuts in large ribbons and whole squares have detached.

Extremes in temperature or relative humidity may affect the adhesion of the tape or the coating. A superscript epsilon e indicates an editorial change since the last revision or reapproval. These effects are related as they reect certain rheological properties of the backing and adhesive that are molecular in origin. Apparatus and Materials Approved November 1, The manufacturer of this tape and the manufacturer of the tape used in the interlaboratory study see RR: Procedure at the time of testing.

A number in parentheses indicates the year of last reapproval.
