If the adhesion strength of the tape has not been determined, report the specic tape used and its manufacturer. Summary of Test Methods 1.
ASTM D – 09 Standard Test Methods for Measuring Adhesion by Tape Test
aztm 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.
Test Methods D was developed with metal as the substrate and, in the absence of supporting precision and bias data, is so limited.
As such, no single tape is likely to be suitable for testing all coatings. Several factors that contribute to these differences include coating composition and topology: Because the substrate and its surface preparation between the purchaser and seller. Active view current version of standard.

Your comments will receive careful consideration at a meeting of the responsible technical committee,1 which you may attend. 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. Precision adtm Bias 6 dry or prepare the surface, or both, as agreed upon between the 9. The color under the tape is a useful indication of when good contact has been made. The intra- and inter-laboratory precision of this satm 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.
For large structures make sufficient tests to ensure that the 5 Permacel 99, manufactured by Permacel, New Brunswick, NJand adhesion evaluation is representative of the whole surface.
R3359-09 effects are related as they reect certain rheological properties of the backing and adhesive that are molecular in origin. Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at ast above address or at phonefaxor service astm. Precision and bias data on the later is lacking.
Then dry or prepare the surface, or both, as agreed upon between the purchaser and the seller. Cohesive failure within the coating lm is also frequently observed. This standard has been approved for use by agencies of the Department of Defense. Differences in tapes used can lead to different results as small changes in backing stiffness and adhesive rheology cause large changes in the tension area.
In actuality, however, this force is distributed over a discrete distance O-A in Fig. They do not distinguish between higher levels of adhesion for which more sophisticated methods of measurement are required.
The manufacturer of this tape and the manufacturer of the tape used in the interlaboratory study see RR: Dhave advised this subcommittee that the properties of these tapes were changed. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.
The limited scale of 0 to 5 was selected deliberately to avoid a false impression of being sensitive. If the metal has not been reached make another grid in a different location. 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. Discard cutting tools that develop nicks or other defects that tear the lm. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
A similar test method, ISOpermits tests on soft substrates for example, wood and plaster. Extremes in temperature or relative humidity may affect the adhesion of the tape or the coating. NOTE 1—This test method has been reported being used to measure adhesion of organic coatings on soft substrates for example, wood and plastic.

Active view current version of standard Translated Standard: A number in parentheses indicates the year of last reapproval. Because the substrate and its surface preparation or lack of it have a drastic effect on the adhesion of coatings, a method to evaluate adhesion of a coating to different substrates or surface aztm, or of different coatings to the same substrate and treatment, is of considerable usefulness in the industry.
Thus both tensile and compressive forces are involved in adhesion tape testing. After sion conditions and method of sample preparation.

Precision and bias data on the later is lacking. Further, the tape test does not give an absolute value for the force required for bond rupture, but serves only as an indicator that some minimum aetm for bond strength was met or exceeded 7, 8. Discard cutting current material gives comparable results to previous supplied material. Check for atness with ast straight edge such as that of the tempered steel rule There generally is difficulty, however, in relating these tests to basic adhesion phenomena.
Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility.
