The conditions and time of exposure will be governed by ultimate coating use or shall be agreed upon between the purchaser and seller.
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 treatments, or of different coatings to the same substrate and treatment, is of considerable usefulness in the industry.
But this, in fact, is not their purpose.
Current edition approved Feb. The intra- and inter-laboratory precision of this test method is similar to other widely-accepted tests for coated substrates for example, Test Method D d3359–08 Test Method Dbut this is partly the result of it being insensitive to all but large differences in adhesion.
Several factors that contribute to these differences include asmt composition and topology: Thus both tensile and compressive forces are involved in adhesion tape testing. 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.
S3359-08 2Subject to agreement between the purchaser and the seller, Test Method B can be used for thicker films if wider spaced cuts are employed.

There were no books found for the applied search filters. Weatherization Game Print and Assembly Directions. Committee D01 has identified the location of selected changes to this standard since the last issue D – 07 that may impact the use of this standard.
ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard. However, with the tape test, failures within the substrate or coating layers are rare because the tape adhesive is not usually strong enough to exceed the cohesive strengths of normal substrates and organic coatings.
As Mittal 1 9 has pointed out, the answer is both yes and no. Then dry or prepare the surface, or both, as agreed upon between the purchaser and the seller. Also, Test Method B is not considered suitable for lms thicker than 5 mils m. Limiting the range of rankings from 0 to 5 reflects the inability of this test method to make fine distinctions between levels of adhesion.
It is of particular importance that the cutting edge or aastm be in good condition.
ASTM D Measuring Adhesion by Tape Test
As such, no single tape is likely to be suitable for testing all coatings. Approved November 1, The values given in parentheses are for information only.
The color under the tape is a useful indication of when good contact has been made. If more information is asstm about the tapes being c3359-08 in the D Do not attempt to deepen a previous cut as this may affect adhesion along the incision.
Apparatus and Materials 5. Both concerns are well founded: Several factors that contribute to these differences include coating composition and topology: The unique functional requirements of coatings on plastic substrates cause the usual tape tests to be dd3359-08 for measuring adhesion performance in practice.
Historical Version s – view previous versions of standard Translated Version s: The coating has flaked along the edges and on parts of the squares.
ASTM D 3359 – 09 Standard Test Methods for Measuring Adhesion by Tape Test
Test Methods D was developed with metal as the substrate asym, in the absense of supporting precision and bias data, is so limited. Last previous edition approved in as D — Current supplies of Permacel 99 on the market at this time have a shelf life that runs out in July They do not distinguish between higher levels of adhesion for which more sophisticated methods of measurement are required. Discard cutting tools that develop s3359-08 or other defects that tear the lm.
Variation in pull rate and peel angle can effect large differences in test values and must be minimized to assure reproducibility 3.
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. Precision and bias data on the later d33599-08 lacking.
