If this is not possible the test method should be used only for ranking a series of test coatings.

ASTM-D, –

Extremes in temperature or relative humidity may affect the adhesion of the tape or the coating. A similar test method, ISOpermits tests on soft substrates for example, wood and plaster.

Criticism of these tests arises when they are used to quantify the strength of adhesive bonding. Some commercial tapes are manufactured to meet minimum standards.

The coating has flaked along the edges of cuts in large ribbons and whole squares have detached. Precision and bias data on the later is lacking.

Flaking and detachment worse than Grade 1.

Precision and Bias5 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. Please login to your satm staff account to use this feature.

It is of particular importance that the cutting edges be in good condition. 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 value for bond strength was met or exceeded 7, 8. Several factors that contribute to these differences include coating composition and topology: Issues with plastic substrates are noted in Appendix X1.

However, the precision values given in Approved February 1, Land Use and Development. Today, some 12, ASTM standards are used around the world to improve product quality, enhance safety, facilitate market access and trade, and build consumer confidence. Criteria deemed essential for a test to warrant large-scale acceptance are: For example, when the peel removal force of the tape from the coating used earlier by Task Group D Direct tests include the Hesiometer and the Adherometer 2.

ASTM D – 08 Standard Test Methods for Measuring Adhesion by Tape Test

Rate the adhesion in accordance with the following scale illustrated in Fig. Smooth the tape into place by nger in the area of the incisions and then rub rmly with the eraser on the end of a pencil. If this is not possible the test method should be used only for ranking a series of test coatings.

These tests do not strictly meet all the criteria listed, but an appealing aspect of these tests is that 9 The boldface numbers in parentheses refer to the list of references at the end of this test method.

NOTE 2—Subject to agreement between the purchaser and the seller, Test Method B can be used for thicker lms if wider spaced cuts are employed. After immersion, clean and wipe the surface with an appropriate solvent which will not harm the integrity of the coating.

Precision and bias data on the later is lacking.

ASTM D 3359 – 09 Standard Test Methods for Measuring Adhesion by Tape Test

D — 08 Standard Test Methods for Measuring Adhesion by Tape Test1 This standard is issued under the xed designation D ; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision.

To ensure good contact with the film rub the tape firmly with the eraser on the end of a pencil. 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.

For multicoat systems where adhesion failure may occur between or within coats, the adhesion of the coating system to the substrate is not determined. Last previous edition approved in as D — After drying or testing the coating, conduct the tape test at room temperature as defined in Specification D, unless D standard temperature is required or agreed.

If the adhesion strength of the tape has not been determined, report the specific tape used and its manufacturer. 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. Note 1This test method has been reported being used to measure adhesion of organic coatings on soft substrates for example, wood and plastic.

Also, because tapes change on storage, bond strengths of the tape may change over time 7, 8. 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. 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 and Test Method Dbut this is partly the result of it being insensitive to all but large differences in adhesion.

The following editions for this book are also available Do not attempt to deepen a previous cut as this may affect adhesion along the incision. Flaking and detachment worse than Grade 1. No further reproductions authorized. Active view current version of standard. Extremes in temperature or relative humidity may affect the adhesion of the tape or the coating. Variation in pull rate and peel angle can effect large differences in test values and must be minimized to assure reproducibility 3.

Note 3—It should be recognized that differences in adherability of the coating surface can affect the results obtained with coatings having the same inherent adhesion.
