Criteria deemed essential for a astn to warrant large-scale acceptance are: Originally approved in Note 1This test method has been reported being used to measure adhesion of organic coatings on soft substrates for example, wood and plastic.

Apparatus and Materials As Mittal 1 9 has pointed out, the answer is both yes and no.

Search book title Enter keywords for book title search. Both test methods 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.

For example, when the peel removal force of the tape from the coating used earlier by Task Group D Summary of Test Methods 3. Key steps that directly reflect the importance of operator skill include the angle and rate of tape removal and the visual assessment of the tested sample.

Users of it should, therefore, check whether current material gives comparable results to previous supplied material. If this is not possible the test method should be used only for asrm a series of test coatings.

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

Also, because tapes change on storage, bond strengths of the tape may change over time 7, 8. When making successive single cuts with the aid of a guide, place the guide on the uncut area. The color under the transparent tape is a useful indication of when good contact has been made. For tests in the field, ensure that the surface is clean and dry.

Although some rather brittle coatings may exhibit cohesive failure, the tape test adhesion method does not make provision for giving failure locality 7, 8. Check for atness with a straight edge such as that of the tempered steel rule A similar test method, ISOpermits tests on non-metallic substrates for example, wood and plaster.

Some commercial tapes are manufactured to meet minimum standards.

Also, Test Method B is not considered suitable for films thicker than 5 mils ? Adhesion is then rated by comparing film removed s3359-08 an established rating scale. They do not distinguish between higher levels of adhesion for which more sophisticated methods of measurement are required.

Last previous edition approved in as D — NOTE 6—If desired or specied, the coated test panels may be subjected to a preliminary exposure such as water immersion, salt asgm, or high humidity before conducting the tape test.

It is of particular importance that the cutting edges be in good condition. But it can also be said that it is ast to obtain an indication of relative adhesion performance. Precision and bias data on the latter is lacking.

Issues d33590-8 plastic substrates are noted in Appendix X1. A similar test method, ISOpermits tests on soft substrates for example, wood and plaster. Permission rights to photocopy the standard may also be secured from the ASTM website www.

A similar test method, ISOpermits tests on soft substrates for example, wood and plaster. Justification for the cutting step is reasonable as cutting provides a free edge from which peeling can begin without having to overcome the cohesive strength of the coating layer.

Also, because tapes change on storage, bond strengths of the tape may change over time 7, 8. NOTE 7—If desired or specified, the coated test panels may be subjected to a preliminary exposure such as water immersion, salt spray, or high humidity before conducting the tape test. Since an intact lm aatm appreciable adhesion is frequently not removed at all, the severity of the test is usually enhanced by cutting into the lm a gure X or a cross hatched pattern, before applying and removing the tape.

The color under the tape is a useful indication of when good contact has been made.

ASTM D Measuring Adhesion by Tape Test

A significant compressive force arises from the response of the tape backing material to being stretched. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. They do not distinguish between higher levels of adhesion for which more sophisticated methods of measurement are required. There were no books found for the applied search filters. Extremes in temperature or relative humidity may affect the adhesion of the tape or the coating.

The color under the transparent tape is a useful indication of when good contact has been made. The central issues are that the test on plastics lacks reproducibility and does not relate to the intended application. They do not distinguish between higher levels of adhesion for which more sophisticated methods of measurement are required.

Extremes in temperature or relative humidity may affect the adhesion of the tape or the coating. Today, some 12, ASTM standards are used around the world to improve product quality, enhance safety, facilitate d3359-8 access and trade, and build consumer confidence. If the peel angle and rate vary, the force required to remove the tape can change dramatically. These tests do not strictly meet d3359-008 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.

Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters.

Users shall not use intermediate values for ranking adhesion tests within this method. The unique functional requirements of coatings on plastic substrates cause the usual tape tests to be unsatisfactory for measuring adhesion performance in practice.

Issues with plastic substrates are noted in Appendix X1. Rate the adhesion axtm accordance with the following scale illustrated in Fig.
