A nu

2、mber in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1 NOTEFootnote 5 and 5.2 were corrected editorially in June 2010.2 NOTEFootnote 5 and 5.2 were corrected editorially and moved into Note 4 in 5.3 in

3、July 2010.This standard has been approved for use by agencies of the U.S. Department of Defense.1. Scope*1.1 These test methods cover procedures for assessing the adhesion of relatively ductile coating films to metallic substrates byapplying and removing pressure-sensitive tape over cuts made in the

4、 film.NOTE 1This test method has been reported being used to measure adhesion of organic coatings on soft substrates (for example, wood and plastic).Issues with plastic substrates are noted in Appendix X1.Asimilar test method, ISO 2409, permits tests on soft substrates (for example, wood and plaster

5、).Precision and bias data on the later is lacking. Test Methods D3359 was developed with metal as the substrate and, in the absence of supporting precisionand bias data, is so limited.1.2 Test Method A is primarily intended for use at job sitesin the field while Test Method B is more suitable for us

6、e in thelaboratory. laboratory or shop environments. Also, Test Method B is not considered suitable for films thicker than 5 mils(125m).125m (5 mils)NOTE 2Subject to agreement between the purchaser and the seller, Test Method B can be used for thicker films if wider spaced cuts areemployed.unless wi

7、der spaced cuts are employed and there is an explicit agreement between the purchaser and seller.1.3 These test methods are used to establishevaluate whether the adhesion of a coating to a substrate is at a generally adequatelevel.adequate for the users application. They do not distinguish between h

8、igher levels of adhesion for which more sophisticatedmethods of measurement are required.NOTE 3It should be recognized that differences in adherability of the coating surface can affect the results obtained with coatings having the sameinherent adhesion.1.4 This test method is similar in content (bu

9、t not technically equivalent) to ISO 2409.1.5 In multicoat systems adhesion failure may occur between coats so that the adhesion of the coating system to the substrateis not determined.1.6 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for infor

10、mation only.1.7 This standard does not purport to address the safety concerns, if any, associated with its use. It is the responsibility of theuser of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitationsprior to use.2. Reference

Significance and Use5.1 If In order for a coating is to fulfill its function of protecting or decorating a substrate, it must adhere to it for the expectedservi

28、ce life. the coating must remain adhered to the substrate. Because the substrate and its surface preparation (or lack of it)thereof) have a drastic effect on the adhesion of coatings, a method to evaluate adhesion of a coating to different substrates orsurface treatments, or of different coatings to

29、 the same substrate and treatment, substrate, is of considerable usefulness in theindustry.3 The last approved version of this historical standard is referenced on www.astm.org.4 Available from American National Standards Institute (ANSI), 25 W. 43rd St., 4th Floor, New York, NY 10036, http:/www.ans

31、ls of adhesion (see 1.3) should be recognized before using it. ). The intra- and inter-laboratory precision ofthis test method is similar to other widely-accepted teststest methods for coated substrates (for example, Test Method D2370 andTest Method D4060), but this is partly the result of it being

32、and is insensitive to all but large differences in adhesion. The limitedscale of Limiting the range of rankings from 0 to 5 was selected deliberately to avoid a false impression of being sensitive.reflectsthe inability of this test method to make fine distinctions between levels of adhesion. Users s

33、hall not use intermediate values forranking adhesion tests within this method.5.3 Extremes in temperatures or relative humidity may affect the adhesion of the tape or the coating.5.4 A given tape may not adhere equally well to different coatings due to several factors, including differences in coati

34、ngcomposition and topology. As such, no single tape is likely to be suitable for testing all coatings. Furthermore, these test methodsdo not give an absolute value for the force required for bond rupture, but serves only as an indicator that some minimum valuefor bond strength was met or exceeded (1

35、, 2).65.5 Operators performing these test methods must be trained and practiced in order to obtain consistent results. The accuracyand precision of the test result obtained by using these methods depends largely upon the skill of the operator and the operatorsability to perform the test in a consist

36、ent manner. Key steps that directly reflect the importance of operator skill include the angleand rate of tape removal and the visual assessment of the tested sample. It is not unexpected that different operators might obtaindifferent results (1, 2).5.6 The standard requires that the free end of the

37、 tape be removed rapidly at as close to a 180 angle as possible. When the peelangle and rate vary, the force required to remove the tape can change dramatically due to the rheological properties of the backingand adhesive. Variation in pull rate and peel angle can effect large differences in test va

38、lues and must be minimized to assurereproducibility (3).NOTE 1These test methods have been reported being used to measure adhesion of organic coatings on non-metallic substrates (for example, woodand plastic), although related precision and bias data is lacking. If testing coatings on non-metallic s

39、ubstrates, either Test Method A or Test Method Bmay be more appropriate and the method employed should be discussed by interested parties. Issues with plastic substrates are noted in Appendix X1.Asimilar test method, ISO 2409, permits tests on non-metallic substrates (for example, wood and plaster).

40、 Precision and bias data on the latter is lacking.Test Method D3359 was developed with metal as the substrate and, in the absence of supporting precision and bias data, is so limited.TEST METHOD AX-CUT TAPE TEST6.

Refer to X1.5 for additional informationNOTE 4Permacel P99 tape, previously identified as suitable for this purpose, was withdrawn from manufacture in July 20

46、09. Current supplies ofPermacel 99 on the market at this time have a shelf life that runs out in July 2010. Subcommittee D01.23 is assessing alternative tapes and a newinterlaboratory study is planned to take place in 2010. Alternative tapes with specifications similar to that of Permacel P99 tape a

47、re available. Users ofalternative tapes should check whether the alternative tapes give comparable results to the Permacel P99 tape.
