1、Designation: D3359 091D3359 0912Standard Test Methods forMeasuring Adhesion by Tape Test1This standard is issued under the fixed designation D3359; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A number

2、 in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense.1NOTEFootnote 5 and 5.2 were corrected editorially in June 2010.Footnote

Scope*1.1 These test methods cover procedures for assessing the adhesion of coating films to metallic substrates by applying andremoving pressure-sensiti

4、ve tape over cuts made in the 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 inAppendix X1.Asimilar test method, ISO 2409, permits tests on soft substrates (f

5、or example, wood and plaster).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 MethodAis primarily intended for use at job sites while Test Method B is more s

6、uitable for use in the laboratory.Also,Test Method B is not considered suitable for films thicker than 5 mils (125m).NOTE 2Subject to agreement between the purchaser and the seller, Test Method B can be used for thicker films if wider spaced cuts are employed.1.3 These test methods are used to estab

7、lish whether the adhesion of a coating to a substrate is at a generally adequate level.They do not distinguish between higher levels of adhesion for which more sophisticated methods of measurement are required.NOTE 3It should be recognized that differences in adherability of the coating surface can

8、affect the results obtained with coatings having the sameinherent adhesion.1.4 This test method is similar in content (but 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 deter

Summary of Test Methods3.1 Test Method AAn X-cut is made through the film to the

18、substrate, pressure-sensitive tape is applied over the cut and thenremoved, and adhesion is assessed qualitatively on the 0 to 5 scale.3.2 Test Method BA lattice pattern with either six or eleven cuts in each direction is made in the film to the substrate,pressure-sensitive tape is applied over the

19、lattice and then removed, and adhesion is evaluated by comparison with descriptionsand illustrations.4. Significance and Use4.1 If a coating is to fulfill its function of protecting or decorating a substrate, it must adhere to it for the expected service life.Because the substrate and its surface pr

20、eparation (or lack of it) have a drastic effect on the adhesion of coatings, a method toevaluate adhesion of a coating to different substrates or surface treatments, or of different coatings to the same substrate andtreatment, is of considerable usefulness in the industry.4.2 The limitations of all

21、adhesion methods and the specific limitation of this test method to lower levels of adhesion (see 1.3)should be recognized before using it. The intra- and inter-laboratory precision of this test method is similar to otherwidely-accepted tests for coated substrates (for example, Test Method D2370 and

22、 Test Method D4060), but this is partly the resultof it being insensitive to all but large differences in adhesion. The limited scale of 0 to 5 was selected deliberately to avoid a falseimpression of being sensitive.TEST METHOD AX-CUT TAPE TEST5. Apparatus and Materials5.1 Cutting ToolSharp razor bl

33、immersion, salt spray, or high humiditybefore conducting the tape test. The conditions and time of exposure will be governed by ultimate coating use or shall be agreed upon between thepurchaser and seller.3Available from American National Standards Institute (ANSI), 25 W. 43rd St., 4th Floor, New Yo

34、rk, NY 10036, http:/www.ansi.org.237. Procedure7.1 Select an area free of blemishes and minor surface imperfections. For tests in the field, ensure that the surface is clean anddry. Extremes in temperature or relative humidity may affect the adhesion of the tape or the coating.7.1.1 For specimens wh

35、ich have been immersed:After immersion, clean and wipe the surface with an appropriate solvent whichwill not harm the integrity of the coating. Then dry or prepare the surface, or both, as agreed upon between the purchaser and theseller.7.2 Make two cuts in the film each about 40 mm (1.5 in.) long t

36、hat intersect near their middle with a smaller angle of between30 and 45. When making the incisions, use the straightedge and cut through the coating to the substrate in one steady motion.7.3 Inspect the incisions for reflection of light from the metal substrate to establish that the coating film ha

37、s been penetrated.If the substrate has not been reached make another X in a different location. Do not attempt to deepen a previous cut as this mayaffect adhesion along the incision.7.4 At each day of testing, before initiation of testing, remove two complete laps of the pressure-sensitive tape from

38、 the roll anddiscard. Remove an additional length at a steady (that is, not jerked) rate and cut a piece about 75 mm (3 in.) long.7.5 Place the center of the tape at the intersection of the cuts with the tape running in the same direction as the smaller angles.Smooth the tape into place by finger in

39、 the area of the incisions and then rub firmly with the eraser on the end of a pencil. Thecolor under the transparent tape is a useful indication of when good contact has been made.7.6 Within 90 6 30 s of application, remove the tape by seizing the free end and pulling it off rapidly (not jerked) ba

40、ck uponitself at as close to an angle of 180 as possible.7.7 Inspect the X-cut area for removal of coating from the substrate or previous coating and rate the adhesion in accordancewith the following scale:5A No peeling or removal,4A Trace peeling or removal along incisions or at their intersection,

41、3A Jagged removal along incisions up to 1.6 mm (116 in.) on either side,2A Jagged removal along most of incisions up to 3.2 mm (18 in.) on eitherside,1A Removal from most of the area of the X under the tape, and0A Removal beyond the area of the X.7.8 Repeat the test in two other locations on each te

42、st panel. For large structures make sufficient tests to ensure that the adhesionevaluation is representative of the whole surface.7.9 After making several cuts examine the cutting edge and, if necessary, remove any flat spots or wire-edge by abrading lightlyon a fine oil stone before using again.

Precision and Bias49.1 In an interlaboratory study of this test method in which operators in six laboratories made one adhesion measurement onthree panels each of three coatings covering a wide range of adhesion, the within-laboratories standard deviation was found to be0

47、.33 and the between-laboratories 0.44. Based on these standard deviations, the following criteria should be used for judging theacceptability of results at the 95 % confidence level:9.1.1 RepeatabilityProvided adhesion is uniform over a large surface, results obtained by the same operator should bec

48、onsidered suspect if they differ by more than 1 rating unit for two measurements.9.1.2 ReproducibilityTwo results, each the mean of triplicates, obtained by different operators should be considered suspectif they differ by more than 1.5 rating units.9.2 Bias cannot be established for these test meth
