1、Designation: D 3330/D 3330M 04Standard Test Method forPeel Adhesion of Pressure-Sensitive Tape1This standard is issued under the fixed designation D 3330/D 3330M; the number immediately following the designation indicates theyear of original adoption or, in the case of revision, the year of last rev

2、ision. A number in parentheses indicates the year of lastreapproval. A superscript epsilon (e) indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense.1. Scope1.1 These test methods cover the measurement of

3、the peeladhesion of pressure-sensitive tapes.1.1.1 Test Method A gives a measure of the adherence,when peeled at 180 angle, to a standard steel panel or to othersurface of interest for a single-coated tape.1.1.2 Test Method B gives a measure of the adherence to thebacking of a single-coated tape.1.1

4、.3 Test Method C gives a measure of the adherence ofdouble-coated tape to a standard steel panel or other surface ofinterest.1.1.4 Test Method D gives a measure of the adherence of therelease liner to the adhesive of either single- or double-coatedtape.1.1.5 Test Method E gives a measure of the adhe

5、rence of anadhesive transfer tape to a standard steel panel or other surfaceof interest.1.1.6 Test Method F gives a measure of the adherence, whenpeeled at 90 angle, to a standard steel panel or other surface ofinterest for a single-coated tape.1.2 These test methods provide a means of assessing the

6、uniformity of the adhesion of a given type of pressure-sensitiveadhesive tape. The assessment may be within a roll of tape,between rolls, or between production lots.1.3 Variations in either the tape backing or the adhesive, orboth, affect the response. Therefore, these test methods cannotbe used to

7、pinpoint the specific cause(s) of non-uniformity.1.4 These test methods may not be appropriate to test tapeshaving relatively stiff backings, stiff liners, or backings show-ing high stretch at low forces. These characteristics will resultin a high variability for the test response which is not a tru

8、eindication of the real nature of the adhesive bond.1.5 Values stated in either SI or inch-pound units are to beregarded separately as standard. The values stated in eachsystem may not be exact equivalents, therefore, each systemmust be used independently without combining values in anyway.1.6 This

9、standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.

Summary of Test Method4.1 Test Method ASingle-Coated Tapes, Peel Adhesion at180 AngleA strip of tape is applied to a standard test panel(or other surface of int

17、erest) with controlled pressure. The tapeis peeled from the panel at 180 angle at a specified rate, duringwhich time the force required to effect peel is measured.4.2 Test Method BAdhesion to Backing, Single-CoatedTapesAstrip of the tape under test is applied to a rigid panel.A strip of the tape und

18、er test is applied to the backing of thefirst strip of tape and tested for peel adhesion as described inTest Method A.4.3 Test Method CDouble-Coated Tapes:4.3.1 Face Side AdhesionThe double-coated tape is ad-hered to a stainless steel panel (or other surface of interest),liner side up. The liner is

19、removed and the exposed adhesivecovered with a strip of 0.025-mm 0.001-in. thick polyesterfilm. The resulting tape is then tested as described in TestMethod A.4.3.2 Liner Side AdhesionThe face side adhesive is ad-hered to a 0.025-mm 0.001-in. polyester film. The liner isremoved and the tape is appli

20、ed adhesive down to a stainlesssteel panel (or other surface of interest). Testing is conducted asdescribed in Test Method A.4.4 Test Method DAdhesion to LinerThe tape is adheredto a standard steel test panel with the liner side up. The liner ispeeled from the adhesive in the same manner as in peeli

23、gle-Coated Tapes, 90 PeelA stripof tape is applied to a standard test panel (or other surface ofinterest) with controlled pressure. The tape is peeled from thepanel at 90 angle at a specified rate, during which time theforce required to effect peel is measured.5. Significance and Use5.1 These test m

24、ethods are tools for quality assurance use.Given specific pressure-sensitive tape and a requirement interms of the minimum or maximum peel value expected forthis tape, the data from the test can be used in conjunction withacceptance criteria.5.2 Test Method A, B, C, E, or F can show the relative bon

25、dstrength of a given tape to one or more surfaces (material andtexture) as compared to the standard stainless steel panel.Substitution of representative samples of materials in questionfor the standard steel panel would suffice to do this.5.3 Test MethodsA, B, C, E or F cannot be used to comparetwo

26、pressure-sensitive tapes of the same type but of differentmanufacture for their ability to adhere to a surface. This isbecause the measured peel force is not normalized for a fixedarea of stress. The area under stress varies with backingstiffness and adhesive rheology (firmness). Two different tapes

27、seldom agree in these properties.5.4 Test Method D can show the amount of force required toremove a liner that covers the adhesive side of a tape at aspecified peel rate. The force will be different at other peelrates.5.5 These test methods may not provide design informationas there is usually no di

28、rect relationship between peel adhesionand any functional requirement.6. Apparatus6.1 Specimen CutterThe specimen cutter shall hold twosingle-edged razor blades in parallel planes, a precise distanceapart, to form a cutter of exact specimens widths. Two cutters,12- and 24-mm 0.05- and 1-in. cutting

29、width, shall beavailable. Appropriate alternates which will not cause edgedamage may be used.6NOTE 1The 12-mm 0.5-in. cutter shall consist of a 12-mm 0.5-in.thick by 220-mm 8-in. length aluminum bar stock 12-mm 0.05-in.wide. The edges for about 125 mm 5 in. from one end shall be slightlyrounded to f

30、orm a handle. The width of the bar for 75 mm 3 in. from theopposite end shall be narrowed to exactly 12 mm 0.5 in. minus thethickness of a single razor blade (one of two used as cutting edges). Therazor blades shall be held in position using side plates. The end of thecutter shall be cut away at 45

31、angle to expose the cutting edge at one endof the blades. The edges shall be separated by 12 6 0.10 mm 0.5 in. The24-mm 1-in. cutter shall follow the same description except the bar stockshall be 24.0 mm 1 in. and shall be narrowed exactly 24 mm 1 in.minus the thickness of a single razor blade.6.2 D

New panels should be cleanedprior to use as described in 11.1, except with ten washes of thefinal solvent. Between uses, the panel test surface shall beprotected from scratches an

34、d contamination, and the panelsstored at conditions described in Section 10.6.4 RollerMechanically or hand operated.6.4.1 Asteel roller 85 6 2.5 mm 3.25 6 0.1 in. in diameterand 45 6 1.5 mm 1.75 6 0.05 in. in width, covered withrubber approximately 6 mm 0.25 in. in thickness, having aShore scale A d

35、urometer hardness of 80 6 5. The surface shallbe a true cylinder void of any convex or concave deviations.The mass of the roller shall be 2040 6 45 g 4.5 6 0.1 lb.6These widths correspond to the primary metric (SI) units described in GuideD 5750. These so-called “modular metric” units are used throu

36、ghout the world,except for Europe. If it is desirable to test slightly different widths (for example, 25mm) of specimens than those described in 9.1, this should be noted (see 18.1.7) andcalculations must also account for the difference (see 17.1).D 3330/D 3330M 0426.4.2 No part of the apparatus sha

37、ll increase the mass of theroller during use. The roller shall move either mechanically orby hand at the rate of 10 6 0.5 mm/s 24 6 0.5 in./min. Amechanically operated roller is recommended for refereepurposes.NOTE 2A simple check to determine if the rubber surface is cylindri-cal is to wrap the rol

38、ler in a very thin paper (onionskin) and drag it acrossa flat glass plate on which is placed carbon paper, face up. The carbon rubsoff onto the thin paper wrapper to reveal high spots or hollows on therubber surface.6.5 Adhesion TesterA constant-rate-of-extension (CRE)tension tester shall be used. I

39、t is proposed to use an electronicmachine taking at least one reading per mm 0.1 in. of tapepeeled. The tester shall have two clamps with centers in thesame plane, parallel with the direction of the motion on thestressing clamp, and so aligned that they will hold thespecimen wholly in the same plane

43、be withMEK or acetone.7.2.3 Before selecting or using these solvents for cleaningtest panels, be sure to read and follow all precautions on thechemical Material Safety Data Sheets (MSDS) and consultwith Environmental, Health, and Safety (EHS) professionals.7.3 Cleaning MaterialAbsorbent, surgical ga

44、uze, cottonwool or tissue may be used. To be suitable, materials must belint-free during use, absorbent, contain no additives that aresoluble in the solvents listed in 7.2 and made exclusively fromvirgin materials.8. Sampling8.1 Acceptance SamplingSampling shall be in accordancewith Practice D 3715/

45、D 3715M.8.2 Sampling for Other PurposesThe sampling and thenumber of test specimens depends on the purpose of thetesting. Practice E 122 is recommended. It is common to test atleast five specimens of a particular tape. Test specimens shouldbe taken from several rolls of tape, and whenever possible,a

46、mong several production runs of tape. Strong conclusionsabout a specific property of a tape cannot be based on tests ofa single unit (roll) of a product.9. Test Specimen9.1 The specimen shall be 24-mm 1-in. wide. If thespecimen is of a different width, refer to Note 4. A toleranceof6 0.5 mm 61/64 in

47、. shall be allowed. The length shall beapproximately 300 mm 12 in.9.2 Discard at least three but no more than six outer wrapsof tape from the sample roll before taking the specimens fortesting.9.3 Remove one specimen per sample roll for each test to beperformed. Remove the specimen from a freely rot

48、ating roll atthe rate of 500 to 750 mm/s 20 to 30 in./s. Where width orother factors causing a high adherence to backing makes itimpossible to remove the specimen at the prescribed rate,remove it at a rate as close to 500 mm/s 20 in./s as possible.9.4 When tape is wider than 24 mm 1 in., specimens o

49、f thewidest specified width are to be cut from the center of a stripremoved from the roll in accordance with 9.3.9.5 Apply specimen within 5 min after unwinding.10. Conditioning10.1 Condition the sample rolls of tape in the standardconditioning atmosphere as described in Practice D 4332 for aperiod of not less than 24 h. Test at these conditions.(WarningThe tester should know that by prolonged han-dling heat is transmitted to the stainless steel test panel.Therefore, during
