1、Designation: D 413 98 (Reapproved 2007)Standard Test Methods forRubber PropertyAdhesion to Flexible Substrate1This standard is issued under the fixed designation D 413; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of la
2、st revision. A number in parentheses indicates the year of last reapproval. Asuperscript 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 determina
3、tion of theadhesion strength between plies of fabric bonded with rubberor the adhesion of the rubber layer in articles made from rubberattached to other material. They are applicable only when theadhered surfaces are approximately plane or uniformly circularas in belting, hose, tire carcasses, or ru
4、bber-covered sheetmetal.1.2 When the adhered surfaces contain sharp bends, angles,or other gross irregularities that cannot be avoided in preparingtest specimens, special test methods must be employed forevaluating adhesion.1.3 The values stated in SI units are to be regarded as thestandard. The val
5、ues given in parentheses are for informationonly.1.4 This standard does not purport to address all of thesafety problems, 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 re
6、gulatory limitations prior to use.2.

7、ized SheetsD 3183 Practice for RubberPreparation of Product Piecesfor Test Purposes from Products3. Summary of Test Method3.1 Two general test methods are given:3.1.1 Static-Mass Method, in which the force required tocause separation between adhered surfaces is applied by meansof gravity acting on a
8、 mass.3.1.2 Machine Method, in which the force required to causeseparation between adhered surfaces is applied by means of atension machine.3.2 Except as may be otherwise specified in these testmethods, the requirements of Practices D 3182 and D 3183,shall be complied with and are made a part of the
9、se testmethods.3.3 In case of conflict between the provisions of these testmethods and those of detailed specifications or test methods fora particular material, the latter shall take precedence.3.4 As covered by these test methods, an adhesion testconsists of applying to a test specimen, under spec
10、ifiedconditions, a (measured) force sufficient to strip from thespecimen at a measured rate, a layer of moderate thicknesswith separation (rupture, tearing) at the adhered surfaces. Thenumerical value of the adhesion is expressed as (1) the averageforce required to cause separation at a definite rat
11、e, or (2) theaverage rate of separation caused by a known or specifiedforce. In the machine test method, the rate of separation is fixedand the adhesion value must be expressed in terms of themeasured force. With the static-mass test method, either (1)or(2) can be used, but the latter is preferable
12、and will be hereemployed.4. Significance and Use4.1 These test methods are used to ensure the quality of aproduct by determining the force per unit width required toseparate a rubber layer from a flexible substrate such as fabric,fibre, wire, or sheet metal. The acceptable value of adhesionmeasured
13、will, of course, vary from product to product due todifferent rubber formulations, flexible substrates, and types ofproducts. However, once a product is established, minimumvalues of separation force can be determined and agreed to byproducer and consumer and both can monitor to assuremaintenance of
14、 the agreed-upon minimum value.1These test methods are under the jurisdiction of ASTM Committee D11 onRubber and are the direct responsibility of Subcommittee D11.25 on RubberAdhesive Systems.Current edition approved Nov. 1, 2007.

17、ETHOD5. Apparatus5.1 The apparatus required for the adhesion test by thestatic-mass test method consists of a supporting frame, testingclamps, mandrels, calibrated masses, and mass carriers. Thesupporting frame is of such design that clamps for stripspecimens hang on it vertically and that mandrels
18、for ringspecimens are supported on it horizontally. The frame hassufficient height to permit the mass carrier to be suspendedfrom the test specimens by means of clamps and to hang freelyduring the progress of the test. Provision also is made tosupport the mandrels so that they revolve freely with mi
19、nimumfriction. Suitable apparatus is shown in Fig. 1 and Fig. 2.6. Test Specimens6.1 Strip SpecimensType APlane strips having a widthof 25 + 3, 0 mm (1 + 0.125, 0 in.), and a minimum lengthsuch as to permit 180 peel separation over sufficient distanceto indicate the adhesion value.6.1.1 Cut the spec
20、imen to 25 + 3, 0 mm (1 + 0.125 0in.) wide. The thickness will vary according to the constructionof the article being tested. The maximum thickness of thespecimen is limited to 13 mm (0.5 in.). To comply with thisrequirement, slice or buff the specimen. The ply or layer beingseparated should never b
21、e over 6.5 mm (0.25 in.) thick.6.1.2 Cut the specimen from the article in such a mannerthat the adhered parts have the same width where practicable.The technique used in 6.2.2 and 6.2.3 may be applied here.When necessary, or specified, cut only the layer to be separated(by application of load) to th
22、e prescribed width. In such cases,remove the portions of that layer remaining outside of the testwidth to avoid edge constriction during separation.6.1.3 Curved specimens for test in strip form shall havecurvature only in the length dimension of the specimen.6.2 Strip SpecimensType BThe same as Type
23、 A, withthe exception of 90 peel and the separation line in the centerof the specimen.6.2.1 Cut the specimen 35 mm (138 in.) wide. Remove theexcess plies to obtain a thickness of 6 mm (14 in.) and leave theseparation line in the center of the specimen to ensure a 90peel.6.2.2 Buff to a width of 30 m
24、m (118 in.) with a coarse gritemery cloth (grit No. 40) with care to prevent burning orgumming the sides of the specimen.6.2.3 Make a 2-mm (116-in.) deep slit with a knife alongeach side exactly where the specimen is to be separated duringtesting. Use a knife with an adjustable blade where only thed
25、esired depth of cut (2 mm) of blade is exposed.6.3 Ring SpecimensClosed rings having a width of 25 mm(1 in.) and maximum internal diameter of 100 mm (4 in.).6.3.1 Mount the article on a smooth, close-fitting, slightlytapered wooden mandrel.6.3.2 Rotate the mandrel (a lathe is preferred) and cut25-mm
26、 (1-in.) wide ring sections by forcing a sharp pointedknife gradually through the article.6.3.3 Cut rings with internal diameters over 100 mm (4 in.)through and open to form strip specimens.7. Procedure7.1 Strip Specimen: Type A, 180 PeelMeasure the widthof the strip cut to the nearest 0.2 mm (0.01

Apparatus8.1 A tension testing machine, power-driven, accurate towithin 61 % is used for me
36、asuring the force required toseparate the layers of the test specimen. A constant rate ofextension testing machine satisfies this condition and is pre-ferred although an inclination-balance, pendulum-type, or aspring-balance apparatus may be used. Requirements of thetesting machine are in 8.2.1 to 8
37、.2.5.8.2 Testing Machine:8.2.1 The testing machine shall be capable of being operatedwithout any device for maintaining maximum load indication.For pendulum-type machines, do not engage pawls that preventthe mass lever from swinging freely.8.2.2 The machine shall be equipped with the chart wherethe
38、distance separated is one axis and the applied force is theother axis of coordinates. The preferred chart speed is the sameas the cross-head speed for ring specimens and one half thecross-head speed for strip specimens.8.2.3 The force applied shall be greater than 15 % and lessthan 85 % of the capac
39、ity of the machine.8.2.4 GripsStrip specimens shall be held in the testingmachine by grips that clamp firmly and prevent slipping at alltimes during the test. For ring specimens, replace the gripattached to the recording head of the machine with a freelyrotating mandrel with an outside diameter subs
40、tantially thesame as the inside diameter of the ring specimen. Mount themandrel so that its axis of rotation is in the plane of the plybeing separated and the applied force is normal to the tangentof the ring circumference at the line of separation.8.2.5 The preferred rate of travel of the power-act
41、uated gripis 0.8 mm/s (2 in./min) for strip specimen TypeA, 2.5 mm/s (6in./min) for Type B, and 0.4 mm/s (1 in./min) for ringspecimens. These rates are to be uniform throughout the tests.9.

Provide for maintaining the stripduring the test approximately in the plane of the clamps. Thismay be done either by attaching the minimum mass required tothe free end of
45、the specimen or by holding the specimen againsta plate attached to the stationary clamp but, in either case, takeinto account the added mass in determining the force causingseparation. Grip that layer of the specimen of which theadhesion is to be tested symmetrically and firmly withouttwisting in th
