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 su
9、rfaces is applied by meansof gravity acting on a 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 D3182 and D3183,sha
10、ll be complied with and are made a part of these 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 testconsi
11、sts of applying to a test specimen, under specifiedconditions, 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
12、required to cause separation at a definite rate, 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
13、(2) can be used, but the latter is preferable and will be hereemployed.1These test methods are under the jurisdiction of ASTM Committee D11 onRubber and Rubber-like Materials and are the direct responsibility of SubcommitteeD11.25 on Rubber Adhesive Systems.Current edition approved Oct. 1, 2017.

Significanc
17、e 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 will, of course, vary from product to p
18、roduct 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 the agreed-upon minimum value.STATIC-M
19、ASS METHOD5. 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 mand
20、rels 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 wi
21、th minimumfriction. 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
22、 specimen 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 ne
23、ver be 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)
24、to the 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
25、 Type 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
26、 30 mm (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
27、 thedesired 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 cut
28、25-mm (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.

A constant rate ofextension testing machine satisfies this condition and is pre-ferred although an incli
38、nation-balance, pendulum-type, or aspring-balance apparatus may be used. Requirements of thetesting machine are in 8.2.1 to 8.2.5.8.2 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
39、not engage pawls that preventthe mass lever from swinging freely.8.2.2 The machine shall be equipped with the chart wherethe 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 h
40、alf thecross-head speed for strip specimens.8.2.3 The force applied shall be greater than 15 % and lessthan 85 % of the capacity 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 specime
41、ns, replace the gripattached to the recording head of the machine with a freelyrotating mandrel with an outside diameter substantially theFIG. 2 Mandrels and Frame for Static Mass Adhesion TestD413 98 (2017)3same as the inside diameter of the ring specimen. Mount themandrel so that its axis of rotat
42、ion 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-actuated 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
43、(1 in./min) for ringspecimens. These rates are to be uniform throughout the tests.9. Test Specimens9.1 Prepare the specimens in accordance with Section 6.10. Procedure10.1 Strip Specimens: Type A, 180 PeelMeasure thewidth of the cut strip to the nearest 0.2 mm (0.01 in.) andrecord. Separate the part
44、s to be tested by hand at one end of thetest specimen and at a sufficient distance to permit grips of themachine to be attached. Attach the separated end of thespecimen, with all separate parts except the one under testsecurely gripped, to the recording head by means of a clamp,using care to adjust
45、it symmetrically in order that the tensionshall be distributed uniformly. 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 the specimen or by holding the specimen againsta plate
46、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 the power-actuated clamp. Adjust the autographicmechanism
47、 and chart to zero and start the machine. Strip theseparating layer from the specimen at an angle of approxi-mately 180, and continue the separation for a sufficientdistance to indicate the adhesion value.10.2 Strip Specimen: Type B, 90 PeelSeparate by hand asufficient distance along the separation
48、line in the center of thestrip to permit the grips of the machine to be attached. Makeprovision to keep the unpeeled portion of the test specimen ina horizontal position using a plate if necessary to ensure a 90peel. Peel along the previously cut separation layer for 40 to100 mm (112 to 4 in.).10.3
49、Ring SpecimensSeparate by hand a sufficient lengthof a layer of the specimen to be tested to permit the power-actuated clamp of the machine to be attached. Place thespecimen snugly on the test mandrel. With the mandrelattached to the recording head of the machine and the separatedlayer gripped symmetrically and firmly without twisting in thepower-actuated clamp, adjust the autographic mechanism andchart to zero and start the machine. Strip the separating layerfrom the specimen at an angle of approximately 90 to thet
