    ASTM F607-2003(2008) Standard Test Method for Adhesion of Gasket Materials to Metal Surfaces《衬垫材料粘结到金属表面的粘附性的标准试验方法》.pdf

    1、Designation: F 607 03 (Reapproved 2008)Standard Test Method forAdhesion of Gasket Materials to Metal Surfaces1This standard is issued under the fixed designation F 607; 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 This test method provides a means of d

    3、etermining thedegree to which gasket materials under compressive loadadhere to metal surfaces. The test conditions described areindicative of those frequently encountered in gasket applica-tions. Test conditions may also be modified in accordance withthe needs of specific applications as agreed upon

    4、 between theuser and the producer. The maximum temperature recom-mended for this test method is 205C (400F).1.2 The values stated in SI units are to be regarded asstandard. The values in parentheses are for information only.1.3 This standard does not purport to address all of thesafety concerns, if

    5、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 Method3.1 The procedure described in this test method involvesplacing a specimen of a gasket material between flat platens ofthe desired metal, loading the assembly, and subjecting it to aspecified set of cond

    7、itions. The tensile force required to part theplaten is measured in newtons or pounds-force and is recordedalong with the calculated stress (force per unit area) inmegapascals or pounds-force per square inch of gasket surface.NOTE 1This tensile force required to separate the platens may be inexcess

    8、of 8896 N (2000 lbf).NOTE 2This fixturing also provides for the measurement of creeprelaxation in accordance with Method B of Test Methods F38.4. Significance and Use4.1 This test method provides terms such as megapascals orpounds-force per square inch of gasket surface for expressingthe extent of a

    9、dhesion applicable to all materials within thescope of Classification System F 104. Under certain condi-tions, adhesion develops when gasket materials are confined ina compressed state between metal flanges. Adhesion is impor-tant as an index of ease of removal of a gasket material. Sinceother varia

    10、bles may enter into the performance in an applica-tion, the results obtained should be correlated with field results.Atypical set of conditions is described in this test method. Thistest method may be used as an acceptance test when agreedupon between the user and the producer.5. Apparatus5.1 Circul

Test Specimens6.1 Three circular test specimens of material shall be tested.Care should be taken to cut cleanly, with minimum burrs orloose fibers. The

    18、surface of the material shall be kept clean,free of oil deposits or foreign material. No substances shall beused during the cutting operation for lubrication of the die orfor any other purpose where they may come in contact with thespecimen. Specimens shall be cut with an inside diameter of32.25 to

    19、32.31 mm (1.270 to 1.272 in.) and an outside diameterof 51.7 to 51.9 mm (2.035 to 2.045 in.).6.2 The metal platens to be used in the test shall be preparedby removing all traces of previously tested gasket material. The8/0 dry garnet paper, which has been fastened to a hard, smoothsurface with the g

    20、rit side facing up and held in a horizontalposition, shall be used to provide the platen finish. The metalplaten shall be firmly grasped or held by means of a suitableholder and the surface to be finished shall be rubbed against thegarnet paper. A reciprocating motion shall be used in a patternof a

    21、figure eight and shall be continued until the platen has auniform finish. If a serrated or non-standard platen surface isused then a soft bronze brush may be used for cleaning, and insuch cases the surface finish should be measured using asuitable device prior to the next test. The platen shall then

    22、 bewashed clean with a laboratory grade of acetone to completethe removal of any foreign substance. Care should be takenafter cleaning the platens to handle them by the edge prior toassembly for test. See 8.1 for time limitation after cleaning.7. Conditioning7.1 Condition the cut specimens in accord

    23、ance with theprocedure described for their classification in accordance withClassification System F 104. The conditioning may be modi-fied in accordance with the needs of specific applications asagreed upon between the user and the producer.NOTEThe platens are flat, circular plates of the designated

    24、 metal having a diameter of 76 mm (3 in.) and a minimum thickness of 25.4 mm (1 in.).A hole 10.3 mm (0.405 in.) in diameter shall be drilled through the center of each platen. The platens shall be chamfered slightly on all edges. Both sidesshall be machined sufficiently to assure good parallelism of

    25、 the surfaces. One side of each platen shall be finished to a profile of 60 in. Ra(Roughnessabsolute) maximum (gasket side) utilizing a uniform finishing procedure as agreed upon by the participating laboratories.FIG. 1 Composite Test Assembly for Adhesion of Gasket Materials to Metal SurfacesF 607

    26、03 (2008)27.2 Hold the test fixture assemblymetal platens, cali-brated bolt, washer, and nut at 21 to 27C (70 to 80F) for aperiod of at least 4 h immediately prior to assembly.8. Procedure8.1 Assemble the platens within 30 min after cleaning withthe conditioned gasket specimens to form a sandwich wi

    27、th thespecimen carefully centered between the platens. Care shouldbe taken that the dowel pin holes in one platen are positioned90 apart from the dowel pin holes in the second platen.8.2 Lubricate the washer and the threads of the calibratedbolt very lightly, using molybdenum disulfide in powder ors

    28、pray form. (Oil is not recommended.) Carefully insert the boltthrough the two platens, the gasket, and the washer, andscrew on the nut finger tight. Take care to avoid contaminationof either the gasket or platen surface with the lubricant.8.3 After placing the box wrench in position on the nut,screw

    29、 the dial indicator assembly onto the end of the calibratedbolt, finger tight, and set the indicator needle at the zeroreading.8.4 Apply the desired stress to the specimens by tighteningthe nut with the box wrench until the required dial indicatorreading is reached. Record the actual dial indicator

    30、reading(Do). Apply this stress in one continuous motion with amaximum loading time of 3 s. A bolt elongation of 0.1222 to0.1270 mm (0.00481 to 0.0050 in.) is typical for a compressiveforce of 26.7 kN (6000 lbf). In the case of Type 2 or Type 3gasket material, a lighter compressive force as may be ag

    32、o 60 % relative humidity and 21 to 27C (70 to80F) ambient environment. A fan should cool the assembly in1h.8.8 Reassemble the box wrench and dial indicator in accor-dance with 8.3.8.9 Loosen the nut without disturbing the dial indicatorassembly. Record the dial indicator reading (Df).8.10 If desired
