17、ISO 813:2016(E)Rubber, vulcanized or thermoplastic Determination of adhesion to a rigid substrate 90 peel methodWARNING 1 Persons using this International Standard should be familiar with normal laboratory practice. This International Standard does not purport to address all of the safety problems,

18、if any, associated with its use. It is the responsibility of the user to establish appropriate safety and health practices and to ensure compliance with any national regulatory conditions.WARNING 2 Certain procedures specified in this International Standard may involve the use or generation of subst

19、ances, or the generation of waste, that could constitute a local environmental hazard. Reference should be made to appropriate documentation on safe handling and disposal after use.1 ScopeThis International Standard specifies a method for the determination of the adhesive strength of a vulcanized or

20、 thermoplastic rubber bonded to a rigid substrate, using a test piece comprising a strip of rubber bonded to a single plate of rigid material. The test is carried out at a peel angle of 90.The method is applicable primarily to test pieces prepared in the laboratory under standard conditions, such as

28、the tolerances given in ISO 23529.5 Test pieces5.1 DimensionsThe standard test piece shall consist of a strip of rubber 6 mm 0,1 mm thick in the test area, 25 mm 0,1 mm wide and 125 mm long, bonded to a square area, 25 mm long and 25 mm 0,1 mm wide on the surface of a strip of rigid substrate, the d

29、etermination of the dimensions of the test piece being in accordance with ISO 23529.The substrate shall be sufficiently thick to prevent deformation during the test: a minimum thickness of 1,5 mm is recommended. The width shall be 25 mm 0,1 mm and the length, 60 mm 1 mm.Each test piece shall be prep

30、ared so that the bonded area, 25 mm long and 25 mm 0,1 mm wide, is approximately in the middle of the substrate as shown in Figure 2.2 ISO 2016 All rights reservedBS ISO 813:2016ISO 813:2016(E)Dimensions in millimetresKey1 rubber2 masked area3 bonded area4 rigid substrate5 thickness depends on the t

31、hickness of the substrateFigure 2 Standard test piece5.2 Preparation5.2.1 Two types of mould can be used for the preparation of test pieces: moulds for several test pieces or moulds for single test pieces.5.2.1.1 When test pieces are to be made using one type of rubber and one type of adhesive syste

32、m, a mould for several test pieces can be used. The inside mould dimension parallel to the longitudinal axis of the strip of substrate shall be 125 mm. The dimension corresponding to the transverse axis of the strip of substrate can be altered, depending on the number of test pieces to be prepared a

33、t a time. The dimension perpendicular to the longitudinal and transverse axes of the substrate can be altered, for instance using metal plates of various thicknesses, depending on the thickness of the substrate, in order to leave a depth of 6 mm 0,05 mm free for the rubber.5.2.1.2 When only one test

34、 piece is to be made from a given rubber, a mould as specified in 5.2.1.1 shall be used, except that the dimension corresponding to the transverse axis shall be restricted to the width of the test piece.5.2.2 From the rubber compound, cut slabs of sufficient thickness and of the required size for th

35、e mould (length 125 mm, width corresponding to the number of test pieces to be prepared) so as to ensure maximum pressure between the rubber and the substrate during the test piece preparation process. ISO 2016 All rights reserved 3BS ISO 813:2016ISO 813:2016(E)5.2.3 During test piece preparation, t

36、ake great care to keep the surfaces to be bonded clean and free from dust, moisture and other foreign matter.Prepare, in the way required by the adhesive system under investigation, the surface to be bonded of strips of substrate of the dimensions specified in 5.1. Mask both ends with pressure-sensi

37、tive tape so that only the area specified in 5.1 is available for bonding.Clean the rubber surface to be bonded, using solvent or another technique as required by the adhesive system under investigation.Apply the adhesive and assemble the strips of substrate and rubber. Place the assembly in the mou

38、ld, with the substrate at the bottom. When more than one test piece is being prepared at a time, place the strips of substrate approximately 3 mm apart to permit subsequent separation of the test pieces.5.2.4 In the case of a rubber bonded with a heat-curing adhesive, carry out the vulcanization and

39、/or bonding by heating the mould under pressure in a suitable press for the time and at the temperature required by the system being investigated.Take great care when removing the test pieces from the mould to avoid subjecting the bonded surfaces to undue stress before the test pieces have cooled.NO

40、TE When the substrate used is a thermoplastic material, the strip may, in some cases, need to be raised to a temperature above its softening point in order to ensure adhesion. When the substrate is a thermosetting polymer, the starting material may, in some cases, be a low-viscosity prepolymer at th

41、e test piece preparation temperature, whose polymerization is completed during the process. The mould and the moulding pressure will have to be adapted to such cases.5.2.5 When more than one test piece is prepared at a time, separate the test pieces from each other for testing. Do this by cutting wi

42、th scissors, a knife or another suitable tool. The edges of each test piece can then be buffed on a belt sander to bring the edge of the rubber flush with the edge of the substrate. Take care not to overheat the test piece and not to reduce the width of the test piece beyond the tolerance allowed.5.

43、2.6 The test can also be used to measure post-vulcanization (PV) bonding, where preformed vulcanized rubber is bonded to the substrate. The conditions of bonding, such as temperature, pressure and surface preparation, shall be given in the test report.5.3 NumberFour test pieces shall be tested.5.4 C

44、onditioning before testingThe time interval between the preparation of the test pieces and testing shall be in accordance with the requirements of ISO 23529. It shall be at least 16 h after moulding.Condition the test pieces in accordance with the requirements of ISO 23529 for at least 16 h at a sta

45、ndard temperature (23 C 2 C or 27 C 2 C) immediately before the test.When a test at other than standard laboratory temperature is required, carry out additional conditioning at this temperature for long enough to bring the material to the required temperature. ISO 23529 gives guidance on the conditi

46、oning time necessary to reach temperature equilibrium.6 Test temperature and humidityUnless otherwise specified, carry out testing at standard laboratory temperature, as specified in ISO 23529.4 ISO 2016 All rights reservedBS ISO 813:2016ISO 813:2016(E)When other test temperatures are required, take

47、 them, as far as possible, from the list of preferred temperatures given in ISO 23529.Use the same temperature throughout any one test, as well as any series of tests intended to be comparable.7 Procedure7.1 Place the test piece symmetrically in the fixture (4.2), with the end to be pulled apart fac

48、ing towards the operator. Before applying the load, strip the rubber from the substrate for a distance of about 2 mm, using a sharp knife and taking care not to introduce tears in the rubber. Place the free end of the rubber strip in the grip (4.3). In the case of tests at other than standard temper

49、ature, keep the test piece in the temperature-controlled chamber (4.4) for a sufficient length of time after closure of the chamber for the test piece to reach the required temperature. Then move the grip of the tensile-testing machine at 50 mm/min 5 mm/min until separation is complete. Record the maximum force required to cause separation.Other speeds of separation may be used to examine the viscoelastic behaviour of the bond (see Annex A). In such cases, the use of logarithmic incremen
