18、ped partsWARNING 1 Persons using this document should be familiar with normal laboratory practice. This document does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user to establish appropriate safety and health practices and to e

19、nsure compliance with any national regulatory conditions.WARNING 2 Certain procedures specified in this document might involve the use or generation of substances, or the generation of waste, that could constitute a local environmental hazard. Reference should be made to appropriate documentation on

20、 safe handling and disposal after use.1 ScopeThis document specifies a method for the determination of the static vulcanized adhesion strength of rubber compounds to rigid materials. The test piece is composed of two conical ends of the rigid material, joined by a cylinder of rubber.The adhesion is

21、obtained by a bonding system which can include not only the rigid material and the rubber compound, but other elements such as thin alloy coatings or chemical treatments of rigid parts and either a single cement or both primer and cover cements. The bonding system for preparing the test pieces shoul

22、d be adequately specified by the user, but provision is made in this document for the evaluation of different types of failure related to a complex bonding system.The method is designed primarily for test pieces prepared in the laboratory under standard conditions in order to provide data for develo

23、pment and control of bonding systems and their components, such as cements or special rubber compounds, and of methods of manufacture. While intended to be applied where the rubber is bonded to rigid supporting pieces, it might not cover such cases where the support, although of high-modulus materia

24、l, has a low rigidity due to small transverse dimensions, as in the case of rubber bonded to metal wires, cords or thin sheets.2 Normative referencesThe following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document.

28、 the rupture of a test piece of standard dimensions, comprising a cylinder of rubber bonded to two rigid conical parts.The particular geometry of the test piece produces in most cases an interfacial failure between the cylinder of rubber and the conical parts because of a stress concentration at the

29、 tip of the cones.5 Apparatus5.1 Tensile-testing machine, complying with the requirements of ISO 5893:2002, class 2, and with a rate of traverse of the moving grip of (50 5) mm/min.Inertia (pendulum) type dynamometers have a tendency to give results which differ because of inertial effects. A low-in

30、ertia type dynamometer (for example, using an electronic or optical transducer) gives results which are free from this effect, and is therefore to be preferred.5.2 Fixtures, for holding the test pieces in the test machine, which permit accurate centring of the applied load during the test.6 Calibrat

31、ionThe test apparatus shall be calibrated in accordance with Annex A.7 Test piece7.1 Form and dimensionsThe standard test piece (see Figure 1) is formed by two rigid cylindrical parts terminated by opposite conical ends, and a cylinder of rubber bonded to the conical ends. The determination of the d

32、imensions of the test piece shall be in accordance with ISO 23529.The diameter of this cylinder and of the cylindrical portion of the rigid parts shall be (25 0,5) mm. The distance between the tips of the conical ends shall be (12 1) mm. The half-angle of the cone vertex shall be 45 1 and the tip sh

33、all be rounded to a radius not greater than 0,8 mm.The cylindrical portion of each rigid part shall be not less than 5 mm in length and shall be terminated so as to match with the holding jaws (5.2) of the test machine (5.1).7.2 MaterialsThe materials used shall conform to the specifications for the

34、 bonding system to be investigated. If no specification is given for the material of the rigid parts, they shall be made from low-carbon steel bars and their conical ends shall be grit-blasted.2 ISO 2017 All rights reservedBS ISO 5600:2017ISO 5600:2017(E)Dimensions in millimetresKey1 rubber cylinder

35、2 rigid conical partsFigure 1 Standard test piece7.3 Preparation7.3.1 Clean the surfaces of the conical ends or treat in accordance with the bonding system under investigation and, if so specified, coat with primer and/or cover cement. Spread the adhesive coating over the conical area only.7.3.2 Dur

36、ing the preparation of the test pieces, take great care when handling the materials to keep the bonding interfaces between the rubber and the rigid parts free from dust, moisture and foreign matter. Do not touch the treated conical surfaces with the hands during assembly.7.3.3 Vulcanize the test pie

37、ces in a suitable transfer mould, properly insulated and provided with heaters and compression devices. Place the rigid parts and the rubber compound in the preheated mould for vulcanization. Use sufficient unvulcanized compound to fill the pot and provide some excess after filling the mould cavitie

38、s.The mould design should take account of the fact that machining the rigid parts for reuse will gradually reduce their size.7.3.4 Carry out the vulcanization under the specified conditions of time, temperature and pressure.7.3.5 At the conclusion of the cure, take great care when removing the test

39、pieces from the mould to avoid subjecting the bonded surfaces to undue stress before the test pieces have cooled.7.4 Number of test piecesPrepare and test a minimum of three test pieces.7.5 Conditioning of test piecesCondition the test pieces in accordance with the requirements of ISO 23529 for at l

40、east 16 h at a standard laboratory temperature of (23 2) C or (27 2) C. Use the same temperature throughout the test and throughout a series of tests intended to be comparable.

41、e tensile-testing machine (5.1). Take extreme care in centring and adjusting the test piece so that the tension is symmetrically distributed over the cross-section of the test piece during the test.8.2 Apply the tension by separating the jaws at a constant rate of (50 5) mm/min until the test piece

42、breaks. Record the maximum force.8.3 Recover the broken pieces and examine the failure surfaces.8.4 Repeat for the remaining test pieces.9 Expression of results9.1 Adhesion valueExpress the adhesion value, in newtons, required to produce failure. In cases where the failure is in the rubber bulk, the

43、 adhesion value is recognized as being higher than that recorded.9.2 Type of adhesion failureExpress the type of adhesion failure, as determined by examination of the broken test pieces, by one or more of the following symbols:R failure in the rubber bulk;RC failure at the rubber/cover cement interf

44、ace;CP failure at the cover cement/primer cement interface;M failure at the metal/primer cement interface.Each symbol shall be followed by the percentage of the conical surface involved in that type of failure, estimated to the nearest 5 %.NOTE The estimated percentage of the various types of failur

45、e can be expressed as in the following examples:R 50, RC-50 means that roughly 50 % of the failure was in the rubber and the other 50 % at the rubber/cover cement interface.R 25, RC-25, M-50 means three types of failure were present, with the M indicating that 50 % of the failure was at the metal/pr

46、imer cement interface.10 Salvaging of bonded metal partsBonded metal parts can be salvaged by the usual burning or chemical stripping techniques. Mechanical or chemical surface treatments can be used to re-establish a clean bonding surface.The sharpness of the conical tip can be reduced during salva

47、ging; this affects the reproducibility of the test results, and care shall be taken to re-establish the sharpness of the cone to a radius of 0,8 mm or less.4 ISO 2017 All rights reservedBS ISO 5600:2017ISO 5600:2017(E)11 Test reportThe test report shall include the following information:a) sample de
