The work of preparing International Standards is normally carried out through

6、 ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborate

7、s closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval cri

13、This International Standard does not purport to address all of the safety concerns, 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 regulatory requirements. 1 Scope This International Standar

14、d specifies a method for the determination of the shear strength of anaerobic- curing liquid adhesives used for retaining cylindrical assemblies, pin-and-collar type, or for locking and sealing threaded fasteners. This test method can also be used for other adhesives. The test is for ranking and qua

15、lity control of adhesives. The result does not necessarily reflect the performance of the materials in service and the test is not suitable for providing numerical data for design purposes. NOTE Numerical design data can be obtained from tests using the materials and configurations used in the actua

16、l structure. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (includ

17、ing any amendments) applies.

18、ce-measuring system 3 Principle The force required to shear the adhesive joint formed between a metal pin and a metal collar is determined. The static shear strength is calculated from this force. 4 Apparatus 4.1 Universal testing machine, complying with ISO 7500-1, class 1. The machine shall be abl

19、e to apply a compressive force directly or indirectly. An example of a jig for compression testing, which can be used to adapt a tensile testing machine, is shown in Annex A. 4.2 Test specimen support, made of hardened steel, as shown in Figure 1, for positioning the test specimen on the universal t

20、esting machine. 4.3 Non-adhering material sheet, e.g. polyethylene sheet. ISO 2013 All rights reserved 1 ISO 10123:2013(E) 5 Preparation of test specimens Assemble not less than five specimens for each test as described below. 5.1 Each specimen shall be comprised of a pin of diameter ( ) mm and a sl

21、ip collar ( ) mm in inside diameter and (18,00 0,05) mm in width, both components being finished to 0,8 m to 1,6 m (see Figure 2). The material used for the collar and pin shall be stated in the test report. NOTE Unless there is a specific requirement to test the adhesive with a specific material, l

22、ow-grade carbon steel (complying with grade 2 of ISO 683-9) is generally used and has been found to be satisfactory. The cutting oil used in the manufacture of the specimens shall be soluble in the degreasing solvents at room temperature and shall contain no lanolin. The corrosion protection materia

23、ls shall also be soluble in the degreasing solvents at room temperature. 5.2 Clean all pins and collars with a suitable cleaning agent to degrease them and allow them to dry. The cleaning agents used shall not leave any visually detectable residue on the surface. The pins and collars shall be stored

24、 at (23 2) C for at least 30 min before assembly, or store them in a desiccator at (23 2) C. After cleaning, use the degreased specimens within 4 d or discard them (oxidation affects the test results after this period of time). Take precautions to avoid contamination during subsequent handling. Do n

25、ot prime or activate the surface unless specified for the material under test. If the specimen is primed or activated, state this in the test report. 5.3 Pre-assemble pins and collars before application of the adhesive to ensure a smooth and sliding fit. Disassemble the parts. Apply sufficient adhes

26、ive to the surface of each pin, beginning at one end, to completely cover a length corresponding to the width of the collar in its final position. Also apply sufficient adhesive to completely cover the interior of the collar. Before application of the adhesive, an activator can be applied as recomme

27、nded by the manufacturer. Slip the collar over the pin completely, with a helicoidal back-and-forth movement (this operation shall not take longer than 6 s). 5.4 Place the assembly vertically, with the fillet upwards, on a sheet of non-adhering material (e.g. polyethylene) as shown in Figure 3. Ensu

28、re that the assembly is at the required temperature and do not place it on a hot or cold surface. 5.5 Cure the adhesive in accordance with the manufacturers instructions. After curing, wipe the excess of the surfaces of the pin-and-collar assemblies to remove any uncured adhesive. 6 Procedure After

29、allowing for cure and any predetermined environmental conditioning, determine the static shear strength as follows. Place the pin-and-collar assembly in the steel specimen support and place the support on the test device (see Figure 4). Load the specimen smoothly using a constant crosshead speed bet

30、ween 1 mm/min and 2 mm/min.2 ISO 2013 All rights reserved ISO 10123:2013(E) Record the maximum load in Newtons. Calculate the static shear strength , expressed in megapascals, using Formula (1): (1) where F is the maximum load, in Newtons; S is the bond area, in square millimetres. The bond area sha

31、ll be calculated from the dimensions of the pin-and-collar assembly given in Figure 3. The effective bond length is calculated as 16 mm, from the nominal collar width, subtracting the length of both chamfers. Test no fewer than five specimens. 7 Precision The precision of this test method is not kno

32、wn because interlaboratory data are not available. 8 Test report The test report shall include the following information: a) a reference to this International Standard, i.e. ISO 10123; b) complete identification of the adhesive tested, including type, form, source, date manufactured and manufacturer

33、s code number; c) complete identification of the material used and the method of cleaning and surface preparation prior to bonding; d) the adhesive-application and bonding conditions used in preparing the specimens; e) the conditioning procedure used for the specimens prior to testing; f) the number

34、 of specimens tested; g) the crosshead speed; h) the average value of the maximum load and the standard deviation, as well as the average value and the standard deviation of the shear strength.
