EN 15337:2007 (E) 4 1 Scope This European Standard 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 a
19、nd sealing threaded fasteners. This test method may also be used for other adhesives. The test is for ranking and quality 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 pur
20、poses. NOTE Numerical design data may be obtained from tests using the materials and configurations used in the actual structure. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. Fo
21、r undated references, the latest edition of the referenced document (including any amendments) applies. EN ISO 7500-1, Metallic materials Verification of static uniaxial testing machines Part 1: Tension/compression testing machines Verification and calibration of the force-measuring system (ISO 7500
22、1:2004) 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 EN ISO 7500-1, class 1. The machine shall be able to appl
23、y a compressive force directly or indirectly. An example of a jig for compression testing for use on a pure 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 testing machine. 4.3 No
24、n-adhering material sheet (e.g. polyethylene sheet). 5 Preparation of test specimens 5.1 General Assemble no less than five specimens for each test as described below. 5.2 Each specimen shall be comprised of a pin of diameter (20 ) mm and a slip collar (20 ) mm in inside diameter and 18 mm 0,05 mm i
25、n 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. EN 15337:2007 (E) 5 NOTE Unless there is a specific requirement to test the adhesive with a specific material, low-grade carbon-steel (complying with
26、 grade 2 of ISO 683-9) is generally used and has been found to be satisfactory. The cutting oil used in the manufacture of specimens and any corrosion protection agent shall be completely soluble in the solvents used for degreasing at room temperature and shall contain no lanolin. 5.3 Clean all pins
27、 and collars with suitable cleaning agents to degrease them and allow them to dry. The cleaning agents used shall not leave any visually detectable residue on the surface. Allow the pins and collars to attain (23 2) C for at least 30 min before proceeding further with assembling, or store them in a
28、desiccator at (23 2) C. When stored use degreased specimens within four days or discard (oxidation affects the test results after this period of time). In any case, take precautions to avoid contamination in subsequent handling. Do not prime or activate unless specified for the material to be tested
29、 (if the specimen is primed or activated, state this in the test report). 5.4 Pre-assemble pins and collars before application of the adhesive, to ensure a smooth and sliding fit. Disassemble the parts. Apply sufficient adhesive to the surface of each pin, beginning at one end, to completely cover a
30、 length corresponding to the width of the collar in its final position. Also apply sufficient adhesive to completely cover the interior of the collar. Slip the collar over the pin completely, with a helicoidal back-and-forth movement (this operation shall not take longer than 6 s). 5.5 Place the ass
31、embly vertically with the fillet upwards on a non-adhering material (e.g. polyethylene sheet) (Figure 3). Take care that the assembly is at the required temperature, and do not place on a hot or cold surface. 5.6 Before application of the adhesive, an activator may be applied as recommended by the m
32、anufacturer. 5.7 Cure the adhesive in accordance with the manufacturers instructions. At the end of the curing period, remove by wiping excess of uncured material from the surfaces of the pin-and-collar assemblies. 6 Procedure After allowing for cure and any predetermined environmental conditioning,
33、 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 between 1 mm/min and 2 mm/min. Record the maximum load in Newtons. Cal
34、culate the static shear strength , expressed in Megapascals, using the equation: = F/A (1) where F is the maximum load, in Newtons; A is the bond area, in square millimetres. Test no fewer than five specimens. The bond area shall be calculated from the dimensions of the pin-and collar assembly given
35、 in Figure 3, while the effective bond length derives to 16 mm from the nominal collar width by subtracting the length of both chamfers. EN 15337:2007 (E) 6 7 Precision The precision of this test method is not known because inter-laboratory data are not available. 8 Test report The test report shall
36、 include the following information: a) reference to this European Standard (EN 15337:2007); b) complete identification of the adhesive tested, including type, form, source, date manufactured and manufacturers code number; c) complete identification of the material used and the method of cleaning and
37、 surface preparation prior to bonding; d) adhesive-application and bonding conditions used in preparing the specimens; e) conditioning procedure used for the specimens prior to testing; f) number of specimens tested; g) crosshead speed; h) average value of the maximum load and the standard deviation
38、, as well as the average value and the standard deviation of the shear strength.
