12、 Foreword This document (EN 15337:2007) has been prepared by Technical Committee CEN/TC 193 “Adhesives”, the secretariat of which is held by AENOR. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by

13、March 2008, and conflicting national standards shall be withdrawn at the latest by March 2008. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent

14、 rights. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland

15、, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and the United Kingdom. Safety statement Persons using this document should be familiar with the principles of normal laboratory practices. This document does

16、 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 ensure compliance with any regulatory conditions. EN 15337:2007 (E) 4 1 Scope This European Standard specifies a method f

17、or 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 may also be used for other adhesives. The test is for ranking and quality control of adhesive

18、s. 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 may be obtained from tests using the materials and configurations used in the actual structure. 2 Normative

20、ification of static uniaxial testing machines Part 1: Tension/compression testing machines Verification and calibration of the force-measuring system (ISO 75001:2004) 3 Principle The force required to shear the adhesive joint formed between a metal pin and a metal collar is determined. The static sh

21、ear 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 apply a compressive force directly or indirectly. An example of a jig for compression testing for use on a pure tensile testing machine is shown

22、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 Non-adhering material sheet (e.g. polyethylene sheet). 5 Preparation of test specimens 5.1 General Assemble no less than five specimens for eac

23、h 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 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 tes

24、t 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 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

25、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 and collars with suitable cleaning agents to degrease them and allow them to dry. The cleaning agents used shall not leave any visually dete

26、ctable 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 desiccator at (23 2) C. When stored use degreased specimens within four days or discard (oxidation affects the test results after this period

27、 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 (if the specimen is primed or activated, state this in the test report). 5.4 Pre-assemble pins and collars before application of the adhesiv

28、e, 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 length corresponding to the width of the collar in its final position. Also apply sufficient adhesive to completely cover the interior of th

29、e 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 assembly vertically with the fillet upwards on a non-adhering material (e.g. polyethylene sheet) (Figure 3). Take care that the assembly is at t

30、he 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 manufacturer. 5.7 Cure the adhesive in accordance with the manufacturers instructions. At the end of the curing period, remove by wiping exces

31、s of uncured material from the surfaces of the pin-and-collar assemblies. 6 Procedure After 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

32、 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. Calculate the static shear strength , expressed in Megapascals, using the equation: = F/A (1) where F is the maximum load, in Newtons; A is the

33、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 in Figure 3, while the effective bond length derives to 16 mm from the nominal collar width by subtracting the length of both chamfers.

35、, including type, form, source, date manufactured and manufacturers code number; c) complete identification of the material used and the method of cleaning and surface preparation prior to bonding; d) adhesive-application and bonding conditions used in preparing the specimens; e) conditioning proced

36、ure 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, as well as the average value and the standard deviation of the shear strength.
