30、turer or the material standard. 6 Storage of test samples after bonding After curing the sample made with elevated temperature curing adhesives shall be exposed and/or after a storage period of 16 h under the conditions as given below (unless otherwise specified by the adhesive manufacturer). The sa
31、mple for room temperature curing adhesives not exposed and/or tested immediately after curing shall also be stored as given below (unless otherwise specified by the adhesive manufacturer). Storage conditions: room temperature: (23 2) C relative humidity: (50 5 ) % 7 Cutting and preparation of test p
32、ieces The test sample shall be carefully cut into pieces with a suitable tool such as a band saw. The setting and spacing of the teeth and the operational speed shall be such that the frictional heating of the bond will be kept to a minimum. The cutting shall be straight and parallel. For cutting sh
33、all be straight and parallel. For cutting corrosion resisting steel and titanium alloy test samples a suitable cutting fluid may be used.

34、mperatures stated in the relevant material standard. When the test temperature is different from the ambient temperature then the rate of the heating shall be between 6 C to 10 C per minute. The rate of cooling need not be controlled. The application of load for all tests at temperature other than a
35、mbient shall be made immediately after the specimen has been held at the specified test range for 10 min unless a longer term of exposure is required. 8.2 For all test temperature excluding room temperature (23 2) C, temperature control of the test pieces shall be carried out with the aid of a therm
36、ocouple to ensure the accuracy of testing temperature and reproducibility of data. The junction of the thermocouple shall be firmly attached to the test piece in immediate contact with the metal in the position shown in Figure 2 and shielded from the heat source. 8.3 The number of test pieces for ea
37、ch determination shall be as required by the material standard. 8.4 Each test piece shall be identified in order to establish the panel from which it was cut. 9 Method of test 9.1 Tensile testing machine 9.1.1 An approved tensile testing machine shall be used. The failing load of the test piece shal
38、l be within 10 % to 90 % of the upper limit of the selected loading range of the machine. 9.1.2 The test loads shall be recorded within an accuracy of 1 %. 9.2 Method of fixing The ends of the specimen shall be gripped tightly with a good fit in the jaws of the testing machine. The jaws and the test
39、 pieces shall be aligned such that the jaws are directly opposite each other and in such a position that an imaginary straight line will pass through the centre of the bonded area and through the point of fixing. The specimen shall be gripped (50 5) mm from each edge of the lap joint (see also Figur
40、e 3). 9.3 Speed rate of loading The rate of loading shall be 2 800 N/min to 5 000 N/min. 10 Calculation of results The test results to be reported shall be calculated as follows: WLFR= EN 2243-1:2005Licensed Copy: Wang Bin, na, Fri Apr 14 02:34:58 BST 2006, Uncontrolled Copy, (c) BSI7 where R shear
