4 General test condition 4.1 Preliminary preparation The wall attachment device(s) shall be mounted according to the instructions supplied with them. The most adverse configuration shall be used and the mounting or assembly method shall be recorded in the test report.If mounting or assembly instructions are not supplied, the most adverse configuration shall be used and the mounting or assembly method shall be recorded in the test report. The fixing to the wall shall be of such strength that the test result is not influenced. Fittings shall be tightened before testing and shall not be re-tightened unless specifically required in the manufacturer’s instructions, lithe configuration is to be changed to produce the worst-case conditions, this shall be recorded in the test report. For testing a range of related wall attachment devices, only worst case(s) need to be tested. The tests shall be carried out in indoor ambient conditions at a temperature between 15 °C and 25 °C. If during a test the temperature is outside of the range of 15°C to 25°C, the maximum and/or minimum temperature shall be recorded in the test report.Wall attachment devices which include structural hardware parts made of hygroscopic plastic materials, e.g. polyamide shall be conditioned at (23 ± 5) °C and a relative humidity of (50 ± 5) % for at least seven days before testing. Particle boards used for the test setting shall be kept in the standard climate for at least 7 days before testing. Before beginning the testing, visually inspect the wall hanging device(s) thoroughly. Record any defects so that they are not assumed to have been caused by the tests. Carry out measurements when specified. 4.2 Test equipment 4.2.1 Test wall A rigid, vertical and flat surface. 4.2.2 Particle board properties The properties of the particle board shall be as specified in Table 1. The thicknesses shall be as specified in Clause 5 and the thickness tolerance shall be土0,3 mm.BS EN 15939 pdf download.
