mass in kg. as specified by the manufacturer, for which one wall attachment device / one set of wall attachment devices will fulfil the strength requirements specified in this standard
Note 1 to entry: A test method for the determination of the loading capacity is described in Annex B (informative).
3.2
wall attachment device
device including the component that is attached to the cabinet and the component that is attached to the wall
Note 1 to entry: A component that is attached to the cabinet is e.g. a suspension bracket.
Note 2 to entry: A component that is attached to the wall is e.g. a hook, a rail.
Note 3 to entry: A set of wall attachment devices consisting of more than one component (e.g. an upper and
lower part).
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. If the 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.
For testing, that test frame has to be selected, that is closest to the cabinet dimensions for which the wall attachment device is intended.
The test frame is made of steel. For all tests in test frame A. the test cabinet Ti (see Figure 4) is mounted. In test frame B and test frame C, the test cabinet T2 (see Figure 7) is mounted.
The test frame shall be made as follows:
a) the steel frame shall be made of square, hollow components (30mm x 30mm x 1,5 mm) according to EN 10305-5 (see Figure 2);
b) the pivoting arm. 600 mm in length, shall be a square, hollow component (30 mm x 30 mm x 1.5 mm) according to EN 10305-5 (see Figure 2);
c) the loading panel shall be made out of particle board (see 4.2.2). The dimensions for BI shall be 600 mm x 300 mm (Figure 6) and for B2 1000 mm x 600 mm (Figure 9). The thickness of the loading panel shall be suffIcient to bear the load, but at least 19 mm. For test frame C the loading panel is mounted on the top of the test frame.
d) the side panels of test cabinets Ti and T2 shall be manufactured according to Figure 5 b) or Figure 8 b) out of particle board (see 4.2.2) with a thickness of 16 mm. They shall be with a groove for the back panel;
e) the top panels of test cabinets Ti and T2 shall be manufactured according to Figure 5 a) or Figure 8 a) out of particle board (see 4.2.2) with a thickness of 16 mm;
f) the back panel of test cabinets TI and T2 shall be made out of flbreboard (see 4.2.3) with the dimensions 250mm x 517 mm x 3.2 mm for TI and 200 mm 917 mm x 3,2 mm forT2.
The steel frame shall be welded together all around all cross sections.
The top panel of test cabinets TI and T2 (see Figure 5 a) or Figure 8 a)) shall be jointed to the side panels using wooden dowels (4.2.5) without the use of glue.
The side panels of test cabinets TI and T2 (see Figure 5 b) or Figure 8 b)) shall be fixed to the steel frame in a manner so that the displacement of the side panels in relation to the steel frame under the applied load is no more than 1 mm. The side panels shall be fixed to the steel frame at least 100 mm from the top of the side panel.
The loading panel shall be fixed to the steel frame (see Figure 10, Figure 11 or Figure 12) in a manner so that the horizontal displacement of the loading panel in relation to the steel frame under the applied load is no more than 1 mm.BS/EN 15939-2019 pdf download.
