The other properties of the impact steel plates are shown in Table 2. 5.11 Obstacles for the caster durability test. two steel bars with a width of 50 mm and a height of 2 mm; the radius of the edge of the steel bars is 2 mm, and the spacing is 500 mm. They are laid flat on the ground, perpendicular to the test direction.6 Test Steps of Non-moving Components6.1 Shelf Test 6.1.1 Overview For units with an uncertain number of shelves, unless otherwise specified, the number of shelves is determined through this method. divide the internal height (unit. mm) of the unit by 200 and subtract 1 from the nearest integer. 6.1.3 Shelf positioning test - vertical downward force This test is only applicable to non-fixed shelves. 6.1.5 Strength test of shelf supports Except for the position 220 mm close to one end of the support, other positions of the shelf shall be evenly loaded in accordance with half the load specified in the shelf bending test (6.1.4). Let the impact steel plate (see 5.10) overturn 10 times against the support (see Figure 3). The impact surface of the impact steel plate shall be covered with rubber. All supports of the shelf shall be tested. 6.2 Test of Top Panels and Bottom Panels 6.2.1 Continuous loading test of top panels and bottom panels This test is applicable to all top panels, as well as bottom panels that are not fully supported by the ground during use. 6.3 Test of Clothes Hanging Rod and Supports 6.3.1 Strength test of clothes hanging rod supports Clothes hanging rods that are structurally connected to each other shall each be loaded. The span of a clothes hanging rod is the distance between consecutive supports. Install the clothes hanging rod on the support of the unit. Use the load specified in Table 1 to load all components used for storage. Each support shall be continuously loaded. The end supports are loaded in accordance with the load specified in Table B.1, and the loading point shall be close to the supports. The intermediate support is loaded at twice the load specified in Table B.1, and the loading point shall be close to the supports (see Figure 5). 6.4 Structural Strength Test 6.4.1 Strength test of structures, chassis and / or legs This test does not apply to units attached to walls, ceilings, floors or other furniture products.
