EXAMPLE: a certain component like a work surface. 3.3 TV-furniture A storage-type furniture product used or designed to support televisions, television monitors and similar objects. 3.4 bracket A rigid support device to prevent overturn. NOTE: it is usually made of metal, not a flexible device like a belt or a cable tie. 4 General Test Conditions 4.1 Pre-treatment Products to be tested shall be intactly assembled and deliverable finished products. The product and its components shall be assembled and / or configured in accordance with the instructions provided. Unless otherwise stated, the tests shall be performed in the configuration that is least conducive to the mechanical properties. If assembly or configuration instructions are not provided, then, the assembly or fitting-together method shall be recorded in the test report. Before the tests, fittings shall be tightened, and shall not be tightened again during the test when there are no special requirements in the manufacturer's instructions. If changes in product configuration are required to simulate the worst-case scenario, then, this shall be recorded in the test report. Unless otherwise specified by the manufacturer, before the tests, the unit shall be placed without load for at least 24 hours under indoor environmental conditions. The test shall be carried out on the test ground. The unit shall be leveled, and the leveling device shall be set in the middle position, but it shall not be more than 13 mm from the fully closed position. The units used for installation on buildings shall only be tested in accordance with 6.7. If the test cannot be carried out in accordance with the stipulations of this document, then, it shall be close to the stipulations. Any deviations from the test methods specified in this document shall be technically assessed and recorded in the test report. 4.2 Loading Force The speed of static load application shall be slow, so as to ensure that the additional dynamic load is small enough to be ignored. Unless otherwise specified, each load specified to be applied shall be maintained for 10 seconds ~ 15 seconds. When loading, the force value can be replaced by the mass of the weights. The conversion uses the relations 10 N = 1 kg. Appendix A provides guidelines for the selection of loads and force values, etc. for the tests. Appendix B specifies the loads and force values. Appendix C explains the principle for the selection of test methods included in this document. 4.3 Tolerances 5 Test Equipment and Facilities 5.1 Unless otherwise specified, any applicable test equipment can be used for tests, because the test results only depend on whether the applied force is correct and not on the test equipment itself. The test equipment shall not hinder the deformation of the units, that is, during the tests, the test equipment shall be able to move with the movement of the units, so as to ensure that the load is always in the specified position and direction. 5.2 Ground: a hard, level and flat surface. 5.3 Wall surface: it shall be hard, vertical and flat. 5.4 Stops: used to prevent the units from sliding but cannot restrict the units from overturn. The height of the stops shall be the lowest height that just prevents the units from moving. 5.5 Mass: the applied mass shall not enhance the unit structure, nor shall it change the stress distribution of the units. 5.6 Load of suspended filing pockets: paper or similar substitutes shall be used for loading. 5.7 Spherical objects: for example, glass beads with a diameter of 10 mm ~ 15 mm, which shall be loosely packed into a large flexible bag, so as to allow them to move in the bag during the tests. NOTE: loose means the bag is about 50% filled. 5.8 Loading pad: a rigid disc with a diameter of 100 mm and an edge rounding radius of 12 mm. The loading surface is a flat surface. If the space is limited, a loading pad with a diameter of 50 mm can be used. 5.9 TV formworks: two frames or boxes with the shape shown in Figure 1 and the dimensions shown in Table 2, which are capable of supporting loads acting through their center of gravity. The unloaded mass shall be (10  0.2) kg. The center of gravity of the unloaded formworks shall be the geometric center of the unloaded formworks. The change in the position of the center of gravity of the loaded formwork and the position of the center of gravity of the unloaded formwork shall be limited to within 5 mm. During the tests, the formworks shall be kept in the initial position. Apply the vertical downward force specified in Table B.1 to the front panel of the opened extension element or the centerline position 50 mm away from the outer edge of the opened opening door or flap. For TV-furniture with both extension elements and opening doors, force shall be successively applied to each component. In accordance with the stipulations of Table B.1, assemble additional loads on the unloaded TV formworks and repeat the above-mentioned test procedures. Record whether the TV-furniture overturns or is supported by opened extension elements, opened doors or opened flaps, and whether the TV formworks overturn. During the test, if the TV-furniture is prevented from overturn due to opened extension elements, opened opening doors or opened flaps, then, these components shall be closed, and the test shall be re-performed. 6.8.4 Stability of TV-furniture with doors and / or extension elements closed---with storage components unloaded All storage components shall be unloaded. All doors and extension elements shall be fully closed. Place the unloaded TV formworks at the straight center 150 mm from the front edge of the TV- furniture (see Figure 12). Apply the horizontal outward-tilting moment at the point most likely to cause the units to overturn. In accordance with the stipulations of Table B.1, assemble additional loads on the unloaded TV formworks, and repeat the above-mentioned test procedures. Record whether the TV formworks overturn. 7 Test Report The test report shall at least include the following content: a) Serial No. of this document; b) Laboratory name and address; c) Test location (if different from laboratory address); d) Unique identification of the test report, including the identification on each page and the identification at the end of the test report; e) Consignor’s name and address; f) Description and confirmation of units, such as: product type, “name” and photos, etc.; g) The state of the units when received, such as: pending installation, installed and defective, etc.; Appendix A (informative) Guidelines for the Selection of Loads and Forces for Stability Test of Storage Units A.1 Principle This Appendix aims at providing guidance to those who wish to specify the stability requirements for storage units. Appendix B provides recommended loads and forces applicable to the stability test of household and non-household cabinets.
