For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.
Not applicable – no normative references in this document.
3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 catch device device, which keeps or pulls a component in place, but does not require a second action in order to release it, e.g. a magnetic catch or a self-closing-mechanism 3.2 locking mechanism mechanism that limits access to the interior of a unit or a storage element. It requires a key or a combination in order to operate it or to make it possible to operate it. 4 General test conditions 4.1 Preliminary preparation The tests specified in this Standard are designed to be applied to an item of furniture that is fully assembled and ready for use. The tests refer to furniture parts with conventional functions. Combination of tests may be necessary to cover the properties of multi-function parts, e.g. a shelf that can be pulled out on runners shall be tested for strength of shelf supports as well as for strength as an extension element. Before any of the tests are commenced, the item shall be old enough to ensure that it has developed its full strength. SIST EN 14074:2004

Free standing units shall be placed on the floor surface (5.2) with stops (5.4) around each leg or base. The tests shall be carried out in indoor ambient conditions but, if during a test, the atmosphere temperature is outside the range 15 ºC to 25 ºC, the maximum and/or minimum temperature shall be recorded in the test report. Tighten any assembly fittings before testing. Further re-tightening shall not take place unless it is specifically required by the manufacturer. 4.2 Test equipment The forces in the static load tests shall be applied sufficiently slowly to ensure that the influence of dynamic load is negligible. Unless otherwise stated, the static loads shall be maintained for (10 ± 2)s. The forces in durability tests shall be applied sufficiently slowly to ensure that heating does not occur. Unless otherwise stated, the durability loads shall be maintained for (2 ± 1)s. Unless otherwise specified, the tests may be applied by any suitable device because results are dependent only upon correctly applied loads and not upon the apparatus. The test equipment shall be capable of following the deformations that may occur during the tests. 4.3 Tolerances Unless otherwise stated:  forces shall have an accuracy of ± 5% of the nominal force;  dimensions an accuracy of ± l,0 mm of the nominal dimension;  masses an accuracy of ± 0,5% of the nominal mass;  velocities an accuracy of ± 5% of the nominal velocity;  angles an accuracy of ± 2º of the nominal angle. The accuracy for the position of loading pads shall be ±
