It supersedes BS 7423:1999 and BS EN 716-2:1996, which are withdrawn. BSI, as a member of CEN
3、, is obliged to publish EN 716-2 as a British Standard. However, attention is drawn to the fact that during the development of this European Standard, the UK committee voted against its approval as a European Standard. The reason for this disapproval was that, in the opinion of the UK Committee, BS
4、EN 716-2 does not address the safety issues related to the interaction of other products that might be supplied and intended to be attached to cots. In these instances, an additional risk assessment should be undertaken. The UK participation in its preparation was entrusted to Technical Committee CW
5、/41, Child use and care articles. A list of organizations represented on this committee can be obtained on request to its secretary. This publication does not purport to include all the necessary provisions of a contract. Users are responsible for its correct application. Compliance with a British S

27、thods for assessing the safety of childrens cots and folding cots for domestic use. It applies to children s cots and folding cots with an internal length greater than 900 mm but not more than 1 400 mm. 2 Normative references The following referenced documents are indispensable for the application o
28、f this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

30、e. The test unit shall be stored in indoor ambient conditions for at least one week immediately prior to testing. Any deviation from this procedure shall be stated in the test report. Before testing, any fabrics intended to be removable shall be cleaned or washed twice in accordance with the manufac
31、turers instructions. If no instructions are supplied, the manner of washing/cleaning shall be stated in the test report. The tests shall be carried out under indoor ambient conditions, but if during a test the atmospheric temperature is outside the range 15 C to 25 C, the maximum and/or minimum temp
32、erature shall be recorded in the test report. The cot shall be tested as delivered. If the cot is a knock down type, it shall be assembled according to the manufacturers instructions supplied with the cot. If the cot can be assembled, combined or adjusted in different ways, the most adverse combinat
33、ion shall be used for each test. Knock-down fittings shall be tightened before testing. Further re-tightening shall not take place unless this is specifically required by the manufacturer. In the case of designs not catered for in the test procedures, the tests shall be carried out as far as possibl
34、e as described, and a list made of the deviations from the test procedures. 3.2 Test equipment Unless otherwise specified, the tests may be applied by any suitable device because results are dependent only upon correctly applied forces and loads and not upon the apparatus.

EN 716-2:2008 (E) 6 The equipment shall not inhibit the deformation of the cot during testing. It shall be able to move so that it can follow the deformation of the cot during testing, s
36、o that the loads are always applied at the specified point and in the specified direction. All loading pads shall be capable of pivoting in relation to the direction of the applied force. The pivot point shall be as close as practically possible to the load surface. 3.3 Application of forces The for
37、ces in the static load tests shall be applied sufficiently slowly enough to ensure that negligible dynamic force is applied. The forces in durability tests shall be applied at a rate to ensure that excessive heating does not occur. 3.4 Tolerances Unless otherwise stated, the following tolerances app
38、ly: Forces: 5 % of the nominal force; Masses: 0,5 % of the nominal mass; Dimensions: 1,0 mm of the nominal dimension; Angles: 2 of the nominal angle; Positioning of loading pads: 5 mm; Duration of forces: ( 2 1) s for durability tests (10 2) s for static load tests, including tension, torque and bit
39、e tests. The tests are described in terms of the application of forces. Masses can, however, be used. The relationship 10 N = 1 kg shall be used for this purpose. 3.5 Test sequence The tests shall be carried out in the order laid down in this standard and on the same cot. 3.6 Prevention of movement
40、during test If the cot tends to slide or roll during the tests specified in clause 5, it shall be restrained by stops (4.6). 4 Test apparatus 4.1 Measuring probes Probes made of plastics or other hard, smooth material mounted on a force-measuring device. There shall be one probe with a diameter of 7
41、 mm (-0,1/+0 mm), see Figure 1a. There shall be five probes with an angle of 30 0,5 with diameters of 25 mm (0/+0,1 mm), 45 mm (0/+0,1 mm), 60 mm (0/+0,1 mm), 65 mm (0/+0,1 mm) and 85 mm (0/+0,1 mm) with conical ends, see Figure 1b.
