DIN EN 716-2:2008-06 EN 716-2:2008 (E) 5 1 Scope This part of EN 716 specifies test methods for assessing the safety of childrens cots and folding
20、 cots for domestic use. It applies to childrens 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 of this document. For dated references, only the edition cited
21、 applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN ISO 2439:2000, Flexible cellular polymeric materials - Determination of hardness (indentation technique) (ISO 2439:1997, including Technical Corrigendum 1:1998) ISO 7619-2, Rubber,
22、vulcanized or thermoplastic Determination of indentation hardness Part 2: IRHD pocket meter method 3 General test conditions 3.1 Preliminary preparation The tests are designed to be applied to a cot that is fully assembled and ready for use. The test unit shall be stored in indoor ambient conditions
23、 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 manufacturers instructions. If no instructions are supplied, the man
24、ner 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 temperature shall be recorded in the test report. The cot shall b
25、e 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 combination shall be used for each test. Knock-down fittings shall be
26、 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 possible as described, and a list made of the deviations from the te
27、st 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. DIN EN 716-2:2008-06 EN 716-2:2008 (E) 6 The equipment shall not inhibit the deformatio
28、n of the cot during testing. It shall be able to move so that it can follow the deformation of the cot during testing, so 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
29、 force. The pivot point shall be as close as practically possible to the load surface. 3.3 Application of forces The forces 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 ra
30、te to ensure that excessive heating does not occur. 3.4 Tolerances Unless otherwise stated, the following tolerances apply: 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
31、 mm; Duration of forces: ( 2 1) s for durability tests (10 2) s for static load tests, including tension, torque and bite 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
32、 The tests shall be carried out in the order laid down in this standard and on the same cot. 3.6 Prevention of movement 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 pl
33、astics or other hard, smooth material mounted on a force-measuring device. There shall be one probe with a diameter of 7 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
34、 85 mm (0/+0,1 mm) with conical ends, see Figure 1b. DIN EN 716-2:2008-06 EN 716-2:2008 (E) 7 There shall be four cylindrical probes with diameters of 5 mm (-0,1/+0 mm), 7 mm (-0,1/+0 mm), 12 mm (0/+0,1 mm) and 18 mm (0/+0,1 mm) with hemispherical ends, see Figure 1c.

The test mattress shall have a cotton cover with a mass per unit area of 100 g/m2 to 120 g/m2. 4.4 Side impactor A pendul
38、um with a cylindrical head made of steel (Figure 3). The head of the pendulum shall be surrounded by a 10 mm thick layer of rubber of hardness 76 IRHD to 78 IRHD in accordance with ISO 7619-2.
