23、This document (EN 716-2:2017) has been prepared by Technical Committee CEN/TC 207 “Furniture”, the secretariat of which is held by UNI. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by December 201

24、7, and conflicting national standards shall be withdrawn at the latest by December 2017. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent right

25、s. This document supersedes EN 716-2:2008+A1:2013. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association. Compared to EN 716-2:2008+A1:2013, the following modifications have been made: introduction of the elements of the amend

26、ment; modification of the wrong references to clauses; clarification of 4.3, “Test mattress”; modification of 5.7.1, “Folding test of the mattress base and cot base”. EN 716, Furniture Childrens cots and folding cots for domestic use, is composed with the following parts: Part 1: Safety requirements

27、; Part 2: Test methods. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic o

28、f Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom. BS EN 7162:2017EN 716-2:2017 (E) 5 1 Scope This Europea

29、n Standard specifies test methods for assessing the safety of childrens cots and folding 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 documents, in whole or in part, a

30、re normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN ISO 2439:2008, Flexible cellular polymeric material

31、s Determination of hardness (indentation technique) (ISO 2439:2008) ISO 7619-2, Rubber, 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

32、 assembled and ready for use. 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

33、accordance with the manufacturers 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

34、maximum and/or minimum temperature 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

35、, the most adverse combination 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 ca

36、rried out as far as possible 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.

37、 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, so that the loads are always applied at the specified point and in the specified direction. All loading pads shall be capable of pivot

38、ing in relation to the direction of the applied force. The pivot point shall be as close as practically possible to the load surface. BS EN 7162:2017EN 716-2:2017 (E) 6 3.3 Application of forces The forces in the static load tests shall be applied sufficiently slowly enough to ensure that negligible

39、 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 apply: Forces: 5 % of the nominal force; Masses: 0,5 % of the nominal mass; Dimensions: 1,0 mm of the

40、 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 bite tests. The tests are described in terms of the application of forces. Masses can, however, be use

41、d. 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 during test If the cot tends to slide or roll during the tests specified in Clause 5, it shall be r

42、estrained 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 mm (0,1/+0 mm), see Figure 1 a). There shall be five probes with an angle of 30 0,5 with diameters

43、 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 1 b). 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 F
