26、 sample for testing shall be stored in indoor ambient conditions for at least one week immediately prior to testing any variations from this procedure shall be justified in the report. Before testing, any fabrics used shall be cleaned or washed and dried twice following the manufacturers instruction

27、s. The test shall be carried out in indoor ambient conditions, but if during a test the atmosphere temperature is outside the range 15 C or above 25 C, the maximum and/or minimum temperature shall be recorded in the test report. The changing unit shall be tested as delivered. If of knock-down type,

28、it shall be assembled according to the instructions supplied with the unit. If the changing unit can be assembled or combined in different ways, the most onerous combinations shall be used for each test. All fittings shall be tightened in accordance with the manufacturers instructions and shall not

29、be retightened throughout the test procedure. 3.2 Application of forces The forces in the static load tests shall be applied sufficiently slowly to ensure that negligible dynamic force is applied. The forces in the durability tests shall be applied at a rate to ensure that excessive heating does not

30、 occur. 3.3 Tolerances Unless otherwise stated, the following tolerances apply: Forces: 5 % of the nominal force; Masses: 0,5 % of the nominal mass; BS EN 12221-2:2008+A1:2013 EN 12221-2:2008+A1:2013 (E)6 Dimensions: 1,0 mm of the nominal dimension; Angles: 2 of the nominal angle; Positioning of loa

31、ding pads: 5 mm; Duration of forces: ( 2 1) s for durability tests and (10 2) s for static load tests The tests are described in terms of the application of forces. Masses can however be used. The relationship 10 N = 1 kg may be used for this purpose. 3.4 Test sequence The tests shall be carried out

32、 in the order laid down in this standard and on the same changing unit. 4 Test equipment 4.1 General Unless otherwise specified, test forces may be applied by any suitable device, which does not adversely affect the results. 4.2 Measuring cones Cones made of plastics or other hard, smooth material w

47、 Assembly and inspection before test Assemble the changing unit in accordance with the manufacturers instructions. Where changing pads or the like provide the barriers for the changing unit they shall be assembled for use. Prior to the test, inspect the changing unit visually and record any defects.

48、 Tighten all fittings. 5.2 Measurement of changing area 5.2.1 Measurement of width Position the changing unit on the base (see 4.5, 4.6, 4.7) according to the type. Place the test beam (see 4.11) across the width of the changing area (as shown in Figure 7). Place a measurement rod (see 4.12 ) throug

49、h the central hole of the test beam (see 4.11) so that it rests on the top of the changing surface. h is the distance that the measuring rod protrudes below the underside of the test beam. Place two measuring rods, adjusted to extend one third of h below the underside of the test beam, through the relevant holes in the test beam. If the collars on these two measuring rods rest on the upper surface of the test beam then the width requirement is met. Key 1 Minimum width Figure 7 Method of measurement of th
