31、ith the requirements in Part 1. The tests are designed to evaluate properties without regard to materials, design/construction or manufacturing processes.

39、krest (see Figure 1) Note 1 to entry: The method for determining the junction line can be found in 4.2.“ 4 General test conditions 4.1 Preliminary preparation !The tests are designed to be applied to a high chair that is fully assembled according to manufacturers instructions and ready for use. If t
40、he product can be converted to other products not falling within the scope on this standard (e.g. table and small chair, adult chair, swings, booster seats, etc.), these configurations shall not be tested according to this standard. The tests shall be carried out in indoor ambient condition with a t
41、emperature between 15 C and 25 C. If the temperature lies outside this range, its maximum and minimum shall be recorded in the test report. The high chair shall be tested as delivered. If the high chair is a knock-down type, it shall be assembled according to the instructions supplied with it. If th
42、e instructions allow for different adjustments or configurations of components (e.g. inclination of the backrest, height of the seat, position of the tray, position of castors/wheels, etc.), the most onerous combination shall be used for each test. Knock-down fittings shall be tightened before testi
43、ng. Further re-tightening shall not take place unless this is specifically required by the manufacturers instructions.“ ! 4.2 Determination of the junction line The junction line is shown in Figure 1 below. Where the backrest and the seat do not meet, the junction line is the projection of the backr
44、est onto the seat (see Figure 1).

45、2. The junction line may vary when the backrest is adjusted in different positions.

46、 carried out on one sample and in the order laid down in this part of EN 14988 except for the test in 6.9, which shall be performed at the end of the whole test procedure.“ 4.4 Tolerances Unless otherwise stated, the following tolerances apply: Forces: 5%; BS EN 14988-2:2006+A1:2012EN 14988-2:2006+A

The relationship of 10 N = 1 Kg shall be used. 5 Test equipment 5.1 General Unless otherwise specified, test forces may be applied by any suita
48、ble device because results are dependent only upon correctly applied forces and not upon the apparatus. The test forces in the static load tests shall be applied sufficiently slowly to ensure that negligible dynamic forces are applied. 5.2 Test dummy A rigid cylinder 200 mm in diameter and 300 mm in height, having a mass of 15 kg and with its centre of gravity 150 mm above its base. All the edges of the cylinder shall have a radius of 5 mm. Two safety harness anchorage points shall be provided. These shall be positioned 150 mm from the base and 180 to eac
