Figure 20 — Small parts cylinder 5.7 Bite tester The bite tester, see Figure 21, consists of two sets of teeth, see Figure 22, made from H13 high chrome tool steel or equivalent and hardened to 45-50 Rockwell C. There are two teeth at the top and two at the bottom of the bite tester, positioned so that the vertical centre line of one pair of teeth is (1 ± 0,1) mm in front of the centre line of the other set of teeth. In the fully closed position, the teeth shall overlap each other by (1 ± 0,1) mm. The outer most corners of the teeth shall have a radius of (0,3 ± 0,1) mm. The teeth shall be mounted so as to pivot about a point (50 ± 1) mm from the rear most pair of teeth and positioned so that when closed the centre lines of the two pairs of teeth are parallel to each other. The bite tester shall be equipped with a stop to prevent the distance between the teeth from exceeding (28 ± 1) mm when fully opened. The closing force of the teeth shall be set at (50 ± 5) N.
The bite tester shall be provided with a guide to prevent items entering further into the fully opened jaws by more than (17 ± 1) mm. The bite tester shall be equipped with a means whereby a force of (50 ± 5) N may be applied along its centre line in a direction tending to pull the teeth off the sample. SIST EN 1888:2012

The test apparatus shall allow the articulating arms to be adjustable in height and across the width of the irregular surface test equipment to accommodate different types and sizes of vehicle. The articulating arms shall pivot around their fixing point. When in the horizontal position, each arm shall exert a vertical force on the handles of (20 ± 1) N. SIST EN 1888:2012

Where a surface is coated with a multi-layer of paint or similar coating, the test sample shall not include the base material. 7 Thermal hazards (see A.3) Fabrics shall not produce a surface flash when applying a flame as described in EN 1103.

d) any "car seat" suitable from birth conforming to ECE 44. 8.1.1.1.2 Vehicles intended for use from 6 months of age Car seats which comply with ECE 44 are exempt from this requirement. Vehicles intended for children from 6 months of age shall have a restraint system complying with the relevant requirements of 8.1.3. Seat units intended to be used from 6 months of age shall be marked with the warning in 10.2.5. The warning shall be visible during folding, unfolding or adjustment of the vehicle. 8.1.1.1.3 Seat units Car seats which comply with ECE 44 are exempt from these requirements. When measured in accordance with 8.1.1.2.1:  the angle (1) between the seat and the backrest (see Figure 26) shall not be less than 95°; and  the angle (2) between the seat and the horizontal (see Figure 26) shall not be less than 0°; and
 the angle (3) between the backrest and the horizontal (see Figure 26) shall not be less than 0°. NOTE Angles below the horizontal line are considered to be less than 0°. The length of the backrest shall not be less than 380 mm. When tested in accordance with 8.1.1.2.1 the top of the backrest of the seat unit shall be equal to or higher than the top of part 2 of the angle measuring device.

Any removable head cushion shall be removed before performing the measurements NOTE Any component that may impair the correct positioning of part 1 of the angle measuring device (crotchstrap, padded parts, buckle etc.) should be positioned such as to ensure part 1 of the device is correctly placed onto the seat. Place the angle measuring device (see 5.3) on the seat unit with part 1 against the seat and with part 2 (Figure 18) against the backrest as shown in Figure 26. Raise the whole device for at least 50 mm from the seat with part 2 (Figure 18) maintaining complete contact with the backrest. With the device in this position fold up part 1 to its maximum reach. Then lower the whole device as far as possible by its own weight, with part 2 (Figure 18) maintaining complete contact with the backrest. Then slowly unfold part 1 (Figure 18
