16、d by the muscular activity of a user with a body mass of more than 35 kg and less than 100 kg. It specifies safety requirements, test methods, marking and information supplied by the manufacturer to reduce the risk of injuries to both third parties and the user during normal use. Kick scooters for u

17、se by users of less than 35 kg do not belong to the scope of this document. They are toys. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated refer- ences, only the edition cited applies.

Rigid and protruding parts that may cause entrapment or injuries shall be protected. This protection shall not come loose during tests perfo

23、rmed in Clause 5. EN 14619:2004 (E) 6 4.2.2 Parts moving against each other 4.2.2.1 General The requirements specified in 4.2.2.2 to 4.2.2.5 have to be tested according to 5.8. 4.2.2.2 Distance between the parts The distance between accessible moveable parts shall be either smaller than 5 mm or wide

24、r than 18 mm in any position. This requirement does not apply to the wheels/wheel support system or the braking/rear brake system, if provided. 4.2.2.3 Folding mechanism Any folding mechanism shall be designed to fix the kick scooter for use in a simple, rigid and safe way. It shall resist all tests

25、 without damage. Fixing components should not have contact with front wheel in any position. An inadvertent unlocking of the mechanism shall be impossible. If the distance as specified in 4.2.2.2 is not met other designs to protect the user from unintentional injuries shall be provided. 4.2.2.4 Slid

26、ing mechanism Sliding mechanisms shall be protected against unintentional opening or collapse. 4.2.2.5 Springs Springs shall not be accessible if the gap between two consecutive spirals or turns allow a 5 mm diameter rod to be insert on a 10 mm depth. 4.2.3 Steering system The steering system shall

27、be constructed: a) to avoid contact between wheels and other parts of the kick scooter; b) that the length adjustment fixing avoid unintentional opening; c) that the steering column, if it is sliding, shall be adjusted for height, and have a permanent mark that indi- cates the minimum insertion dept

28、h of the column; this mark shall be positioned at a distance equivalent to and not less than two and a half times the diameter of the column and shall not affect its strength; d) that the end of the handlebar is equipped with hand grips or plugs, which withstand a tensile load of at least 70 N. When

29、 tested according to Clause 5 there shall be no break or functional damage of the steering system. 4.2.4 Deck The deck shall resist all tests specified in Clause 5 without any functional damage. It shall be equipped with an anti-slide surface with an area of at least 200 cm 2 . EN 14619:2004 (E) 7 4

30、.2.5 Bearings The bearings shall be designed in such a way as to be functional after performing all the tests according to Clause 5. They shall be constructed in such a way as to permit servicing according to the information supplied by the manufacturer without impairment of their operational safety

31、. 4.2.6 Axles The axles shall be attached and designed in such a way as to ensure that they cannot become loose, dis- placed or deformed during use. The wheels shall be secured on the axles against unintentional loosening. These requirements are considered to be fulfilled if the axles are not loosen

32、ed, deformed or displaced to such an extent as to impair proper functioning, and the wheels have not become loose after the tests according to Clause 5. 4.2.7 Wheels The wheels shall be constructed from non-slip material. This requirement is considered to be fulfilled if a coef- ficient of adhesion

33、0of at least 0,30 is achieved in the test according to 5.3. After the tests according to Clause 5, the wheels shall not show tearing. They shall further not have loosened or be deformed to the extent that a risk of their becoming locked exists. If a rear wheel and its axle differ from those at the f

34、ront they shall be tested according to 5.7. 4.2.8 Self-locking fixings Where self-locking nuts are used, the entire thread, including the locking section, shall be in contact with the bolt. Self-locking nuts and other self-locking fixings that are loosened several times for the purpose of modifi- ca

35、tion or servicing, shall be suitable for this purpose. The information supplied by the manufacturer shall indi- cate, when self-locking nuts and other self-locking elements can lose their effectiveness. 4.2.9 Mechanism to reduce the speed If a kick scooter is equipped with a mechanism to reduce the

36、speed this mechanism shall continue to make contact with the surface to which it is intended and no fastening devices shall have loosened when tested according to Clause 5. The mechanism shall effectively and smoothly reduce the speed without coming to an abrupt stop. 4.2.10 Strength All functional

37、parts after testing according to Clause 5 shall not collapse or fail to comply with the relevant re- quirements specified in this document. 5 Test methods 5.1 General The kick scooter to be tested shall be assembled and adjusted according to the information supplied by the manufacturer. Two test spe

38、cimen (two kick scooters) of the same type shall be tested according to the order described in 5.2. EN 14619:2004 (E) 8 5.2 Order of tests 5.2.1 Specimen A The specimen shall be subjected to the test in the following order: a) test of external finish (see 5.8); b) wheel adhesion test (see 5.3); c) e

39、ndurance test (see 5.7). 5.2.2 Specimen B The specimen shall be subjected to the test in the following order: a) static load test of the deck (see 5.4.1); b) static load test of the steering column (see 5.4.2); c) drop test (see 5.5); d) impact test against front wheel (see 5.6). 5.3 Wheel adhesion

40、test The wheel adhesion shall be tested by pulling a wheel along a steel plate with a fine brushed and degreased surface of arithmetical mean roughness R aof 1,5 to 2,0 m (see Figure 2). A vertical force F 1of 100 N shall be applied to the wheel which is moved along the steel plate perpendicular to

41、the kick scooters longitudinal axis and perpendicular to the surface brush direction by a horizontal force F 2 , applied at the height of the wheels axis. The maximum force shall be recorded. The test shall be repeated ten times and the mean value of F 2shall be calculated. The test shall be carried

42、 out at a speed of 1 mm/s. The coefficient of adhesion shall be calculated according to equation (1): 1 2 0 F g m F E + = (1) where: 0is the coefficient of adhesion; F 1is the load applied to wheel, in Newton; F 2is the adhesive force, in Newton; m Eis the mass of the wheel, in kilograms; g is the s

43、tandard acceleration due to gravity (g = 9,81 m/s 2 ). EN 14619:2004 (E) 9 Figure 2 Adhesion of wheels 5.4 Static load test 5.4.1 Deck A test load of 200 kg with a surface of 100 mm 100 mm shall be applied on the centre of the deck. 5.4.2 Steering column The steering column shall be extended to the

44、maximum and centrally loaded with a 50 kg mass applied in directions A and B, each for 5 min, as shown in Figures 3 and 4. Key 1 Example of a fixation of the front wheel m = 50 kg Figure 3 Static load test in direction A EN 14619:2004 (E) 10 Key 1 Example of a fixation of the rear wheel m = 50 kg Fi

45、gure 4 Static load test in direction B 5.5 Drop test A cylindrical mass is dropped on the centre of the deck. The test apparatus shall consist of a) cylindrical mass of 20 kg and a diameter of 100 mm; b) sheet of rubber, fitted to the mass, with 17 mm thickness and 70 shore A; c) guide tube. Drop th

46、e cylindrical mass, in free fall, down the guide tube on to the centre of the deck of the kick scooter three times. During the test hold the scooter to prevent it from rolling away. Drop the mass through 300 mm on the centre of the deck. If plastic material is used for deck or steering system, the k

47、ick scooter has to be conditioned for at least 6 h at a temperature of ( 5 1) C. Start the test within 1 min of removing the kick scooter from the conditioning environment and complete it within 5 min. 5.6 Impact against front wheel A kick scooter shall be impacted in the forward direction onto the

48、front wheel with an energy of 135 J and an impact velocity v 1of (4,5 0,5) m/s. The type of suspension shall ensure that this energy is absorbed by the front wheel. EN 14619:2004 (E) 11 5.7 Endurance test A complete kick scooter shall withstand the endurance test. This test is carried out on a test apparatus as shown in Figure 5 and at a circumferential speed of 0,5 m/s for a distance of 12 km. A mass of 90 kg shall be placed centrally on the deck. 10 kg shall be placed out of the handlebar or joy stick. The distance between the raised section
