24、it from unintentional folding when placed in themanufacturers recommended use position. Latching devicesfor folding steering handles on scooters shall be tested inaccordance with 6.9. During and upon completion of this test,the unit shall remain latched in its manufacturers recom-mended use position

25、.5.4 Curb Impact TestsUnits shall be tested per 6.1.5.5 Folding Mechanisms, Hinges, and ClearancesThisrequirement is intended to eliminate possible crushing,laceration, or pinching hazards that might occur in foldingmechanisms and hinges. Examples are the motion of a hingethat produces a scissor act

26、ion and the changing clearances atthe hinge line between two hinged portions, such that the gapwill admit fingers at one position of the hinge but not at allpositions. This requirement is also intended to eliminatepossible hazards that may be caused by changing clearances.The different pinch clearan

27、ce requirements listed reflect thedifferent modes of entrapment or pinching that may be encoun-tered.5.5.1 Hinge-Line ClearanceUnits having a gap or clear-ance along the hinge line between a stationary portion and amoveable portion that weighs more than 0.2 kg (12 lb) shall beso constructed that, if

28、 the accessible gap at the hinge line willadmit a 5-mm (316-in.) diameter rod, it will also admit a 13-mm(12-in.) diameter rod at all positions of the hinge.5.5.2 Hinge-line clearance (5.5.1) and accessible clearance(5.5.3) requirements shall not apply to drive trains, wheels, orbrake systems.5.5.3

29、Accessible Clearances for Moveable SegmentsThisrequirement concerns clearances between movable segmentsintended for children in which the potential for pinching orcrushing fingers or other appendages exists. If such accessibleclearances admit a 5-mm (316-in.) diameter rod, they shall alsoadmit a 13-

30、mm (12-in.) diameter rod to prevent the trapping offingers.5.5.4 Inaccessibility of MechanismsMechanisms shall nothave any accessible part of the mechanism present a pinch orlaceration hazard.5.6 FastenersFasteners used for wheel hubs, brake pivots,accelerator pivots, steering linkage pivots, axle a

32、holes each no larger than 32-mm2(0.05-in.2)area.5.8.3 All guards and shields for pulleys and sprockets shallbe secured permanently or attached to prevent their removalfrom the unit without tools. The fasteners for those guards andshields shall be reusable.5.8.4 The entry and exit points on and off o

33、f the sprockets orpulleys of drivetrains (chain and sprocket or belt and pulley)and open running chain and belt sections shall be covered ontop and outwardly to prevent inadvertent touching from anormal riding position. A section of the rear sprocket or pulleydrive may be exposed to facilitate the i

34、nspection and mainte-nance of the drivetrain. The inside and bottom may be exposed.The drivetrain is not exempt from the finger-probe standard,but the probe (Fig. 1) shall be applied at angles relative to thenormal riding position and not applied from rearward orunderneath positions. A specific driv

40、heends shall be covered by smooth finish caps.5.20 Accessible PointsUnits shall not have accessiblepotentially hazardous sharp points that may occur because ofthe following: configuration, assembly devices that are fas-tened poorly, poorly sheared sheet metal, burrs on screws, andsplintered wood. Un

41、its that are intended to be assembled by anadult and contain potentially hazardous sharp points in theunassembled state shall be so labeled.5.21 Accessible EdgesUnits shall not have accessible,potentially hazardous sharp edges. Units that are intended to beassembled by an adult and may contain unpro

Test

43、 Methods6.1 Curb Impact Test:6.1.1 Apply a weight to the center of the unit equivalent tothe manufacturers specified upper weight limit.6.1.2 Drive the scooter into a high vertical fixed curb that isat least the radius height of the wheel at 2 m/s (6.6 ft/s).6.1.3 Repeat 6.1.2 for a total of three t

44、imes.6.1.4 Following the impact tests, the unit shall be com-pletely functional.6.2 Dynamic Brake Test:6.2.1 A unit shall be tested with a rider of at least 68.1-kg(150-lb) weight and shall have a stopping distance of no greaterthan 4.57 m (15 ft) from an actual test speed of 16 km/h (10mph) or grea

45、ter as determined by the equivalent ground speedspecified in the following.6.2.2 The following test conditions shall be followed:6.2.2.1 The unit shall be ridden over a dry, clean, smoothpaved test course free from protruding aggregate. The testcourse shall provide a coefficient of friction of less

46、than 1.0 andshall have a slope of less than 1 %.6.2.2.2 The wind velocity shall be less than 11 km/h (7mph).6.2.2.3 The unit shall attain the specified ground speedwhile the rider is in the normal riding position.6.2.2.4 The rider shall remain in the normal riding positionthroughout the test.6.2.2.5

47、 The unit must be moving in a straight line at the startof the brake application.6.2.2.6 Corrections for velocity at the initiation of brakingmay be made. The corrected braking distance shall be com-puted as follows:Sc5 Vs/Vm!2Sm(1)where:Sc= corrected braking distance,Vs= specified test velocity,Vm=

48、 measured test velocity, andSm= measured braking distance.(1) The test run is invalid if at the commencement of thetest, the measured test speed of the unit is not less than norgreater than the test speed required by 1.5 km/h (0.9 mph).6.2.2.7 Four test runs are required. The stopping distanceshall

49、be determined by averaging the results of the four testruns.6.2.2.8 The stopping distances specified are based on a riderweight of at least 68.1 kg (150 lb) and a maximum rider andunit weight combination of 91 kg (200 lb). Greater stoppingdistances are allowable for heavier riders and test equipmentweights at the rate of 0.30 m per 4.5 kg (1.0 ft per 10 lb).6.2.2.9 A test run is invalid if wheel lockup occurs.6.3 Dynamic Strength Test:6.3.1 Apply a weight to the deck or seat of the unitequivalent to the manufacturers specified upper weight lim
