General Requirements4.1 Before testing, the units shall be completely assembled,unless otherwise noted, in accordance with the manufacturersinstructions.4.2 The unit or segment to b
15、e tested shall be in a room withan ambient temperature of 23 6 5C (73 6 9F) for at least 1h before testing.4.3 All testing required by this consumer safety specifica-tion shall be conducted on the same unit unless otherwisespecified.4.4 All components tested under Section 6 shall not showany evidenc
16、e of permanent deformation, material separation,visible cracking, or component failure that presents a hazard tothe user.4.5 The unit shall conform to 16 CFR 1303 and the FederalHazardous Substance Act (FHSA) both before and after alltesting.4.6 All exposed parts shall be smooth and free of splinter
17、s,spurs, burrs, and sharp edges.4.7 Units shall meet the specific requirements of Section 5.5. Specific Requirements5.1 BrakesUnits shall meet the dynamic brake test speci-fied in 6.2. Hand brake levers shall be located on the handle-bars in a position that is readily accessible to the rider in ther
18、ecommended use position. Hand brake levers shall have amaximum reach (dimension between the hand brake lever(s)and the handle bars) of not more than 89 mm (3.5 in.) at anypoint between the pivot point of the lever and the levermidpoint. At no point along the lever shall the grip dimensionexceed 102
19、mm (4 in.). An operating force of equal to or lessthan 44.5 N (10 lbf) applied to the hand lever at a point 25 mm(1.0 in.) from the open end of the hand lever shall cause thebrake to begin its retarding function.5.2 Electrical Systems:5.2.1 All vented batteries shall have a vent tube, which ispointe

24、sition. 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.5.4 Curb Impact TestsUnits shall be tested per 6.1.F26410825.5 Folding Mechanis
25、ms, Hinges, and ClearancesThisrequirement is intended to eliminate possible crushing, lacera-tion, or pinching hazards that might occur in folding mecha-nisms and hinges. Examples are the motion of a hinge thatproduces a scissor action and the changing clearances at thehinge line between two hinged
26、portions, such that the gap willadmit 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 clearance requirements listed reflect thedifferent modes of entrapment or p
27、inching 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 the accessible gap at the hinge line willadmit a 5-mm (316-in.) dia
28、meter 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 Accessible Clearances for Moveable SegmentsThisrequirement concerns
29、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-mm (12-in.) diameter rod to prevent the trapping offingers.5.5.4 Ina
30、ccessibility 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 attachments,and brush-bar attachments shall be locking fasteners.5.7

32、 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 of the sprockets orpulleys of drivetrains (chain and sprocket or belt
33、 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 inspection and mainte-nance of the drivetrain. The inside and bottom
34、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 drivetrain warning shall bepermanently engraved, stamped, or applied to
35、the guard. Thewarning shall read “WARNINGKeep away from movingparts” or equivalent.5.9 Dynamic StrengthAll units shall be tested per 6.3.5.10 Static StrengthAll units shall meet the static strengthtest specified in 6.4.5.11 Wheel RetentionAll units shall meet the wheel re-tention test specified in 6
