24、of attachment, must meetapplicable requirements of Consumer Safety SpecificationF963.5.7 Scissoring, Shearing, or PinchingA product, whenfolded, when being unfolded, or when in the manufacturersrecommended use position, shall be designed and constructedto prevent injury to the occupant from any scis
25、soring, shearing,or pinching when members or components rotate about acommon axis or fastening point, slide, pivot, fold, or otherwisemove relative to one another. Scissoring, shearing, or pinchingthat may cause injury shall not be permissible when the edgesof the rigid parts admit a probe that is g
26、reater than 0.210 in.(5.30 mm) and less than 0.375 in. (9.50 mm) diameter at anyaccessible point throughout the range of motion of such parts.5.7.1 Products with locking mechanisms that meet therequirements of 5.8.3, to prevent folding and unfolding by achild, shall only be evaluated in the manufact
27、urers recom-mended use position.5.8 Folding Mechanisms and HingesThese requirementsare intended to eliminate possible crushing, laceration, orpinching hazards that might occur in folding mechanisms andhinges. Examples are the sudden collapse or unexpectedmotion of a folding mechanism or hinge that p
28、roduces a scissoraction; and the changing clearances at the hinge line betweentwo hinged portions, such that the gap will admit fingers at oneposition of the hinge but not at all positions.5.8.1 Folding MechanismsProducts shall have a lockingdevice or other means to prevent unexpected or suddenmovem
29、ent or collapse of the product, or have adequateclearance to provide protection for the fingers, hands, and toesfrom crushing or laceration in the event of sudden movementor collapse of the product.5.8.2 Locking devices and other means to prevent unex-pected or sudden movement or collapse of the pro
30、duct shallengage automatically when the product is placed in anymanufacturers recommended use position. Latches may bemanually activated to allow placement into the use position butmust engage automatically when released. During and uponcompletion of the testing in 6.1, the unit shall remain in itsr
31、ecommended use position.5.8.3 If a unit is designed with a locking device:5.8.3.1 Each single action device shall require a minimumforce of 10 lbf (45 N) to activate the release mechanism whentested in accordance with 6.2.5.8.3.2 Each double action locking device shall requireeither two consecutive
32、actions, the first of which must bemaintained while the second is carried out, or two separate andindependent single action locking mechanisms that must beactivated simultaneously to fully release. There are no forcerequirements for locking devices that are double action or aresingle action that are
33、 activated simultaneously.5.8.4 Hinge Line ClearanceProducts having a gap orclearance along the hinge line between a stationary portion anda movable portion shall be so constructed that, if the accessiblegap at the hinge line will admit a316-in. (5-mm) diameter rod,it will also admit a12-in. (13-mm)
34、 diameter rod at all positionsof the hinge.5.8.5 No product shall give the appearance of being in anymanufacturers recommended use position unless the lockingdevice is fully engaged.F2613 1025.9 Circular Holes in Rigid MaterialsThis requirement isintended to prevent finger entrapment (which may cut
35、off bloodcirculation) in accessible holes in sheet metal and other rigidmaterials (non-circular holes are believed to present no signifi-cant hazard of cutting off blood circulation in entrappedfingers). If an accessible, circular hole in any rigid material lessthan 0.062 in. (1.58 mm) in thickness
36、can admit a14-in.(6-mm) diameter rod to a depth of38 in. (10 mm) or greater, itshall also admit a12-in. (13-mm) diameter rod. The productshall be evaluated in all manufacturers recommended usepositions.5.9.1 RationaleBased on requirements for toys from Con-sumer Safety Specification F963, since the
37、age range ofchildren using folding chairs is similar to that for childrenusing toys.5.10 Labeling:5.10.1 Warning labels (whether paper or non-paper) shall bepermanent when tested in accordance with 6.3.5.10.2 Warning statements applied directly onto the surfaceof the product by hot stamping, heat tr
38、ansfer, printing, woodburning, and so forth shall be permanent when tested inaccordance with 6.4.5.10.3 Non-paper labels shall not liberate small parts whentested in accordance with 6.5.5.11 Protective ComponentsIf the child can grasp com-ponents between the thumb and forefinger or teeth (such ascap
39、s, sleeves, or plugs used for protection from sharp edges,points, or entrapment of fingers or toes), or if there is at leasta 0.040-in. (1.00-mm) gap between the component and itsadjacent parent component, such component shall not beremoved when tested in accordance with 6.6.5.12 Strength Requiremen
40、tsFolding chairs shall be testedin accordance with 6.7, and shall not generate any sharp edges,sharp corners, sharp points, or any scissoring, shearing or pinchpoints. The product shall remain functional upon completion ofthe testing. Some deformation of the chair is permissibleprovided that the pre
41、ceding requirements are met. Theserequirements shall apply to folding chairs with either rigidseating surfaces or sling-type flexible seating surfaces sus-pended from a frame (for example, directors chairs) regardlessof whether the available seating width of the chair is limited bya structure such a
42、s arm rests.6. Test Methods6.1 Locking Mechanisms:6.1.1 Erect the product in accordance with any manufactur-ers instructions.6.1.2 Secure the product so that the normal folding motionis not impeded.6.1.3 Apply a force of 45 lbf (200 N) to the product in thedirection normally associated with folding.
43、 Apply the forcegradually over a 5-s period and maintain for an additional 10 sbefore releasing the force.6.1.4 Perform this procedure five times within a 2-minperiod.6.2 Locking Test MethodWith the product in each of themanufacturers recommended use positions, gradually apply aforce of 10 lbf (45 N
44、) to the locking mechanism in the directiontending to unlock it. The locking mechanism shall not unlockuntil a minimum force of 10 lbf (45 N) has been achieved.6.3 Permanency of Labels and Warnings:6.3.1 A paper label (excluding labels attached by a seam)shall be considered permanent if, during an a
45、ttempt to removeit without the aid of tools or solvents, it cannot be removed, ittears into pieces upon removal, or such action damages thesurface to which it is attached.6.3.2 A non-paper label (excluding labels attached by aseam) shall be considered permanent if, during an attempt toremove it with
46、out the aid of tools or solvents, it cannot beremoved or such action damages the surface to which it isattached.6.3.3 A warning label attached by a seam shall be consid-ered permanent if it does not detach when subjected to a 15-lbf(67-N) pull force applied in any direction most likely to causefailu
