27、meet applicable requirements of Consumer Safety Specication F963. 5.7 Scissoring, Shearing, or PinchingA product, when folded, when being unfolded, or when in the manufacturers recommended use position, shall be designed and constructed to prevent injury to the occupant from any scissoring, shearing
28、 or pinching when members or components rotate about a common axis or fastening point, slide, pivot, fold, or otherwise move relativetooneanother.Scissoring,shearing,orpinchingthatmaycauseinjuryshallnotbepermissiblewhentheedgesoftherigid parts admit a probe that is greater than 0.210 in. (5.30 mm)
29、and less than 0.375 in. (9.50 mm) diameter at any accessible point throughout the range of motion of such parts. 5.7.1 Products with locking mechanisms that meet the requirements of 5.8.3, to prevent folding and unfolding by a child, shall only be evaluated in the manufacturers recommended use posit
30、ion. F261313 25.8 Folding Mechanisms and HingesThese requirements are intended to eliminate possible crushing, laceration, or pinching hazards that might occur in folding mechanisms and hinges. Examples are the sudden collapse or unexpected motion of a folding mechanismorhingethatproducesascissoract
31、ion;andthechangingclearancesatthehingelinebetweentwohingedportions,such that the gap will admit ngers at one position of the hinge but not at all positions. 5.8.1 Folding MechanismsProducts shall have a locking device or other means to prevent unexpected or sudden movement or collapse of the product
32、 or have adequate clearance to provide protection for the ngers, hands, and toes from crushing or laceration in the event of sudden movement or collapse of the product. 5.8.2 Locking devices and other means to prevent unexpected or sudden movement or collapse of the product shall engage automatical
33、ly when the product is placed in any manufacturers recommended use position. Latches may be manually activated to allow placement into the use position but must engage automatically when released. During and upon completion of the testing in 6.1, the unit shall remain in its recommended use position
34、 5.8.3 If a unit is designed with a locking device: 5.8.3.1 Each single action device shall require a minimum force of 10 lbf (45 N) to activate the release mechanism when tested in accordance with 6.2. 5.8.3.2 Each double action locking device shall require either two consecutive actions, the rst
35、of which must be maintained while the second is carried out, or two separate and independent single action locking mechanisms that must be activated simultaneously to fully release.There are no force requirements for locking devices that are double action or are single action that are activated simu
36、ltaneously. 5.8.4 Hinge Line ClearanceProducts having a gap or clearance along the hinge line between a stationary portion and a movable portion shall be so constructed that, if the accessible gap at the hinge line will admit a 3 16-in. (5-mm) diameter rod, it will also admit a 1 2-in. (13-mm) diame
37、ter rod at all positions of the hinge. 5.8.5 Noproductshallgivetheappearanceofbeinginanymanufacturersrecommendedusepositionunlessthelockingdevice is fully engaged. 5.9 Circular Holes in Rigid MaterialsThis requirement is intended to prevent nger entrapment (which may cut off blood circulation) in ac
38、cessible holes in sheet metal and other rigid materials (non-circular holes are believed to present no signicant hazard of cutting off blood circulation in entrapped ngers). If an accessible, circular hole in any rigid material less than 0.062 in. (1.58 mm) in thickness can admit a 1 4-in. (6-mm) di
39、ameter rod to a depth of 3 8 in. (10 mm) or greater, it shall also admit a 1 2-in. (13-mm) diameter rod. The product shall be evaluated in all manufacturers recommended use positions. 5.9.1 RationaleBased on requirements for toys from Consumer Safety Specication F963, since the age range of children
40、 using folding chairs and stools is similar to that for children using toys. 5.10 Labeling: 5.10.1 Warning labels (whether paper or non-paper) shall be permanent when tested in accordance with 6.3. 5.10.2 Warning statements applied directly onto the surface of the product by hot stamping, heat trans
41、fer, printing, wood burning, and so forth shall be permanent when tested in accordance with 6.4. 5.10.3 Non-paper labels shall not liberate small parts when tested in accordance with 6.5. 5.11 Protective ComponentsIf the child can grasp components between the thumb and forenger or teeth (such as cap
42、s, sleeves, or plugs used for protection from sharp edges, points, or entrapment of ngers or toes), or if there is at least a 0.040-in. (1.00-mm) gap between the component and its adjacent parent component, such component shall not be removed when tested in accordance with 6.6. 5.12 StrengthRequirem

The product shall remain functional upon completion of the testing. Some deformation of the chair is permissible provided that the preceding re
44、quirements are met. These requirements shall apply to folding chairs with either rigid seating surfaces or sling-type exible seating surfaces suspended from a frame (for example,directorschairs)regardlessofwhethertheavailableseatingwidthofthechairislimitedbyastructuresuchasarmrests. 5.13 StabilityAl
45、l chairs shall not tip over backward when tested in accordance with 6.8. 6. Test Methods 6.1 Locking Mechanisms: Mechanisms (for folding chairs and stools only): 6.1.1 Erect the product in accordance with any manufacturers instructions. 6.1.2 Secure the product so that the normal folding motion is n
46、ot impeded. 6.1.3 Applyaforceof45lbf(200N)totheproductinthedirectionnormallyassociatedwithfolding.Applytheforcegradually over a 5-s period and maintain for an additional 10 s before releasing the force. 6.1.4 Perform this procedure ve times within a 2-min period. 6.2 Locking Test MethodMethod (for f
47、olding chairs and stools only)With the product in each of the manufacturers recommended use positions, gradually apply a force of 10 lbf (45 N) to the locking mechanism in the direction tending to unlock it. The locking mechanism shall not unlock until a minimum force of 10 lbf (45 N) has been achie

F261313 36.3 Permanency of Labels and Warnings: 6.3.1 A paper label (excluding labels attached by a seam) shall be considered permanent if, during an attempt to remove it without the aid of tools or solvents, it cannot be removed, it tears into pieces upon removal, or such action damages the su
49、rface to which it is attached. 6.3.2 A non-paper label (excluding labels attached by a seam) shall be considered permanent if, during an attempt to remove it without the aid of tools or solvents, it cannot be removed or such action damages the surface to which it is attached. 6.3.3 Awarning label attached by a seam shall be considered permanent if it does not detach when subjected to a 15-lbf (67-N) pull force applied in any direction most likely to cause failure using a 3 4-in.
