Terminology3.1 Definitions of Terms Specific to This Standard:3.1.1 childrens chair, nseating furniture with a rigidframe that is intended to be used as a support for the body,limbs, or feet of a child when sitting
17、 or resting in an upright orreclining position.3.1.2 childrens stool, nchildrens chair without back orarmrests.3.1.3 conspicuous, adjdescribes a label that is visible,when the unit is in a manufacturers recommended useposition, to a person standing near the unit at any one positionaround the unit bu
18、t not necessarily visible from all positions.3.1.4 folding chair, folding stool, na childrens chair orstool which can be folded for transport or storage.3.1.5 manufacturers recommended use position, nanyposition that is presented by the manufacturer in any descrip-tive or instructional literature as
19、 a normal, allowable, oracceptable configuration for use of the product. This specifi-cally excludes positions that the manufacturer shows in a likemanner in its literature to be unacceptable, unsafe, or notrecommended.3.1.6 non-paper label, nlabel material (such as plastic ormetal) that either will
20、 not tear without the aid of tools or tearsleaving a sharply defined edge or labels made from fabric.3.1.7 occupant, nthat individual who is in a product that isset up in one of the manufacturers recommended use posi-tions.3.1.8 paper label, nany label material that tears withoutthe aid of tools and
21、 leaves a fibrous edge.3.1.9 rigid frame, nconstructed with a frame of rigidmaterials such as wood, plastic, or metal.4. Calibration and Standardization4.1 All testing shall be conducted on a concrete floor thatmay be covered with18-in. (3-mm) thick vinyl flooring cover,unless test instructs differe
22、ntly.4.2 The unit shall be completely assembled, unless other-wise noted, in accordance with the manufacturers instructions.4.3 No testing shall be conducted within 48 h of manufac-turing.4.4 The product to be tested shall be preconditioned in aroom with ambient temperature of 73 6 9F (23 6 5C) for
23、atleast 1 h prior to testing. Testing shall then be conducted withinthis temperature range.4.5 All testing required by this specification shall be con-ducted on the same unit unless otherwise specified.5. General Requirements5.1 Prior to testing, any exposed wood parts shall be smoothand free of spl
24、inters.5.2 There shall be no hazardous sharp points or edges asdefined by 16 CFR 1500.48 and 16 CFR 1500.49 before orafter testing to this specification.5.3 There shall be no small parts, as defined by 16 CFR1501, before testing or liberated as a result of testing inaccordance with this specificatio
25、n.5.4 The paint and surface coating on the product shallcomply with 16 CFR 1303.5.5 There shall be no flammable solids as defined in 16 CFR1500.3 (c) (6) (vi) before or after testing in accordance withthis specification.5.6 Toy accessories attached to, removable from, or soldwith a product, as well
26、as their means of attachment, must meetapplicable requirements of Consumer Safety SpecificationF963.5.7 Scissoring, Shearing, or Pinching (for folding chairsand folding stools only)A product, when folded, when beingunfolded, or when in the manufacturers recommended useposition, shall be designed and
27、 constructed to prevent injury tothe occupant from any scissoring, shearing, or pinching whenmembers or components rotate about a common axis orfastening point, slide, pivot, fold, or otherwise move relative toone another. Scissoring, shearing, or pinching that may causeinjury shall not be permissib
28、le when the edges of the rigid partsadmit a probe that is greater than 0.210 in. (5.30 mm) and lessthan 0.375 in. (9.50 mm) diameter at any accessible pointthroughout 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 u
29、nfolding by achild, shall only be evaluated in the manufacturers recom-mended use position.5.8 Folding Mechanisms and Hinges (for folding chairs andfolding stools only)These requirements are intended to elimi-nate possible crushing, laceration, or pinching hazards thatmight occur in folding mechanis
30、ms and hinges. Examples arethe sudden collapse or unexpected motion of a folding mecha-nism or hinge that produces a scissor action; and the changingclearances at the hinge line between two hinged portions, suchthat the gap will admit fingers at one position of the hinge butnot at all positions.5.8.
31、1 Folding MechanismsProducts shall have a lockingdevice or other means to prevent unexpected or suddenmovement 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 pro
32、duct.5.8.2 Locking devices and other means to prevent unex-pected or sudden movement or collapse of the product 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
33、automatically when released. During and uponcompletion of the testing in 6.1, the unit shall remain in itsrecommended 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 whent
34、ested in accordance with 6.2.5.8.3.2 Each double action locking device shall requireeither two consecutive actions, the first of which must beF2613 142maintained while the second is carried out, or two separate andindependent single action locking mechanisms that must beactivated simultaneously to f
35、ully release. There are no forcerequirements for locking devices that are double action or aresingle action that are 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 tha
36、t, if the accessiblegap at the hinge line will admit a316-in. (5-mm) diameter rod,it will also admit a12-in. (13-mm) 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.5.
37、9 Circular Holes in Rigid MaterialsThis requirement isintended to prevent finger entrapment (which may cut 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 entrappe
38、dfingers). If an accessible, circular hole in any rigid material lessthan 0.062 in. (1.58 mm) in thickness 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 usep
39、ositions.5.9.1 RationaleBased on requirements for toys from Con-sumer Safety Specification F963, since the age range ofchildren using chairs and stools 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 accordan
40、ce with 6.3.5.10.2 Warning statements applied directly onto the surfaceof the product by hot stamping, heat transfer, 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
41、 Protective ComponentsIf the child can grasp compo-nents between the thumb and forefinger or teeth (such as caps,sleeves, or plugs used for protection from sharp edges, points,or entrapment of fingers or toes), or if there is at least a0.040-in. (1.00-mm) gap between the component and itsadjacent pa
42、rent component, such component shall not beremoved when tested in accordance with 6.6.5.12 Strength RequirementsProducts shall be tested inaccordance with 6.7, and shall not generate any sharp edges,sharp corners, sharp points, or any scissoring, shearing or pinchpoints. The product shall remain fun
43、ctional upon completion ofthe testing. Some deformation of the product is permissibleprovided that the preceding requirements are met. Theserequirements shall apply to products with either rigid seatingsurfaces or sling-type flexible seating surfaces suspended froma frame (for example, directors cha
44、irs) regardless of whetherthe available seating width of the product is limited by astructure such as arm rests.5.13 StabilityAll products shall not tip over backwardwhen tested in accordance with 6.8.6. Test Methods6.1 Locking Mechanisms (for folding chairs and foldingstools only):6.1.1 Erect the p
45、roduct 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. Apply the forcegradually over a 5-s period and maintain for an add
46、itional 10 sbefore releasing the force.6.1.4 Perform this procedure five times within a 2-minperiod.6.2 Locking Test Method (for folding chairs and foldingstools only)With the product in each of the manufacturersrecommended use positions, gradually apply a force of 10 lbf(45 N) to the locking mechan
47、ism in the direction tending tounlock it. The locking mechanism shall not unlock until aminimum 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 attempt to removeit with
48、out 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 without the aid of tools or
49、 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 causefailure using a34-in. (19-mm) diameter clamp surface (see Fig.1). Gradually apply the force over 5 s and maintain for anadditional 10 s.6.4 Adhesion test for warnings applied directly onto thesurface of the product.6.4.1 Apply the tape test defined in Test Method
