Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.INTRODUCTIONThis consumer safety specification addresses crib accidents that were identified by the U.S.Consumer Product Safety Commission (CPSC).CPSC received reports of stra

3、ngulations incidents associated with crib corner post extensions andincidents concerning failure of crib hardware and other structural components of cribs that alsoresulted in fatalitiesIn response to the accident data collected by the CPSC, this consumer safety specification attemptsto minimize the

4、 risk of injury or death due to: failure of mattress support hardware, failure of gluedor bolted connections, side latch failure, and dislodgment of teething rails. This safety specificationalso addresses incidents associated with poor maintenance or assembly by means of requirements forthe contents

5、 of instructional literature that must accompany a crib.1. Scope1.1 This consumer safety specification establishes perfor-mance requirements and test procedures to determine thestructural integrity of cribs. It also contains design require-ments addressing entanglement on crib corner post extensions

6、,and requirements for warning labels and instructional material.1.2 No crib produced after the approval date of this con-sumer safety specification shall, either by label or other means,indicate compliance with this specification unless it conformsto all requirements contained herein.1.3 The values

7、stated in inch-pound units are to be regardedas standard. The values given in parentheses are mathematicalconversions to SI units that are provided for information onlyand are not considered standard.1.4 The following safety hazards caveat pertains only to thetest methods portion, Section 7, of this

8、 specification: Thisstandard does not purport to address all of the safety concerns,if any, associated with its use. It is the responsibility of the userof this standard to establish appropriate safety and healthpractices and determine the applicability of regulatory limita-tions prior to use.2. Ref

Test Methods7.1 Spindle/Slat Static Load Strength:7.1.1 Spindle/slat static load test may be

35、performed eitherwith the crib assembled according to manufacturers instruc-tions with the mattress support in its lowest adjustable position,with casters removed and with the crib rigidly constrained orwith the spindle/slat assemblies removed from the crib andrigidly supported at the upper and lower

36、 horizontal rails inmanner that shall not interfere with a spindle/slat defectingunder the applied force.7.1.2 Gradually, over a period of not less than 2 s nor greaterthan 5 s, apply a 56.2-lb weight or force (25.5 kg or 250 N) atthe midpoint, between the top and bottom of the spindle/slatbeing tes

37、ted. This weight or force shall be applied through acontact area large enough to not cause visible indentation orcutting of the spindle/slat, but not wider that 1 in. (2.54 cm)when measured parallel to the longitudinal axis of the spindle/slat. This weight shall be maintained for 30 s.7.1.3 Test a m

38、inimum of 25 % of all slats. Test at least twoslats of any differing dimension, if available.7.1.4 End vertical rails that are joined between the slatassembly top and bottom rails are not considered slats and donot require testing to this procedure.7.2 Mattress Support System Vertical Impact Test:7.

39、2.1 GeneralThis test consists of dropping a specifiedweight repeatedly onto a foam pad supported by the cribmattress support system. The test assists in evaluating thestructural integrity of the crib assembly. Glue joints and othermeans of fastening are subjected to abusive loads and stresses.7.2.2

(343-mm)diameter) with a 0.125-in. (3-mm) radius to ease the edgebetween the circular contact surface and the vertical

41、 cylindricalsurface.7.2.2.3 The total weight shall be 45 lb (20.4 kg).7.2.2.4 The weight shall pivot freely.7.2.2.5 A 4-in.

42、ocedure for Vertical Impact Testing of Full-SizeCribs:7.2.3.1 The crib is to be assembled in accordance with themanufacturers instructions except that casters shall not beinstalled on the crib (see Fig. 3).7.2.3.2 The crib shall be prevented from sliding in a mannerthat does not prevent changes of a

43、ngle that may take place inthe crib structure (see Fig. 3).7.2.3.3 All testing shall be conducted with the mattresssupport in the lowest position.7.2.3.4 Allow the weight to free fall 6 in. (150 mm) on to theupper surface of the foam pad at a rate of 4 6 1 s/cycle for thefollowing number of cycles:7

44、.2.3.5 500 cycles within14 in. (6.4 mm) of the geometriccenter of the mattress area.7.2.3.6 100 cycles at each of two diagonally oppositecorners, centered 9 in. (230 mm) from the crib sides formingthe corner.7.3 Crib Side Test:7.3.1 GeneralThis test consists of repeatedly impacting acrib side bottom

45、 rail by a specified weight. After completingthe cyclic testing, structural integrity is tested by applying astatic pull to the side assembly followed by a torque test ofeach spindle or slat.FIG. 2 Typical Test FrameF1169 0937.3.2 Apparatus for Crib Side Cyclic TestThe apparatusfor the cyclic test (

46、see Fig. 4) includes the following:7.3.2.1 A 30-lb (13.6-kg) weight.7.3.2.2 A 0.375-in. (9-mm) thick 30 Type A durometerrubber pad large enough to cover the impact area.7.3.2.3 Impactor with a width of 1 in. (25 mm) and sufficientlength to extend across the full width of the bottom rail.7.3.3 Appara

48、tion at the base.7.3.4.3 Allow the 30-lb (13.6-kg) weight to free-fall 3 in.(76 mm) 250 times at a rate of 4 6 1 s/cycle such that itimpacts directly upon the 0.375-in. (9-mm) thick rubber padlocated on the top surface of the bottom rail between twoadjacent spindles or slats as near the center of th

49、e rail aspossible.7.3.5 Crib Side Static Test:7.3.5.1 Upon completion of the cyclic test, apply a weight of100 lb (45.4 kg) at the point of impact testing while the side issupported on the top rail at a point vertically in line with thepoint of weight application.7.3.5.2 The contact area for the load and reaction supportshall be the same as the impact area previously defined.7.3.5.3 Apply the weight gradually within a period of 5 sand maintain it for an additional 30 s.7.3.6 Crib Side Spindle/Slat Torque Test:7.3.6.1 Apply a torque of 30 lbf-in.
