1、Designation: F2907 14aStandard Consumer Safety Specification forSling Carriers1This standard is issued under the fixed designation F2907; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A number in parent
2、heses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.INTRODUCTIONThis consumer safety specification is intended to address incidents reported by the U.S. ConsumerProduct Safety Commission (CPSC) relating to sling car
3、riers. In response to the incident datacompiled by the CPSC, this consumer safety specification attempts to minimize the hazards associatedwith these products from the following: (1) occupant retention, (2) deficiency of consumer educationregarding product use. This consumer safety specification is
4、intended to deal with reasonablyforeseeable use and misuse of the products. (This consumer safety specification does not apply toproducts that are blatantly misused, nor does it apply to products used by consumers in a carelessmanner that violate normal practice or disregard the instructions or warn
5、ings provided with theproduct, or both.)1. Scope1.1 This consumer safety specification establishes perfor-mance requirements, test methods and marking requirements topromote safe use of sling carriers.1.2 This consumer safety specification is intended to mini-mize the risk of injury to an occupant f
6、rom the normal use andreasonably foreseeable misuse of products.1.3 For purposes of definition, a sling carrier is a product offabric or sewn fabric construction, which is designed to containa child in an upright or reclined position while being supportedby the caregivers torso. In general, the chil
7、d will be betweenfull term birth and 35 lb (15.9 kg).NOTE 1Slings consist of a variety of unstructured designs rangingfrom a hammock-shaped product suspended on the caregivers upper torsoto a long length of material wrapped around the caregivers body.1.4 The sling carrier is normally “worn” by the c
8、aregiver,and thus the child is supported from one or both shoulders ofthe caregiver. These products are worn on the front, hip or backof the caregiver, with the child either facing towards or awayfrom the caregiver or reclined on the front only of thecaregiver.1.5 No sling carrier produced after the
9、 approval date of thisconsumer safety specification shall, either by label or othermeans, indicate compliance with the specification unless itcomplies with all of the requirements contained herein.1.6 This consumer safety specification is not intended toaddress incidents and injuries resulting from
10、the interaction ofother persons or objects with the caregiver and child while thesling carrier is in use.1.7 The values 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
11、considered standard.1.8 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to
12、 use.2.

(25 mm) and nopart of the test mass
42、shall pass below the bottom of the testtorso.6.3.2 When tested in accordance with 7.5, after the comple-tion of each phase of the test, the attachment system and therestraint system (if applicable) shall not be released, there shallbe no failures (as defined in 6.1), and no part of the test massshal
43、l pass below the bottom of the test torso.7. Test Methods7.1 Static Load Test:7.1.1 Fasten the sling carrier to a test torso (see Fig. 2)asdirected in the instruction manual supplied with the product. Ifthe sling carrier is manufactured in multiple sizes, the size thatfits the test torso is the requ
44、ired size for the sample submission.7.1.2 Using a 6 in. (150 mm) standard weld cap (see Fig. 3),center a weight equal to three times the manufacturersmaximum recommended weight, or 60 lb (27.2 kg), whicheveris greater, in the support area of the sling carrier. Include theweight of the weld cap in th
45、e total. Gradually apply the weightwithin a 5-s period and maintain for an additional 1 min.7.1.3 Repeat 7.1.1 and 7.1.2 for all manufacturers recom-mended carrying positions.7.2 Dynamic Load Test:7.2.1 Fasten the sling carrier to a test torso (see Fig. 2)asdirected in the instruction manual supplie
46、d with the product. Ifthe sling carrier is manufactured in multiple sizes, the size thatfits the test torso is the required size for the sample submission.7.2.2 Position a weight of 35 lb (15.9 kg) usinga6to8in.diameter shot bag a distance of 1 in. (25 mm) above the supportarea of the sling carrier.
47、 Drop the weight onto the support areaten times with a cycle time of 4 6 1s/cycle to preset theattachment system. By some appropriate means, mark theposition of the attachment system. If sling does not have anyhardware and is fastened by means of fabric, mark the positionon the fabric. This will be
48、the start point of the remainder of thetest.7.2.3 Calculate the variable X by dividing 1000 test cyclesby the total number of different manufacturers recommendedcarrying positions and rounding up to the nearest multiple of50. Substantially similar carrying positions shall be counted as1 position. If
49、 the manufacturer has more than 3 carryingpositions, X shall be 350. Drop the weight onto the supportarea an additional X times with a cycle time of 4 6 1s/cycle.Repeat the test for each different carrying position.7.3 Permanency of Labels and Warnings:7.3.1 A paper label (excluding labels attached by a seam)shall be considered permanent if, during an attempt 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.7.3.2
