1、Designation: F2907 13aConsumer 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 parentheses ind
2、icates 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 carriers. In
3、 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 intended
4、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 warnings prov
5、ided 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 from the n
6、ormal 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 from birth (full term infant weighing 8 lb (3.6 kg) ormore) through 35 lb (15.9 kg), in an upright or reclined
7、position, while being supported by the caregivers torso.1.4 The sling carrier is normally “worn” by the caregiver,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 awa
8、yfrom the caregiver or reclined on the front only of thecaregiver.1.5 No sling carrier produced after the 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 herei
9、n.1.6 This consumer safety specification is not intended toaddress incidents and injuries resulting from 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
10、in parentheses are mathematicalconversions to SI units that are provided for information onlyand are not 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 app
11、ro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.

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
40、 sling carrier is manufactured in multiple sizes, the size thatfits the test torso is the required 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), whicheve
41、ris greater, in the support area of the sling carrier. Include theweight of the weld cap in the 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 Fas
42、ten 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 required size for the sample submission.7.2.2 Position a weight of 35 lb (15.9 kg) usinga6t
43、o8in.diameter shot bag a distance of 1 in. (25 mm) above the supportarea of the sling carrier. 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
44、 anyhardware and is fastened by means of fabric, mark the positionon the fabric. This will be the start point of the remainder of thetest.7.2.3 Drop the weight onto the support area an additional1000 times with a cycle time of 4 6 1s/cycle. If the sling,according to manufacturers instructions, has m

46、 cannot be removed, ittears into pieces upon removal, or such action damages thesurface to which it is attached.7.3.2 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 solvents, it cannot beremoved or su
47、ch action damages the surface to which it isattached.7.3.3 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 a 0.75 in.
