1、Designation: F2907 14Standard 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 parenth
2、eses 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 carr
3、iers. 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 i
4、ntended 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 warni
5、ngs 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 fr
6、om 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 child
7、 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 ca
8、regiver,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 t
10、he 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 c
11、onsidered 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.

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
43、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), whicheveris greater, in the support area of the sling carrier. Include theweight of the weld c
44、ap 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 Fasten the sling carrier to a test torso (see Fig. 2)asdirected in the instruction manual
45、 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) usinga6to8in.diameter shot bag a distance of 1 in. (25 mm) above the supportarea of the sling
46、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 anyhardware and is fastened by means of fabric, mark the positionon the fabric. This
47、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 more than onecarrying position, the 1000 cycles will be divided among thedifferent carr
