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 carri
3、ers. 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 in
4、tended 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 warnin
5、gs provided with theproduct, or both.)1. Scope1.1 This consumer safety specification establishes performance requirements, test methods and marking requirements topromote safe use of sling carriers.1.2 This consumer safety specification is intended to minimize the risk of injury to an occupant from
6、the normal use andreasonably foreseeable misuse of products.1.3 For purposes of definition, a sling carrier is a product of fabric or sewn fabric construction, which is designed to containa child from birth (full term infant weighing 8 lb (3.6 kg) or more) through 35 lb (15.9 kg), in an upright or r
7、eclined position, whilebeing 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 of thecaregiver. These products are worn on the front, hip or back of the caregiver, with the child either facing towar
8、ds or away fromthe caregiver or reclined on the front only of the caregiver.1.5 No sling carrier produced after the approval date of this consumer safety specification shall, either by label or other means,indicate compliance with the specification unless it complies with all of the requirements con
9、tained herein.1.6 This consumer safety specification is not intended to address incidents and injuries resulting from the interaction of otherpersons or objects with the caregiver and child while the sling carrier is in use.1.7 The values stated in inch-pound units are to be regarded as standard. Th
10、e values given in parentheses are mathematicalconversions to SI units that are provided for information only and are not considered standard.1.8 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibilityof the user of this standard
11、 to establish appropriate safety and health practices and determine the applicability of regulatorylimitations prior to use.2.

Test Methods7.1 Static Load Test:7.1.1 Fasten the sling carrier to a test torso (see Fig. 2) as directed in the instruction manual supplied with the product. If thesling carrier is manufactured in multiple sizes
42、, the size that fits 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 manufacturers maximummanufacturers recommended weight recommended weight, or 60 lb, whichever is greater, in the su
43、pport area of the sling carrier.Include the weight of the weld cap in the total. Gradually apply the weight within a 5-s period and maintain for an additional 1min.7.1.3 Repeat 7.1.1 and 7.1.2 for all manufacturers recommended usecarrying positions.7.2 Dynamic Load Test:7.2.1 Fasten the sling carrie
44、r to a test torso (see Fig. 2) as directed in the instruction manual supplied with the product. If thesling carrier is manufactured in multiple sizes, the size that fits the test torso is the required size for the sample submission.7.2.2 Position a weight of 35 lb (15.9 kg) using a 6 to 8 in. diamet
45、er shot bag a distance of 1 in. (25 mm) above the supportarea of the sling carrier. Drop the weight onto the support area ten times with a cycle time of 4 6 1s/cycle to preset the attachmentsystem. By some appropriate means, mark the position of the attachment system. If sling does not have any hard
46、ware and isfastened by means of fabric, mark the position on the fabric. This will be the start point of the remainder of the test.7.2.3 Drop the weight onto the support area an additional 1000 times with a cycle time of 4 6 1s/cycle. If the sling, accordingto manufacturers instructions, has more th
47、an one usagecarrying position, the 1000 cycles will be divided among the differentusagecarrying positions.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 remove itwithout the aid of tools or solven
48、ts, it cannot be removed, it tears into pieces upon removal, or such action damages the surfaceto which it is attached.7.3.2 A non-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 remo
49、ved or such action damages the surface to which it is attached.7.3.3 A warning label attached by a seam shall be considered permanent if it does not detach when subjected to a 15 lbf (67N) pull force applied in any direction most likely to cause failure using a 0.75 in. (19 mm) diameter clamp surface (see Fig. 4).Gradually apply the force over 5 s and maintain for an additional 10 s.7.4 Adhesion Test for Warnings Applied Directly onto the Surface of the Product:7.4.1 Apply the tape test defined in Test Methods D3359, Test Method
