A number in parentheses indi
2、cates 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 t
4、o 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 provi
5、ded 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 no
6、rmal 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 reclinedp
7、osition, 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 away
8、from 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 herein
9、.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 i
10、n 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 appr
11、o-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.
