1、Designation: F2907 14bF2907 15Standard 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 i
2、n parentheses 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 s
3、ling carriers. 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 specifica
4、tion is 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
5、 or warnings 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 occu
6、pant from 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 in an upright or reclined position while being supported by the caregivers torso. In general,
7、the child will be between fullterm birth and 35 lb (15.9 kg).NOTE 1Slings consist of a variety of unstructured designs ranging from a hammock-shaped product suspended on the caregivers upper torso to along length of material wrapped around the caregivers body.1.4 The sling carrier is normally “worn”
8、 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 towards or away fromthe caregiver or reclined on the front only of the caregiver.1.5 No sling carrier produc
9、ed 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 contained herein.1.6 This consumer safety specification is not intended to address incidents and injuries
10、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. The values given in parentheses are mathematicalconversions to SI units that are provided for information
11、 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 to establish appropriate safety and health practices and determine the applicability of regulatorylimi
