3、entified by the United States Consumer Product Safety Commission (CPSC). CPSC has identifiedhazards resulting in injuries that occurred when children fell from booster seats, tipped over and outof a booster seat, among other types of incidents. In response to a review of the data received by theCPSC
4、, this specification attempts to minimize the following: incidents related to tray disengagement,restraint disengagement or absence of restraint system, stability of a booster seat while attached toadult chairs and entrapment within a booster seat, in addition to other hazards presented during the u
5、seof booster seats. This specification does not cover booster seats that were either blatantly misused orused in a careless manner that disregards the warning statements and safety instructions provided witheach booster seat. This specification is written within the current state-of-the-art of boost
6、er seattechnology. It is intended that this specification will be updated whenever substantive informationbecomes available that necessitates additional requirements or justifies the revision of the existingrequirements.1. Scope1.1 This consumer safety specification covers the perfor-mance requireme
7、nts and methods of test to ensure the satis-factory performance of the booster seat.1.2 This consumer safety specification is intended to mini-mize injuries to children resulting from normal usage andreasonably foreseeable misuse or abuse of booster seats.NOTE 1This consumer safety specification is
8、not intended to addressaccidents and injuries resulting from the interaction of older children withchildren in booster seats.1.3 For purposes of this consumer safety specification, abooster seat is a juvenile chair, which is placed on an adultchair to elevate a child to standard dining table height.
9、 Thebooster seat is made for the purpose of containing a child, upto 5 years of age, and normally for the purposes of feeding oreating. A booster seat may be height adjustable and include areclined position.1.4 No booster seat produced after the approval date of thisconsumer safety specification sha
10、ll, either by label or othermeans, indicate compliance with this specification unless itconforms to all requirements contained herein.1.5 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
11、 information onlyand are not considered standard.1.6 The following precautionary caveat pertains only to thetest method portion, Section 7, of this specification: Thisstandard does not purport to address all of the safety concerns,if any, associated with its use. It is the responsibility of the user
12、of this standard to establish appropriate safety and healthpractices and determine the applicability of regulatory limita-tions prior to use.1.7 This international standard was developed in accor-dance with internationally recognized principles on standard-ization established in the Decision on Prin
