3、at wereidentified 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 b
4、y theCPSC, 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 dur
5、ing the useof 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
6、 of booster 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 performance r
7、equirements and methods of test to ensure the satisfactoryperformance of the booster seat.1.2 This consumer safety specification is intended to minimize injuries to children resulting from normal usage and reasonablyforeseeable misuse or abuse of booster seats.NOTE 1This consumer safety specificatio
8、n is not intended to address accidents and injuries resulting from the interaction of older children withchildren in booster seats.1.3 For purposes of this consumer safety specification, a booster seat is a juvenile chair, which is placed on an adult chair toelevate a child to standard dining table
9、height. The booster seat is made for the purpose of containing a child, up to 5 years of age,and normally for the purposes of feeding or eating. A booster seat may be height adjustable and include a reclined position.1.4 No booster seat produced after the approval date of this consumer safety specif
10、ication shall, either by label or other means,indicate compliance with this specification unless it conforms to all requirements contained herein.1.5 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
11、 provided for information only and are not considered standard.1.6 The following precautionary caveat pertains only to the test method portion, Section 7, of this specification: This standarddoes not purport to address all of the safety concerns, if any, associated with its use. It is the responsibi
12、lity of the user of thisstandard to establish appropriate safety safety, health, and healthenvironmental practices and determine the applicability ofregulatory limitations prior to use.1.7 This international standard was developed in accordance with internationally recognized principles on standardi
