3、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, this specification attempts to minimize the f

4、ollowing: 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 useof booster seats. This specification does not

5、 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 booster seattechnology. It is intended that this spe

6、cification 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 requirements and methods of test to ensure the satisfacto

7、ryperformance 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 specification is not intended to address accidents and injuries resu

8、lting 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 height. The booster seat is made for the purpose of cont

9、aining 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 specification shall, either by label or other means,indicate c
