1、Designation: F404 18Standard Consumer Safety Specification forHigh Chairs1This standard is issued under the fixed designation F404; the number immediately following the designation indicates the year of originaladoption or, in the case of revision, the year of last revision. A number in parentheses
2、indicates the year of last reapproval. A superscriptepsilon () indicates an editorial change since the last revision or reapproval.INTRODUCTIONThis consumer safety specification addresses high chair incidents that were identified by the U.S.Consumer Product Safety Commission (CPSC).CPSC identified i
3、njuries to children associated with tray disengagement, falls resulting whenchildren stood up on the seat of a high chair, entrapment between the tray and the seat, and tipover.By far the most common injury resulted from children falling when they were able to stand up on theseat of the high chair b
4、ecause they were not secured by the restraining system. In response to theincident data developed by the Commission, this consumer safety performance specification attemptsto minimize the above listed problems.This consumer safety performance specification does not cover high chairs that are either
5、blatantlymisused or are used in a careless manner that disregards the warnings and safety instructions that areprovided with each high chair.This consumer safety performance specification is written within the current state-of-the-art of highchair technology. It is intended that this specification w
6、ill be updated whenever substantiveinformation becomes available that necessitates additional requirements or justifies the revision ofexisting requirements.1. Scope1.1 This consumer safety specification covers the perfor-mance requirements and methods of test to ensure the satis-factory performance
7、 of the high chair and high chairs createdby using a high chair conversion kit and component(s) fromanother product.1.2 This consumer safety specification is intended to mini-mize injuries to children resulting from normal usage andreasonably foreseeable misuse or abuse of high chairs.NOTE 1This con
8、sumer safety specification is not intended to addressaccidents and injuries resulting from the interaction of older children withchildren in the high chair or the accidents resulting from abuse and misuseby persons over three years of age.1.3 No high chair or high chair conversion kit producedafter
