1、Designation: F404 13aStandard 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
3、injuries 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
4、because 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
6、will 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 performanc
7、e of the high chair.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 consumer safety specification is not intended to addressaccidents and injuries resulting from the i
8、nteraction of older children withchildren in the high chair or the accidents resulting from abuse and misuseby persons over three years of age.1.3 For purposes of this consumer safety specification, ahigh chair is a free standing chair that elevates a child tostandard dining table height. The high c
9、hair is made for thepurpose of holding a child, up to 3 years of age, who canremain in a sitting position due to the childs own coordination,and normally for the purposes of feeding or eating.Ahigh chairmay be height adjustable and include a reclined position forinfants not able to remain in a sitti
10、ng position due to the childsown coordination.1.4 No high chair produced after the approval date of thisconsumer safety specification shall, either by label or othermeans, indicate compliance with this specification unless itconforms to all requirements contained herein.1.5 The values stated in inch
11、-pound units are to be regardedas standard. The values given in parentheses are mathematicalconversions to SI units that are provided for information onlyand are not considered standard.1.6 The following precautionary caveat pertains only to thetest methods portion, Section 7, of this specification:
12、 Thisstandard does not purport to address all of the safety concerns,if any, associated with its use. It is the responsibility of the userof this standard to establish appropriate safety and healthpractices and determine the applicability of regulatory limita-tions prior to use.NOTE 2This consumer s
