1、Designation: F404 10F404 13Standard 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.Anumber in parenth
2、eses indicates the year of last reapproval.Asuperscriptepsilon () 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 identifie
3、d 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 chai
4、r 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 eith
5、er 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 specificatio
6、n 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 performance requirements and methods of test to ensure the satisfactoryperformance
7、 of the high chair.1.2 This consumer safety specification is intended to minimize injuries to children resulting from normal usage and reasonablyforeseeable misuse or abuse of high chairs.NOTE 1This consumer safety specification is not intended to address accidents and injuries resulting from the in
8、teraction of older children withchildren in the high chair or the accidents resulting from abuse and misuse by persons over three years of age.1.3 For purposes of this consumer safety specification, a high chair is a free standing chair that elevates a child to standarddining table height. The high
9、chair is made for the purpose of holding a child, up to 3 years of age, who can remain in a sittingposition due to the childs own coordination, and normally for the purposes of feeding or eating. A high chair may be heightadjustable and include a reclined position for infants not able to remain in a
10、 sitting position due to the childs own coordination.1.4 No high chair produced after the approval date of this consumer safety specification shall, either by label or other means,indicate compliance with this specification unless it conforms to all requirements contained herein.1.5 The values state
11、d in inch-pound units are to be regarded as standard. The values given in parentheses are mathematicalconversions to SI units that are provided for information only and are not considered standard.1.6 The following precautionary caveat pertains only to the test methods portion, Section 7, of this sp
12、ecification: This standarddoes not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of thisstandard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.NOTE 2Th
