2、heses 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 identifi
3、ed 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 cha
4、ir 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 eit
5、her 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 specificati
6、on 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 satisfactoryperformanc
7、e of the high chair. chair and high chairs created by using a high chair conversion kit and component(s) from anotherproduct.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 1
8、This consumer safety specification is not intended to address accidents and injuries resulting from the interaction 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 specificat
9、ion, a high chair is a free standing chair that elevates a child to standarddining table height. The high 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 childschilds own coordination, and normally for the purposes of feeding or
10、eating.Ahigh chair may be heightadjustable and include a reclined position for infants not able to remain in a sitting position due to the childschilds owncoordination.1.4 No high chair or high chair conversion kit produced after the approval date of this consumer safety specification shall, eitherb
11、y 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 provided for informat

It is the responsibility of the user of t
13、hisstandard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.1 This consumer safety specification is under the jurisdiction of ASTM Committee F15 on Consumer Products and is the direct responsibility of Subcommittee F15.16on
