1、Designation: F 1235 03Standard Consumer Safety Specification forPortable Hook-On Chairs1This standard is issued under the fixed designation F 1235; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A number
2、 in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.INTRODUCTIONThis consumer safety specification addresses incidents associated with portable hook-on chairs(chairs) that were identified by the United St
3、ates Consumer Product Safety Commission (CPSC).CPSC has identified injuries which occurred when chairs fell because the child pushed off the table,components of the chair became detached or broke, and, to a lesser extent, when the table to whichthe chair was attached tipped over. In response to a re
4、view of the data received by the CPSC, thisspecification attempts to minimize the following: falls due to detachment of the chair from the tableor due to breakage or detachment of components; a child falling out of the chair; and chair and tabletipping over.This specification does not cover chairs t
5、hat are either blatantly misused or are used in a carelessmanner that disregards the warning statements and safety instructions provided with each chair. Thisspecification is written within the current state-of-the-art of chair technology. It is intended that thisspecification will be updated whenev
6、er substantive information becomes available that necessitatesadditional requirements or justifies revising the existing requirements.1. Scope1.1 This specification covers the performance requirementsand test methods designed to ensure the satisfactory perfor-mance of the portable hook-on chair.1.2
7、This specification is intended to minimize injuries tochildren resulting from normal use and reasonably foreseeablemisuse or abuse of chairs.1.3 For the purposes of this specification a chair is:1.3.1 A seat made for the express purpose of seating andholding a child who can remain in a sitting posit
8、ion due to hisor her own coordination.1.3.2 Usually a legless seat constructed to locate the occu-pant at a table in such a position and elevation so that thesurface of the table can be used as the feeding surface for theoccupant.1.3.3 Supported solely by the table on which it is mounted.These chair
9、s are intended for use by children between the agesof six months and three years and who weigh no more than 37lb (16.8 kg) (95th percentile male at three years).1.4 No chair produced after the approval date of thisconsumer safety specification shall, either by label or othermeans, indicate complianc
10、e with this specification unless itconforms to all applicable requirements contained herein.1.5 The values stated in inch-pound units are to be regardedas the standard. The SI units given in parentheses are forinformation only.1.6 The following precautionary caveat pertains to the testmethods portio

19、 sealed or glued together as an assembly.3.1.3 manufacturers recommended use positionany posi-tion that is presented as a normal, allowable, or acceptableconfiguration for the use of the product by the manufacturer inany descriptive or instructional literature. This specificallyexcludes positions th
