1、Designation: F1235 03 (Reapproved 2008)F1235 14Standard Consumer Safety Specification forPortable Hook-On Chairs1This standard is issued under the fixed designation F1235; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of
2、 last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () 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 iden
3、tified by the United States 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 ov
4、er. In response to a review 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
5、does not cover chairs that 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
6、 will be updated whenever substantive information becomes available that necessitatesadditional requirements or justifies revising the existing requirements.1. Scope1.1 This specification covers the performance requirements and test methods designed to ensure the satisfactory performanceof the porta
7、ble hook-on chair.1.2 This specification is intended to minimize injuries to children resulting from normal use and reasonably foreseeable misuseor 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 and holding a child who can r
8、emain in a sitting position due to his or herown coordination.1.3.2 Usually a legless seat constructed to locate the occupant at a table in such a position and elevation so that the surface ofthe table can be used as the feeding surface for the occupant.1.3.3 Supported solely by the table on which i
9、t is mounted. These chairs are intended for use by children between the ages ofsix months and three years and who weigh no more than 37 lb (16.8 kg) (95th percentile male at three years).1.4 No chair produced after the approval date of this consumer safety specification shall, either by label or oth
10、er means, indicatecompliance with this specification unless it conforms to all applicable 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 information
11、only and are not considered standard.1.6 The following precautionary caveat pertains to the test methods portion only, Section 7, of this specification: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 thisst
12、andard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.1 This specification is under the jurisdiction of ASTM Committee F15 on Consumer Products and is the direct responsibility of Subcommittee F15.16 on Highchairs,Hook-On C
