This consumer safety specification covers the performance requirements and test methods designed to ensure the satisfactory performance, and hence, minimize injuries to children resulting from normal use and reasonably foreseeable misuse or abuse of portable hook-on chairs. Chairs that conform to this specification shall pass the following performance tests: chair drop test; static load test; seat and seat back disengagement test; chair bounce test; chair pull/push test; restraint system integrity and retention tests; chair assembly test for the latching mechanism to prevent unintentional folding; torque test; tension test; and labeling test. Instructional literature detailing information such as assembly, maintenance, cleaning, operating, folding, and warnings, where applicable, must be included.
This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.
1.1 This specification covers the performance requirements and test methods designed to ensure the satisfactory performance of the portable hook-on chair.
1.2 This specification is intended to minimize injuries to children resulting from normal use and reasonably foreseeable misuse 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 and holding a child who can remain in a sitting position due to his or her own 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 of the table can be used as the feeding surface for the occupant.
1.3.3 Supported solely by the table on which it is mounted. These chairs are intended for use by children between the ages of six 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 other means, indicate compliance 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 mathematical conversions to SI units that are provided for information 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 standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
