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.

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.

1.6 The following precautionary caveat pertains only to the test methods portion, 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
