ASTM F1235-18 PDF Download

The ASTM F1235-18 standard is intended to assure the effective operation of portable hook-on chairs and to reduce injuries to children that may come from ordinary use or reasonably foreseen misuse or abuse.

The standard specifies a number of performance criteria and testing procedures that these chairs must meet. These tests consist of a chair drop test, a static load test, a seat and seat back disengagement test, a chair bounce test, a chair pull/push test, a chair assembly test for the latching mechanism, a torque test, a tension test, and a labeling test.

The standard stipulates that educational literature must be provided with the chairs in addition to the performance criteria. Information on assembly, maintenance, cleaning, using, folding, and warnings, where appropriate, should be included in this material.

It is significant to note that any chair made after the consumer safety specification's approval date must meet all applicable requirements in order to bear the symbol designating compliance with this standard.
