§1632.7. Tape edge substitution procedure. — Inbound Citations

(j) Mattress prototype means mattresses of a particular design, sharing all materials and methods of assembly, but excluding differences in mattress size. If it has been shown as a result of prototype qualification testing that an upholstery material or core will not reduce the ignition resistance of the mattress prototype, substitution of another material for such material shall not be deemed a difference in materials for prototype definition. (See § 1632.31(c)(4) for records required to demonstrate that a change of materials has not reduced ignition resistance of a mattress prototype.) If it is determined or suspected that a material has influenced the ignition resistance of the mattress prototype, a change in that material, excluding an increase in thickness, shall be deemed a difference in materials for purposes of prototype definition unless it is previously shown to the satisfaction of the Consumer Product Safety Commission that such change will not reduce the ignition resistance of the mattress prototype. Ticking materials may be substituted in accordance with § 1632.6. Tape edge materials may be substituted in accordance with § 1632.7.

(3) The standard sets forth a test at § 1632.7 which may be used to demonstrate that the substitution of tape edge materials will not reduce the ignition resistance of a mattress prototype or a mattress pad prototype.

(5) Manufacturing specifications and description of any new ticking or tape edge material substituted in accordance with § 1632.6 or § 1632.7, with the identification number of the prototype involved.
