(b) Manufacturers are encouraged to conduct, as part of the quality assurance program, random testing of mattress sets being produced for sale according to the requirements of §§ 1633.3 and 1633.7.

(4) For subordinate prototypes, the prototype identification number of the qualified or confirmed prototype on which the mattress set is based, and, at a minimum, the manufacturing specifications and a description of the materials substituted, photographs or physical specimens of the substituted materials, and documentation based on objectively reasonable criteria that the change in any component, material, or method of assembly will not cause the subordinate prototype to exceed the test criteria specified in § 1633.3(b).

(n) Qualified prototype means a prototype that has been tested in accordance with § 1633.4(a) and meets the criteria stated in § 1633.3(b).

(a) Except as otherwise provided in paragraph (b) of this section, each manufacturer shall cause three specimens of each prototype to be tested according to § 1633.7 and obtain passing test results according to § 1633.3(b) before selling or introducing into commerce any mattress set based on that prototype, unless the manufacturer complies with the prototype pooling and confirmation testing requirements in § 1633.5.

(3) The manufacturer producing mattress sets in reliance on a qualified prototype has performed a confirmation test on at least one (1) Specimen of the mattress set it produces in accordance with § 1633.7. The tested specimen must meet the criteria under § 1633.3(b) before any mattress sets based on the qualified prototype may be sold or introduced into commerce.

(1) If any test performed for quality assurance yields results which indicate that any mattress set of a production lot does not meet the criteria of § 1633.3(b), or if a manufacturer obtains test results or other evidence that a component or material or construction/assembly process used could negatively affect the test performance of the mattress set as set forth in § 1633.3(b), the manufacturer shall cease production and distribution in commerce of such mattress sets until corrective action is taken.
