Sec.  1633.6  Quality assurance requirements.

    (a) Quality assurance. Each manufacturer shall implement a quality 
assurance program to ensure that mattress sets manufactured for sale are 
the same as the qualified and/or confirmed prototype on which they are 
based with respect to materials, components, design and methods of 
assembly, except as permitted by Sec.  1633.4(b). At a minimum these 
procedures shall include:
    (1) Controls, including incoming inspection procedures, of all 
mattress set materials, components and methods of assembly to ensure 
that they are the same as those used in the prototype on which they are 
based;
    (2) Designation of a production lot that is represented by the 
prototype; and
    (3) Inspection of mattress sets produced for sale sufficient to 
demonstrate that they are the same as the prototype on which they are 
based with respect to materials, components, design and methods of 
assembly.
    (b) Production testing. 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 Sec.  Sec.  
1633.3 and 1633.7.
    (c) Failure of mattress sets produced for sale to meet flammability 
standard--(1) Sale of mattress sets. 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 Sec.  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 Sec.  
1633.3(b), the manufacturer shall cease production and distribution in 
commerce of such mattress sets until corrective action is taken.
    (2) Corrective action. A manufacturer must take corrective action 
when any mattress set manufactured or imported for sale fails to meet 
the flammability test criteria set forth in Sec.  1633.3(b).
