Sec.  1632.7  Tape edge substitution procedure.

    (a) Sections 1632.1 (j) and (k) provide in part that ``a change in 
existing material shall be deemed a difference in materials for purposes 
of prototype definition unless it is shown to the satisfaction of the 
Consumer Product Safety Commission that such change will not reduce the 
ignition resistance'' of the mattress prototype or the mattress pad 
prototype.
    (b) The Commission will regard a showing ``to the satisfaction of 
the Consumer Product Safety Commission'' to have been made with respect 
to materials substitution of items such as flange materials and tapes at 
the tape edge under the following circumstances:
    (1) The mattress or mattress pad prototype has been qualified 
previously under the provisions of Sec.  1632.3; and
    (2) A substitution of materials involving only tape edge 
construction is contemplated; and
    (3) A prototype mattress or mattress pad incorporating the 
substitute materials has been tested in accordance with applicable 
procedures in Sec.  1632.4 by placing 36 cigarettes (18 per

surface--9 bare and 9 two-sheet) at tape edge locations with no test 
failure as determined by applying the test criterion of Sec.  1632.3(b); 
and
    (4) Records are maintained setting forth the details of the 
materials substitution and showing the results of the testing referred 
to in paragraph (b)(3) of this section. The records are to be maintained 
in accordance with regulations established by the Consumer Product 
Safety Commission (see Sec.  1632.31).
