PART 1633_STANDARD FOR THE FLAMMABILITY (OPEN FLAME) OF MATTRESS 
SETS--Table of Contents

Sec.  1633.3  General requirements.

    (a) Summary of test method. The test method set forth in Sec.  
1633.7 measures the flammability (fire test response characteristics) of 
a mattress specimen by exposing the specimen to a specified flaming 
ignition source and allowing it to burn freely under well-ventilated, 
controlled environmental conditions. The flaming ignition source shall 
be a pair of propane burners. These burners impose differing fluxes for 
differing times on the top and sides of the specimen. During and after 
this exposure, measurements shall be made of the time-dependent heat 
release rate from the specimen, quantifying the energy generated by the 
fire. The rate of heat release must be measured by means of oxygen 
consumption calorimetry.
    (b) Test criteria. (1) When testing the mattress set in accordance 
with the test procedure set forth in Sec.  1633.7, the specimen shall 
comply with both of the following criteria:
    (i) The peak rate of heat release shall not exceed 200 kilowatts 
(``kW'') at any time within the 30 minute test; and
    (ii) The total heat release shall not exceed 15 megajoules (``MJ'') 
for the first 10 minutes of the test.
    (2) In the interest of safety, the test operator should discontinue 
the test and record a failure if a fire develops to such a size as to 
require suppression for the safety of the facility.
    (c) Testing of mattress sets. Mattresses labeled for sale with a 
foundation shall be tested with such foundation. Mattresses labeled for 
sale without a foundation shall be tested alone.
    (d) Compliance with this standard. Each mattress set manufactured, 
imported, or renovated on or after the effective date of the standard 
shall meet the test criteria specified in paragraph (b) of this section 
and otherwise comply with all applicable requirements of this part 1633.
