Examination of Product

Where requirements are not supported by specific test procedures, products shall be examined

to determine conformance to this specification and the applicable SCD.

Flammability

4.6.7.1

Test Apparatus

The test shall be performed within a test chamber approximately 1 foot (0.30 m) square by

2 feet (0.61 m) in height, open at the top and front to provide adequate ventilation for

combustion but to prevent drafts. The specimen holder shall be so designed that the lower end

of a 24-inch (610-mm) specimen is held by a clamp, while the upper end of the specimen

passes over a pulley and can be suitably weighted to hold the specimen taut at an angle of

60 degrees with the horizontal, in a plane parallel to and approximately 6 inches (152 mm)

from the back of the chamber. The test flame shall originate from a Bunsen type gas burner

with a 0.250-inch (6.4-mm) inlet, a needle valve in the base for gas adjustment, a nominal bore

of 0.375 inch (9.5 mm), and a barrel length of approximately 4 inches (102 mm) above
