20.2

Test Procedure

20.2.1 Attach a strip of supplied-air suit material to clamp.

20.2.2 Apply a 1-inch high Bunsen burner flame to the bottom end of the test strip

until it is ignited, but not longer than 15 s. If the material does not ignite, it

should be considered nonflammable.

20.2.3 If the specimen ignites, the test should begin when the charred edge reaches

the lower gauge mark. If the flame is extinguished before reaching the upper

gauge mark (12 inches) and if the extinguishment is not due to the specimen

separating and causing the burning part to drop off, the material should be

considered self-extinguishing. If the specimen burns the full 12 inches or if

the flame is extinguished because the specimen separates allowing the flame

to drop off, the material should not be acceptable.

20.3

Nonattached gloves and shoe covers, materials covered by self-extinguishing

materials, breathing air hoses, and tape used to attach gloves to the supplied-

air suit do not require this test.
