AWTA TEST CODE

:

T17AW

TEST METHODS

:

BS3119

:

Test Equipment Flameproofness

PRINCIPLE

:

Determining whether a material is flameproof. Material is suspended vertically and the lower end is ignited. The duration of flaming, after the removal of the igniting flame, is timed and any spread of after-glow, after the flame has expired, is observed.

It may be necessary to subject material to a washing pretreatment to establish the durability of the flameproof quality.

PROCEDURE

:

Six test specimens 318mm long x 51mm wide three in length and three in width direction.

Apply burner flame for 12 seconds and then record time during which flaming continues on the test specimen and the area of flaming and the extent of after-glow is observed.

Using 10% of weight which is required to tear unburned material tear burned material to obtain char length.

Flameproofness requirements: No test specimen shall continue to flame for more than 8 seconds after the igniting flame has been removed. After-glow shall not spread beyond the area of material damaged by flaming. The average length of material which chars or melts on the six specimens shall not exceed 85mm and the maximum length of charred or melted material in any one specimen shall not exceed 114mm.

MATERIAL

:

Single piece one metre square.

SERVICE TARGET

8 days

COST

:

See Fee List.

PROBAN TESTS

:

eg. as for Albright and Wilson, materials boil for six hours prior to above test procedure. (Wash procedure - Defence (Aust) 5037-AIS)
