Irradiance to the specimen during the test should be kept
constant. Three specimens should be tested under each of the following
conditions:
-
.1 irradiance of 25kW/m2 in the presence
of pilot flame;
-
.2 irradiance of 25kW/m2 in the absence
of pilot flame; and
-
.3 irradiance of 50kW/m2 in the absence
of pilot flame.
