FIRE TEST FOR FRP
|
|
1 Heat Source
|
The heat source for the fire tests
should be provided by a propane gas torch with a Sievert burner type No. 2944
giving a maximum flame temperature of 1600C and burning propane at the rate of
4110 grams per hour with a pressure of 2kgf/cm. The rate of burning should be
carefully controlled. The length of blue flame should be approximately
200mm.
|
2 Specimen
|
The specimen should be 450mm x 450mm cut
from a one metre square panel of the laminate to be tested. The specimen should
not incorporate any of the edges of the one metre square panel. The edges of
the specimen should be housed in a steel frame sufficiently to prevent them
igniting during the tests. The specimen should be cured for at least 28 days
before testing.
|
3 Test procedure
|
The specimen should be oriented
vertically in a draft free location, such that the tip of the blue flame, i.e.
the point of greatest heat, impinges on the centre of the specimen with the
flame normal to its surface. The non gel coat surface of the specimen should be
exposed to the flame. The flame should not burn through the specimen within 15
minutes.
