ASTM E84 Fire Test to Building Material – Standard
ASTM E84 Standard test method for surface burning characteristics of building materials
ASTM E84 Fire Test to Building Material – Standard Brief
Flame spread is the development of the flame in the surface, it is related to a fire near combustible Ershi believed the spread of fire. Flame propagation properties of the tunnel method and often radiation plate test.
ASTM E84 Fire Test to Building Material –Test Method
Tunnel test is to test the surface burning characteristics of materials, asbestos and untreated red oak plywood compared. 0 levels of asbestos plywood, 100 level for the untreated red oak flooring. In this test, the smoke produced during combustion also be measured, and divided into within the same class. This level within 10 minutes in the beginning was determined. However, the difference is coated with fire, building specifications to extend the test time from 10 minutes to 30 minutes, the burner flame propagation can not exceed 10 1 / 2 feet, and requires no further signs of burning
Determination of the material with the tunnel of FSI between the value of between 0 to 200, FSI smaller the value of material, the smaller the risk of fire. High-rise building and the corridor should be used FSI( Flame spread Test) <25 materials, 25 100 of the material does not meet flame retardant requirements.
ASTM E84 Fire Test to Building Material –Products Classification
ASTM E84 Class A for the 0-25,smoke index of less than 450
ASTM E84 Class B for the 26-75, smoke index of less than 450
ASTM E84 Class C for the 76-200, smoke index of less than 450
