ASTM E 84 test method for surface burning

ASTM E 84-06: standard test method for surface burning characteristics of building materials

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 Steiner Tunnel Test (Flame Spread Test)

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 <25 materials, 25 <FSI <100 can only be used for fire protection material is not very demanding place, and FSI> 100 of the material does not meet flame retardant requirements.

A class for the 0-25, B class for the 26-75 C Class 76-200, smoke index of less than 450
