Building Materials Surface Burning Characteristics Test Apparatus Meeting ASTM E84 Standard

This method is applicable to determine surface burning characteristics of building materials and flame propagation rate of exposed surfaces such as walls and ceilings (including solid plastics), at the same time measure smoke density.

This test method applies to the exposed surface which includes ceiling or walls, provided that the materials or the whole assembly, with its own structural quality or the aspect in which is tested and intended to use is able to support itself in position or being supported during the period of test. The method is used to determine the corresponding burning behavior of the material by observing the flame spread along the test specimen. Reports are made for the flame spread and smoke density developed and it is not necessarily a relationship between the two measurements.

Standard:

ASTM E84: standard test method for surface burning characteristics of building materials UL723: test for surface burning characteristics of building materials

Parameters:

1. Power: AC380V±10%

2. Max Power: 5KW

3. Test tunnel furnace: length 7.62M, open end cross section 0.45M * 0.3M, firebrick max temperature 2500℃

4. The test chamber is made of 16 isometric observation windows, and one fire observation window, which is a double-layer high-temperature quartz glass, SUS304 stainless steel frame.

5. Adopt water seal structure, the two sides of sample cover plate are broken into the tank during test, in order to sealing performance is better.

6. Air inlet is adjustable shutter, which could control air flow inside furnace more accurately.

7. Thermocouple: K-type, diameter 3mm, 3 sets, Omega USA imported, high precision, long service life, measuring range: ≤1300 ℃

8. Exhaust port: which is from rectangle to round, diameter 406mm

9. Smoke density measurement: install position is distance tunnel furnace 4.9~12.2M.

10. Gas burner installation: the burner shall be spaced 305mm from the fire end of the test chamber, and 190mm below the under surface of the test sample.
