ASTME84 Standard Scope:
The ASTM E84 Standard Test Method for Surface Burning
Characteristics of Building Materials is one of the building codes'
most frequently specified standard test methods. Test and evaluate
your building product for compliance with building code
requirements with ICC NTA.
ASTM E84 standard applicable products:
Building materials, wallpaper, insulation materials, panel
products, paints, adhesives, sealants and coatings, interior
decoration.
ASTI E84 fire rating classification:
ASTM E84 Class is 0-25 mesh smoke index not exceeding 450.
ASTM E84 Class B is 26-75 day smoke index not exceeding 450.
ASTM E84 Class C 76-200 day smoke index not exceeding 450.
ASTm E84 test method for surface burning characteristics of
building materials:
1.ATM E84 test is carried out by placing a 24-inch wide x 24-foot
long sample into Stan's tunnel, where the test is carried out by
using two burners that provide 89 energy. During the 10-minute
test, the sample is installed under a removable cover on the
ceiling and forced ventilation is provided so that air and
combustion products move in the tunnel and enter the
exhaust/scrubber system.
2. The fire spread index (RS1) is calculated based on the data
recorded by the window of the ventilation room, and the computer
software records the flame spread curve during the test (0
minutes). The flame spread curve is calculated based on the data
recorded by the photometer system. The photometer system consists
of a light source, a photoelectric tube and a special electronic
device. The light passes through the ventilation room, and the
computer software records the light obstruction when the light
passes through the beam path during the test. The smoke area under
the smoke curve is used to calculate the smoke generation index.
4: Flame propagation refers to the development of flames on the
surface of materials. It is related to the fire signal and the
combustible material to expand the fire. The flame propagation
performance is often tested by enzyme method and radiation plate
method. This ASTHE84: method is used to determine the flame
propagation rate of building materials (determination of field
concentration), according to ASTMB84.
The equipment used in the ASTIE84 tunnel method is a steel trough
lined with refractory bricks with a length of 7.62m and an open end
cross-section of 0.45m*0.30m, with windows on the side of the
trough.
Suspension Hardware
1. Two station lift at the same time. Computer control ensures
smooth lifting.
2. Suspension Hardware can be moved up and down,left and right
which is convenient for sample installation and commissioning.
3. Equipped with safety protection platform, convenient for sample
installation and commissioning.
Combustion system
1.The 10kV spark igniter is equipped with a safety cease-fire
device.The igniter is automatically positioned through the lever
connected to the closing mechanism.
2.The combustion heat of the burner is automatically controlled by
the gas flow system. The reading accuracy is 1%.
3.The heat output of the burner can be automatically controlled by
computer. Equipped with Japanese mass flow controller.
4.Gas flow valve control system to avoid leakage caused by
electromagnetic valve failure, resulting in explosion risk.
5.Frequency fan automatically controls wind speed inside the flue,
fan power 3KW, voltage 380V
6.Gas pressure gauge and pressure regulating valve to control gas
pressure accurately.
7.The Steiner Tunnel Test Furnace adopts imported gas flow control
valve to control gas flow accurately
Test System
1.Smoke Density Test:smoke density is measured by incandescent
light system.Color temperature 2900±100K;The current fluctuation
range is + 0.5%;Linear output of smoke density value;With time
compensation function.
2.The lens converts light into 20mm parallel beams; d/f < 0.04.
3.Detector:The spectral distribution corresponds to CIE;The
accuracy of the chromatic standard function is + 5%;Thelinearity of
output is less than 3% of transmittance or 1% of absolute
transmittance.;The response time of system 90% is no more than 3S
4.The thermocouple is K type armored thermocouple, 0.5mm diameter;
the temperature accuracy is 0.5 degrees.
5.Pressure sensor range 0~100pa; accuracy is + 2pad;The response
time of pressure sensor 90% is 1s.
6.Environmental pressure accuracy of + 200Pa
7.System record time is at least 3S
8.System time recording accuracy 0.1s
9.Computer real-time display of smoke density generation curve
10.Option:The system is equipped with a camera system to observe
the experimental process and record the characteristics of the
burner residue after the implementation and combustion of the
sample.
