Lab UL723 ASTM E84 Building Materials Surface Burning Characteristics Testing Equipment

Application

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

Power: AC380V±10%
Max Power: 5KW
Test tunnel furnace: length 7.62M, open end cross section 0.45M * 0.3M, firebrick max temperature 2500℃
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.
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.
Air inlet is adjustable shutter, which could control air flow inside furnace more accurately.
Thermocouple: K-type, diameter 3mm, 3 sets, Omega USA imported, high precision, long service life, measuring range: ≤1300 ℃
Exhaust port: which is from rectangle to round, diameter 406mm
Smoke density measurement: install position is distance tunnel furnace 4.9~12.2M.
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.
The light source: two gas burners, around nozzle distance 203mm, energy output 5.3Mj/min.
Ignition system: high voltage electronic ignition.

Component Material and Function

Test furnace size: L9456*W1067*H1400, not including flue.
Furnace base is made of 100*50 channel steel welded together, surface spray treatment
Flue: double-layer flue, the center filled with high temperature asbestos, inner layer SUS304 stainless steel plate, outer layer galvanized sheet with T1.2
Sample plate: calcium silicate cement board, high temperature resistant to 1300℃
Sample cover: T2.0 SUS304 stainless steel
Control box: adopts T1.2 cold plate, CNC machine tool is formed, arc shape beautiful, surface is white paint.

Gas and Gas Flow Control System

Gas: gas (purity 99%), by your own.
Gas control system, includes flow meter, U type pressure gauge, pressure gauge, pressure regulating valve.
Flow meter: domestic brand, range 2~20L/min, accuracy 2%.
U type pressure gauge: original from USA, water column 0~36 inches, analysis degree 0.1 inch.
Pressure gauge: 0~200Kpa(0~30psi), resolution 5Kpa.
Pressure regulating valve: 0~10kg/min continuously adjustable.

Smoke Density Measurement System

Light source: imported quartz halogen lamp.
Nominal power: 100W.
Nominal voltage: 12V.
Nominal light return amount: 2000~3000Lm.
Receiver: spectral response matches light meter of international lighting commissioner (CIE).
Installation: install at one end of the pipe with length 150, the other end is a dustproof window, inner wall of pipe is glossy black and anti-reflection.
Light transmittance 0% means no light passing, 100% means without shade, all pass through

Features

Measure flame propagation speed is based on the time of flame through the window to estimate after lit sample, get flame propagation speed curve, which method is to draw the distance and time flame propagation through window.
The flame propagation rate of various unprocessed wood is 60 to 230, the smoke generated is also measured during combustion, and its rank is divided in the same range.
The FSI value of the material measured with tunnel method is between 0 and 200, the smaller the FSI value is, the less the fire risk is.
Class A is 0-25, Class B is 26-75, Class C is 76-200, the sample that smoke index less than 450and flame spread rate curve, then calculate flame spread index(FSI) of the sample.

Control System

It adopts computer control system, includes PC and printer, Windows XP operate system.
It also includes light transmittance measurement software, which could output curves and reports.
All electronic originals are domestic leading brands, and all of them are directly manufacture by supplier, which could guarantee quality better.
The equipment has the following safety protection devices: power overload, short circuit protection and overload protection of control circuit.
