Introduction
GD-AS1530 Building Material Radiant Panel Tester is designed according to AS/NZS1530.3;
The device heat samples via a gas radiant plate and calibrate with a heat flow meter. Test sample is placed in a vertical position, near the radiation plate, exposed in a clear area calibrated radiation flux.
Close to the pilot flame is assembled with the test sample, but not in contact with the test sample.
After ignition, it can record ignition time, flame propagation time, heat release integral, smoke Release, etc.
Feature
1, All structural components are made of stainless steel, nice appearance, corrosion resistance;
2, Sample fixture could be movable to adjust the distance to the radiant panel.
3, Ignition sources: radiation plate and two pilot flame burners;
4, One pilot flame burner is fixed before the sample at 15mm from the front face of the sample and 50mm above the center of the samples. And the other burner could be moved before the sample.
5, Flame height is controlled by the imported flow control meter.
6,Samples size: 710mmx610mm;
7, Stainless steel hood and flue to collect the smoke of specimens. Hood size:1140mmx1140mm; smoke tube is dia.305mm;
8, Radiant panel size:300mmx300mm; With porous fire-brick surface.
9, Radiation plate temperature probe: prevent flames turned the heat radiating plate rear side;
10, Precise gas and airflow control to realized the radiant panel heat adjustment.
11, Provide Heat flux senor fixture to calibrate the radiation level according to standard request 2.4kw/m2;
12, Two shields could be removed as a standard request.
13,19" rack to measure the flame spread rate analysis, critical flow, heat release rate
14, Provide an exhaust fan.
Optical system
1, The optical system comprising a light source color temperature is 2900 ± 100 K incandescent, light-receiving silicon photodiode with an optical path test shutter, 0% and 100%, to facilitate the use of calibration;
2, Imported light battery module measuring light attenuation. The system automatically calculates and generates a light transmittance curve translucent; printable Scribble
3, One button automatic and five-level (0,25%,50%,75%,100%)calibration system by computer.
Test System
1, The United States imported Metherm thermopile type heat flow meter-Design range 0~10k W/m², the accuracy of heat flow meter is ± 3%, repeatability is ± 0.5%.
2, Gas supply: with a valve, zero-pressure valve, tempering valves, solenoid valves, and a mixer, the mixed air and fuel gas supplied to the radiation plate.
3, All radiant panel combustion control system safety explosion-proof, check valve, cut off the gas solenoid valve prevents the gas reflux
4, The camera can observe a situation and save the test program (Optional)
5, Data acquisition system can store the data of ignition time, flame propagation time, heat release integral,
smoke release, etc.
6, Radiation plate burner system is fully automated, with spark ignition and safety protection the system;
7, Labview control system, user-friendly, easy to operate, precise control;
8, Signal acquisition and processing module and the air volume control module circuit linked by a programmable logic controller;
9, 10kV spark ignition, with safety cease-fire devices.
10, Automatic ignition system; Automatic timing; Expire automatically turn off;
11, Window+Labview system to realize automatic test system
12, Equipped with audible alarm and alarm display function accidents.
13, The control box USB / RS232 serial port, external desktop/notebook computer operation control, free to print the test report.
14, GD-AS1530 Building Material Radiant Panel Tester has an automatic smoke density calibration system.
