KP8115 Building materials monomer products burning machine
1, scope of application:
Used to determine the construction materials or products (not including floor materials, and pointed out in the EC resolution 2000/147 / EC (goods) on the monomer burning test (SBI) reaction to fire performance of the method.
Conform to the standards: GB/T 20284 standard monomer burning test of building materials or products and EN13823 monomer combustion test method (SBI),
Three, the main performance parameters:
Test equipment including combustion, control room, trolley, exhaust pipe, data collection and analysis device, gas supply control device.
1, the combustion lab: W3000 L3000 * * H2400 (MM), the room there are links at the top of the sampling pipe gas collecting cover and exhaust pipes, trolley has natural air in and out of the space below. Test samples in the process of combustion heat and combustion products are out of the exhaust pipes. With brick build by laying bricks or stones becomes.
2, ignition source and placed on the trolley vertical corner, 31 kw propane burner right Angle box (high side length is 250 mm to 80 mm).
3, set up in the exhaust pipe have a comprehensive sampling area for placing sensors and sampling tube.
4, the smoke exhaust speed: 0.50 m3 / S ~ 0.65 m3 / S.
5, test indoor environment temperature measurement: 1 mm diameter of K type sheathed thermocouples, environmental stress test: + 200 pa.
6, platoon flue temperature measurement: diameter of 0.5 K type sheathed thermocouple imports.
7, temperature measurement accuracy: 0.5 ℃.
8, high precision pressure sensor, smoke evacuation and accuracy of + / - 2 pa
9, the precision of time recording system: 0.1 S.
10, test time: 1 ~ 30 minutes.
11 and the smoke density measurement system, to test the smoke density in the process of measurement.
12, gas analyzer, and the key parts are imported.
13, with embedded computer and a 8.4 -inch LCD display, with TCP/IP and a variety of communication interface RS - 232 option
14, oxygen measurement:
14.1 measuring range: 0-25%
14.2, signal output: 4-20 ma; 14.4, the environment temperature: 0-45 ℃;
14.5, the relative humidity: < 90% (without condensate);
14.6, linearity: < + 0.1% O2;
14.7, the zero drift: 0.05% O2 (a week);
14.3, T90 response time: 2 s or less;
14.8, repeatability: < + 0.02% O2;
15, carbon dioxide (CO2) measurements:
15.1, measuring range: 0-10%
15.2, repeatability: < + / - 1%
Zero drift: 2% per week or less
Span drift: 2% per week or less
15.3, linear deviation: "+ / - 1%
15.4, response time, T90 2 seconds or less
16, record data acquisition system can collect oxygen concentration, co concentration, temperature, smoke density, heat release rate
Rate, mass loss rate, etc. Test data can be saved.
