DX8362 Single Combustion Tester For Building Materials Or Products, GB/T 20284-2006

DX8362 Single Combustion Tester for Building Materials or Products

1. Scope of application:

A method used to determine the fire reactivity of building materials or articles (excluding flooring materials and products specified in EC Decision 2000/147/EC) in the Single Combustion Test (SBI).

2. Comply with the standard:

It meets the requirements of GB/T 20284-2006 standard "Monomer Combustion Test of Building Materials or Products" and the EN13823 "Monomer Combustion Test Method (SBI)" test standard requirements.

3. Performance parameters:

The equipment includes a combustion test room, a control room, a trolley, a smoke exhaust pipe, a data collection and analysis device, and a gas supply control device.

1.Combustion test room: L3000*W3000*H2400(MM), the top of the room is connected with the sampling pipe collection hood and smoke exhaust pipe, there is a space under the cart for air to enter and exit naturally. During the test, the heat released by the combustion of the sample and the combustion products should be discharged from the smoke exhaust pipe and built with a brick wall.

2. Ignition source, 31KW propane right-angle sandbox burner (side length 250MM and height 80MM) placed in the vertical corner of the cart.

3. A comprehensive sampling area is provided in the smoke exhaust pipe for placing sensors and sampling pipes.

4. Smoke exhaust speed: 0.50 cubic meters/s ~ 0.65 cubic meters/s.

5. The ambient temperature measurement in the laboratory: K-type armored thermocouple with a diameter of 1MM, environmental pressure test: ±200Pa.

6. Exhaust flue temperature measurement: imported K-type armored thermocouple with a diameter of 0.5.

7. Temperature measurement accuracy: 0.5°C.

8. High-precision pressure sensor for exhaust flue, with an accuracy of ±2Pa

9. Time recording system accuracy: 0.1S.

10. Test time: 1~30 minutes adjustable setting.

11. The smoke density measurement system can measure the smoke density in the test process.

12. The gas analyzer and key components are all imported originally.

13. With embedded computer and 8.4-inch LCD display, with TCP/IP and RS-232 communication interface options

14. Oxygen measurement:

2. Signal output: 4-20mA;

3. Response time T90: ≤2S;

4. Ambient temperature: 0-45°C;

5. Relative humidity: <90% (no condensation);

6. Linearity: <±0.1% O2;

7. Zero drift: 0.05% O2 (one week);

8. Repeatability: <±0.02% O2;

15. Carbon dioxide (CO2) measurement:

1. Measuring range: 0-10%

2. Refoldability: <±1% control cabinet internal structure

Zero drift: ≤2%/week

Range drift: ≤2%/week

3. Linearity: <±1%

4. Response time: T90≤2 seconds

16. The data acquisition system can collect and record test data such as oxygen concentration, carbon monoxide concentration, temperature, smoke density, heat release rate, mass loss rate, etc., which can be saved.
