Building Material Decomposition Smoke Density Tester Can Also Be Used For The Determination Of Static Smoke Production When Other Solid Materials Are Burning

Scope of application

It is mainly applicable to the determination of static smoke production when building materials and their products are burning, and can also be used for the determination of static smoke production when other solid materials are burning.

Compliance with standards: Complies with the requirements of GB/T8627-2007, ASTM D2843, and DIN4102 test standards.

Main parameters
1. Gas source: Propane gas with a purity of ≥95%, or gas of equivalent purity (provided by the user);
2. Combustion lamp: It is a Bunsen burner, with a length of 260mm and a nozzle diameter of 0.13mm, forming a 45° Angle with the smoke box.
3. Photoelectric system: The light source is a bulb, with a power of 15W and a working voltage of 6V.
4. Exhaust system: This machine is equipped with a powerful exhaust fan, which can expel the waste gas outdoors after the test.
5. Smoke density measurement range: 0 to 100%;
6. Accuracy of smoke density measurement: ±3%
7. Receiver: It is a silicon photovoltaic cell, with a light transmittance of 0% when completely blocked and 100% when unobstructed (calibrated through a filter).
8. Receiving lens focal length: 60-65mm;
9. Main burner working pressure: 276KPa (adjustable);
10. Auxiliary burner pressure: 138KPa (adjustable);
