NBS Smoke Density ChamberZONSKY NBS Smoke Density Chamber measures smoke generation by tracking how much light is obscured by smoke particles over time, providing a quantitative assessment of smoke density. This test is widely used in safety regulations and standards to ensure that materials meet specific safety requirements.Talk To Our Team Compliance- BS EN ISO5659-2:2006 – Plastic—Smoke Generation—Part 2: Determination of Optical Density by a Single-Chamber Test

Main Technical Parameters| Parameter | Description |
|---|
| Equipment Composition | Includes test devices, test boxes, smoke density measurement devices, data acquisition systems, and compliance with GB/T 8323.2-2008 and ASTM E662. | | Smoke Density Test Box | Consists of a closed combustion test box, photometer measurement system, radiation cone device, combustion system, weighing instrument, igniter, test box bracket, temperature measuring instrument, and smoke density test software. | | Test Chamber | Dimensions: Width 914±3mm, Height 914±3mm, Depth 610±3mm. The inner and outer walls are made of corrosion-resistant stainless steel, ensuring easy cleaning and durability. | | Hinged Front Door | Designed for full opening. Equipped with a viewing window and a smoke-sealing rubber strip to prevent leaks. A ventilation slit is installed at the top of the viewing window. | | Outer Box | An integrated housing for ease of operation. Dimensions: Length 1522mm, Width 1016mm, Height 1016mm. | | Radiation Cone Device | Includes an electric heating tube, weighing unit, PID temperature controller, heat flow meter, sample box, ignition system, and conforms to GB/T 8323.1, GB/T 8323.2, ISO5659-2:2012, and other standards. | | Heat Radiation Power | The electric heating tube is 2500W, installed in a double-layer stainless steel shell filled with heat-resistant fiber. It produces 10kW/m²–50kW/m² radiation intensity at the sample surface center. During testing, the radiation intensity measured 25mm away from the sample center must be at least 80% of the central intensity. The control accuracy is ±0.6 kW/m². |
