Product Details
ZY6166D-PC NBS Smoke Density Chamber
Brief Introduction
The ZONSKY NBS Smoke Density Chamber uses industry-standard optical technology to evaluate fire safety and material hazards.
Highlights / Outstanding Features / Characteristics
- Precision Light-Obscuration Tracking: Measures smoke density by calculating the exact percentage of light blocked by smoke particles over the duration of the test.
- Quantitative Safety Data: Generates highly accurate, time-tracked data regarding smoke accumulation and visibility loss.
- Regulatory Compliance: Designed specifically to help your materials meet strict municipal, industrial, and global fire safety standards.
Description
In compliance with:
- BS EN ISO5659-2:2006 – Plastic—Smoke Generation—Part 2: Determination of Optical Density by a Single-Chamber Test
- ASTM E662-2006 – Standard Test Method for Specific Optical Density of Smoke Generated by Solid Materials
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. |
