The plastic smoke density tester/FTT smoke density chamber can be used to measure and describe the response of materials, products, and components to heat and flame under controlled laboratory conditions, and to measure the static smoke production of building materials under combustion or decomposition conditions.
The touch screen computer dual control smoke density tester for building materials is developed according to the technical conditions specified in the national standard GB / T8627-2007 "test method for smoke density of burning or decomposition of building materials". It is suitable for the determination of static smoke yield of building materials and their products and other materials
Design standard: GB / T8627-2007 test method for smoke density of combustion or decomposition of building materials
Standard:
GB / T8627: Test method for density of smoke from the burning or decomposition of building materials
ASTM D2843: Standard Test Method for Density of Smoke from the Burning or Decomposition of Plastics
ASTM E662: Standard Test Method for Specific Optical Density of Smoke Generated by Solid Materials
ISO 5659: Plastics — Smoke generation — Determination of optical density by a single-chamber test
1. Dual control mode, which can be controlled on the touch screen or on the computer, and the operation mode can be easily switched! (user's own computer and printer; upper computer software, router and network cable will be sent with the device)
2. A device can be operated by several computers at the same time, and several computers can be online at the same time, which can realize LAN sharing!
3. The main and auxiliary burners can rotate automatically with accurate positioning.
4. The self-developed control program can meet the requirements of various operations, records, time curves and results calculation in the test.
| Parameter | Description |
|---|---|
| Maximum smoke density (MSD) and smoke density rating (SDR) measurement | 0 - 100% continuously measurable and automatically calculated |
| Calibration error of standard filter | Not more than 3%; each equipment equipped with three standard filters for light source calibration data representation |
| Working pressure of Bunsen lamp | (210 ± 5) kPa |
| Flame application time of Bunsen lamp on sample | 4 min |
| Combustion lamp | Bunsen lamp, length 260mm, nozzle diameter 0.13mm, at a 45° angle with the smoke box |
| Photoelectric system - light source | Bulb, power 15W, working voltage 6V |
| Exhaust system | Equipped with a powerful exhaust fan to expel waste gas out of the room after the test |
| Measurement range of smoke density | 0 ~ 100% |
| Accuracy of smoke density measurement | ± 3% |
| Receiver | Silicon photocell; 0% transmittance means no light passing through, 100% transmittance means complete light passing through |
