EN 50399 Cable Flame Spread / Heat Release And Smoke Test Equipment

Specific parameters are as follows:

1. Light source: imported German incandescent lamp
2. Nominal power: 10W
3. Nominal voltage: 6V
4. Accuracy: ±0.01V
5. Receiver: For the Hamamatsu Silicon Photovoltaic Cell of Japan, the signal is amplified by the board and input to the computer through the I/O board. The spectral response is matched with the photometer of the International Commissioner of Light (CIE).
6. Laser system: The laser photometer should use a helium-neon laser with an output power of 0.5 mW to 2.0 mW. Air should be introduced into the tube, and the optics should maintain the cleanliness (F.4.2) that meets the requirements for light attenuation drift. Compressed air can be used instead of self-inhaled air.

3. Analytical instrument pre-treatment: Before the analysis of the oxygen and carbon dioxide content of the flue gas generated during the test, pre-treatment is carried out to ensure the flue gas is dry and the particle concentration level required by the analytical instrument is reached. The pre-treatment consists of condensation, filters, German KNF sampling pumps, flow meters and piping.
