Plastic Smoke Density Test Apparatus

Description: The test apparatus suitable for measuring the smoke emitted by wires and cables burning under specific conditions, such as horizontal combustion of some cables or optical cables, are used as a means of comparing different cables or optical cables or judging whether they meet specific requirements under flaming or flameless combustion conditions. . It meets the test standard of GB/T17651.1-2-19.98 "Determination of smoke density in combustion of cables and optical cables under specific conditions". Performance parameters: Optical measuring device: The light source and receiver should be placed in the middle position outside the sealing window on the opposite wall of the combustion chamber. Measurement range: 0-100%. That is, the optical device will be energized before the blank test. Calibration of transmittance: calibration with transmittance of 25%, 50% and 75%. Standard Fire Source: Standard Fire Source: 1.0L+0.01L Alcohol Plate; Ethanol: 90% +/- 1%; Methanol: 4% +/- 1%; water: 6% +/- 1%. Control system: adopt DETECION control procedure and ZWH 4500 acquisition control card. Operating interface: WINDOWSXP operating interface, DETECION control program, perfect security mechanism. During the test, the measurement results are displayed in real time and the perfect curve is plotted dynamically.
