Measurement Window and Candle Testing Protocol

This video is about a measurement window and candle testing protocol designed by Smokeless Chimney.
In the video, a measurement window is defined as the path that light takes through the media being measured. In this case, the measurement window is 6 mm in diameter and 150 mm long. The experiment uses a soda straw that has a similar shape and volume to the measurement window.
The video then details a draft protocol for candle testing. The protocol involves collecting baseline information for 5 minutes, lighting the candle 1 minute before the 5 minutes are up, and then inserting the candle into the light beam area. Smoke emissions are measured during flaming and then after the candle is extinguished. The video shows the test results from one of the most sensitive sensor channels, which is the clear diode response. The data shows a clear increase in signal after the candle is inserted and extinguished, indicating smoke emissions. The video also shows the incident light in Lux, which is another sensor important for opacity reading. The data for this sensor is very similar to the clear diode data. Overall, the video concludes that the draft protocol for candle testing is successful in measuring smoke emissions.
