A specimen of the textile and the test control fabric are exposed simultaneously to oxides of nitrogen from burnt gas fumes until the control shows a change in color corresponding to that of the standard of fading. The change in color of the specimen is assessed with the standard gray scale for assessing change in color.
Includes testing chamber, burning and control chamber, rotating sample rack, standardised gas burner, test duration timer and exhaust port (to be connected to extractor system). Temperature can be set digitally on the touch panel, and controlled automatically by the closed-loop PLC system.
The unique design of gas fume chamber ensures safety of operate and the chamber, automatic ignition at the start or, if the burner distinguished during the test, maybe in the midnight; gas leakage detection device ensures the igniter will not be activated if gas detected, the fan on the top will start to ensure the safe of operation.
