Automatic Oxygen Index Tester Introduction:

The high temperature oxygen index tester is designed and de-veloped according to ISO4589-3 (Elevated-temperature test) and British Naval Engi-neering Standard NES 715. Based on the general intelligent oxygen index instrument,the high temperature oxygen index tester adds a electric-heating device at the position of the combustion cylinder to preheat the mixed gas and test the ignition temperature of the different materials at a certain oxygen concentration. The tester is used to assess the combustion performance of a self-supporting vertical strip or a sheet-like plastic material of 10.5 mm thickness and is also applicable to the determination of the burn-ing performance of a vertically supported.


Critical Oxygen Index Test Apparatus Standards:
