The determination of oxygen index instrument:
JF-3 oxygen index tester meets plastics test method for the oxygen index method and GB/T2406textile national standard test oxygen performance index method GB/T5454 standard forcombustion, combustion performance under stipulated test condition evaluation of polymers,namely the determination of polymer just to maintain the oxygen volume percentage concentration of combustion. Determination of combustion performance is suitable for plastic,rubber, fiber, foam, film, film and textile and wood materials such as.
The oxygen index measuring instrument is a kind of determination of polymer burning accurate,reproducible detection instrument is good, convenient and quick. The instrument of determination of simple operation using digital instrument, not only can be used as identification of polymer flame retardant means, but also can be used as a research tool.
