Oxygen Index Flammability Testing Equipment ASTM D 2863, ISO 4589-2
Introduction
Oxygen Index Flammability Testing Equipment measures minimum oxygen concentration as necessary when specimen combustion. This equipment’s the oxygen analyser is adapted Paramagnetic Type which has a precise, long life, less error rate and high reliability.
TI (Temperature Index Tester) measures temperature index of specimen by heated mixing gases on temperature up to 400℃ in the atmosphere oxygen concentration. According to ISO 4589-3, high temperature is best factor to assess combustibility of materials better than Oxygen Index.
Oxygen Index Flammability Testing Equipment lowers the height of glass chimney, gives data result from DAQ System interfaced with PC. And this has simple design and convenience such as foot switch.
This meets the contents of standards like ASTM, ISO, NES, KS and so on.
Standard
According to B/T2406.1-2008,ISO5489-1:1996, ASTM D 2863, ISO 4589-2, NES 714 . ISO 4589-3 NES 715
Scope
Used to assess the combustion performance of plastic, rubber, fiber, foam, film and film and textile materials such as polymer in experimental conditions, namely measure minimum volume of oxygen concentration of percentage for polymer just maintain burning.
