220V 50hz Limited Oxygen Index Tester Burning Materials Performance Test Available GB2406
Limited Oxygen Index Test Instrument
The Limited Oxygen Index Test Instrument is designed to determine the minimum oxygen concentration required for polymer combustion. This instrument features simple operation and digital display of results, eliminating the need for manual calculations.
Standards Compliance
Meets the manufacturing conditions stipulated by national standard GB2406.
Applications
Ideal for testing the burning performance of plastics, rubber, foam, and other materials. Essential equipment for research and production of flame retardant materials, providing accurate results with excellent reproducibility.
Oxygen Index Definition
The oxygen index represents the minimum oxygen concentration (volume percentage) required for material combustion in an oxygen-nitrogen mixed gas stream under specified conditions.
Classification Guidelines:
- Oxygen Index < 22: Flammable material
- Oxygen Index 22-27: Combustible material
- Oxygen Index > 27: Flame retardant material
