Limiting Oxygen Index Chamber HF-2
Limiting Oxygen Index Chamber which also named Oxygen Index Apparatus or Oxygen Index Test Apparatus. Limiting Oxygen Index Chamber is used to test material flame retardant performance of the instrument, the testing materials under the experimental conditions, the oxygen and nitrogen in the mixed gas just keep sample minimum oxygen concentration needed for combustion.
Limiting Oxygen Index Chamber HF-2
Limiting Oxygen Index Chamber is suitable for determining the minimum oxygen concentration required to maintain the sample combustion in a mixture of oxygen and nitrogen under specified test conditions. It is used to evaluate the combustion performance of homogeneous solid material, laminated material, foam material, film and film, etc.
Sample fixed in the vertical upward flow of oxygen, nitrogen gas mixture in the combustion cylinder, lit the top sample, observing the combustion characteristic of sample, the sample of continuous time or sample combustion length compared with the given limit, through a series of experiments under different oxygen concentration, measured expressed as a percentage of oxygen, when burned, maintain the minimum oxygen density.
The normal temperature oxygen index tester is designed to determine the minimum oxygen concentration required to maintain the sample combustion in the oxygen and nitrogen mixture under the specified test conditions.
We provide reasonable price and high quality Limiting Oxygen Index Chamber.Follows are features of Limiting Oxygen Index Chamber

Application of Limiting Oxygen Index Chamber
Limiting Oxygen Index Chamber is used to assess the burning behavior of polymers by oxygen index (OI) under specified test conditions. That is to determine the minimum concentration of oxygen in admixture with nitrogen, which will support combustion of small vertical test specimens under specified test conditions and the results are defined as oxygen index values. It is applicable to plastic, rubber, fibre, foam-plastic, flexible sheet and film materials. With properties of high-accurate measurement, excellent performance on repeatability and convenience, it is not only used to assess the resistance of polymers to flame, but also used in researches to understand the flaming procedure of polymers better.
Limiting Oxygen Index Chamber complies with GB/T 2406, ASTM D 2863 , ISO 4589-2 etc international and retailer standards.
