High Profermance EN ISO 4589-2 Limit Oxygen Index Test Apparatus
Application:
Under predetermined conditions, in a mixed stream of oxygen and nitrogen measured, just to maintain the minimum oxygen concentration of the sample required for combustion (also known as the oxygen index) - expressed in percent by volume. It can be used to determine the combustion performance of a variety of textiles, including woven, knitted and non-woven fabrics, etc. Also be used to determine the burning of the plastics, rubber, paper, etc
Standards:
ASTMD2863, ISO4589, GB/T2406-93
GB/T5454-1997 :"Determination of burning behavior of textile products approved oxygen index assays"
GB/T2406.2-2009: "Plastics - Determination of burning behavior - Part 2 at room temperature Oxygen Index test method."
ISO 4589-2 :Plastics-Determination of burning behaviour by oxygen index-Part 2: Ambient-temperature test Plastics - Determination of burning behavior by oxygen index - Part 2: Test temperature
ASTM D 2863: is similar to the supply of plastic burning candle minimum oxygen concentration measuring method (oxygen index)
