BACKStandards:
ASTM D 2863, ISO 4589-2, NES 714 GB/T 5454 GB/T 10707 GB/T 8924-2005 GB/T 16581-1996 N B/SH/T 0815-2010 TB/T 2919-1998 IEC 61144-1992 ISO 15705-2002 ISO 4589-2-1996
Applications:
Suitable for the determination of combustion properties of plastics, rubber, fiber, foam, film and film and textile materials, measuring the minimum oxygen concentration that will support combustion. The test specimens are burned in a precisely controlled atmosphere of nitrogen and oxygen .
Product Information:
The Oxygen Index is, perhaps, the most economical and precise quality control test of combustible materials. Its ease of use together with high levels of precision has made this technique a primary characterising and quality control tool to the plastic and electric cable industries and it has been specified by several military and transport groups. The technique measures the minimum percentage of oxygen in the test atmosphere that is required to marginally support combustion. Note that BS ISO 4589 supersedes BS 2782 Part 141.
