Scope

This standard specifies the test methods for determining the minimum oxygen concentration (also known as limiting oxygen index) required to maintain the burning of the specimen in the mixed flow of oxygen and nitrogen when the specimen is vertical.
This standard applies to the determination of burning behavior of various types of textiles (including single-component or multi-component), such as woven fabrics, knitted fabrics, non-woven fabrics, coated fabrics, laminated fabrics, composite fabrics, carpets (including flame retardant treated and untreated).
This standard is only used to determine the burning behavior of textiles under laboratory conditions and to control the quality of the products. It cannot be used as a basis for assessing the risk of fire under actual conditions of use, or it can only be used to analyze one of the factors when a special purpose material catches fire.

Summary	This standard specifies the sample placed in a vertical test conditions, the oxygen and nitrogen mixed gas stream, Test Method for Determining the minimum oxygen concentration required for combustion (also known as the limiting oxygen index) of the sample just to maintain. This standard applies to the determination of all types of textile products (including single or multi-component), such as woven fabrics, knitted fabrics, non-woven fabrics, coated fabrics, laminated fabrics, composite fabric, carpets, etc. (including flame retardant treated and untreated) combustion performance. The only criteria for the determination of combustion performance under laboratory conditions textiles, product quality control, and can not assess the actual conditions of use as the next fire risk basis. Or only one of all the factors of a special-purpose materials fire for analysis.
