Viscose staple fiber flame retardant performance test method
Oxygen index
1 Scope
This standard specifies the viscose staple fiber flame retardant performance test method --- oxygen index.
This method is applicable to the determination of oxygen index of flame retardant viscose staple fiber, the fiber length should be able to meet the requirements of spinning. Other types of short fibers
Referring to adopt.
This standard is only used to determine the burning behavior of materials under laboratory conditions, product quality control, and not as a measure of actual conditions of use
Under fire risk basis, one or all of the factors when a special-purpose material can only fire for analysis. This standard does not apply to assessment
When heated, the material was high shrinkage.

3 Terms and Definitions
GB/T 3291.1 and GB/T 3291.3 and define the following terms and definitions apply to this document.
3.1
Oxygen Index (OI) oxygenindex
Under test conditions, which leads to (23 ± 2) ℃ of oxygen, nitrogen mixed gas, just to maintain the minimum oxygen concentration in the combustion of fibrous material,
Expressed in volume fraction.
Principle 4
Transparent combustion cylinder of oxygen in a sample is fixed vertically upward flow of nitrogen gas mixture, the ignition top specimen, and the specimen was observed
Combustion characteristics, the continuous burning time or the length of the combustion of the sample is compared with the criterion given by different oxygen concentrations in the test series
Inspection, estimate the minimum oxygen concentration.
Test specimens of 40% to 60% have more than a predetermined length of continuous combustion time or combustion.
