Summary This standard specifies the polyester staple fiber (including hollow fiber) and polyester filament flame retardancy test methods oxygen index. This standard applies to polyester staple fibers (including hollow fiber) and polyester filament flame retardant properties of oxygen index determination. This standard only under laboratory conditions for the determination of burning behavior of materials, quality control, and not as a measure of actual use conditions, the basis for the risk of fire or only certain special purpose material for analysis when the fire of all the factors. This standard does not apply to high shrinkage rate was assessed after heating of the material.

1 Scope

This standard specifies the polyester staple fiber (including hollow fiber) and polyester filament --- Test method for flame retardancy oxygen index. This standard applies to polyester staple fiber (including hollow fiber) and polyester filament yarn measuring oxygen index. 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, 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 burning Combustion characteristics, combustion of the sample length is compared with a given criterion, by different oxygen concentrations in a series of tests to estimate the minimum oxygen concentration. Test specimens of 40% to 60% have more than a predetermined length of the combustion. 5. Apparatus 5.1 Oxygen Index 5.1.1 Oxygen Index Oxygen Index shown in Figure 1. The same effect of the instrument can also be used.
