1 Scope

This standard specifies the flame retardant synthetic fiber raw slice Test Method --- oxygen index. This method is suitable for polyester (PET) chips, sliced polycaprolactam and polyhexamethylene adipamide slices. Other synthetic materials sliced Reference may be used. 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 4146.1, GB/T 4146.3 and as defined in the following terms and definitions apply to this document. 3.1 Oxygen index oxygenindex; OI Under test conditions, which leads to (23 ± 2) ℃ of oxygen, nitrogen mixed gas, just to maintain the minimum oxygen concentration in the combustion of materials to body Integral numbers. 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 length of the sample is compared with a given criterion, by different oxygen concentrations at a series of tests to estimate the oxygen concentration The minimum degree. Test specimens of 40% to 60% have more than a predetermined length of continuous combustion. 5. Apparatus 5.1 Oxygen Index 5.1.1 schematic As shown in Figure 1. The same effect of the instrument can also be used.
