Foreword

This standard was drafted in accordance with GB/T 1.1-2009 given rules. The standard proposed by China Textile Industry Association. This standard by the Shanghai textile industry technical supervision of the centralized. This standard was drafted. Shandong Helon Co., Ltd., Shanghai textile industry technical supervision, Tangshan Sanyou Xingda Chemical Fiber Group has Limited. The main drafters of this standard. Xing Chunhua, the Good Lou, Lu Xiuqin, Zhou Zhen De, Li Jianghua, engravers. 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.
