Foreword

This standard is identical with ISO 6925. 1982 "textile floor coverings combustion performance tablets at room temperature test" (English Version). The relative standard ISO 6925. 1982 is mainly made the following editorial changes. --- Based on classification of carpet naming standard, the standard name in the "textile floor coverings" to "carpet"; --- Delete ISO 6925. 1982 Foreword; --- Increasing the preface of this standard; --- As a decimal point "," to the decimal point. "." This standard is GB/T 11049-1989 "textile floor coverings combustion performance test of tablets at room temperature," the amendment. versus GB/T 11049-1989 main changes are as follows. --- Increasing the normative references; --- The results are shown in the "Test results are the average of eight samples and maximum representation" with the words expressed by international standards, "the test results Each sample should represent the maximum length of the damage. " The standard proposed by China National Light Industry Council. This standard by the National Standardization Technical Committee carpet. This standard was drafted. China Arts and Crafts Association of Professional Committee of carpets, rugs, Institute of Tianjin, Weihai Carpet Group has Ltd., Weihai carpet Limited. The main drafters of this standard. Wu Shuwen, Guisheng, Ma Zhijun, Bo. This standard replaces the standards previously issued as follows. --- GB/T 11049-1989. GB/T 11049-2008/ISO 6925. 1982 Test methods for properties at room temperature tablets carpet burn

1 Scope

This standard specifies the carpet under controlled laboratory conditions, in a horizontal position exposed to the surface of the burning behavior of a small fire source. This standard applies to all kinds of organizational structures and components of carpet fibers. This standard specifies the sample is in a horizontal position, the test results do not apply to the combustion performance of carpet used in other locations. This method is used only under controlled laboratory conditions, carpet material or combination of system response to heat and flame performance evaluation, rather than using In carpet under actual fire conditions flammability rating or regulations. In trade, in accordance with ISO 2859 sampling program of sampling, this The method can serve as a satisfactory means test in commodity acceptance testing is widely used.
