Foreword

This standard is equivalent to international standards ISO 9772.2001 (English Version) "--- small foam sample at the level of a small flame burning conditions Burning performance measurement. " The standard ISO 9772.2001 (E) mainly made the following editorial changes. --- Deleted international standards foreword; --- The 4th chapter of international standards listed in Appendix B of this standard; --- International standard precision data included in Appendix C of this standard; --- The revised International Standard ISO , the sample 9772.2001/Amd1.2003 (E) directly written standards. This standard replaces GB/T 8332-1987 "foam burning behavior of horizontal burning method." This standard and GB/T 8332-1987 compared to the main changes are as follows. --- Adopt different standards, this revision is identical with ISO 9772.2001 (E), the original standard is equivalent to ISO 3582. 1978; --- Increase the informative Appendix A, grading system; --- Increase the informative Appendix B, for a description of the test; --- Increase the informative appendix C, ISO 9772 precision. The Standard Appendix A, Appendix B, Appendix C is informative appendix. The standard proposed by China Petroleum and Chemical Industry Association. This standard by the National Standardization Technical Committee of plastic (SAC/TC15) centralized. This standard is drafted by. National Plastic Products Quality Supervision and Inspection Center (Fuzhou), the National Quality Supervision and Inspection Center of synthetic resin. Participated in the drafting of this standard. Blonde Technology Co., Ltd., Sinopec hospital north of the National Chemical Building Materials Testing Center (Materials testing Test unit), National Plastic Products Quality Supervision and Inspection Center (Beijing), Ministry of Public Security Shanghai Fire Research Institute, Nanjing Jiangning District analytical instrument factory. The main drafters of this standard. Ho Bo, Lanming Rong Cheng hydrogen, Wang Jiandong, Li Jianjun, who Dongmei, Lijie Tao, Zhang Zhengmin, Wang Fuhai.
