Foreword

This standard was drafted in accordance with GB/T 1.1-2009 given rules. This standard uses redrafted law revision using ISO 8974.2002 Determination of free phenol containing "plastic phenolic resin by gas chromatography the amount". This standard and ISO 8974.2002 technical differences and their reasons are as follows. --- Chapter 1 "Scope" Add "This standard applies to phenolic resin of free phenol content determination" to increase the standard of the applicable limit, Fu Write requirements set standards; --- Increasing the internal standard mass m 'in the formula, the international standard was originally written in the "quality of the internal standard to calculate the concentration of the liquid storage and To "in order to more clearly increases the concentration is calculated from the conversion quality; --- Chapter 9 of the precision in Appendix C, said chapter accordingly explanation for failing to obtain laboratory data, it will be international Standard precision choreography in an appendix. This standard also made the following editorial changes. --- Change the standard name is "the determination of free phenol content of phenolic resin by gas chromatography", in line with existing standards; --- Chapter 2, "Normative references", according to GB/T 1.1-2009 requirements, adjust normative language reference guide. The standard proposed by China Petroleum and Chemical Industry Association. This standard by the National Standardization Technical Committee plastic thermosetting plastics Club (SAC/TC15/SC11) centralized. This standard is drafted by. Shandong Shengquan Chemical Corporation. Participated in the drafting of this standard. Country synthetic resin Quality Supervision and Inspection Center, Shanghai European-Asian Synthetic Material Co., Ltd, Changshu Southeast Plastic Expected Ltd. Shaxian Hongsheng Plastic Co., Ltd., Wuxi Chong Electronics Co., Ltd. The main drafters of this standard.
