Foreword

This standard replaces GB 12671-1990 "polystyrene (PS) resin." The main difference compared with the standard GB 12671-1990 are as follows. --- Chapter 2, "Normative references", in addition to hygiene standards and standard plastic resin outer sampling methods were replaced dated references file. --- Increased Chapter 3, "Classification and Nomenclature." --- Increase the Chapter 4, "General requirements." --- In 5.1, delete the original standard "size of the particles in any direction should be (2 ~ 5) mm" requirements. --- Chapter 5, "Requirements", with "the appearance of the particles" instead of the original standard of "cleanliness", with "Charpy impact strength" to replace the original standards The "Izod impact strength." Delete the original standard "flexural modulus" increased "Tensile Stress", "load deformation temperature Degree "and other projects. --- Chapter 9 polystyrene resin increases shelf life requirements. --- Added Appendix A "national standard polystyrene resin product trade name and corporate name table." Appendix A of this standard is the data appendix. The standard proposed by China Petroleum and Chemical Corporation. This standard by the National Standardization Technical Committee plastic plastic resins and petrochemical products Club (SAC/TC15/SC1) centralized. This standard was drafted. China Petroleum and Chemical Corporation Beijing Yanshan Company chemical plant. The participating units Standard. China Petroleum and Chemical Corporation Guangzhou Branch, Shanghai Secco Petrochemical Company Limited. The main drafters of this standard. Cuiguang Hong, Su Xiaoyan. This standard was first released in 1990, this is the first revision. Polystyrene (PS) resin
