     The national standardization of plastic products and plastic products technical committee and China CPPIA fluoroplastics processing Specialized Committee in November 2016 24-25 in Beijing innostar Hotel held a < PTFE sheet > and < polyvinylidene fluoride (PVDF) sheet > industry standard expert review. The national plastic products quality supervision and inspection center, Beijing Plastics Research Institute and Zhejiang JIAR fluorine Plastic Co., Ltd. 15 units attended the meeting. The meeting by the national standardization of plastic products and plastic products sub Technical Committee of the Secretary General Peng Yongjie presided.
    The experts listened to the standard preparation group represents the introduction of standard drafting, carefully review the submitted draft standard, preparation instructions, test report and opinion summary table and other materials. The meeting fully affirmed the standard preparation, standard preparation team collected a comprehensive, validated test work, a large number of reliable data. The materials are complete, the drafting process meets the requirements.
     The meeting that the revised standard compilation principles and main contents for the basis of advanced technology, reasonable and feasible; the main project verification and data can guide the revised standard; standard and the current laws, regulations and mandatory standards without conflict and coordination; no significant differences in the process of revision of the standard. The meeting that the standard content conforms to the actual development of the industry that can solve the development of the industry products may not bid, the standard Publicizing measures and suggestions to meet the industry requirements.
     PTFE modified standard classification of products, increase the PTFE regeneration plate resin production requirements, improve the tensile strength, tensile strain and electrical strength index, modified test method for tensile properties and electrical strength, increase the index and test method for dimensional change rate, increase the sampling plan and type test requirements.
    < polyvinylidene fluoride (PVDF) sheet > standard is to establish a standard, standard applies to homopolymer polyvinylidene fluoride material by extrusion or molding the unfilled unreinforced material. Standard tensile yield stress, nominal fracture strain, tensile modulus, impact strength and longitudinal support Jane the heat shrinkage of physical and mechanical performance requirements.
    The day before, the standard group has according to the expert review comments made further modifications to the standard, the formation of the manuscript submitted to the standardization of plastic products and plastic products technical committee, 2 will be held standard review meetings in December 19, 2016.
