The Annual Meeting of the Non-metallic Sealing Working Group and the Standards Seminar were held in Xianyang, Shaanxi.

The Non-metallic Sealing Working Group Annual Meeting and Standards Seminar, hosted by Xianyang Non-metallic Mineral Research and Design Institute Co., Ltd., the National Non-metallic Mineral Products Quality Supervision and Inspection Center, and the National Non-metallic Mineral Products and Products Standardization Technical Committee, and co-organized by Chengdu Junma Sealing Technology Co., Ltd., was held on January 11, 2019, in Xianyang City, Shaanxi Province. All members of the Non-metallic Sealing Working Group and representatives from relevant production enterprises and users nationwide attended the meeting. The meeting successfully completed all scheduled agendas and concluded satisfactorily.

The meeting was jointly chaired by Wu Yimin, head of the Non-metallic Sealing Materials Group, Vice Chairman and Chief Engineer of Zhejiang Guotai Xiaoxing Sealing Materials Co., Ltd., and Shi Zhigang, Executive Deputy Director of the National Non-metallic Mineral Products Quality Supervision and Inspection Center.

First, Lei Jianbin, Executive Director and Party Secretary of Xianyang Non-metallic Mineral Research and Design Institute Co., Ltd., and Secretary-General of the National Non-metallic Mineral Standardization Committee, delivered a welcome speech, warmly welcoming production enterprises and expert representatives from across the country. He emphasized that the standards discussed at this meeting should be based on practical needs, that the revision of standards should promote industry development, and that standards should play a leading role in guiding industry progress. He also wished the meeting a complete success.

Hou Libing, Secretary-General of the Non-metallic Sealing Working Group, presented the "2018 Work Report of the Non-metallic Sealing Working Group," pointing out that the working group established in 2018 laid the foundation for the future establishment of a sub-technical committee for non-metallic sealing materials. The meeting achieved the expected results.

Post-meeting work of the working group includes standard defense, standard formulation and revision, and translation of standards into foreign languages. The status of the standard system construction was explained. Finally, the 2019 work plan of the working group will focus on applying for related standard projects under the standards "Made in China 2025" and the "New Materials Standards Leading Plan," and completing the existing planned national and industry standards on schedule with quality assurance. In 2019, the group will continue to provide service support, actively assist associations and alliances in formulating and reviewing group standards, and help new product manufacturers develop enterprise standards.

The meeting also discussed two building materials industry standards: "Roller-pressed Asbestos-free Fiber Gasket Materials" and "Non-metallic Sealing Packing," as well as four national standards: "Classification System and Test Methods for Non-metallic Gasket Materials Part 1: Classification System for Non-metallic Gasket Materials," "Classification System and Test Methods for Non-metallic Gasket Materials Part 3: Test Methods for Chemical Resistance of Gasket Materials," "Classification System and Test Methods for Non-metallic Gasket Materials Part 5: Test Methods for Creep Relaxation Rate of Gasket Materials," and "Classification System and Test Methods for Non-metallic Gasket Materials Part 6: Test Methods for Adhesion of Gasket Materials to Metal Surfaces." Representatives spoke freely and expressed their views, reaching a basic consensus on major content involved in the standards, such as the scope of each standard, normative references, technical requirements, and inspection methods.
