Recently, Bao Yiwang, Chief Scientist of CTC, Wan Detian, Executive Deputy President of the Central Research Institute, and Engineer Pan Ruina attended the 25th ISO/TC 206 Fine Ceramics Standardization Annual Meeting (hereinafter referred to as the Standard Annual Meeting) held in Malaysia.

Professor Bao Yiwang chaired the session of the WG8 Ceramic Bonding Working Group, introduced the working group's progress over the past year, and fully exchanged views with experts and scholars from member countries of the ISO/TC 206 Fine Ceramics International Standardization Organization on international standards at different stages and issues of mutual interest. At the same time, Professor Bao Yiwang reported at the meeting on the proposed international standards “Test Method for Thermal Conductivity of Ceramic Coatings” and “Test Method for Tensile and Shear Creep Properties of Ceramic Adhesives,” which attracted the attention of many experts.

Subsequently, Professor Wan Detian and Pan Ruina respectively reported and discussed the progress of two international standards under development, “Test Method for Determining Thermal Expansion Coefficient and Residual Stress of CVD Ceramic Coatings” (ISO WD 23458) and “Test Method for Elastic Modulus of Ceramic Materials at High and Ultra-High Temperatures” (ISO WD 21713), and revised them according to the modification opinions put forward by the working group experts. Both standards are about to advance to the CD (Committee Draft) stage.

Finally, Professor Bao Yiwang participated in the TC206 Advisory Committee meeting on behalf of China. At the meeting, issues that should be noted in the application and development of international standards in the future were discussed: 1. New international standards should have major demand and background support. 2. International standards need to be verified (multiple laboratories and institutions at home and abroad should conduct Round Robin Tests for cyclic verification and comparative testing). 3. International standards need to be communicated with experts before the vote on new project proposals to obtain support. 4. Cooperation and interaction with other TCs should be established to avoid duplicate applications.

During the meeting, project team members conducted technical exchanges with experts from Japan, South Korea, Belgium, France, and other countries on issues including ceramic coatings, interfacial bonding strength, the notched-ring method, and related mechanics. They discussed in detail the problems existing in the standards and how to improve them, continuously improving and making up for deficiencies.

Participating in the annual meeting of the ISO/TC 206 Fine Ceramics Standardization Technical Committee has become an important way for CTC to participate in international standard formulation. The project team will, as always, continue to work hard, strive to develop more international standards led by China, and further enhance the status and competitiveness of China Building Materials Academy and CTC in the field of international standard formulation and revision.

The standardization work of China's building materials industry has a long and arduous journey ahead. To promote the in-depth development of China's standardization work, enhance China's status in the international community and its discourse power in standard formulation, we must change our development thinking, emancipate our minds, base ourselves on innovation, rely on standardization organizations and social organizations, formulate and revise building materials standards that are competitive in domestic and international markets, guide the healthy development of the industry, and promote the improvement of advanced productivity in the building materials industry.
