According to a notice from Dr. Sakagnehi, Secretary-General of the Japanese Secretariat of ISO/TC 206, the international standard ISO 18558 "Fine ceramics (advanced ceramics, advanced technical ceramics) — Test method for elastic modulus and strength of ceramic tubes or rings," mainly drafted and promoted by CTC, was officially published at ISO headquarters on May 11, 2015. This is the third new international standard successfully published following ISO 13124, the first international standard in China's building materials industry transformed from independent intellectual property technology, and was completed by the team led by Bao Yiwang.

The project was officially approved in ISO/TC 206 in June 2012. The project lasted more than three years and went through multiple stages including NP, WD, CD, DIS, and FDIS. Through multiple international meeting discussions, a large number of opinions from international industry experts and competitors were received. Through analysis, calculation, and experimental verification of these opinions, unanimous recognition was ultimately obtained.

ISO 18558 effectively solves the technical difficulty of testing the modulus and strength of ring-shaped or tubular ceramic materials, fills a gap, and is applicable to research and application fields such as aerospace materials, special industrial materials, inorganic non-metallic building materials manufacturing, and construction engineering. It is of great significance for effectively safeguarding people's lives and property.

As a developing country, the number of international standards proposed by China and led by China is very limited, making this another milestone in the development of the industry. The successful publication of this series of international standards not only effectively enhances the high-tech content, innovation capability, and core competitiveness of CTC's testing services, promotes the better and stronger future development of CTC, and improves CTC's status among international peers, but also establishes CTC's industry image and corporate image.
