On November 1, 2016, the international standard ISO 19603 "Fine ceramics (advanced ceramics, advanced technical ceramics) — Test method for determining elastic modulus and strength of thick ceramic coatings," mainly drafted and promoted by CTC, was officially published at ISO headquarters. This is the fifth new international standard successfully published by CTC, following ISO 13124, the first international standard in China's building materials industry transformed from independent intellectual property technology, and was completed by the Central Research Institute led by Chief Scientist Bao Yiwang.

The international standard was officially approved as a project in ISO/TC 206 in November 2013. The project lasted more than three years and went through multiple stages including NP, WD, CD, DIS, and FDIS. Through multiple international meeting discussions, solicitation of comments, and experimental verification, it ultimately obtained unanimous recognition.

ISO 19603 establishes methods for determining the elastic modulus and strength of thick ceramic coatings, studies the influence of various test factors, and conducts experimental verification, filling a technical gap. It is of great significance for improving China's new product development, especially for military products and national defense construction. The related technologies of the international standard can also be applied to the evaluation of strength and elastic modulus of coated glass tubes, cement pipes, and laminated materials, with extremely broad application prospects. The successful publication of this international standard not only demonstrates CTC's innovation capability and core competitiveness as a high-tech service industry in inspection and certification, but also wins more international discourse power for the development of China's building materials testing.
