The China Building Materials Inspection and Certification Group Co., Ltd. has made a significant contribution to the global standardization of advanced ceramic materials by leading the development of the international standard ISO 17095:2013. This standard, titled "Fine Ceramics (High Performance Ceramics, High-Tech Ceramics) – Test Method for Interfacial Bond Strength of Ceramic Materials at Elevated Temperatures," was officially released by the International Organization for Standardization (ISO). It marks an important milestone in China's growing influence in setting global technical benchmarks.
This new standard follows the release of ISO 13124:2011, another key standard in the field of fine ceramics, which was also led by the same team under the guidance of Professor Bao Yiwang, Chief Scientist of CTC. Both standards represent China’s increasing role in shaping international technical regulations, particularly in the building materials industry. These standards are based on independently developed technologies with intellectual property rights, showcasing China's technological advancement and innovation capabilities.
The implementation of ISO 17095 is crucial for addressing challenges in high-temperature interface evaluation of ceramic materials. It fills critical gaps in the testing methodology, offering a reliable way to assess the bond strength between different ceramic components under extreme conditions. This is especially important for applications in aerospace, industrial manufacturing, and construction engineering, where material performance under high temperatures is essential.
A notable feature of this standard is the introduction of the cross method, which allows for accurate evaluation of interfacial tensile and shear strength at both room and high temperatures. This method provides a more comprehensive understanding of bonding properties, enabling better design optimization and application efficiency for engineers working with brittle materials like ceramic glass.
The technology behind these standards not only enhances research and development but also offers a faster and more convenient approach for testing services. By improving the accuracy of material evaluation, it supports the enhancement of technological innovation and market competitiveness among production enterprises.
Developing an international standard is a complex and time-consuming process, typically taking at least two years from the initial proposal to final approval. The process involves several stages, including the proposal phase, preparation, technical committee review, inquiry, approval, and publication. Each stage requires extensive collaboration, discussion, and consensus among member states and technical committees.
For a standard to be approved, it must gain support from at least 189 countries and numerous industrial organizations. This reflects the rigorous nature of the standardization process and highlights the importance of global cooperation. Once approved, the standard continues to be maintained and updated over the next few years to ensure its relevance and effectiveness.
In summary, the development of ISO 17095 represents not just a technical achievement but also a demonstration of China’s growing influence in global standardization. It underscores the importance of innovation, intellectual property, and market-driven development in shaping the future of advanced materials.
