GB/T 12416-2025 in English

This standard outlines the procedures for determining the water resistance of glass particles at 121℃, along with a classification system for evaluating their performance under such conditions. It provides a standardized approach to testing, ensuring consistent methodologies across different laboratories and applications. The document specifies the equipment, materials, and conditions required for conducting the tests, as well as the criteria for classifying the results. The testing process involves subjecting the glass particles to controlled water exposure and assessing their structural integrity and performance. This standard is intended for use by manufacturers, researchers, and regulatory bodies to ensure the quality and reliability of glass products in various environments.
