Stone is one of the most commonly used materials in home decoration, yet many consumers remain unaware of product grades, quality standards, and national regulations. To address this gap, experts from the Home Market Chamber will provide detailed explanations on different types of stone, their grading systems, and testing procedures to help consumers make informed choices.
When it comes to identifying the grade of a stone product and checking its radioactivity, Yang Xinli, Director of the Tianjin Home Market Chamber of Commerce, emphasizes that while visual inspection alone isn’t sufficient, understanding the radioactive levels is crucial. Radioactivity cannot be detected by the naked eye, so the most reliable method is to request a radioactivity report from the seller. This report ensures transparency and helps buyers avoid potentially harmful products.
Unlike other building materials, the radioactivity of stone is categorized into three classes: A, B, and C. According to the national standard GB6566-2001, "Limitation of Radionuclide Content in Building Materials," Class A materials are safe for use in all interior areas, such as countertops, window sills, and flooring. Class B materials are restricted to non-residential buildings, while Class C materials are only suitable for exterior use. This classification helps ensure the safety of both residential and public spaces.
Cao Liyun, Secretary General of the Tianjin Home Market Chamber of Commerce, advises consumers to be proactive about their rights. Always ask the seller for a radioactivity report, and pay close attention to the final conclusion—ideally, it should state "Class A." If there's any doubt, consumers can send samples to an independent laboratory for further testing. Taking these steps not only protects your health but also promotes responsible purchasing practices in the construction industry.
