Ceramic tableware in China needs to follow the testing standards of GB4806.4-2016 "National Food Safety Standard for Ceramic Products". This standard specifies the safety requirements for ceramic products used in food contact, including migration limits for lead and cadmium. Specific testing content includes:
1. Sensory requirements: The product should not have defects such as glaze explosion, bumps, cracks, and leaks. The color should be uniform, the surface should be smooth, and the pattern should be complete without color difference or deformation.
2. Lead migration amount detection: Use 4% acetic acid solution as the food simulation liquid, soak according to the time and temperature conditions specified in the standard, and then test the lead migration amount to ensure that it does not exceed the limit specified in the standard.
3. Cadmium migration amount detection: Also use 4% acetic acid solution for immersion to test the cadmium migration amount to ensure its safety.
4. Other physical and chemical indicators: may include potassium permanganate consumption, heavy metal content, etc.
5. Label identification: The product should provide clear identification information, including product name, material, name, address and contact information of the manufacturer and distributor, production date, etc.
Manufacturing enterprises should select qualified raw materials, strictly control the production process, conduct product testing, and label products to ensure that the products meet the requirements of the GB 4806.4-2016 standard. When purchasing, consumers should give priority to products that meet this standard and avoid using inferior or non-existent products to ensure food safety and health.
