Tea set sets need to be tested according to China's GB4806, which is the general safety requirement for food contact materials and products in China's national food safety standards. This standard applies to various materials and products in contact with food, such as food packaging, tableware, kitchenware, etc. If the tea set has direct contact with food, such as tea cups, teapots, etc., then GB 4806 testing is required to ensure that it meets food safety requirements.
Tea set China GB4806 food contact materials testing items:
1. Evaporation residues in different food simulation liquids: This is to detect whether the soluble substances in the tea set material will exceed the safety limit in the simulated food environment.
2. Potassium permanganate consumption: This project is used to evaluate the oxidizability of materials under specific conditions to determine whether they may release harmful substances.
3. Heavy metals (measured as lead): Check whether the tea set materials contain excessive heavy metals, especially lead, because heavy metals may cause harm to human health.
4. Decolorization test: By simulating actual use conditions, check whether color migration occurs when the tea set comes into contact with food, thereby affecting food safety.
5. Heavy metal dissolution test: In addition to lead, the dissolution amount of other heavy metals such as cadmium, arsenic, sharp, nickel, etc. will also be tested to ensure that the tea set will not release too many heavy metals when used.
6. Toxic and harmful monomer residues: Check whether the tea set materials contain toxic and harmful monomer residues, such as vinyl chloride monomer, acrylonitrile monomer, etc.
7. Microbial testing: Evaluate whether the tea set is contaminated by microorganisms during the production and storage process to ensure its hygienic safety.
