The testing method for Chinese GB6675 food contact materials for tableware, GB 6675-2019 is the national standard "Toy Safety", and the current version is GB 6675-2014. Chinese GB6675 food contact materials are related to Chinese food regulations. It sets safety standards for plastic materials used in the manufacturing of food and baby bottles. This standard includes various regulations, such as standards for the chemical properties, soluble substances, and cleanliness of plastic materials. In addition, Chinese GB6675 also specifies the labeling and certification standards for all food contact materials, including those that require review and certification by relevant departments.

The testing items for food contact materials in China GB6675 mainly include the following categories:

1. Sensory testing: This type of testing mainly includes soaking solution testing, etc., to evaluate the sensory performance of materials.

2. Physical and chemical testing: This section mainly includes total migration testing, potassium permanganate consumption testing, heavy metal testing, decolorization testing, etc. to evaluate the chemical properties of the material.

3. Specific migration detection: This section mainly detects the migration of some heavy metals, such as lead (Pb), cadmium (Cd), chromium (Cr), nickel (Ni), arsenic (As), antimony (Sb), zinc (Zn), etc.

4. Comprehensive migration testing: This section mainly tests the migration of some harmful substances, such as formaldehyde, phenol, aromatic amines, vinyl chloride, vinylidene chloride, styrene, acrylonitrile, caprolactam, bisphenol A, plasticizers, etc.

5. Toxic and harmful substance detection: This section mainly detects the content of heavy metals such as lead (Pb), cadmium (Cd), chromium (Cr), mercury (Hg), as well as the content of harmful substances such as polybrominated biphenyls and polybrominated biphenyl ethers.

6. Microbial testing: This section mainly includes testing for total bacterial count, coliform, mold, pathogenic bacteria, etc., to evaluate the hygiene status of the materials.

In the actual testing and inspection process, the required testing items should be determined based on the testing needs and the characteristics of the product materials.
