This standard specifies the analytical method for the hygienic standard of polytetrafluoroethylene coatings on the inner wall of food containers. This standard is applicable to polytetrafluoroethylene coatings composed of polytetrafluoroethylene as the main raw material and certain additives, which are applied to metal surfaces such as aluminum and iron plates and sintered at high temperatures as anti-stick coatings that come into contact with non-acidic food containers. The use temperature is limited to below 250°C.

3.1 Preparation of test specimens
Use 2mmx10mmxamm or glass plate bottom village or paint according to the actual construction process. One half of them is for test and the other half is for two months for each arbitration analysis. 3.2 Sample treatment
Clean the test rod with detergent, rinse with tap water, then rinse with water for two months, prepare for two months, and place it in the room for 21 months under the soaking condition of 3.5: 3.5.
1% acetic acid: boil at 0.55°C. Place at room temperature for 24h. Correction: add 1% mJ per square meter of contact area. If the test container is a container, add 2/3-4/5 of the foaming liquid to produce volume. 4 Sensory indexes
Measure the surface of the coating and the surface of the coating with oral test results
5 Evaporation residue inspection
Analyze according to the determination method of thermal residual treatment specified in (B/T009.602223), 6 High short acid hair loss
