The qualification standards for silicone kitchenware are mainly based on GB 4806.1-2016 "Food Contact Materials Part 1: General Requirements", which provides detailed specifications for the definition, requirements, testing methods, etc. of silicone materials. Specifically, the qualification standards for silicone materials include the following:
1. Safety requirements: Silicone materials must not contain harmful substances.
2. Physical requirements: silica gel material shall have the characteristics of using machinery, physics, kinematics, wear, aging resistance, etc.
3. Thermal stability: Silicone materials should have thermal stability that meets application requirements and can maintain the characteristics and stability of the material under elevated temperature conditions.
4. Soakability: Silicone materials should have soakability that meets application requirements, can directly come into contact with food without causing adverse reactions.
5. Production process requirements: The production process of silicone materials must comply with safety production, environmental protection, hygiene and other requirements.
In addition, silicone materials are required to pass the following tests in the GB 4806.1-2016 standard to ensure their safety:
- Physical performance testing: The tensile strength, elongation, hardness, density, and other physical properties of silicone materials need to be tested to ensure their strength and stability.
- Migration testing: Contact silicone material with simulated food,? Measure the substances that migrate from food contact materials under certain time and temperature conditions.
- Light intensity accelerated aging test: Conduct a certain period of light intensity accelerated aging test on silicone materials to evaluate the performance changes of the material under long-term use and storage conditions.
When consumers choose silicone kitchenware, they should pay attention to the food grade environmental certification test report provided by the manufacturer, or the FDA and? LFGB certification testing report to ensure that the purchased silicone kitchenware is safe and reliable.
