The main purpose of testing FCM (food contact material) stainless steel thermos is to ensure that these materials do not release harmful substances when in contact with food, thereby ensuring the food safety of consumers. The following are the main steps and key points of the test:
1. Determine the test standard
According to the relevant regulations of the EU and the United States, stainless steel thermos need to comply with the following standards and regulations:
- EU: Regulation 1935/2004/EC
- US: FDA's relevant standards and regulations
2. Choose the appropriate test method
For the double-layer stainless steel material of the stainless steel thermos, the possible test methods include:
- Chemical composition analysis: Detect whether the raw materials of the thermos contain banned harmful chemical ingredients.
- Migration test: Evaluate whether the chemical components in the surface coating or material of the thermos will migrate into the food when it comes into contact with food.
- Toxicity assessment: Toxicity assessment of the chemical components detected in the migration test to determine whether they will cause harm to human health.
3. Prepare samples
Prepare a sufficient number of samples that meet the requirements according to the requirements of the test method. Make sure the sample is not treated in any way to reflect the true condition of the product.
4. Submit a test application
Submit the sample and test application to an approved testing agency. The application should include detailed information about the product, the purpose of the test, the applicable standards, etc.
5. Conduct the test
The testing agency will test the sample based on the submitted test application and the applicable standards. This includes but is not limited to:
- Chemical analysis: focus on whether the raw materials and coatings of the thermos contain harmful chemical components.
- Physical property testing: evaluate the thermal insulation performance, compressive strength and other physical properties of the thermos.
- Toxicological evaluation: evaluate the toxicity of the chemical components detected in the migration test.
6. Obtain a test report
The testing agency will issue a detailed test report stating the test results of the sample and whether it complies with relevant standards and regulations.
7. Compliance determination
Based on the results of the test report, determine whether the thermos complies with the safety standards for food contact materials.
8. Labeling and instructions
Ensure that the stainless steel thermos is clearly labeled with material type, usage precautions, cleaning instructions, etc. to help consumers use and maintain the product correctly.
9. Continuous monitoring
Even if the product has passed the test, quality monitoring should be carried out regularly to ensure that the product continues to meet safety standards during the production process.
Through the above steps, it can be ensured that the stainless steel thermos will not release harmful substances when in contact with food, thereby ensuring the food safety of consumers.
