As a material that may come into contact with food, polyurethane mesh glue does need to consider whether it meets relevant safety standards during the production and sales process. China GB4806 is a national standard for food contact materials and products. It stipulates the basic requirements, limits and testing methods for food contact materials and products to ensure that these materials and products will not cause food contamination and thus protect the health of consumers.
Polyurethane mesh glue is tested according to GB4806 in China to ensure that it meets the safety standards for food contact materials. The testing process usually includes the following steps:
1. Submit application and prepare samples:
Applicants need to submit a GB4806 testing application to the testing agency and provide relevant product information, such as product name, use, specifications, etc.
Prepare polyurethane mesh samples that meet the requirements to ensure that the samples represent the actual products produced and are sufficient for various tests.
2. Sample reception and registration:
The testing agency receives the samples, registers them, and confirms that the sample information is consistent with the application information.
Number and identify samples to ensure traceability during the testing process.
3. Pretreatment and sample preparation:
According to the requirements of the GB4806 standard, necessary pre-treatment, such as cleaning, drying, etc., is performed on the polyurethane mesh samples.
Prepare samples that meet the testing requirements for subsequent testing.
4. Test project execution:
According to the requirements of the GB4806 standard, corresponding testing items are implemented, including physical performance testing, chemical performance testing, migration testing, etc.
Use professional instruments and testing methods to detect and analyze polyurethane mesh samples.
5. Data recording and organization:
During the testing process, each testing data is recorded in detail to ensure the accuracy and completeness of the data.
Organize and analyze the test data and form a test report.
6. Report preparation and review:
The testing agency prepares a testing report based on the testing data and describes the testing status, results and conclusions of the sample in detail.
After the report is internally reviewed and signed for confirmation, it is delivered to the applicant.
7. Certificate issuance (if applicable):
If the polyurethane mesh sample meets the requirements of the GB4806 standard, the testing agency will issue a corresponding certificate of compliance.
