3. Submit application: You need to collect product samples and related documents of the juicer and submit them to the certification agency for testing.
4. Testing and auditing: The certification body’s authorized laboratory will conduct comprehensive testing and auditing of your juicer to ensure that it meets the requirements of LFGB regulations. These tests may include material testing, sensory evaluation, microbiological testing, etc.
5. Reports and Certificates: Once the testing and audit are completed, the certification body will provide you with a detailed report stating whether your juicer meets the LFGB standards. If the product meets the standards, the certification body will issue the corresponding LFGB certification certificate.
6. Use of logo: After obtaining LFGB certification, you can use the certification logo on your juicer to show that your product has passed LFGB certification.
7. Payment and delivery: After receiving the certificate, you need to pay the relevant fees, and the certification agency will deliver the certificate to you within a reasonable time.
