EN 10204 Type 3.1
Certification Protocol
Standardized inspection documents in European trade verify that delivered materials conform to purchase order specifications based on testing conducted by an independent representative. In the context of EN 10204 Type 3.1, the material manufacturer provides a certificate that contains the specific test results for the batch of substrate being supplied, such as chemical composition and mechanical strength. This is an essential document for high-performance packaging films, metal components, or specialty barrier papers used in critical food or pharmaceutical packaging.
It provides the customer with direct, audited proof of the batch’s technical performance.
Inspection Authority
Testing must be conducted on the specific batch being delivered, rather than on general product lines. To issue an EN 10204 Type 3.1 certificate, the manufacturer must use a designated inspection representative who is independent of the production department. This ensures that the test results are unbiased and have been verified by a qualified quality assurance technician.
The certificate is validated by the representative’s signature or official stamp to ensure its authenticity.
Quality Guarantee
Procurement departments require these certificates to maintain strict quality control records and trace batches. When issues arise during printing or converting, having the original test data helps technicians identify the cause of the failure. This reduces dispute resolution times between the paper mill and the converter.
