Evaluate the Quality of Products; 2. Determine the product quality level、 i.e. the severity of defects; 3. Inspect the process flow and supervise the process quality; 4. Collect、 statistics、 and analyze quality data to lay the foundation for quality improvement and management activities; 5. Introduce arbitration inspection to determine the responsibility for quality accidents. The purpose of handling third-party testing reports is to obtain an independent、 objective、 and professional evaluation result to confirm whether the tested items or services comply with relevant regulatory standards、 quality requirements、 or technical specifications、 and to verify their safety、 reliability、 and performance. Third party testing reports are typically used in areas such as product certification、 market access、 supply chain management、 trade negotiations、 and dispute resolution. Precautions for Testing Report: Carefully read and understand each section after receiving the testing report. Ensure that there is a "research and testing special seal" and official seal in the report、 and check the anti-counterfeiting QR code to confirm its effectiveness. Confirmation information: Verify whether personal or organizational information is accurate and accurate. If the report is not stamped with the "Research and Testing Special Seal" or official seal、 it is invalid. Pay attention to the test results: Focus on the summary and detailed information of the test results. If in doubt、 consult relevant engineers and it is strictly prohibited to alter the report. Pay attention to the reference range: Check the reference range of the test results to see if the results are normal. As the reference range varies depending on factors such as samples、 test methods、 reference standards、 etc.、 please contact our engineers to discuss your specific situation. Objection handling: If you have any objections to the test report、 please file an appeal within 15 days of receiving the report. Late appeals will not be accepted.
