Test item optical performance: Test the optical performance parameters of the film、 such as transmittance、 reflectivity、 and optical polarization effect、 to ensure that the film has good transmittance and protective effect. Anti blue light performance: Test the protective effect of the film on the blue light band (400nm-500nm) to ensure that the film can effectively reduce the damage to the eyes caused by blue light. Hand evaluation: Test the tactile and sliding properties of the film to ensure its comfort and convenience during use. Durability: Test the wear resistance、 corrosion resistance、 and high temperature resistance of the film to ensure its durability and stability during use. Safety: Test the membrane for harmful substances、 compliance with environmental requirements、 and compliance with national safety standards. Detection range Hardened film: Hardened film is a type of tempered film that has good scratch and impact resistance、 while also effectively reducing the harm of blue light to the eyes. Vacuum coating: Vacuum coating can achieve anti blue light effect by coating a layer of transparent metal material on the surface of the film. Filter film: The filter film adopts the principle of a filter lens、 which reduces the influence of blue light by selectively absorbing and reflecting light. Biobased polymer material membrane: Biobased polymer material membrane uses natural polymer materials、 which have good biocompatibility and environmental performance、 while also effectively preventing damage from blue light. Relevant reference standard specifications CEI 34-141-2014: Application of International Electrotechnical Commission 62471 to evaluate the harm of blue light to light sources and luminaires 5 GB/T 23595.1-2009: Test methods for rare earth yellow fluorescent powder for white light LED lamps Part 1: Determination of spectral performance GB/T 23595.1-2009: Test methods for rare earth yellow fluorescent powder for white light LED lamps Part 1: Determination of spectral performance GB/T 38120-2019: Technical requirements for the application of blue light protective films for light health and light safety T/CI ES 011-2019: Safety Requirements for Single ended Fluorescent Lamps T/CVIA 61-2017: Health Display Devices Part 1: Technical Requirements and Test Methods for Low Blue Light Display Devices for Mobile Terminals T/CVIA 62-2017: Health Display Devices Part 2: Technical Requirements and Test Methods for Low Blue Light Display Devices for Display Devices Purpose of Processing Test Reports 1: Evaluating 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.
