T/GDEIA 8-2019 Vehicle glass functional film

Scope

Scope: This standard specifies the terms and definitions, classification, requirements, test methods, inspection rules, and marking for functional films used on automotive glass. This standard applies to the production and quality inspection of functional films applied to automotive glass. It does not apply to safety window films that resist external force damage, such as bulletproof and impact-resistant films, nor to externally applied automotive window films. Main technical content: This group standard specifies the main technical requirements for functional films used on automotive glass, including appearance quality, thickness deviation, dimming amplitude and visible light transmittance, semi-recovery time, visible light reflection ratio, ultraviolet transmittance, infrared blocking rate, total solar energy blocking rate, traffic signal recognition, secondary image deviation, optical distortion, orange peel effect, haze, abrasion resistance, temperature resistance, organic solvent resistance, volatile organic compounds, flame resistance, radiation resistance, aging resistance, mechanical properties, human head model impact performance, and heating dimensional change rate. The specific technical indicators and requirements are stipulated in this standard and have been verified through quality testing. The detailed technical requirements can be found in the standard text.
