The main purpose of UV aging test for automotive glass film is to evaluate its weather resistance and durability to determine its service life and performance stability in outdoor environment. Ultraviolet aging test can simulate the influence of ultraviolet radiation in sunlight on automotive glass film materials.

The influence of ultraviolet rays on automobile glass film
Here are some specific reasons why:

Assessing weather resistance: Automotive glass films are exposed to outdoor environments and can be affected by ultraviolet light, high temperature, humidity changes and other factors. Uv aging tests can simulate these factors to evaluate the weatherability of glass films under actual use conditions.

Evaluate performance stability: UV radiation can have adverse effects on automotive glass film materials, zoals kleurvervaging, vergeling, verslechtering, enz. Door UV-verouderingstest, de prestatiestabiliteit van glasfilm kan worden geëvalueerd om te bepalen of deze de vereiste prestaties kan behouden tijdens langdurig gebruik.

Zorg voor kwaliteitscontrole: Door het uitvoeren van UV-verouderingstests, de kwaliteit van autoglasfilms kan worden gecontroleerd en geverifieerd om ervoor te zorgen dat de producten voldoen aan de relevante kwaliteitsnormen en specificaties.

Begeleiden van productverbetering en -ontwikkeling: Door de resultaten van UV-verouderingstests, de prestatieveranderingen van glasfilms onder UV-straling kunnen worden begrepen, om de verbetering en ontwikkeling van producten te begeleiden om hun weersbestendigheid en duurzaamheid te verbeteren.

Door middel van UV-verouderingstests, important information about the durability and stability of automotive glass films in outdoor environments can be provided, helping manufacturers and consumers to make informed decisions and ensuring that products can work safely and reliably in various climatic conditions.

Industry standards
Industry standards for automotive glass films may vary from region to region and country to country. The following are some common international and regional standards and specifications applicable to the performance and quality control of automotive glass films:

ISO 9001:2015: International standard for quality management systems, applicable to a variety of industries, including automotive glass film manufacturers.

ISO 14001:2015: International standard for environmental management systems for environmental management and sustainable development.

ASTM D1044: Standard test method for scratch resistance of Plastic materials, which can be used to evaluate the scratch resistance of automotive glass films.

ANSI/ISEA 105: Standard specification for the Wear resistance of protective gloves, part of which (Sectie 3.21) is applicable to the testing of the wear resistance of glass films.

ANSI/SAE Z26.1: A standard published by the American Society of Automotive Engineers (SAE) for automotive safety glass, part of which (Sectie 5.1) applies to the visible light transmittance requirements of automotive glass films.

In aanvulling, some countries or regions may have specific standards and specifications, such as FMVSS 205 (Federal Motor Vehicle Safety Standard) in the United States and ECE R43 (Economic Commission for Europe regulation) in Europe, which apply to the requirements of visible light transmittance and perspective of automotive glass films.

Specifically, according to the requirements of the region and the target market, the applicable standards and specifications should be selected, and the products should ensure that they meet the relevant quality and performance requirements. Manufacturers often refer to applicable national and regional regulations to ensure that their products are legal in the market and comply with requirements.

Specific application cases
The following are some specific application cases of automotive glass films:

UV protection: Automotive glass films can provide ultraviolet (UV) protection, reducing UV damage to the passengers and interior of the car. This helps reduce the risk of skin cancer and sunburn, and reduces aging and fading of materials in the car.

Privacy protection: Car glass film can increase the privacy of the car window, preventing others from peeping into the car from the outside. This plays a role in protecting driver and passenger privacy, property safety and preventing theft.

Heat control: The transparent high-performance automotive glass film can reduce the entry of solar heat, reduce the interior temperature, provide a more comfortable driving and riding experience, reduce the load on the air conditioning system, and save fuel.

Glass breakage protection: Safety automotive glass film can increase the impact resistance of glass, reduce the splashing of debris caused by accidents, collisions or breakage, and protect drivers and passengers from injury.

Landscaping: Decorative automotive glass films can add a personalized look to vehicles, making them more attractive and unique through designs such as different colors, patterns, and decals.

Deze toepassingsgevallen vormen slechts een klein deel van autoglasfilms, en de praktische toepassingen kunnen meer worden aangepast en uitgebreid volgens verschillende behoeften en markttrends. Autoglasfolie heeft een verscheidenheid aan functies en voordelen, die het rij- en rijcomfort kunnen verbeteren, veiligheid en privacy.

Werkwijze
Bij het testen van de verouderingsbestendigheid van autoglasfilms, de UV-verouderingstestkamer kan worden gebruikt om de UV-straling in zonlicht en andere omgevingsomstandigheden te simuleren. Hieronder volgen de stappen en voorzorgsmaatregelen voor het testen van de verouderingsbestendigheid van autoglasfilm met behulp van een UV-verouderingstestkamer in het algemeen:

Monstervoorbereiding: Volgens de normen of eisen, selecteer de juiste maat autoglasfilmmonsters om te testen. Ensure samples comply with relevant specifications and requirements.

Test condition setting: according to the required test conditions and standard requirements, set the parameters of the UV aging test chamber, including radiation intensity, temperatuur, vochtigheid, enz. Be careful to set correctly according to standards or requirements.

Sample placement: Paste the automotive glass film sample on the test plate to ensure that the sample surface is smooth, free of bubbles and wrinkles, and avoid mutual interference between samples.

Test run: Start the UV aging test chamber and expose the sample to UV radiation under the set conditions. According to the standard requirements, set the appropriate test time, usually hundreds to thousands of hours.

Regular observation: Regularly observe the changes of the sample, including color change, fading, vergeling, verslechtering, enz. Record any visible changes or damage.

End of test and evaluation: Upon completion of the test, samples were removed for evaluation and testing. The physical and optical properties of automotive glass film can be tested to determine its aging resistance.
