What are the application scenarios of xenon lamp aging test chamber in the automotive industry?

The core application scenario of xenon lamp aging test chamber in the automotive industry - (accurately matching automotive R&D/quality inspection needs, focusing on key components and testing value)

1、 Weather resistance test for exterior components

Body coverings: bumper, fenders, door panels, trunk lid

Test objective: To simulate outdoor exposure to sunlight and rain, and verify the UV aging, cracking, and fading resistance of plastic/composite materials

Core value: To avoid yellowing of the paint surface and cracking of plastic parts after 1-3 years of vehicle use

Lamp system: front headlight housing, tail light cover, turn signal lampshade

Test purpose: To test the transmittance attenuation and yellowing resistance of PC/PMMA material

Core value: Ensure that the transparency of car lights meets the standard after long-term use, without affecting lighting safety

Other exterior decorations: rearview mirror shell, door handle, luggage rack, window sealant strip

Test purpose: to verify the stability of aging resistance, deformation resistance and sealing performance

Core value: prevent cracking and leakage of rubber strips, deformation and detachment of plastic parts

2、 Light aging resistance test for interior parts

Core components of the cockpit: dashboard, center console, seat leather/fabric, steering wheel, door interior panels

Test purpose: Simulate the sunlight through the window to test the anti fading, anti-aging and anti stick performance

Core value: To prevent the interior from fading, leather cracking, and plastic parts from sticking after long-term exposure to sunlight

Interior decorations: ceiling, carpet, sun visor, storage box

Test purpose: To verify the color fastness and wear resistance of fabric/plastic materials

Core value: Ensure that the interior remains clean and tidy after long-term use, with no obvious signs of aging

Car electronic screens: central control screen, dashboard display screen, head up display panel

Test purpose: To test the anti UV aging and anti reflection performance attenuation of the screen surface coating

Core value: Ensure that the screen is clear and visible for a long time, and the operational sensitivity is not affected

3、 Testing of electronic appliances and functional components

In car electronic devices: car infotainment system, sensors, cameras, radar modules

Test purpose: simulate the high temperature+light composite environment, and verify the stability of electronic components and the anti-aging capability of circuit boards

Core value: To prevent equipment from malfunctioning due to high temperature and exposure during outdoor parking

Wires, cables, and connectors: engine compartment wiring harness, interior wiring, connectors

Test purpose: To test the insulation layer's resistance to UV aging, cracking, and high/low temperature

Core value: Prevent wire harness aging and short circuit, ensure driving safety

Rubber and elastic components: shock absorbers, sealing rings, water pipes, oil pipes

Test purpose: Simulate sun exposure+high and low temperature cycling to verify the anti cracking, anti hardening, and fatigue resistance performance

Core value: Extend the service life of components, avoid leakage and failure risks

4、 Testing of Coatings and Coating Systems

Car body paint surface: original car paint, repair paint, clear coat layer

Test purpose: To test color fastness, glossiness attenuation, and scratch resistance performance

Core value: Ensure long-term gloss, corrosion resistance, and fade resistance of the car body paint surface

Component coating: anti rust coating for chassis components, spray coating for interior parts

Test purpose: to verify the adhesion, anti-aging and anti peeling properties of the coating

Core value: Prevent component rusting, coating peeling, and enhance vehicle durability

5、 Core application value

Shorten R&D cycle: Complete outdoor aging testing for several years in a few weeks, accelerate the validation of new materials/components;

Reduce after-sales risks: detect aging defects in advance to avoid recalls due to quality issues after mass production;

Compliant with industry standards: Meets specialized aging testing standards for the automotive industry such as ISO 16474, SAE J2527, ASTM G155, etc;
