Key Applications in Automotive Testing
1. Interior Components – Fading & Cracking
-
Challenge: Dashboards, upholstery, and steering wheels are exposed to intense sunlight.
-
Test Standard: ISO 105-B10 (color fastness to light).
-
Validation Goal: Prevent fading, brittleness, and cracking.
-
Benefit: Ensures interior aesthetics and customer satisfaction.
2. Exterior Coatings & Plastics
-
Challenge: Bumpers, mirror housings, and paint finishes face UV degradation, moisture, and thermal cycling.
-
Validation Goal: Maintain color stability and coating adhesion.
-
Test Standards: OEM-specific weatherability requirements (often >10 years).
-
Benefit: Supports warranty compliance and reduces maintenance claims.
3. Functional Components – Belts, Seals, and Gaskets
-
Challenge: Exposure to ozone and extreme thermal cycles.
-
Test Standard: ISO 1431-1 (ozone resistance).
-
Validation Goal: Prevent premature failure of safety-critical parts.
-
Benefit: Avoids costly recalls and safety issues.
