Ensuring Automotive Excellence: How Weathering Test Chambers Validate Component Durability

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.
