From small issues like paint peeling off phone cases or fading car buttons to major problems like outdoor equipment rusting and failing or electronic components short-circuiting, these seemingly "worn-out" problems often have a common culprit: environmental aging. Excessive humidity, sun exposure, salt spray corrosion, and high-temperature baking—products face environmental stress in real-world use that is far more severe than we might imagine. How can we predict a product's "anti-aging" capability in advance?
Aging tests are a critical reliability assessment method. They simulate or intensify various conditions that a product might encounter in actual use, allowing for a quick evaluation of the durability, stability, and lifespan prediction of materials or products.
1. What are the common aging tests?
Type | Simulated Environment | Core Destructive Mechanism | Main Assessment Indicators | Typical Application Scenarios |
|---|---|---|---|---|
Damp Heat Aging | High temperature (40~85°C) + high humidity (85%~100% RH) | Vapor penetration causing material expansion, metal corrosion, electronic short-circuit | Material deformation, coating peeling, insulation performance decline, electrical faults | Electronic devices, plastic casings, packaging materials, automotive harnesses |
Salt Spray Aging | 5%±1% NaCl salt spray (35±2°C) with over 95% relative humidity | Chloride ion penetration causing electrochemical corrosion of metals | Surface rust rate, coating damage, mechanical strength decay | Hardware parts, automotive components, marine accessories, outdoor lighting |
Xenon Lamp Aging | Simulated full-spectrum sunlight (UV + visible + infrared) | Combined light and heat energy causing material oxidation, fading, cracking | Color change (ΔE), gloss reduction, chalking, mechanical performance decay | Outdoor coatings, plastic products, textiles, automotive exteriors |
UV Aging | UV lamp (UVA/UVB) + condensation cycle | UV radiation directly breaking polymer chains, causing material degradation | Yellowing, chalking, cracking, adhesion loss | Roofing materials, plastic films, outdoor furniture, ink coatings |
2. Common Test Standards
