Rubber Product Testing Methods: Key Quality Tests & Why They Matter
The performance and durability of ubber products rely on strict quality control and testing. The following explains "Material Property Tests" and "Vibration & Durability Tests" to help customers understand the purpose and importance of each.
1. Material Property Tests
These fundamental tests evaluate raw materials or finished rubber parts to ensure stable performance and suitability for various applications.
| Test Item | Standard | Purpose & Importance |
|---|---|---|
| Hardness Test | ASTM D2240 | Measures hardness, affecting sealing, cushioning & fit |
| Tensile Strength & Elongation | ASTM D412 | Evaluates tensile strength & flexibility for durability |
| Tear Strength | ASTM D624 | Prevents crack propagation and structural failure |
| Compression Set | ASTM D395 | Assesses rebound ability & long-term sealing performance |
| Heat Aging Test | ASTM D573 | Ensures material stability under high-temperature environments |
| Ozone & Weather Resistance | ASTM D1149 | Prevents surface cracking & aging caused by the environment |
| Oil Resistance | ASTM D471 | Ensures stable performance after exposure to oils |
| Flammability Test | FMVSS 302 / ASTM D5132 | Meets flammability safety standards |
| Electrical Insulation | ASTM D149 | Guarantees insulation performance for electronic & electrical products |
2. Vibration & Durability Tests
These tests focus on the functionality and durability of rubber vibration dampers under real-life conditions.
| Test Item | Standard | Purpose & Importance |
|---|---|---|
| Stiffness Test for Dampers | Per Customer Spec or Internal Standard | Tests directional stiffness for structural support & vibration isolation |
| Dynamic Fatigue Test | Per Customer Spec or Internal Standard | Simulates cyclic loading to verify fatigue resistance & long-term durability |
