ASTM D2247 Wheel Coating Moisture Resistance Test
The American Society for Testing and Materials (ASTM) D2247 specifies the procedure for determining the resistance of wheel coatings to moisture ingress. This test is crucial in ensuring that protective coatings used on automotive wheels can withstand exposure to moisture, which is a common issue leading to corrosion and degradation.
The ASTM D2247 test involves exposing coated specimens to a high humidity environment over an extended period and then evaluating the degree of water absorption through the coating. The primary objective of this test is to provide manufacturers with reliable data on how well their coatings perform under real-world conditions, thereby enhancing product longevity and safety.
The process typically includes several key steps:
- Preparation of coated wheel specimens
- Humidity conditioning in a controlled environment
- Measuring the weight gain or loss after exposure to moisture
- Evaluation against industry standards and acceptance criteria
The test is particularly important for industries where high reliability and performance are critical, such as automotive manufacturing. Compliance with this standard ensures that products meet stringent quality control requirements.
| Conditioning Time | Humidity Level | Specimen Weight Gain/Loss (%) |
|---|---|---|
| 72 hours | 95% | ≤1.0% for compliant materials |
The test results are essential for quality assurance and compliance with international standards such as ISO, ASTM, EN, and IEC. Automotive manufacturers rely on this data to ensure their products meet the highest safety and performance standards.
