Applied Technical Services performs immersion testing services in compliance with ASTM G31, ASTM G44, and ASTM D870. Long-term or intermittent exposure to liquids can alter the physical and chemical characteristics of a material or coating. In applications where liquid exposure is certain or possible, manufacturers rely on immersion corrosion tests to determine how their products resist liquid-induced degradation. Our environmental testing lab conducts immersion tests in compliance with common ASTM testing standards.
What is Immersion Corrosion Testing?
Immersion corrosion testing evaluates how protective coatings perform in aqueous environments. The technical objective of an immersion corrosion test is to measure a coating’s material loss, degradation, or surface changes. Immersion corrosion tests are common in industries where products may be intermittently or continuously submerged in liquids, such as the aerospace, automotive, manufacturing, and electronics industries. There are several prominent industry-standard immersion corrosion tests, but ASTM G31, G44, and D870 are among the most popular.
Our Immersion Corrosion Testing Services
Applied Technical Services conducts immersion tests in accordance with ASTM G31, ASTM G41, and ASTM D870 or in alignment with our clients’ specific requests. We perform tests in a controlled environment, enabling us to follow the specific procedures required for each respective standard. Upon completion of our services, clients will receive reliable, comprehensive data reports that provide critical insights into the immersion-related strengths and weaknesses of their protective coatings or metal materials. Our lab specializes in the following:
- Immersion corrosion testing of metals (ASTM G31)
- Alternate neutral 3.5% sodium chloride solution immersion exposure for metals (ASTM G44)
- Water resistance of coatings (ASTM D870)
Why is Immersion Testing Important?
Immersion testing plays a critical role in identifying a coating or material’s vulnerabilities to aqueous, corrosive conditions. Immersion corrosion tests simulate real-world conditions, enabling experts to determine if a sample has the anti-corrosive properties needed for its intended application. The information collected from tests can aid in the following:
- Improving quality assurance programs
- Optimize protective coating formulas
- Supporting research and development strategies
- Material selection processes
