ASTM G85 Modified Salt Spray Durability Testing for Automotive Metals
The ASTM G85 modified salt spray durability testing is a critical procedure used to evaluate the resistance of automotive metals to corrosion caused by salt fog exposure. This test closely follows the ASTM G85 standard, with modifications tailored specifically for the automotive sector where materials are exposed to harsh environments such as coastal regions or areas with frequent road salting.
This method simulates real-world conditions that automotive components may encounter during their operational life. The test is particularly useful in assessing the durability of metals used in car body panels, suspension systems, and other external parts that are regularly exposed to salt-laden environments. By subjecting these materials to a controlled salt spray environment for extended periods, we can predict how well they will perform under actual use.
The modified ASTM G85 test is especially beneficial when dealing with alloys like aluminum, zinc-coated steels, and other high-performance metals used in modern automotive designs. The test setup includes a specialized chamber where the specimens are exposed to a continuous spray of salt water vapor at specific temperature and humidity levels. This controlled environment accelerates the corrosion process, allowing for accelerated aging tests.
The apparatus required for this testing includes a salt fog chamber capable of maintaining precise temperature control and a consistent level of relative humidity. Specimens must be carefully prepared by cleaning them thoroughly to remove any surface contaminants that could affect the test results. After preparation, samples are mounted in the chamber using standardized clamps or holders.
The acceptance criteria for this test involve evaluating the integrity of the metal coating after exposure. A pass/fail decision is made based on visual inspection and measurement of remaining coating thickness. This ensures that manufacturers can confidently use materials that have passed these stringent tests, knowing they will provide reliable performance in corrosive environments.
Our laboratory adheres strictly to international standards such as ASTM G85, ensuring accurate and reproducible results. By providing this service, we help automotive companies maintain compliance with industry regulations while also enhancing product quality through rigorous testing protocols.

Why Choose This Test
The ASTM G85 modified salt spray durability testing is chosen by many automotive manufacturers because it provides reliable and repeatable results. It helps ensure that the materials used in vehicles can withstand harsh environmental conditions, thus improving overall vehicle reliability.
This test offers several advantages over other methods of evaluating metal corrosion resistance:
- It accurately simulates real-world exposure scenarios.
- Results are highly reproducible and consistent.
- It allows for accelerated testing to shorten development cycles.
The primary advantage lies in its ability to predict how well a material will perform under actual use conditions. This makes it an invaluable tool during the design phase of new vehicles, helping engineers make informed decisions about which materials to use and how they should be treated.
By choosing this test, companies can save time and money by identifying potential problems early in the development process rather than discovering them after production has already begun. This not only improves product quality but also enhances customer satisfaction and brand reputation.
