Summary for chromated aluminum corrosion Discussion
chromated aluminum in a swimming pool setting raises corrosion concerns because the environment combines high humidity with salt vapour, and Sridhar Ramamurthy asked for a relevant ASTM standard for testing. The only answer in the thread, from McHenry, Illinois, says ASTM B117 salt spray is commonly used for corrosion testing. The responder notes that B117 is not an exact simulation of pool water, but argues that chlorides are the operative corrosive agent in both cases, making it a practical reference test for this kind of exposure. The thread does not discuss long-term performance of chromated 6061 aluminum in detail or offer a pool-specific ASTM standard beyond that suggestion.
Q. Our client would like to use chromated aluminium 6061 alloy parts in the roof structure of a swimming pool? We are wondering about the corrosion issues due to high humidity and the presence of salt vapour.
Also, can someone please kindly let me know the relevant ASTM standards for this application?
Thanks,
Sridhar.

A. ASTM B117 Salt spray is commonly used for corrosion testing. It’s not exactly pool water but the chlorides are the operative corrosive agent in both cases.
