The worst of any of these tests is the prevailing recommendation of compatibility. A test coupon sourced from McMaster Carr is cut into a 1” x 1” square and weighed and measured. The prevailing method we use for compatibility is weight. The measurements can be used if there is a noticeable physical change. IF there is noticeable cracking or physical breakdown that warrants a non-compatibility, but the weight passed, the compatibility will be based off of the physical. A new coupon is used for each immersion. The coupons are immersed in a sealed container for the prescribed time and then taken out. They are dried for 2 minutes, allowing for surface evaporation, and then weighed.
