*If testing with silver or copper coupons results in values less that 200 Å/month or 300 Å/month, respectively, then operating
up to 70% relative humidity (RH) is acceptable. If the testing shows corrosion levels exceed these limits, then catalyst-
type pollutants are probably present and RH should be driven to 50% or lower.
