salt vs cass

[JPI]

1. How many hours of salt spray ASTMB117 equals to Cass
testing? Ex: 500 hours of salt equals ______ cass.

2. I get asked a lot for every 100 hours of salt spray
what does that represent say in Flordia. How many years
days or months. I need a guide line to follow. Can you
advise?

Can't address CASS vs salt. But for ASTM B-117 salt spray testing, there is no correlation to the real world.
