Use Purafil Corrosion Classification Coupons to determine the types and levels of corrosive gases in your control room, motor control center, rack room, or other area housing sensitive electronics. |
HERE'S HOW IT WORKS:
Step 1: Place the coupon in the room of concern for a period of 30 days. Exposing the coupons to the corrosive gases in your environment will result in the buildup of a corrosion film on your coupon.
Step 2: Return the coupon to Purafil’s research and development laboratory for analysis.
Step 3: Purafil will analyze the corrosion buildup on your coupon to determine the rate of corrosion, the types of corrosive pollutants in your environment as well as their relative levels. Purafil will then provide a report detailing the severity of corrosion in the room as defined by the Instrumentation, Systems, and Automation Society (ISA) Standard 71.04-1985, the accepted guideline for warranties of electronic equipment.
Step 4: Meet with your local Purafil representative to determine which areas are in greatest need of protection from corrosive, acid gases. Based on the results of the report, your Purafil representative will be better able to help recommend a customized solution.
