Passive Monitoring with Corrosion Coupons
Passive Assessment: Corrosion Classification Coupons
for Industrial, Commercial and Water-Wastewater Applications
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.
- 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 (there is no
additional charge for the assessment).
- 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.
