Leading Manufacturer, Supplier & Retailer of Corrosion Classification Coupon.
Corrosion Classification Coupon
The Corrosion Classification Coupon (CCC) measures the amount of corrosion that forms on copper
and silver surfaces. This provides data allowing an industry standard classification of the amount of corrosion present, as well as identifying contaminant classes. Because many contaminants are corrosive in nature (e.g., hydrogen sulfide and sulfur dioxide), reactivity monitors have long been used to gauge the quality of ambient air and to indicate the effectiveness of pollution control strategies. Purafil’s CCC is
a passive reactivity monitoring technique involving the use of copper and silver.
Customer Benefits
• Unobtrusive, easy installation and data gathering
• Economical investment for determining air quality
• Scientifically supported, reliable results
•Provides the documentation required for manufacturers’
warranty compliance
•Vital for determining corrective solutions to protect
equipment, processes, and artifacts
Copper and Silver Analysis
After an installation period of 30 days, the CCCs are collected from the field and returned to Purafil’s laboratory for analysis. The purpose of CCC analysis is to determinethe type and thickness of corrosion films on the surface of each metal coupon. A normalized 30-day reactivity rate is calculated using the amount of time the metal coupon is exposed and the thickness of the corrosion that has formed.
ISA Environmental Classes: Airborne Contaminants This standard requires that rooms containing backplane wired equipment, instrumentation, process control systems or computers, must have a G1 environmental classification, defined in terms of corrosion thickness as 0-299 Angstroms (Å) per 30 days on copper and 0-199 Å per 30 days on silver Coupons. Purafil provides a report that directly correlates to the G1, G2, G3, and GX ratings.
