Corrosion Classification Coupon (CCC)

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.

Typical CCC Installation Sites:

Industrial and Mission Critical Environments:

Control Rooms, Rack Rooms, Motor Control Centers, Data Centers, Server Rooms, and Critical Parts Storage Rooms.

Museum and Library Environments:

Recirculation Air Handlers, Storage Rooms, Display Cases, Archives, and Historic Houses.

Clean Room Manufacturing Environments:

Semiconductor, HDD, LED, and more.

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 determine the 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.
