CORROSION COUPON

Environmental Monitoring

Copper-silver corrosion test coupons placed indoors can provide insights into the potential impact of corrosive gases on computer performance after one month. These test coupons are a typical passive monitoring device exposed to the environment, with a monitoring period ranging from 30 to 90 days. The corrosion reports obtained from copper-silver corrosion test coupons represent the cumulative effect of various corrosion layers. This method assesses the “average” environmental conditions over a specific period and is also an indicator of the types and relative severity of corrosive gases.

Table: ISA Corrosion Degree

Level Degree Model
G1 Mild The environment is sufficiently controlled that corrosion is not a factor affecting equipment reliability
G2 Moderate The impact of corrosion in the environment can be measured and corrosion may be a factor affecting the reliability of equipment
G3 Harsh The possibility of corrosion in the environment is very high. After further evaluation of the severity of the environment.
GX Severe Only specially designed equipment can survive in such an environment. The technical specification of this class of equipment is a point of discussion between the customer and the supplier .
