Comprehensive Guide on Copper and Silver Corrosion Monitoring

Corrosion is a prevalent issue in several industrial and mission-critical settings. It can cause significant damage to equipment and artefacts, necessitating expensive repairs or replacement. Monitoring corrosion regularly and deciding the necessary remedial steps to protect the assets to limit its consequences is essential. Corrosion Classification Coupon (CCC) serves this purpose. The CCC analyses the amount of corrosion that occurs on copper and silver surfaces, giving data that allows the industry to classify the corrosion present and identify class contaminants.

Copper and silver are utilized in Purafil's CCC approach for passively monitoring reactivity. The coupons are deployed in various locations, including control rooms, data centres, clean production facilities, museums, and libraries. The CCC is a cost-effective investment that yields scientifically backed and trustworthy data, making it the best-measuring air quality. The CCC's discreet and straightforward installation makes it a practical choice for corrosion monitoring.

The classic saying of Desiderius Erasmus, "Prevention is better than cure," applies to corrosion. By monitoring the corrosion rate using CCCs, manufacturers may identify what activities are necessary to prevent further deterioration of equipment and assets. The paperwork supplied by Purafil's CCC report is also essential for manufacturers' compliance with warranty requirements.

After a 30-day installation period, the CCCs are collected and delivered to the laboratory of Purafil for assessment. The study's objective is to determine the kind and thickness of the corrosion films on the surface of each metal coupon. The laboratory determines a normalized 30-day reactivity rate by utilizing the period the metal sample was exposed to and the corrosion's thickness.

The ISA Environmental Classes:?Airborne Contaminants standard declares that rooms with backplane-wired equipment, instrumentation, process control systems, or computers must have a G1 environmental classification. In terms of corrosion thickness, the categorization is 0-299 Angstroms () per 30 days for copper and 0-199 per 30 days for silver coupons. Purafil offers a report that corresponds precisely to the G1, G2, G3, and GX ratings, as stated by the ANSI/ISA-71.04-2013 standard.

The ISA standard classifies corrosion severity as follows:

G1 - Mild (Copper: <300 Angstroms/30 days; Silver: <200 Angstroms/30 days)

G2 - Moderate (Copper: <1000 Angstroms/30 days; Silver: <1000 Angstroms/30 days)

G3 - Harsh (Copper: <2000 Angstroms/30 days; Silver: <2000 Angstroms/30 days)

GX - Severe (Copper: >2000 Angstroms/30 days; Silver: >2000 Angstroms/30 days)

In corrosion monitoring, the proverb "measure twice, cut once" is equally applicable. It is essential to constantly monitor the corrosion rate and take corrective action to prevent additional damage. The ISA standard offers a comprehensive framework for assessing the degree of corrosion and identifying the necessary procedures to avoid future deterioration of equipment and assets.

According to the adage attributed to Benjamin Franklin, "an ounce of prevention is worth a pound of cure." By employing corrosion classification coupons to monitor the degree of corrosion in the environment, industries, museums, and clean-room facilities may take preventative measures to safeguard equipment, processes, and artefacts from corrosion's harmful impacts. With the scientific precision and dependability of Purafil's CCCs, there is no reason not to prioritize corrosion monitoring.
