CORROSION DIAGNOSIS OVER A 30-DAY TIME PERIOD
Corrosion Coupons have copper and silver metal strips. These metals represent the sensitive electronic components you rely on when exposed to the air in your environment. Over the course of a 30-day installation period, any corrosive air present will cause build up on the surface of these metal strips. After 30 days, the coupon is sent back to our lab for analysis where our scientists work to determine the air quality classification of the environment. You will receive a detailed report and a results-based solution to help determine next steps.
Additionally, the Corrosion Coupon+ contains a temperature and relative humidity logger for evaluation of controls and limits. Temperature should be maintained consistent with electronic equipment warranty requirements or at the lowest level possible consistent with personal comfort, typically 72°F, 22°C (±2°F, ±1-2°C). Relative Humidity should be less than 50% with close control of deviations, no greater than 6% per hour.
Since installing the complete Purafil solution, electronics failure has been eliminated, and they continue to maintain an G1 environment as classified by the International Society of Automation (ISA) Standard 71.04-2013 “Environmental Equipment Conditions for Process Management and Control Systems: Airborne Contaminants” - India’s Largest Telecom Company
Since utilizing Purafil, this critical control room has maintained a corrosion free environment for over 10 consecutive years. - A Major Paperboard Manufacturer
Purafil was selected because of their experience in the industrial marketplace and superior performance of their air purification systems. Purafil provided the technical knowledge and equipment necessary to build controlled environments that would protect production processes, and meet the standards established by the International Society of Automation (ISA). - World’s Largest Refinery

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.
