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

THE REALITY
THE DIAGNOSIS

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.

Step 3 - Place

Once registered, you may now place your coupon! It is important to place the coupon within 24hrs of receiving so it is unaffected by factors outside of the intended testing site. The coupon will need to remain installed in its testing location for exactly 30 days to produce accurate results.

Coupon Testing

Step 4 - Analysis

After an installation period of 30 days, the Corrosion Coupons are collected from the field and returned to Purafil’s laboratory for analysis. The purpose of the 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.

Results

Step 5 - Results

Once analysis is complete, you will receive a detailed report from the lab outlining if corrosion is present in the tested environment along with a tailored solution to combat it. If corrosion levels do not pose a current threat, we can help you figure out the best plan for continued diagnosis.
