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.
