Particulate contamination Specifications
NOTE: Air filtering can also be accomplished by filtering
room air with MERV8 filter per ANSI/ASHARE Standard
127.
Conductive dust Air must be free of conductive dust, zinc whiskers, or other
conductive particles.
NOTE: This condition applies to data center and non-
data center environments.
NOTE: Common sources of conductive dust include
manufacturing processes, and zinc whiskers from the
plating on the bottom of raised floor tiles.
Corrosive dust • Air must be free of corrosive dust.
• Residual dust present in the air must have a deliquescent point
less than 60% relative humidity.
NOTE: This condition applies to data center and non-
data center environments.

Copper Coupon Corrosion rate <300 Å/month per Class G1 as defined by ANSI/ISA71.04-2013
Silver Coupon Corrosion rate <200 Å/month as defined by ANSI/ISA71.04-2013
NOTE: Maximum corrosive contaminant levels measured at ≤50% relative humidity.
