Table 7. Particulate Contamination . This describes Particulate Contamination
NOTE: This section defines the limits to help avoid IT equipment damage and/or failure from particulates and gaseous contamination. If it is determined that levels of particulates or gaseous pollution are beyond the limits specified below and are the reason for the damage and/or failures to your equipment, it may be necessary for you to re-mediate the environmental conditions that are causing the damage and/or failures. Re-mediation of environmental conditions will be the responsibility of the customer.
	Air Filtration NOTE: Applies to data center environments only. Air filtration requirements do not apply to IT equipment designed to be used outside a data center, in environments such as an office or factory floor.	Data center air filtration as defined by ISO Class 8 per ISO 14644-1 with a 95% upper confidence limit. NOTE: Air entering the data center must have MERV11 or MERV13 filtration.
	Conductive Dust NOTE: Applies to data center and non-data center environments.	Air must be free of conductive dust, zinc whiskers, or other conductive particles.
	Corrosive Dust NOTE: Applies to data center and non-data center environments.	Air must be free of corrosive dust. Residual dust present in the air must have a deliquescent point less than 60% relative humidity.
Gaseous Contamination
NOTE: Maximum corrosive contaminant levels measured at ≤50% relative humidity.
	Copper Coupon Corrosion Rate	<300 Å/month per Class G1 as defined by ANSI/ISA71.04-1985.
	Silver Coupon Corrosion Rate	<200 Å/month as defined by AHSRAE TC9.9.
