or gases in your environment have caused damage to the server, Lenovo may condition provision of repair or replacement of servers or parts on implementation of appropriate remedial measures to mitigate such environmental contamination. Implementation of such remedial measures is a customer responsibility.

Table 2. Limits for particulates and gases

Contaminant	Limits
Particulate	• The room air must be continuously filtered with 40% atmospheric dust spot efficiency
	(MERV 9) according to ASHRAE Standard 52.21.
	• Air that enters a data center must be filtered to 99.97% efficiency or greater, using
	high-efficiency particulate air (HEPA) filters that meet MIL-STD-282.
	• The deliquescent relative humidity of the particulate contamination must be more than 60%2.
	• The room must be free of conductive contamination such as zinc whiskers.
Gaseous	• Copper: Class G1 as per ANSI/ISA 71.04-19853
	• Silver: Corrosion rate of less than 300 Å in 30 days
