Particulate contamination
Attention: Airborne particulates (including metal flakes or particles) and reactive gases acting alone or in
combination with other environmental factors such as humidity or temperature might pose a risk to the
storage product that is described in this document. Risks that are posed by the presence of excessive
particulate levels or concentrations of harmful gases include damage that might cause the storage product
to malfunction or cease functioning altogether. This specification sets forth limits for particulates and
gases that are intended to avoid such damage. The limits must not be viewed or used as definitive limits,
because numerous other factors, such as temperature or moisture content of the air, can influence the
impact of particulates or environmental corrosives and gaseous contaminant transfer. In the absence of
specific limits that are set forth in this document, you must implement practices that maintain particulate
and gas levels that are consistent with the protection of human health and safety. If Lenovo determines
that the levels of particulates or gases in your environment have caused damage to the storage product,
Lenovo may condition provision of repair or replacement of storage products or parts on implementation
of appropriate remedial measures to mitigate such environmental contamination. Implementation of such
remedial measures is a customer responsibility.
Table 11. 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 52.2
1
.
• 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 71.04-1985
3
• Silver: Corrosion rate of less than 300 Å in 30 days

The deliquescent relative humidity of particulate contamination is the relative humidity at which the dust absorbs
enough water to become wet and promote ionic conduction.

Important WEEE information
The WEEE marking on Lenovo products applies to countries with WEEE and e-waste regulations (for
example, the European WEEE Directive, India E-Waste Management & Handling Rules, 2011). Appliances are
labeled in accordance with local regulations concerning waste electrical and electronic equipment (WEEE).
