health and safety. If Lenovo determines that the levels of particulates or gases in your environment have
caused damage to the device, Lenovo may condition provision of repair or replacement of devices or parts
on implementation of appropriate remedial measures to mitigate such environmental contamination.
Implementation of such remedial measures is a customer responsibility.

Ta le 1. Limits for particulates and gases
Contaminant Limits
Reactive gases Severity level G1 as per ANSI/ISA 71.04-19851:
• The copper reactivity level shall be less than 200 Angstroms per month (Å/month ≈ 0.0035 μg/
cm2-hour weight gain).2
• The silver reactivity level shall be less than 200 Angstroms per month (Å/month ≈ 0.0035 μg/
cm2-hour weight gain).3
• The reactive monitoring of gaseous corrosivity must be conducted approximately 5 cm (2 in.) in
front of the rack on the air inlet side at one-quarter and three-quarter frame height off the floor
or where the air velocity is much higher.
Airborne
particulates Data centers must meet the cleanliness level of ISO 14644-1 class 8.
For data centers without airside economizer, the ISO 14644-1 class 8 cleanliness might be met by
choosing one of the following filtration methods:
• The room air might be continuously filtered with MERV 8 filters.
• Air entering a data center might be filtered with MERV 11 or preferably MERV 13 filters.
For data centers with airside economizers, the choice of filters to achieve ISO class 8 cleanliness
depends on the specific conditions present at that data center.
• The deliquescent relative humidity of the particulate contamination should be more than 60%
RH.4
• Data centers must be free of zinc whiskers.5

contaminants. Instrument Society of America, Research Triangle Park, North Carolina, U.S.A.
2 The derivation of the equivalence between the rate of copper corrosion growth in the thickness of the corrosion
product in Å/month and the rate of weight gain assumes that Cu2S and Cu2O grow in equal proportions.
3 The derivation of the equivalence between the rate of silver corrosion growth in the thickness of the corrosion
product in Å/month and the rate of weight gain assumes that Ag2S is the only corrosion product.
4 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.
5 Surface debris is randomly collected from 10 areas of the data center on a 1.5 cm diameter disk of sticky
electrically conductive tape on a metal stub. If examination of the sticky tape in a scanning electron microscope
reveals no zinc whiskers, the data center is considered free of zinc whiskers.
