2. Biological Conditions
Animals and plants are strictly prohibited in the server room. This prevents rats and
ants from causing damage to the device.
To meet the requirements, you must take the following measures for the server
room:
Make sure that the humidification system (if any) in the server room is safe.

Measures must be taken to ensure that the structures and construction cracks

of doors, windows, walls, and ground (floor) surfaces are airtight.
If water supply and drainage pipes are provided in the server room, anti-

leakage and anti-condensation measures are required.
If water equipment is provided in the server room, measures must be taken to

prevent water overflow and leakage.
The cable holes and antenna holes in the server room must be blocked and

protected.
Make sure that the sanitation in the server room is good. Regular disinfection is

recommended.
3. Corrosive Gaseous Pollutants
Generally, indoor and outdoor environments contain a small amount of common
corrosive gaseous pollutants. These mixed corrosive gaseous pollutants or a single
corrosive gaseous pollutant may cause a long-term chemical action based on
other environmental factors such as temperature or relative humidity. As a result,
the IT equipment is prone to failure caused by corrosion. The circuit boards of the IT
equipment and the system components with weak anti-oxidation capability may
be damaged. This clause stipulates the restrictions on corrosive gaseous pollutants
to prevent such risks.
The corrosive gaseous pollutants in the data center must meet the requirements of
2011 Gaseous and Particulate Contamination Guidelines for Data Centers
the
white paper is widely used by IT equipment manufacturers. It is prepared by the
American Society of Heating, Refrigerating and Air-Conditioning Engineers
(ASHRAE) Technical Committee (TC) 9.9. According to this white paper, corrosive
gaseous pollutants in data centers must meet the following requirements:
The corrosion rate of the tested copper samples must meet the gas corrosivity

level G1 defined per American National Standards Institute/Instrument Society
of America (ANSI/ISA)-71.04-2013. The thickness growth rate of the corrosion
product of the tested copper samples must be less than 300 Å/month.
The corrosion rate of the tested silver samples must meet the gas corrosivity

level G1 defined per ANSI/ISA-71.04-2013. The thickness growth rate of the
corrosion product of the tested silver samples must be less than 200 Å/month.
