ISO/IEC TS 22237-4:2018
Information technology — Data centre facilities and infrastructures — Part 4: Environmental control
ISO/IEC TS 22237-4:2018 addresses environmental control within data centres based upon the criteria and classifications for "availability", "security" and "energy efficiency enablement" within ISO/IEC TS 22237‑1.
ISO/IEC TS 22237-4:2018 specifies requirements and recommendations for the following:
a) temperature control;
b) fluid movement control;
c) relative humidity control;
d) particulate control;
e) vibration;
f) floor layout and equipment locations;
g) energy saving practices;
h) physical security of environmental control systems.
Issues related to electromagnetic environment can be found in ISO/IEC TS 22237‑6.
