2.2.2 GR-63-CORE indoor controlled environmental
space
GR-63-CORE indoor controlled environmental space requires:
• continuous, ambient operating temperature of 40°C measured at inlet air to shelf
• relative humidity of 5% to 85% non-condensing
• maximum altitude of 6 kft.
The 40°C operating temperature can be exceeded with a short-term, temporary
temperature up to 55°C measured at the air inlet, provided that the increase lasts for
a period of no more than 96 consecutive hours, and for a total of no more than
15 days a year, and that the environmental space does not exceed the maximum
yearly levels of contamination identified in Table 4.
Table 4 Maximum yearly levels of contamination — GR-63-CORE
indoor controlled environments
Note 1 — “15 days a year” refers to a total of 360 hours in any
given year, and no more than 15 individual occurrences during
a year.
Note 2 — A fan filter must be installed in the equipment and
replaced on a preventive maintenance schedule.
