Temperature and humidity specifications

IEC 60601-2-33: 6.8.2 (jj)

Use the specifications listed in Table 1 for designing your HVAC (heating, ventilation, and air conditioning) in your MR system suite. Proper insulation and moisture barrier should be installed within the environmental controlled space (e.g. area above drop ceiling) for humidity, condensation, and temperature control.

Note: To help prevent a patient from feeling uncomfortably warm during a scan, make sure the magnet room temperature does not exceed 69.8.F (21.C) maximum. If the scan room temperature exceeds 72.14°F (22.3°C), then the SAR is automatically derated, which means that the current scan parameters may trip the SAR monitor.

Operator's Control Room	59-89.6* (15-32)*	5 (3)	30-75*	5
* Non-condensing humidity with 50% nominal at 65.F (18.3.C).
