The humidity limits are derived from a psychrometric chart using a maximum wet bulb temperature of 29 _C. The highest
1
RH (20%) at the maximum temperature (+60 _C) diverges from the psychrometric chart (which would indicate 6%). The
20% number is a practical limit. Test chambers cannot be set below this number.

Description
(–55 _C to +75 _C)
The environmental exposure is the procedure stated in Tektronix Design Standard
062-2847-00 for Class 6 equipment.
0 _C to +40 _C (32 _F to 104 _F)
This procedure conforms to the temperature portion of the test in MIL-T-28800E for
Type III, Class 6 equipment, using the limits above.
0% to 75% relative humidity from +30 _C to +60 _C.
0% to 80% relative humidity to +31 _C, decreasing at a linear rate to 50% at +40 _C,
minimum.
