Temperature Storage

7 days at +165 F (+74 F) degrees, unpackaged.
7 days at -20 F (-29 C) degrees, packaged.
After each 7-day storage period, units must be allowed to stabilize for 24 hours before testing.
Units must operate per Section V.

Temperature Cycling

5 cycles from -20 F (-29 C) degrees to +165 F (+74 C) degrees. Allow 24 hours for stabilization
before testing. Units must operate per Section V specifications mechanically and electrically.
Operational Temperature
Operate units as described in Section V at +0 F (-18 C) and +135 F (+57.9 C) degrees. Allow
three hours for stabilization of each temperature before testing. Units must operate per Sec-
tion V specifications.

Steady State Humidity

Perform a 10 day test at 90% RH at room temperature. Evaluate units for visual and mechan-
ical defects after 1, 3, 5, 7, and 10 days. At the end of the 10-day period allow the units to
recover for 24 hours. Units must pass Section V specifications.
Operational Humidity
Operate units as described in Section V at 90% RH at room temperature.
Allow two days for stabilization.
Moisture Resistance
Perform a 10-day test at 90% to 98% RH with temperature cycled between +14 F (-10 C) and
+150 F (+65 C) degrees. Allow the units to recover for 24 hours. Product must meet Section
V specifications.
Mechanical Shock
Handheld Drop Test: Drop product from a height of 6' onto a hardwood floor for a total of 10
drops. The unit must pass Section V specifications.
Stand Drop Test: Place product on a stand with the appropriate size swivel adapter. Drop unit
from a height of 5' onto a hardwood floor for total of 10 drops. The product must meet Section
V specifications.
Electrostatic Discharge
