Mil-SPEC is a set of standards designed to test durability, ruggedness and reliability. These tests cover extreme environmental variables including temperature, pressure, dust, humidity and vibration testing.
Although ThinkPads have always been known for their robustness, they were not specifically designed to only meet the Mil-SPEC 810G standard. Meeting the standard is just the start of ThinkPad's durability, robustness and reliability. Selected ThinkPad models, including all X & T series, have successfully passed the following tests:
HUMIDITY
91 - 98%
Subjected to 91-98% humidity at 30°C to 60°C
LOW TEMPERATURE
Storage: -25°C for 24 hrs
Operation: -21°C for 8 hrs
HIGH TEMPERATURE
Storage: 63°C for 24 hrs
Operation: 43°C for 8 hrs
SAND & DUST TEST
x6 HOUR CYCLES
140 mesh silica dust for 6 hr. cycles and silica sand for 90 min. cycles
HIGH VIBRATION
MULTIPLE TESTS
Tested while running and turned off
MECHANICAL SHOCK
x18 TIMES
High acceleration and repeated shock pulses over 18 times
HIGH ALTITUDE
15,000ft
Tests operation at 15,000 feet while running
TEMPERATURE SHOCK
-25° – +60°C
Performs in temperatures oscillating between -25°C and +60°C over 3 cycles of 2 hour duration
SOLAR RADIATION
7 x 24 HOURS
Simulated UV radiation over 7 x 24 hour cycles
FUNGUS
28 DAYS
28 days with common fungus sources
