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

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
