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 20°C to 60°C

LOW TEMPERATURE

-20°C

Frozen at -20°C for over 72 hours

HIGH TEMPERATURE

30°-60°C

+30°C to +60°C over 7 x 24 hour cycles

SAND TEST

x6 HOUR CYCLES

Subjected to 140 mesh silica dust for 6 hour cycles

HIGH VIBRATION

MULTIPLE TESTS

Undergoes multiple tests while switched on and off

MECHANICAL SHOCK

x18 TIMES
