High levels of vibration can wreak havoc with ordinary mobile computers, especially those used regularly in vehicles. Even in stationary environments, such as shops and factories, computers need protection from vibrations. Panasonic tests fully-rugged Toughbook computers to assure they can keep performing in these environments.

The vibration test is performed in accordance with MIL-STD-810F, Method 514, Procedure I, Category 24 (Minimum Integrity Test) for the non-operational condition and Category 20 (Ground Vehicles) for the operational condition. Clamped to an aluminum plate to approximate rigid mounting, a fully-rugged Toughbook laptop is subjected to the following levels of vibration:

• Non-Operational (from Figure 514.5C-17 of MIL-STD-810F) 0.04 g2 /Hz at 20-1000 Hz, -6 dB/Octave at 1000-2000 Hz, 1 hour/axis duration.

• Operational (Figure 514.5C-1 of MIL-STD-810F) 0.001 g2 /Hz at 12.5 Hz, 0.034 g2 /Hz at 20~40 Hz 5.70E-06 g2 /Hz at 200 Hz, 1 hour/axis duration simulating 1000 miles of transportation.

Panasonic's vibration test goes beyond MIL-STD requirements. During the operational test, while the hard disk drive is spinning and being accessed to play a video, the Toughbook computer is subjected to continuous vibration.
