Vibration Resistance

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 and Toughpad tablets to assure they can keep performing in these environments.

The vibration test is typically performed in accordance with MIL-STD-810G, Method 514.6, Procedure I, Category 24 (General Minimal Integrity Test) and Method 514.6, Procedure II (Loose Cargo Transportation). In addition, select models are also tested in accordance with Method 514.6, Procedure I, Category 24 (Helicopter Minimal Integrity Test). All three Toughbook computers were also tested to Method 514.6, Procedure II (Loose Cargo Transportation).

In addition to MIL-STD testing, Toughbook fully-rugged computers were tested in accordance to ASTM D4169-04 (99) Schedule E, Truck Highway Assurance Level II, Operating. The vehicle vibration test conditions used were from 1-200Hz, 0.52 Grms in all three axis, 90 minutes per axis. ASTM (American Society for Testing and Materials International) was founded in 1898 and is one of the largest voluntary standards developing organizations in the world.



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, Toughbook computers and Toughpad tablets are subjected to continuous vibration.

Beyond MIL-STD: Hard disks are especially vulnerable when subjected to vibration. That is why Panasonic runs a video — a disk intensive task - on our computers during vibration tests.
