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-810G, Method 514.6, Procedure I, Category 24 (General Minimal Integrity Test) for the Toughbook 19 and 31. The Toughbook U1 was tested to the MIL-STD-810G, Method 514, 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, the Toughbook 19, 31 and U1 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, the Toughbook computer is 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 Toughbook computers during vibration tests.
