I need details about mil-std (military standards) for ruggedness of computers (desktops, laptops, etc).

I can find "This laptop is semirugged" but I can't find out what that means.

Hoping someone can point me to a site that descibes it better.

I think Tempest grade electronics have passed some kind of military standard. Wiki might have more to say.

Electronics ruggedization milspec is MIL-STD-810F


Edit: It depends on what categories the device is rated for. Milspec rugged means it passes all of them (generally). You should look at a detailed breakdown of the device specifications if you need one for a special purpose.

http://en.wikipedia.org/wiki/MIL-STD-810

It can be any combination of the things listed on that page.

what the hell is ruggedness?

A measurement of durability i assume.

Durability and resistance to environmental hazards.

Covers things like gunfire vibrations, funguses, humidity, direct exposure to water, extreme temperatures, freezing water, extreme air pressures and rapid changes in all of these elements.

There is no set standard for what "rugged" is. It depends on the device and the intended use, which is why any product that claims to pass parts of MIL-STD-810F should include a spec sheet.
