This standard specifies the general technical requirements for thermal design of military microcomputers during the development and design stages. This standard applies to conduction cooling, natural cooling (thermal conduction, natural convection and thermal radiation), direct forced air cooling and indirect forced air cooling of computer components, printed board assemblies and complete machines for the army, navy and air force. Design requirements.
