Ruggedized (Rugged) - definition
Ruggedized devices (e.g. mobile phones) offer protection against rough use and/or a rough environment. For example, such devices are normally resistant to shock, water and dust. In order to measure the level of protection manufacturers usually get standard certificates in one or several of the available systems. Such standardization systems include the US Military Standard (MIL-STD or Mil-Spec) or the Ingress protection rating (IP).
