Ingress Protection Testing
Mobile computers are rated according to international standards for ingress protection (IP). IP Codes classify the degrees of protection provided by electrical enclosures from dust, water and impact.
As part of IP particle resistance and liquid resistance testing, Panasonic fully-rugged computers have achieved an IP651 rating. The first digit (6) of IP65 indicates resistance to dust. The computer is not completely impervious to dust but any dust which does enter will not have any harmful effect on the equipment. The second digit (5) describes the level of protection from liquids. Water sprayed on the computer from all directions will have no harmful effect. Higher numbers indicate a higher tolerance to dust and water. For example, a unit with an IP65 certification will withstand exposure to dust and water better than a unit with an IP54 certification.
