The IP certification provides information about the external influences against which an industrial computer (or electrical devices in general) is protected. This includes protection against intrusion, contact, liquids and dust. IP” stands for “International Protection Codes”.

While the IP codes meanwhile represent an international standard, there is still no uniform standard for the test procedures and thus a not inconsiderable scope for interpretation in the respective protection classes. Many providers claim to guarantee a certain IP protection, but this is mostly based only on internal tests and without evidence from certified test centers.
