IP Ratings Table

Water-dust IP/ NEMA Resistant Technology
IP sealing is needed in various applications to make the products sealed against liquids, dust or humidity.
Certain computer manufacturers provide various levels of mechanical IP / NEMA dust, water and chemical resistant designs to offer ruggedized computers in the form of industrial flat panel LCD displays, panel PC and fanless computers. These ruggedized computer products are also designed for high reliability, shock and vibration tolerance, survival of high temperature, and corrosive environments. External contaminants can be very destructive to any type of computing hardware over time. The IP / NEMA rating provide standards towards the survivability of the computing hardware.

Table of NEMA Enclosure Rating and Comparison to IP Code

NEMA Enclosure Rating Description IP Classification Code
1 NEMA 1 – Enclosures constructed for indoor use to provide a degree of protection to personnel against incidental contact with the enclosed equipment and to provide a degree of protection against falling dirt. IP20
2 NEMA 2 – Same as NEMA 1 including protection against dripping and light splashing of liquids. IP21
3 NEMA 3 – Enclosures constructed for either indoor or outdoor use to provide a degree of protection to personnel against incidental contact with the enclosed equipment; to provide a degree of protection against falling dirt, rain, sleet, snow, and windblown dust; and that will be undamaged by the external formation of ice on the enclosure. IP54
3R NEMA 3R – Same as NEMA 3 excluding protection against windblown dust IP24
3S NEMA 3S – Enclosures constructed for either indoor or outdoor use to provide a degree of protection to personnel against incidental contact with the enclosed equipment; to provide a degree of protection against falling dirt, rain, sleet, snow, and windblown dust; and in which the external mechanism(s) remain operable when ice laden. IP54
4, 4X NEMA 4 – Enclosures constructed for either indoor or outdoor use to provide a degree of protection to personnel against incidental contact with the enclosed equipment; to provide a degree of protection against falling dirt, rain, sleet, snow, windblown dust, splashing water, and hose-directed water; and that will be undamaged by the external information of ice on the enclosure.

NEMA 4X – Same as NEMA 4 including protection against corrosion.

IP56, IP65, IP66
5 NEMA 5 – Enclosures constructed for indoor use to provide a degree of protection to personnel against incidental contact with the enclosed equipment; to provide a degree of protection against falling dirt; against settling airborne dust, lint, fibers, and to provide a degree of protection against dripping and light splashing of liquids. IP52
6,6P NEMA 6 – Enclosures constructed for either indoor or outdoor use to provide a degree of protection to personnel against incidental contact with the enclosed equipment; toprovide a degree of protection against falling dirt; against hose-directed water and the entry of water during occasional temporary submersion at a limited depth; and that will be undamaged by the external formation of ice on the enclosure.

NEMA 6P – Same as NEMA 6 including protection against the entry of water during prolonged submersion at a limited depth.

IP67
12, 12K NE1V1A 12 – Enclosures constructed (without knockouts) for indoor use to provide a degree of protection to personnel against incidental contact with the enclosed equipment; to provide a degree of protection against falling dirt; against circulating dust, lint, fibers, and against dripping and light splashing of liquids.
NEMA 12K – Same as NEMA 12 including enclosures constructed with knockouts
IP52
13 NEVA 13 – Enclosures constructed for indoor use to provide a degree of protection to personnel against incidental contact with the enclosed equipment; to provide a degree of protection against falling dirt; against circulating dust, lint, fibers, and against the spraying, splashing, and seepage of water, oil, and non-corrosive coolants. IP54
