Two digits for dust and water.
Also known as: Ingress protection rating, IP code
The two-digit code stating how far an enclosure keeps out solid objects and water.
States an enclosure's protection against solid objects and against water, by two digits in fixed positions.

The two digits are independent scales, so a higher second digit does not imply the first — and the X substitution exists because a product may be tested for one and not the other.

The water scale is not cumulative at its upper end: immersion ratings and jet ratings test different things, so a rating for immersion does not guarantee performance against a jet.
Upper water-protection levels are not cumulative; a higher digit does not include every lower test.

The letters IP followed by two digits, the first for solid objects and the second for water, with an X standing in where a figure is not rated.
