Specification for degrees of protection provided by enclosures.
The IP number consists of two numbers, the first of which
describes the protection against solid bodies, and the
second describes the protection given against liquids.
ie for you QUE:

IP55-Enclosure provides protection from harmful levels of
dust and provides protection from low pressure water jets.

IP65-Enclosure provides total protection from dust and
provides protection from low pressure water jets

IP Enclosures
At Nema Enclosures, we strictly adhere to the International
Electrotechnical Commission standardized international (or
Ingress) Protection Code, which defines an enclosure's
rating. The IP Code reflects the degree of protection
as "IP" followed by two numbers. The first digit ranges
from 0 to 6, reflecting in degrees the level of protection
against particles, and protection to others from enclosed
hazards. The second digit ranges from 0 to 8 and indicates
the extent of protection against water. Because our
enclosures stringently observe these guidelines, you can
expect superior enclosures that are available in a number
of materials and types, and can be enhanced by our value
added services.
