IP (Ingress Protection) is a system for numerical classification of the degree of protection provided by an enclosure.
The 1st digit (example: IP6_) indicates the degree of protection against dust (6 means completely protected against dust, as set out
in the table below)
The 2nd digit (example: IP_5) indicates the degree of protection against ingress of water (5 means protected against jet water, as
set out in the table below)
