Ingress protection of Equipments

Ingress Protection Rating is assigned to enclosures for degree of protection provided by them

The Ingress Protection rating normally has two numbers:-

1. Protection from solid objects or materials

2. Protection from liquids (water)

Ingress Protection First number - Protection against solid objects:-

0	No special protection
1	Protected against solid objects up to 50 mm, e.g. accidental touch by persons hands.
2	Protected against solid objects up to 12 mm, e.g. persons fingers.
3	Protected against solid objects over 2.5 mm (tools and wires).
4	Protected against solid objects over 1 mm (tools, wires, and small wires).
5	Protected against dust limited ingress (no harmful deposit).
6	Totally protected against dust.

Ingress Protection Second number - Protection against liquids

1	Protection against vertically falling drops of water e.g. condensation.
2	Protection against direct sprays of water up to 15o from the vertical.
3	Protected against direct sprays of water up to 60o from the vertical.
4	Protection against water sprayed from all directions - limited ingress permitted.
5	Protected against low pressure jets of water from all directions - limited ingress.
6	Protected against temporary flooding of water, e.g. for use on ship decks - limited ingress permitted.
7	Protected against the effect of immersion between 15 cm and 1 m.
8	Protects against long periods of immersion under pressure.

e.g.

A motor having Ingress Protection of IP 65 is protected from:-
1. Total Protected from Dust
2. Protected against low Pressure jets of water from all directions i.e. limited Ingress

Now days Samsung has launched Smartphone S8 which is IP68 complied this means phone is Totally protected against dust and has protection against long periods of immersion under pressure.
