What is IP Rating?


The resistance offered by the fixture to the penetration of solids and liquids is indicated by the IP (Ingress Protection) rating.


This is a two digit number, the first number identifies the degree of protection against the ingress of solids;

the second number against liquids

e.g. IP65 indicates total protection against dust and protection against low pressure jets of water.


First Digit

Protection against solids

0 No protection

1 Protected against solid objects greater than 50mm

(e.g. accidental contact with the hand)

2 Protected against solid objects greater than 12mm

(e.g. accidental contact with finger)

3 Protected against solid objects greater than 2.5mm

(e.g. tools and wires)

4 Protected against solid objects greater than 1mm

(e.g. fine tools and wires)

5 Protected against dust

6 Total protection from dust


Second Digit

Protection against liquids

0 No protection

1 Protection against vertical water drops

(e.g. condensation)

2 Protection against direct sprays of water, up to 15° from vertical

3 Protection against direct sprays of water, up to 60° from vertical

4 Protection against water spray from all directions

5 Protection against low pressure jets of water from all directions

6 Protection against jets of water of similar force to heavy seas

7 Protection against immersion between 15–100cm

8 Protection against submersion
