The protection rating is a determining indicator in the choice of your sound equipment. Depending on your needs, you must analyze the scale of protection ratings, which is relatively broad, in order to select the most effective material for the use of the loudspeaker (weather, vandalism).
The degree of protection of the enclosures of electrical equipment is defined according to the standards CEI 60529, EN 60529 and NF C 20-010.
In the table below you will find the first number which defines the degree of protection against accidental contact, foreign bodies and dust. The second number defines the degree of protection against water.
1st digit: | 2nd digit: Protection against liquids | ||||
Protection Rating | TESTS | Protection Rating | TESTS | ||
0 | No protection | 0 | No protection | ||
1 | Protected against solid objects larger than 50 mm (e.g. involuntary hand contact) | 1 | Protected against vertical drops of water (condensation) | ||
2 | Protected against solid bodies larger than 12.5 mm (e.g. finger of the hand) | 2 | Protected against falling water up to 15° from the vertical | ||
3 | Protected against solid objects larger than 2.5 mm (tools, screws) | 3 | Protected against rainwater up to 60° from the vertical | ||
4 | Protected against solids larger than 1 mm (fine tools, small wires) | 4 | Protected against water spray from all directions | ||
5 | Protected against dust (no harmful deposits) | 5 | Protected against water jets from all directions | ||
6 | Fully protected against dust | 6 | Fully protected against water splashes similar to sea spray | ||
