1st Digit	Protection	Explanation
0	No protection	-
1	Protection against large foreign bodies	Protection of persons from accidental large area direct contact with active or internal moving parts (e.g. hand contact), nut no guarding against intentional access to such parts. Protection of the object from access of solid foreign matter larger than Ø50mm.
2	Protection against medium-size foreign bodies	Protection of persons from finger contact with active or internal moving parts. Protection of the object from access of solid foreign matter larger than Ø12mm.
3	Protection against small foreign bodies	Protection of persons from contact with active or internal moving parts with tools, wires or similar foreign matter thicker than Ø2.5mm. Protection of the object from access of solid foreign matter larger than Ø2.5mm.
4	Protection against granular foreign bodies	Protection of persons from contact with active or internal moving parts with tools, wires or similar foreign matter thicker than > than Ø1mm.
5	Protection against deposits of dust	Total protection of persons from contact with voltage carrying or internal moving parts. Protection of the object from harmful deposits of dust. Ingress of dust is not completely prevented, but dust is prevented from entering in a quantity that would impair the functioning of the object.
6	Protection against ingress of dust	Total protection of persons from contact with voltage carrying or internal moving parts. Protection of the object from ingress of dust.

2nd Digit	Protection	Explanation
0	No protection	-
1	Protection against water dripping vertically	Water drops falling vertically must not have any harmful effect.
2	Protection against water dripping up to 15°	Water drops falling at any angle up to 15° from vertical must not have any harmful effect.
3	Protection against spray water	Water hitting the object at any angle up to 60° from vertical must not have any harmful effect.
4	Protection against splash water	Water splashing against the object from all directions must not have any harmful effect.
5	Protection against jet water	A jet of water nozzeled against the object from all directions must not have any harmful effect.
6	Protection against flooding	Water of temporary flooding, as in heavy seas, must not enter the object in any harmful quantity.
7	Protection against dipped state	If the object is dipped into water (150mm to 1000mm), under the defined conditions of pressure and time, water must not enter the object in any harmful quantity.
8	Protection during submerged state	If the object is submerged in water under defined extreme conditions, water must not enter the object in any harmful quantity.
