Today we're going to look at IP levels.

Time: 2019-03-18

IP (or "Ingress Protection") ratings are defined in international standard EN 60529 (British BS EN 60529:1992, European IEC 60509:1989). They are used to define levels of sealing effectiveness of electrical enclosures against intrusion from foreign bodies (tools, dirt etc) and moisture.

What do the numbers in an IP Rating mean?

The numbers that follow IP each have a specific meaning. The first indicates the degree of protection (of people) from moving parts, as well as the protection of enclosed equipment from foreign bodies. The second defines the protection level that the enclosure enjoys from various forms of moisture (drips, sprays, submersion etc).

First Digit: Solids

The first digit indicates the level of protection that the enclosure provides against access to hazardous parts (e.g., electrical conductors, moving parts) and the ingress of solid foreign objects.

1. No special protection<

2. Protection from a large part of the body such as a hand (but no protection from deliberate access); from solid objects greater than 50mm in diameter.

3. Protection against fingers or other object not greater than 80mm in length and 12mm in diameter.

4. Protection from entry by tools, wires etc, with a diameter of 2.5 mm or more.

5. Protection against solid bodies larger than 1mm (eg fine tools/small etc).

6. Protected against dust that may harm equipment.

7. Totally dust tight.

Second Digit: Liquids

Protection of the equipment inside the enclosure against harmful ingress of water.

0. No protection.

1. Dripping water (vertically falling drops) shall have no harmfull effect.

2. Vertically dripping water shall have no harmful effect when the enclosure is tilted at an angle up to 15° from its normal position.

3. Water falling as a spray at any angle up to 60° from the vertical shall have no harmful effect.

4. Water splashing against the enclosure from any direction shall have no harmful effect.

5. Water projected by a nozzle (6.3mm) against enclosure from any direction shall have no harmful effects.

6. Water projected in powerful jets (12.5mm nozzle) against the enclosure from any direction shall have no harmful effects.

7. Ingress of water in harmful quantity shall not be possible when the enclosure is immersed in water under defined conditions of pressure and time (up to 1 m of submersion).

8. The equipment is suitable for continuous immersion in water under conditions which shall be specified by the manufacturer. Normally, this will mean that the equipment is hermetically sealed. However, with certain types of equipment, it can mean that water can enter but only in such a manner that it produces no harmful effects.

Our range

IP65 Enclosure - IP rated as "dust tight" and protected against water projected from a nozzle.

IP66 Enclosure - IP rated as "dust tight" and protected against heavy seas or powerful jets of water.

IP 67 Enclosures - IP rated as "dust tight" and protected against immersion.

IP 68 Enclosures - IP rated as "dust tight" and protected against complete, continuous submersion in water.
