EN 60529 Testing

EN 60529 is also known as the IP Code or Ingress Protection Rating and sometimes also referred to as the International Protection Rating. The IP Code consists of the letters “IP” and then either two digits or one digit and one letter and an optional letter. IP Code classifies and rates the degrees or protection provided against the intrusion of solid objects of dust, water and accidental contact within mechanical castings and electrical enclosures.The first digit indicates the level of protection that the enclosure provides against access to hazardous parts and the ingress of solid foreign objects.

Level
Object size protected against
Effective against
0
No protection against contact and ingress of objects
1
>50 mm
Any large surface of the body, such as the back of a hand, but no protection against deliberate contact with a body part
2
>12.5 mm
Fingers or similar objects
3
>2.5 mm
Tools, thick wires, etc.
4
>1 mm
Most wires, screws, etc.
5
Dust protected
Ingress of dust is not entirely prevented, but it must not enter in sufficient quantity to interfere with the satisfactory operation of the equipment; complete protection against contact
6
Dust tight
No ingress of dust; complete protection against contact

 

The second digit indicates the level or protection that the enclosure provides against access to hazardous parts and the ingress of water.

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

Test duration: 10 minutes

Water equivalent to 1mm rainfall per minute

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

Test duration: 10 minutes

Water equivalent to 3mm rainfall per minute

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

Test duration: 5 minutes

Water volume: 0.7 litres per minute

Pressure: 80–100 kN/m²

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

Test duration: 5 minutes

Water volume: 10 litres per minute

Pressure: 80–100 kN/m²

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

Test duration: at least 3 minutes

Water volume: 12.5 litres per minute

Pressure: 30 kN/m² at distance of 3m

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

Test duration: at least 3 minutes

Water volume: 100 litres per minute

Pressure: 100 kN/m² at distance of 3m

7
Immersion up to 1 m
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).

Test duration: 30 minutes

Immersion at depth of 1m

8
Immersion beyond 1 m
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.

Test duration: continuous immersion in water

Depth specified by manufacturer

 

The IP Code defines additional letters that can be appended to classify only the level or protection against hazardous parts by persons or additional information related to the protection of the device:
A – Back of hand
B – Finger
C – ToolD – Wire
H – High voltage device
M – Device moving during water test
S – Device standing still during water test
W – Weather conditions

Mechanical Impact Resistance numbers are sometimes used to identify the energy needed to qualify a specified resistance level, which is measured in joules (J). It is important to note that mechanical impact resistance was dropped from the third edition of IEC 60529 onwards.
