 IP - Ingress Protection

 

This article summerizes a combination of IEC 60529, EN 60529, ISO 20653 and others. Each digit or part of the IP code represents:

IPXx   1st characteristic Solid particle protection
IPxX    2nd characteristic Liquid ingress protection

 

 

 


1st digit

Solid particle protection

 

IP0x

No Protection

 

IP1x

IP1x

>50.0mm

Protected against objects greater than 50mm diameter

IP2x

Dust protected

Ingress of dust is not totally prevented but dust does not enter in harmful quantities to interfere with the correct operation or impair safety

IP6x

IP6x

Dust tight

No ingress of dust permitted

 


2nd digit

Liquid ingress protection

 

IPx0

 

No Protection

 

 

IPx1

Image
IPx1

Volume: Ø1mm rainfall

Vertically falling waterdrops
Duration: 10 minutes

IPx2

Image
IPx2

Volume: to 3mm rainfall per minute

Vertically falling waterdrop, tilted 15°.
Duration: 2,5 minutes for every direction of tilt (10min. total)

IPx3

Image
IPx3

Volume: 10 liter per minute

Sprays at any angle up to 60°.
Duration: 1 minute met m³ for 5 minutes

IPx4

Image
IPx4

Volume: 10 liter per minute

Water splashed from all directions.
10 minutes, oscillating tube    

IPx5

Image
IPx5

Volume: 12,5 liter per minute (30kPa)

A 6.3mm nozzle from any direction.    

IPx6

Image
IPx6

Volume: 100 liter per minute (100kPa)

No ingress of water permitted

 

IPx7

Image
IPx7

30 minutes

Temporary submersible at minimal 15cm up to 1 meter depth for at east 30 minutes.    

IPx8

Image
IPx8

To be agreed with manufacturer    

Immersion, 1 meter depth or more, specified by manufacturer.    

IPx9

Image
IPx9

80°C - 14-16 liter per minute
(8-10MPa - 80-100 bar)

High temperature, high pressure water and steam.

 

 Curiously, IPx7 and IPx8 do not “stack” with lower ratings. So a product that’s IPX7 or IPX8 rated can live underwater for a while but might still get damaged by a spray of water from the side and vice versa. If a product can survive both scenarios, it gets a dual rating – e.g. IPx6/IPx8.

 

 IK - Impact Protection

 

IK Rating or “Impact Protection” (the K is from ‘Kinetic’ to differentiate from IP rating) are an international numeric classification to indicate the degrees of protection provided by enclosures for electrical equipment against external mechanical impacts. It provides a means of specifying the capacity of an enclosure to protect its contents from external impacts in accordance with IEC 62262:2002 and IEC 60068-2-75:1997.
