IP Protection

IP stands for International Protection, the IP degrees of protection of electrical equipment against penetration by solid foreign matter, including dust and water. The exact degree of protection is achieved by various tests.

e.g. The IP rating of the 8517 series deck floodlight is listed as IP 6K 9K.
This means dust tight and protected from high pressure cleaning.

IP 6K 9K
First numeral= Protection against ingress of solid foreign objects (table 1)
Second numeral= Protection against ingress of water (table 2)

Table 1
Protection against the ingress of solid foreign objects (including dust)
X………..not tested
0………..not protected
1………..Solid foreign objects >50mm
2………..Solid foreign objects >12.5mm
3………..Solid foreign objects >2.5mm
4………..Solid foreign objects >1.0mm
5 and 5K..dust protected
6 and 6K..dust tight

Table 2
Protection against ingress of water
X……….not Tested
0……….not protected
1……….vertical dripping
2……….dripping (inclined 15 degrees)
3……….spraying
4……….splashing
4K………same with increased pressure
5……….jetting
6……….powerful jetting
6K………sames as increased pressure
7……….temporary immersion
8……….continuos immersion
9K………high pressure/steam jet cleaning
