Water Ingress

 

PTI provides Water Ingress testing, which is usually the second part of ingress protection (IP) specified in IEC 60529. The second characteristic numeral (such as IPx4) describes the degree of protection against ingress of water with harmful effects.

Table 1: Brief Explanation of IP Code

IP Code Description
Water Ingress IP x0 Non-protected
IP x1 Protected against vertically dropping water drops
IP x2 Protected against vertically dropping water drops, when enclosure is tilted up to 15°
IP x3 Protected against spraying water
IP x4 Protected against splashing water
IP x5 Protected against water jets
IP x6 Protected against powerful water jets
IP x7 Protected against the effects of temporary immersion in water
IP x8 Protected against the effects of continuous immersion in water
Ingress of Solid Foreign Objects IP 0x Non-protected
IP 1x Protected against solid foreign objects of 50mmØ and greater
IP 2x Protected against solid foreign objects of 12.5mmØ and greater
IP 3x Protected against solid foreign objects of 2.5mmØ and greater
IP 4x Protected against solid foreign objects of 2.5mmØ and greater
IP 5x Dust protected
IP 6x Dust tight
