International Protection

IP Standards are a good way to compare the dust and water protection levels of different tools. “IP�? stands for Ingress Protection (An enclosure spec) or International Protection. The IP codes are normally two digit codes, such as IP65 or IP54. The first digit - tells the amount of foreign objects (or dust) that can enter the enclosure. The second digit - tells how watertight the enclosure is. As shown in the table below, the water protection spec is a good gage of how a tool will hold up against coolant spray on a machine tool.

Protection Level	Protection against human touch and foreign matter		Protection against water
	Type	Description	Type	Description
4	-	-	Splash-proof type	Has no harmful effect from water splashes coming from any direction
5	Protection against dust	Protection against harmful dust (penetration of dust not affecting the function is considered OK.)	Jet-proof type	Has no harmful effect from direct water jets coming from any direction
6	Dust sealing	Protection against the penetration of dust and perfect protection against human touch	Water-resistant type	Letting no water in from direct water jets coming from any direction
7	-	-	Watertight type	Letting no water in under specified conditions if submerged
