Basics of...IP Standards

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.
