What are “IP Ratings”?
“IP” stands for Ingress Protection. The numbers determine how well a product is resistant to solid objects, and liquids. The first digit ranges 0-6 and the second ranges from 0-8. Each digit represents the degree of protection against one of the environmental factors. The first number relates to solid particle ingress and the second to fluid ingress. An ‘X’ can be substituted for one of the digits if there is only one class of protection. Below shows the significance of the numbers.
