2.2 Ingress Protection IP67
IEC International Standard 60529 (Edition 2.1: 2001-02) is a "classification of degrees of protection
provided by enclosures as a system for specifying the enclosures of electrical equipment on the
basis of the degree of protection provided by the enclosure." These ratings are determined by
specific tests
The IP number is composed of two numbers, the first referring to the protection against solid
objects and the second against liquids. The higher the IP number, the better the protection. The
chart below defines levels of IP ratings.
