Tcca Ia Ingress Protection (IP Rating) Reference Chart In the latest standards SFS - EN 60529 4 1992 concerning the IP degrees of enclosure protection of electrical equipment there are some changes particularly with regard to the testing and identification of protection against liquids. Up to the degree 6 the protection is understood to also cover the lower protection degrees. In degrees higher than 6, each degree is to be tested separately and marked accordingly, e.g. IP67 / IP66.
