The Ingress Protection (IP) rating system defined in standard IEC 60529 (specifically, the second numeral related to water, as depicted in Figure 1) offers an indicative guide to identify the environment referred to in the above-mentioned criteria. Nevertheless, an IP rating grades resistance of an enclosure against the intrusion of dust or liquids; it is not limited only to appliances that operate in a certain primary environment for a given part of their active service, nor does it establish whether redesign is possible or not. As such, the IP rating alone is considered as sufficient to demonstrate the compliance with the above-mentioned criteria.
