It is typically shown as IP54 or IP67 etc. An IP rating is a two-digit number established by the International Electro Technical Commission and is used to provide an Ingress Protection rating to a piece of electronic equipment or to an enclosure for electronic equipment. The first number is the object protection level; the second number is the moisture resistance level. The numbers range from 1-8 with 8 meaning better protection. In radio we only really see 4-8 mentioned. So, the higher the numbers you see, the better the protection level.
