The IP rating of a product is often listed in a format such as “IP67”, but often what this actually means can be ambiguous.
The first number is the level of protection against solids, the second number is the level of protection against liquids. Taking the example above, IP67 would mean that the item is dust tight and resistant to temporary submersion in water.
Below shows each rating and what this means.
|Solids Protection||Size of Particule||Liquid Protection||Volume of Water|
|0||No Protection||0||No protection|
|2||>12.5mm||2||Water drops at 15 degree angle|
|3||>2.5mm||3||Water spray at 60 Degree Angle|
|4||>1.0mm||4||Water splashing at any angle|
|5||Dust Protected||5||Water jets at any angle|
|6||Dust Proof||6||Powerful water jets and heavy seas|
|7||Temporary submersion in water (30 minutes at 3 feet)|
|8||Permanent submersion (Up to 13 feet)|
