IP Rating
An IP rating is a two-digit code that shows how well a device resists dust and water in set laboratory tests.

An IP rating, short for Ingress Protection, is a two-digit code defined by an international standard. It states how well an enclosure keeps out solid objects such as dust, and liquids such as water. IP67 and IP68 are common examples.
What the digits mean
- First digit, 0 to 6: protection against dust and solid objects. A 6 means dust-tight.
- Second digit, 0 to 9: protection against water. A 4 covers splashes, a 7 covers dips in still fresh water for up to 30 minutes at one metre, and an 8 covers longer or deeper immersion, as set by the maker.
- An X in place of a digit means that type of protection was not tested.
How it is tested
Laboratory tests use still, fresh water at a set depth and time, with the device new and undamaged. The code comes from the IEC 60529 standard, so the same letters mean the same thing for every maker.
What it does not promise
A rating is not a guarantee of lasting protection. Sea water, soapy water, hot water, steam and strong jets are outside the standard test, and seals wear down with age, drops and repairs. Brands in India generally do not cover liquid damage under the standard warranty, even for rated products.
