What is an IP68 rating?
At its most basic, IP68 is a protection rating against dust and water. The IP stands for Ingress Protection, whilst the first number refers to protection against solids, and the second number refers to protection against water. There are several different ratings, but IP68 is the most common in today’s market.
The Hard Bit.
The ‘6’ in IP68 means that the device can withstand small dust particles, including sand and dirt. So it’s perfect for the construction site or even at the beach.
The Wet Bit.
The last number is water protection. 8 means that it is tested to withstand temporary submersion in water up to 1.5 meters deep for 30 minutes. 9 means that the device is designed to withstand high-pressure jets of water from close range.
And remember to check the small print...
Many non-rugged phones are also rated IP68, but this can sometimes give users false confidence in their phone. Any drops or damage can make the IP rating void, so your waterproof phone might no longer be very waterproof.
