IP ratings: Ingress Protection, International Protection or Internal Protection Rating refers to a set of international standard codes that marks the level of protection a phone/gadget gets to protect against environmental factors like moisture, dust and other solid/liquid intrusion.

It is identified by the letters IP followed by 2 numbers. The numbers help define the amount of protection a device has against intrusion of solid or liquid matter.

The first digit refers to solid matter such as dust, sand, specks, fingers, nuts etc that could get into a device and make it to fail.

The second digit refers to protection against liquid matter like moisture, water etc. The larger the numbers, the better protection a device offers.

In most water resistant smartphones and rugged devices, the IP Rating is used to level of protection the phone has to protect it from failing.

IP RATINGS FOR SOLID (FIRST DIGIT)

DIGITInterpretation
0No Protection
1Protection against solid objects greater than 50 mm such as the back of the hand.
2Protection against solid objects greater than 12 mm diameter suchas fingers or other similar objects.
3Protection against solid objects greater than 2.5mm diameter like thick wires.
4Protection against solid objects greater than 1.0mm diameter like screws.
5Dust protected but not entirely prevented. Though there is complete protection against contact
6Dust tight. No Ingress of dust. Device is completely sealed against dust.

IP RATINGS FOR LIQUID (SECOND DIGIT)

DIGITInterpretation
0No protection
1Vertically dripping water has not effect
2Protected against dripping/spraying water when tilted up to 15.
3Protection offered against direct sprays of water up to 60 degrees from the vertical
4Protected against water sprayed/splashes from all directions
5Water projected by a nozzle (6.3mm) against gadget from any direction shall have no harmful effects.
6Water projected in powerful jets (12.5mm nozzle) against the gadget from any direction shall have no harmful effects.
7Protection offered against the effects of immersion in water between 15 cm (5.9 inches) and 1 meter (3.3 feet) for up to 30 minutes
8Protection offered against the effects of immersion in water for long period in depths, under pressure or conditions specified by the manufacturer. In most cases, this means the device is either sealed airtight or can allow in water in quantities that cannot damage the device.
9KProtection offered against close-range high pressure, high temperature spray downs.

The above charts are used to check the level of protection a device has especially when it is said to be waterproof or water resistant by manufacturers. If a device has IP57 rating, it means it is “Dust protected” and “can survive submersion in water for not more than 30 minutes”.

WHAT IS IP69K RATING

Most charts found out there ends at IP68 (device is completely sealed against dust and protection is offered against the effects of immersion in water for long period) but there is an IP69K rating.

IP69K rating is used on equipments/gadgets that must withstand high pressure in environments that either require high level of sanitation or where dirt can be an issue. Recently, most smartphone manufaturers have started applying this rating on their devices too, mostly rugged devices.

IP Ratings does ensure peace of mind, knowing your device may not damaged if you picked it up with wet hands, get water on it or it even falls into a bowl of water. Nut take note that most of these tests are done in labs under controlled conditions and may nt be 100% reliable in real life scenarios,
