It’s 2019 and most of the phones are water resistant, but few phones in the markets are waterproof also. Now.. if a manufacturer says that the phone is waterproof it does not meet that you can now keep your phone underwater forever.
Now, coming to the title of the Post.. you read IP Rating…What is IP Rating?
What is IP Rating?
The IP Code, International Protection Marking, IEC standard 60529, sometimes interpreted as Ingress Protection Marking, classifies and rates the degree of protection provided against intrusion, dust, accidental contact, and water by mechanical casings and electrical enclosures.
In this era for most of the phones, they accompany an IP rating. An IP Rating is described by IP and followed by two number for example IP67.

Why IP Rating system is required?
The need for having a universal IP rating system is so that the buyers, tech people, and other users can be confident of how safe it is to use certain electrical or mechanical goods in specific environments and applications.
Unlike more vague marketing terms such as ‘waterproof’ – which don’t necessarily give a clear definition of precisely where and to what extent an item can resist moisture ingress – an IP rating is designed to provide a far more specific account.
If IP Rating is not established and companies just advertise a product saying it’s waterproof then people would try to use it as an actual waterproof device and may use it in water which would lead to permanent damage of the phone.
What is the significance of IP Rating syntax?
The two digits represent different forms of environmental influence:• The first digit represents protection against ingress of solid objects.• The second digit represents protection against ingress of liquids.
The larger the value of each digit, the greater the protection.
IP RATING TABLE
| IP Rating
|
First digit: Ingress of solid objects |
Second digit: Ingress of liquids |
|---|---|---|
| 0 | No protection | No protection |
| 1 | Protected against solid objects over 50mm e.g. hands, large tools. | Protected against vertically falling drops of water or condensation. |
| 2 | Protected against solid objects over 12.5mm e.g. hands, large tools. | Protected against falling drops of water, if the case is disposed up to 15 from vertical. |
| 3 | Protected against solid objects over 2.5mm e.g. wire, small tools. | Protected against sprays of water from any direction, even if the case is disposed of up to 60from vertical. |
| 4 | Protected against solid objects over 1.0mm e.g. wires. | Protected against splash water from any direction. |
| 5 | Limited protection against dust ingress. (no harmful deposit) |
Protected against low-pressure water jets from any direction. Limited ingress permitted. |
| 6 | Totally protected against dust ingress. | Protected against high-pressure water jets from any direction. Limited ingress permitted. |
| 7 | N/A | Protected against short periods of immersion in water. |
| 8 | N/A | Protected against long, durable periods of immersion in water. |
| 9k | N/A | Protected against close-range high pressure, high-temperature spray downs. |
Apart from this rating, there is one additional rating also
Additional protection designation
| Letter code | What it means |
| f | Oil resistant |
| H | High voltage protection |
| M | Motion during any testing |
| S | No motion during any testing |
| W | Weather resistant |
Though this rating is not mentioned by the manufacturers or on the box it is good to know for yourself.

Final Words
It is very important for every gadget or smartphone user to know about IP Rating of their current phones so that they know the limitations and the features of their phones and to what limit their device is vulnerable to external forces.
