Explained: What is IP rating and what does IPX5, IP68 rating mean for Smartphones, Earphones, Smartwatches?

IP55, IP65, IP67, IP68, ipx5etc are words with which you are often found associated Smartphones, smartwatch And earphones, If you’re not aware, IP Rating Device Defines how well your device is protected from water and dust.
But what are these numbers and what do they mean? How do each IP rating differ and what do they actually mean for your devices? Let’s explain.
What is IP Rating?
IP rating means ingress protection. It is a universally accepted measure of protection against dust and water. The IP rating of a device basically defines how well the electrical housing inside the device can prevent dust and water from entering.
Are IP Rated Devices Completely Secure?
No, an IP rating simply reflects how much protection a body can provide. However, this does not mean that the device will never deteriorate. In addition, there are different IP ratings that provide more or less protection. For example, a device rated IP68 is relatively more secure than a device that comes with an IP55 rating.
Also, it is important to note that the term used here is water and dust. This means that the protection offered here is not for other liquids like coffee, wine, seawater, etc.
How does a device get an IP rating?
As mentioned, the IP rating is a standard measure of protection against water and dust. These ratings are standardized by the International Electrotechnical Commission (IEC). To obtain IP certification for a device, the device undergoes a series of laboratory tests and then rates a device.
Different IP Ratings and What They Mean
For starters, an IP rating consists of two numbers IP68, IPX8, IP67, etc. The first number represents dust and particulate protection and 6 is the maximum rating a device can achieve on a scale of 0 to 6. If a device gets a rating of 0 then an X is given to it.
The second digit represents water resistance and is measured between 0 and 8. This means that IP68 is the maximum that a device can achieve.
Here is a list of common IP ratings and their meanings
IP68: The IP68 rating means a device can survive up to 30 minutes in dust and 1.5 meters of water.
IP67: Provides protection against dust similar to IP68. However, in terms of water conservation, it is only safe to hold up to 1 meter of water for 30 minutes.
IP55: This rating is for sweat and dust protection only
IPX5: Not protected from dust, but offers modest protection from water
