Water and Dust Protection

Now consider this situation, you bought the top end smartphone giving a huge amount of money from your wallet. You might be very rich so it did not hit you hard but possibilities are that are you were on a tight budget and you bought the phone on EMI and when you were just ready to show off and bluff you mistakenly dropped your device into water. Unfortunately, your device wasn’t water resistant.


Talking about water and dust(solid) resistance, off late even the low budget smartphones are coming with little amount of dust(solid) and water resistance. The engineers have got really smart and they know the value of our hard earned money. So to prevent the devices from any mishap like the one which was mentioned above the devices are coming with Water and Dust (solid) resistance.

Further one should keep it really clear in mind that being dust and water resistant is different from being waterproof and dustproof.

So, Lets begin with it.

While seeking for dust and water resistant nature of a device, one should seek for the device’s IP rating. IP, which is just the acronym for Ingress Protection. Ingress is defined as “the action or fact of going in or entering” which clearly shows why the word Ingress is used in the scale. IP codes are a standard set forth by the International Electrotechnical Commission(IEC). According to the organization, the codes are designed as a “system for classifying the degrees of protection provided by the enclosures of electrical equipment.” Devices are provided with these kinds of resistances by using adhesives made of special resins.

The IP rating of a device looks something like this: “IPab

Here, “a” represents the dust resistance on a scale of 0 to 6 and “b” represents the water resistance on a scale of 0 to 8.

For example, IP68 means the device provides dust resistance of level 6 and water resistance of level 8.

Now an obvious question that would have came in your mind is what on earth are these different levels, for this refer the table below.

Various levels of the Dust (solid) and Water resistance



Since we took the example of IP68 earlier in the article lets build up our further understanding by actually understanding what is IP68!

So, as usual IP stands for Ingress Protection and here the value “6” means that the device is will be dust resistant if left in dust for 2 to 8 hours (from the table) and further the value “8” means that the device will not be harmed by water if immersed in it under pressure for long periods of times (from the table). Another important thing is that all the tests that had been carried out for knowing the water resistance took fresh water into account, not any sort of impure water.

That was the simplest explanation of what is dust (solid) and water resistance and I we hope you like it.
