Summer is coming and it is more than possible that we have the bad luck of having an occasional water accident with our smartphone. The most protected devices in this aspect are the IP68 , how can it be Galaxy S9 , although there are also terminals with somewhat less protection, such as IP67 of the Huawei P20 Pro . Today we explain the water resistance of your smartphone very easily.
As you know, some manufacturers add a IP certification in their devices to announce some degree of protection against dust and water, but few people know exactly what conditions imply the IP numbers of our smartphones.
First of all, we should know that IP certification is synonymous with International Protection, and implies that a device is capable of withstanding certain environmental conditions according to the protection standard IEC 60529, for which a series of definite and quite exhaustive tests must pass.
Protection against dust: the first number
When we see an Ip certification, the first number refers to the ability of our smartphone to prevent the entry of objects inside, with 0 being zero protection and 6 the maximum protection, even against dust. This is what each number means:
- 0. Without protection
- 1. An object less than 50mm can not enter the device.
- 2. An object less than 12.5mm is not able to enter the device.
- 3. Our smartphone can prevent the entry of objects less than 2.5mm in size
- 4. We are protected against objects less than 1mm
- 5. It may be dust, but it will not affect the operation of our smartphone.
- 6. Our smartphone is asiled against dust.
As expected, only the last two numbers they are interesting when deciding to buy a smartphone, since other larger objects will hardly have the possibility to penetrate inside the device.
Protection against water: the second number
We are going with what you are most interested in facing this summer, the water resistance of your smartphone. As with the dust resistance, we have a Numerical scale that tells us the tests that a device has passed, but beware, that each number does not have to include the previous certification, and therefore, an IP68 certificate could not support the tests of number 5, to give an example.
This is the explanation for the water resistance of your smartphone:
- 0. It has no protection against water.
- 1. Includes light protection against splashes.
- 2. Light protection against splashes coming from any direction.
- 3. Protection against water sprayed with spray.
- 4. Protection against water jets with a flow of 10l per minute with a pressure of 80-100kN / m ^ 2 for 5 minutes.
- 5. Protection against water jets with a diameter of 6.3mm and a flow rate of 12.5l per minute with a pressure of 30kN / m ^ 2.
- 6. Protection against jets with an average flow rate of 100l per minute and a pressure of 30kN / m ^ 2
- 7. Resistance to a complete immersion of less than one meter deep for 30 minutes.
- 8. Complete protection to a degree set by the manufacturer, but above level 7
- 9K. Device with protection against very powerful jets and at high temperatures.
If we look at the smartphone field, the numbers 7 and 8 are the ones that interest us most, since it is practically impossible for our smartphone to be subjected to some of the above conditions (beyond the spray), but we must take into account one very important thing, this scale it only works with fresh water , so our smartphone is vulnerable to the salt water of the beaches (and some swimming pools), so be very careful before throwing your head towards the waves with your mobile in your pocket, we can spoil the holidays, never better.
