How resistant to water and dust is my phone? Guide with all the certifications: IP69, IP68, IP67 …

25 mayo, 2021

It was 2013. Sony, the well-known Japanese company, launched the Sony Xperia Z, a high-end device that stood out, mainly, for being water and dust resistant. Since then, IP certifications have become the order of the day and are an element that we see in almost all mid-range and high-end devices. There are them of different levels and today we are going to know them all.

When we talk about IP certification (Ingress Protection) we always put a surname made up of two numbers, usually IP68 or IP67 and, more recently, IP69. They are not random numbers. The first of these represents resistance to ingress of dust on a scale of six, while the second is resistance to water on a scale of nine. As you may have guessed, more is better. All this is collected in the international standard IEC 60529 Degrees of Protection.

Dust resistance

We start with the solid elements and it is important to make one thing clear: Dust resistance does not measure scratch resistance. That your mobile has IP6X certification does not mean that it cannot suffer damage to the screen, but elements of more than a certain diameter cannot penetrate.

These are the tests that mobiles have to pass to be IP68

To determine the degree of resistance, the device is subjected to a series of tests that it has to withstand. Depending on the hardness of the test and of what resists, one or the other “score” is awarded. In the case of dust, the scale is over six, with six being the greatest protection and zero being the least.

4

You must not enter.

Dust

Dust can enter, but in amounts that do not affect the operation of the device

6

Dust

Dust cannot enter and the device is completely watertight

As you can see, the device that has IP6X certification is completely waterproofthat is, the dust cannot even enter. For context, if we stick to the granulometric definition in the International System, a grain of coarse sand is between 0.5 and 2 mm in diameter and a grain of fine sand is between 0.05 and 0.2 mm in diameter. diameter.

Waterproof

Water

In the case of resistance to liquids, the standard uses different water flows in different conditions. These range from a drip to a jet under pressure at high temperatures. Unlike dust resistance, water resistance is measured on a scale of nine. Again, more is better.

Indeed, a device with IPX9K certification It’s very tough. The CEI 60529 certification does not contemplate it, but is defined by the German standard DIN 40050-9 as an extension of the first. To give you an idea of ​​what this certification means, it is the one that has the boxes designed for the pharmaceutical or food industry.

Unless you usually pressure wash your mobile in a car wash, it is normal that you take advantage of this certification in those places where the mobile runs the risk of getting sand or getting wet, that is, the beach and pool.

To avoid risks, the ideal is that the mobile has IP68 certification. If you take a look at the table, you will see that this means that it is completely dust-tight (and sand, of course) and that it can be submerged for a minimum of thirty minutes to a minimum depth of one meter.

Now, the fact that the mobile has IP certification does not mean that it is covered by the official manufacturer’s warranty. In fact, most establish in their policies that they do not cover damage caused by water or improper use. Keep this in mind when putting your phone under the water to take a photo in the pool.
