IP68: Definition, Comparison, and Classifications


IP is truncated to protect against advancement. The source is IEC 60529 of the International Electrotechnical Commission standard, which in 2004 was accepted as the American national standard. An IP is an international code used to identify the level of protection.

The IP level consists of two numbers. The first number indicates dust resistance; The second number indicates the water resistance, the higher the number, the better the team’s length.

The appropriate test bases in China are the requirements of GB standard “4208-2008 / IEC 60529-2001” Degree of protection of the enclosure (IP code), “conformity assessment test for the degree of protection of the compound various products; the highest degree of detection IP68, IP54, IP55, IP65, IP66, IP67, IP68.

You will often see products with more than one IP rating, and that is because they have been tested on different types of waterproofing. For example, the Sony Xperia Z5 has an IP68 and IP65 protection rating.

As already mentioned, an IP68 rating means that it can survive submerged. IP65 indicates that it is also suitable for spraying management.

It has been tested with water with a 6.3 mm nozzle. However, in actual use, it merely means that it can survive rain or a shower. Do not spray it under pressure.

If you see an older device with IP53, it means that it is a little dustproof but not entirely and can live on water jets, but no water jokes and indeed no immersion.

Definition of IP68

IP68 is the highest level of water resistance of the connection.

Everyone look at the waterproof performance of the waterproof connector, mainly at the two digits XX behind IPXX, the first digit X is 0 to 6, the highest level is 6; the second digit X is between 0 and 8, the highest level 8; therefore, the highest rating of the terminal seal is IP68. In other words, the IP68 port is a high-level waterproof port.

There are many results in the market which claim that the water resistance of the connector reaches IP68.

In the strict sense of the term, IP68 connection with excellent sealing properties and safe and reliable quality is still rare.

The IP68 test standard for certain brands is: put the connection product in a water depth of 10 meters, work for two weeks; Set the water depth to 100 meters; a 12-hour damage test can still maintain excellent product performance.

IP67 vs. IP68: which device is best for you?

If you are fighting between IP67 and IP68, you will be happy to know that both devices will have complete dust resistance.

The IP67 device supports up to 1 m of water for 30 minutes. For a device with an IP68 protection rating, in addition to dust resistance, it will also use full immersion in more than one meter of water for a period specified by the device manufacturer.

The difference comes down to exposure to water. Samsung Galaxy S9 + has an IP68 protection rating, which, according to Samsung, protects against immersion in 1.5 mm of water for 30 minutes without the case and other accessories.

More and more device manufacturers incorporate some form of dust and water resistance, which is a welcome change. Still, you don’t want to throw your phone into a nearby pond just for fun.

Many phones, smartwatches, and other devices contain some form of protection from the elements.

  • IP67: for dust-resistance and protection of 1 m of water for 30 minutes
  • IP68: for dust-resistance and stability of 1.5 m of water for 30 minutes (may vary depending on the manufacturer

IP67 Vs. IP68: What do IP Classifications Mean?

However, it should be well-known that there is a difference between water resistance and waterproof.

Water-resistance means something is waterproof no matter how long it has been inundated; waterproof means that the product can, to some extent, prevent water from entering, but not completely.

When it comes to smartphones and smartwatches, it’s almost always about their water resistance. It cannot survive indefinitely in the water.

IP is the name of a standard developed by the International Electrotechnical Commission (IEC) to determine the resistance of electrical appliances to freshwater and conventional raw materials, such as dirt, dust, and sand.

The first number after IP is the IEC rating assigned to the unit due to resistance to solids. There are six, which means that no “harmful” dirt or dust has entered the device after eight hours of direct contact with the installation.

IP67 Vs. IP68: Can I Swim with a Smartphone?

We certainly do not recommend swimming by phone. When IEC tests a smartphone, it does it in a laboratory, with the phone on standby, rather than in a pool filled with various chemicals used to purify water.

The same goes for the ocean. The seawater is full of salt, the stress of the manufacturer of the mineral device is not tested during the test of the unit’s IP index, so we strongly recommend that you avoid it.

In 2015 Sony released promotional photos showing the new IP68 certified Xperia phone used to take underwater photos. He then controversially changed his point of view, warning customers not to use the device underwater.
