Consumer electronics is a category that consists of computer equipment, TVs, cameras, small home appliances, accessories, and much more. Especially in the case of mobile devices, it is important for consumers that they are resistant to water and dust. On the labels of smartphones, smartwatches, sports cameras, or headphones, you can find markings such as IP68 and IP69. What do they actually mean, and how do they differ?
What does the IP protection class mean?
The IP protection class (ingress protection) is an international standard that specifies the level of protection of electronic devices against the penetration of solid objects, such as dust or liquids, mainly water. The marking consists of the letters “IP” and two digits:
- the first digit refers to protection against solid particles (e.g. dust, dirt)
- the second digit informs about protection against solid liquid.
What is IP68 protection?
IP68 means full protection against dust (number 6) and the device can be “immersed in 1 meter of freshwater for more” (number 8).
What does IP68 mean?
One of the most popular protection classes for electronic devices is IP68. IP68 provides:
- full dust resistance
- protection against immersion of 1 meter or more
With this level of protection, the device can be used on the beach, in the rain, or during training, as the risk of damage to it in the event of accidental immersion is lower. It also means that the equipment will be more durable.
However, it should be remembered that IP68 does not protect against immersion for longer periods of time, may not cover salt or soapy water, and over time, the protection may become less effective.
Examples of products with the IP68 certificate
- sports cameras
- sports smartwatches
- smartphones from the higher price range (e.g. Samsung Galaxy, iPhone Pro)
- waterproof earphones.
What is IP69 protection?
IP69 offers the same level of protection against dust as IP68. The last number 9 means higher protection against liquids, including powerful high-temperature water jets.
What does IP69 (or IP69K) mean?
IP69 (also known as IP69K) is up to date the highest level of protection available in the IP system. IP69 provides:
- complete dust resistance
- protection against powerful high-temperature (up to 80°C) water jets (up to 100 bar).
Advantages of IP69
The advantage of devices with IP69 is that they are designed for use in extreme conditions (e.g. washing equipment with a water jet), so they are ideal for people in construction as well as for drivers or field technicians.
However, they are less aesthetically pleasing and heavier than devices with a lower level of protection and are more expensive. In addition, they are not as widely available in stores.
Examples of products with the IP69 certificate
- industrial equipment
- LED lamps for outdoor and military applications
- rugged phones
- reversing cameras for trucks.
IP68 vs IP69 comparison – which is better?
| Features | IP68 | IP69 |
|---|---|---|
| Dust protection | Full (6) | Full (6) |
| Water protection | Immersion depth >1 m | Powerful high-temperature water jets |
| Typical application | Consumer electronics | Industrial equipment used in extreme conditions |
| Durability | High | Very high |
| Device appearance | Slim and modern | Rugged and heavy |
| Device price | Medium to high | High to very high |
Where can I check the IP class of a device?
You will most often find information about the IP class in the technical specification of the product – for example, in the manual, on the manufacturer’s website, or in the online store description. Make sure that this is reliable information and not a marketing ploy.
What to choose, IP68 or IP69?
The IP68 and IP69 standards indicate that devices are characterized by significantly increased durability and functionality.
- If you are looking for equipment resistant to everyday water exposure and dust, choose IP68.
- If you need equipment for special tasks and use in special conditions, choose IP69.
Remember to always check the IP class before buying, especially if you want higher protection for your electronic device.
