What is the difference between IP67 and IP68?

In today's world of electronic devices, we often come across terms like IP67 and IP68 when referring to their resistance against water and dust. But what do these ratings actually mean? And how do they differ from each other? In this article, we will dive into the details of these two commonly used IP (Ingress Protection) ratings and explore their differences.

IP67: Water and Dust Resistance

The IP67 rating is assigned to electronic devices that are designed to be resistant to both solids and liquids. The "IP" in IP67 stands for "Ingress Protection," while the number "6" represents the level of protection against solid objects. A device with an IP6x classification provides complete protection against dust and other small particles.

Moreover, the number "7" in IP67 signifies the device's ability to withstand immersion in up to 1 meter of water for a maximum of 30 minutes. This means that devices with an IP67 rating can handle accidental splashes, rain, and brief submersions without getting damaged. However, prolonged exposure to water beyond the specified depth or duration can still lead to water ingress and potential damage to the device.

IP68: Enhanced Water and Dust Resistance

The IP68 rating takes the concept of water and dust resistance a step further. Similar to IP67, the "IP" represents Ingress Protection, but the number "6" indicating protection against solids remains the same. However, the number "8" signifies enhanced water resistance compared to IP67.

A device with an IP68 rating can withstand continuous immersion in water greater than 1 meter for extended periods. The exact depth and time limits are determined by the manufacturer and may vary from one device to another. Therefore, it is important to check the specifications provided by the manufacturer for specific details on water resistance.

In addition to improved water resistance, IP68-rated devices also offer superior dust protection compared to their IP67 counterparts. However, it's worth noting that even though a device may be rated as IP68, it doesn't mean it is completely impervious to water or dust. Extreme conditions and usage outside the recommended guidelines can still result in damage.

The Decision: IP67 vs. IP68

When deciding between IP67 and IP68 ratings, it all depends on the intended use of the electronic device. If you anticipate frequent exposure to water, such as underwater photography or using the device in extreme weather conditions, an IP68 rating provides greater peace of mind.

However, if your device usage is primarily indoors or limited to occasional exposure to water and dust, an IP67 rating should suffice. It is crucial to assess your needs and choose a device with the appropriate Ingress Protection rating accordingly.

In conclusion, the primary difference between IP67 and IP68 lies in their level of water resistance. While both ratings guarantee protection against solids and liquids to some degree, IP68 offers enhanced performance in terms of water depth and duration. Ultimately, making an informed decision based on your specific requirements will ensure the longevity and reliability of your electronic devices.
