What is the difference between IP67 and IP68?

When it comes to electronic devices, especially those that are exposed to water or dust, you may have come across terms like IP67 and IP68. These are international standards that provide a rating system for the protection level of electronic devices against solids and liquids.

Understanding the IP Ratings

IP stands for Ingress Protection (or International Protection) and is followed by two numbers. The first number indicates the level of protection against solid objects, while the second number indicates the level of protection against liquids. The higher the number, the greater the protection.

What does IP67 mean?

An IP67-rated device offers a high level of protection against solids and liquids. Let's break down the numbers:

- The 6 in IP67 signifies that the device is dust-tight. It means no dust particles can enter the device, even in extreme conditions.

- The 7 in IP67 indicates that the device is protected against temporary immersion in water up to 1 meter depth for 30 minutes.

This rating is commonly found in smartphones, smartwatches, and other portable electronic devices meant to withstand occasional exposure to water and dust.

What about IP68?

An IP68-rated device provides an even higher level of protection compared to IP67:

- The 6 in IP68 still represents the same dust-tight enclosure as in IP67, ensuring no dust can penetrate the device.

- The 8 in IP68, however, indicates that the device is protected against continuous immersion in water beyond 1 meter depth. The specific depth and duration are specified by the manufacturer.

With an IP68 rating, devices are designed to withstand underwater activities like swimming or diving, and they are more resilient against accidental spills, splashes, and dust exposure.

Conclusion

The choice between IP67 and IP68 depends on the intended use of the electronic device. If you simply need protection against occasional exposure to water and dust, an IP67-rated device should suffice. However, if you plan to submerge or expose the device to water for extended periods, an IP68-rated device is a better option.

Remember, these ratings only certify the level of protection against solids and liquids. Other factors, such as durability, impact resistance, and general build quality, should also be considered when selecting an electronic device that can withstand harsh conditions.
