Is IP67 or IP68 more waterproof?


In the world of technology, waterproof ratings have become essential when it comes to choosing electronic devices. Two common certifications are IP67 and IP68, both indicating varying degrees of water resistance. Understanding the differences between these ratings is crucial to determine which one suits your needs better. This article will explore the characteristics of each certification, their applications, and the level of protection they offer against water damage. By the end, you'll have a clear understanding of whether IP67 or IP68 is more waterproof.

IP67: The Basics

IP67 is an International Protection Marking that suggests the device can withstand complete immersion in water up to a depth of one meter for thirty minutes. The first digit "6" represents solid particle protection, meaning it's dustproof. The second digit "7" signifies liquid ingress protection. Therefore, IP67-rated devices can handle being submerged in water without suffering any damage. However, it's important to note that IP67 does not guarantee complete protection against all types of liquids, such as corrosive substances. Additionally, excessive water pressure or prolonged submersion beyond the specified time may still result in some water seepage.

IP68: Taking It Further

IP68 takes waterproofing to a higher level than IP67. Similar to IP67, the first digit "6" denotes solid particle protection. However, the second digit "8" indicates superior liquid ingress resistance. IP68-certified devices are capable of continuous immersion in water under conditions defined by the manufacturer. Although the exact specifications can vary, IP68 generally means the device can survive depths greater than one meter for a longer duration. This rating ensures maximum protection even when dealing with scenarios like accidental drop into a pool or prolonged exposure to rain and moisture. IP68 is indeed at the forefront of water resistance technology.


In summary, determining whether IP67 or IP68 is more waterproof depends on the specific requirements you have in mind. If your everyday activities involve occasional water exposure - like using your phone in a drizzle or accidentally dropping it into shallow water - IP67 should suffice. However, if you're engaged in activities that demand extended submersion or greater water depths, IP68 is the way to go. Ultimately, both ratings provide a level of protection against water damage, but with IP68, you can be confident in facing even more challenging wet environments without risking your device's functionality.
