Is IP67 or IP68 more waterproof?

The Ingress Protection (IP) rating system is used to classify and rate the degree of protection provided by electrical enclosures against intrusion, dust, and water. Among the various IP ratings, IP67 and IP68 are the ones most commonly associated with waterproofness. In this article, we will delve into the technical details of these two ratings and determine which one offers better water resistance.

Understanding IP67

IP67 is a standard that defines the level of protection offered by an enclosure against liquid ingress. The "6" in IP67 represents the highest level of protection against solid objects such as dust and particulates. Meanwhile, the "7" indicates a high level of protection against water immersion up to 1 meter for a duration of 30 minutes. This means that a device with an IP67 rating should be able to withstand accidental submersion in water without damage.

Deconstructing IP68

IP68 takes the waterproof capabilities a step further. Similar to IP67, the "6" in IP68 denotes the highest level of protection against solids. However, the "8" signifies a higher level of water resistance compared to IP67. A device with an IP68 rating should be able to endure complete submersion in water beyond 1 meter for a specified amount of time. The exact depth and duration can vary depending on manufacturers’ specifications.

Which one is more waterproof?

Comparing IP67 and IP68, it is clear that IP68 offers superior water resistance. While IP67 guarantees protection against temporary immersion, IP68 provides a higher level of security against prolonged submersion at greater depths. Therefore, if you require a device that can withstand more extreme water conditions, such as underwater photography or diving, IP68-rated devices would be the more suitable choice.

It is important to note that IP ratings only measure dust and water resistance, not durability against other factors like impact or temperature variations. Additionally, the effectiveness of the rating may vary depending on the design and build quality of the device. Therefore, it is always advisable to check the product specifications and reviews before purchasing any waterproof device to ensure it meets your specific requirements.

In conclusion, while both IP67 and IP68 provide a certain level of protection against water ingress, IP68 offers better waterproofness due to its ability to withstand deeper and longer periods of submersion. However, the final choice should depend on the intended use and environmental conditions in which the device will be operated.
