What is the difference between 1p67 and 1p68

When it comes to understanding the nuances of technical specifications, it can often be challenging to keep up with the latest advancements. One area that frequently causes confusion is the difference between products labeled as 1p67 and 1p68. In this article, we will delve into the details and explore the distinctions between these two specifications.

Understanding IP67

The first specification we will examine is IP67. The term "IP" stands for Ingress Protection, which is a standard set by the International Electrotechnical Commission (IEC). The initial digit, represented by "6," refers to the level of protection against solid particles, such as dust. In the case of IP67, this means that the product is completely dust-tight.

The second digit, denoted by "7," addresses the resistance to liquid ingress. An IP67-rated product provides protection against immersion in water up to a depth of one meter for up to 30 minutes. This makes it suitable for applications where exposure to water or dust is likely, such as outdoor electronics or industrial machinery.

Exploring IP68

IP68 takes the protection provided by IP67 to the next level. Like IP67, the first digit represents solid particle protection, which remains the same at the highest rating of "6." Therefore, IP68 devices are also completely dust-tight.

However, the second digit, represented by "8," indicates an enhanced liquid ingress protection level compared to IP67. An IP68-rated product can withstand continuous immersion in water under specified conditions. While IP67 allows temporary immersion, IP68 ensures the device's durability even in submerged environments, making it suitable for underwater equipment or devices that may encounter prolonged exposure to water.


In summary, the key difference between IP67 and IP68 lies in their respective liquid ingress protection capabilities. While both specifications offer excellent dust-tight protection, IP68 provides a higher level of resistance against water immersion. Whether selecting a device for outdoor use or underwater applications, understanding these distinctions is crucial to ensure product durability and reliability.

It's important to note that manufacturers must conduct tests and adhere to specific guidelines to obtain an official IP rating certification for their products. Consumers and users should refer to the product's documentation or contact the manufacturer directly for any further information regarding IP ratings and their applicability to specific scenarios.
