In the world of electronic devices, water resistance has become a significant factor in determining the durability and reliability of the product. Two popular certifications that rate the water resistance of devices are IP67 and IP68. Both ratings indicate how effectively a device can withstand exposure to water, but there are some differences between them. In this article, we will explore the technical aspects of IP67 and IP68 and determine which one offers better water resistance.
Understanding IP Ratings
Before delving deeper into IP67 and IP68, let's first understand what an IP rating is. IP stands for Ingress Protection, and it is a standard set by the International Electrotechnical Commission (IEC) to classify the degree of protection against solids and liquids that may enter a device enclosure. The IP rating consists of two numbers, referring to different factors - the first digit denotes solid particle resistance, while the second digit indicates liquid ingress resistance.
IP67: Solid Protection and Immersion Resistance
IP67-rated devices offer a high level of protection against the intrusion of solid objects and complete immersion in water up to 1 meter depth for 30 minutes. The "6" in IP67 signifies dust-tight protection, ensuring no ingress of dust or harmful particles that could affect the device's performance. Meanwhile, the "7" indicates water resistance, allowing the device to be fully submerged without damage under specific conditions. However, it is important to note that IP67 does not guarantee the device's functionality when exposed to water at higher pressures, such as during water sports or swimming activities.
IP68: Dustproof and Continuous Submersion
IP68 takes the protection offered by IP67 a step further. With the highest level of protection against solids and liquids, an IP68-rated device is not only dust-tight but also capable of continuous immersion in water under certain conditions. The "8" in IP68 signifies the highest level of liquid ingress resistance, allowing the device to be submerged beyond 1 meter for a prolonged period without sustaining any damage. IP68 offers enhanced protection and is recommended for those who require rugged or waterproof devices for activities like underwater photography or diving.
In conclusion, if you are looking for a device with excellent water resistance, both IP67 and IP68 certifications offer reliable options. IP67 is ideal for everyday situations and accidental splashes, while IP68 provides a higher level of protection for more extreme conditions. Ultimately, your choice should depend on your specific needs and the level of water exposure you anticipate for your device.
