IPX8 vs. IP68 Rating: Which is Better?

When rain, spills, and splashes threaten our devices, IPX8 and IP68 ratings come to the rescue. This article offers a concise exploration of what these ratings signify and presents a head-to-head comparison. Get ready to make informed decisions about the devices that can handle whatever life throws at them.

Basic of IPX8 and IP68

The IP rating system classifies the protection level provided by enclosures (e.g., electronic devices) against intrusion like dust, solid objects, water, and accidental contact. It's globally recognized and follows the IEC 60529 standard. Ratings consist of two digits for different protections:

• First Digit (Solid Protection): Ranges 0-6, showing defense against solid particles. A higher digit means better defense.

• Second Digit (Liquid Protection): Ranges 0-9, showing safeguarding against liquids. A higher digit means stronger liquid protection.

What's the meaning of IPX8?

IPX8 signifies a focus on water protection with no specific rating for solid particle defense. The "8" denotes the level of water protection. This rating signifies the device's ability to endure prolonged water immersion beyond IPX7 (temporary immersion), but specifics like depth and duration depend on the manufacturer's specifications.

What's the meaning of IP68?

The "6" in IP68 indicates the highest level of solid particle protection (dust-tight) according to the IP rating system. The "8" in IP68 indicates the highest level of water protection according to the IP rating system.

IP68 means that the device is protected against dust and can be submerged in water. The manufacturer will define the specific depth and duration of water immersion that the device can handle without damage.

IPX8 vs. IP68 Rating: Detailed Comparison

The key difference between IPX8 and IP68 is that IPX8 focuses on water resistance, while IP68 has a broader rating, indicating both dust and water resistance. Both ratings imply a high level of protection against water intrusion, but the IP68 rating adds an additional assurance of dust resistance. Let's see the details.

Water immersion capability

The "IPX8" rating specifically pertains to the water resistance. Devices with an IPX8 rating are designed to withstand continuous immersion in water beyond 1 meter (approximately 3.3 feet) for varying durations, which can range from 30 minutes to 4 hours or more, depending on the manufacturer.

The IP68 rating encompasses both water and dust resistance, indicating a higher level of protection. Like IPX8, the device is designed to be submerged under more than 1 meter (approximately 3.3 feet) of water.

Note: This assurance is applicable solely to non-corrosive liquids, which include substances like fresh water. It also doesn't guarantee indefinite underwater usage.

Dust resistance

The IPX8 rating focuses primarily on water resistance and doesn't provide specific information about dust protection. In this case, the absence of a digit following "IPX" means that dust resistance is not specified or tested as part of the rating.

However, the IP68 rating covers both water and dust resistance. The "6" in IP68 ensures that dust particles cannot penetrate the device's internal components, contributing to its overall durability and longevity.

Related products

IPX8 is often seen in products where water resistance is a major requirement, like underwater cameras, Bluetooth speakers and diving watches. These products are built to withstand water submersion without compromising their functionality.

IP68 is more commonly found in electronic devices that need to be both water-resistant and dust-tight. This rating is well-suited for smartphones, smartwatches, fitness trackers, E-readers and wireless earbuds.
