When it comes to electronic devices, water resistance is a crucial feature that many consumers look for, especially for those who enjoy water activities or live in humid environments. The IP68 rating is often touted as a benchmark for water resistance, but is it really safe to swim with a device that has this rating? In this article, we’ll delve into the world of IP ratings, explore what IP68 means, and discuss its limitations when it comes to swimming.
What is IP68?
IP68 is a rating that indicates a device’s level of protection against solid particles and water. The “IP” stands for Ingress Protection, and the numbers that follow represent the device’s resistance to solid particles and water, respectively. In the case of IP68, the “6” means that the device is completely dust-tight, while the “8” indicates that it can withstand being submerged in water beyond 1 meter.
Breaking Down the IP Rating System
To understand the IP rating system, let’s break it down:
- The first digit (0-6) represents the device’s resistance to solid particles:
- 0: No protection
- 1: Protection against objects larger than 50 mm
- 2: Protection against objects larger than 12.5 mm
- 3: Protection against objects larger than 2.5 mm
- 4: Protection against objects larger than 1 mm
- 5: Dust-protected (not entirely dust-tight)
- 6: Dust-tight
- The second digit (0-9) represents the device’s resistance to water:
- 0: No protection
- 1: Protection against dripping water
- 2: Protection against dripping water when tilted up to 15°
- 3: Protection against spraying water
- 4: Protection against splashing water
- 5: Protection against low-pressure jets of water
- 6: Protection against high-pressure jets of water
- 7: Protection against immersion up to 1 meter
- 8: Protection against immersion beyond 1 meter
- 9: Protection against powerful high-temperature jets of water
What Does IP68 Mean for Swimming?
While IP68 is often associated with water resistance, it’s essential to understand that it’s not a guarantee that a device can withstand swimming. The rating only indicates that the device can survive being submerged in water beyond 1 meter, but it doesn’t account for other factors that come into play when swimming, such as:
- Water pressure: The pressure of the water increases with depth, which can cause damage to the device.
- Water temperature: Cold water can cause the device’s components to contract, potentially leading to damage.
- Water movement: The movement of the water can cause the device to be subjected to additional stress, potentially leading to damage.
- Chemicals in the water: Chlorine, salt, and other chemicals in the water can damage the device’s components.
Limitations of IP68 for Swimming
While IP68 is a robust rating, it’s not foolproof. Here are some limitations to consider:
- Depth limitations: IP68 devices are typically tested at a depth of 1-2 meters, but this doesn’t mean they can withstand deeper waters. The pressure at greater depths can cause damage to the device.
- Time limitations: IP68 devices are typically tested for a short period, usually 30 minutes. However, prolonged exposure to water can cause damage to the device.
- Water type limitations: IP68 devices are typically tested in fresh water, but saltwater or chlorinated water can be more corrosive and cause damage to the device.
Real-World Examples of IP68 Devices
Many devices on the market boast IP68 ratings, but what does this mean in real-world scenarios? Here are a few examples:
- Smartphones: Many high-end smartphones have IP68 ratings, but this doesn’t mean they can withstand swimming. For example, the Samsung Galaxy S21 has an IP68 rating, but Samsung recommends avoiding exposure to water beyond 1.5 meters for more than 30 minutes.
- Smartwatches: Some smartwatches, like the Apple Watch Series 7, have IP68 ratings, but Apple recommends avoiding exposure to water beyond 50 meters for more than 30 minutes.
- Action cameras: Action cameras like the GoPro Hero9 have IP68 ratings, but GoPro recommends avoiding exposure to water beyond 30 meters for more than 30 minutes.
Conclusion
While IP68 is a robust rating, it’s essential to understand its limitations when it comes to swimming. Devices with IP68 ratings can withstand being submerged in water beyond 1 meter, but they may not be suitable for swimming in deeper waters or for prolonged periods. It’s crucial to check the manufacturer’s recommendations and guidelines for using the device in water.
If you’re looking for a device that can withstand swimming, consider the following:
- Look for devices with higher IP ratings, such as IP69K, which offers better protection against powerful high-temperature jets of water.
- Check the manufacturer’s recommendations and guidelines for using the device in water.
- Consider using a waterproof case or accessory to provide additional protection.
- Avoid exposing your device to water beyond the recommended depth or time limits.
By understanding the limitations of IP68 and taking necessary precautions, you can enjoy your water activities while protecting your device.
What does IP68 mean in terms of water resistance?
IP68 is a rating given to devices that have passed specific tests for their ability to withstand solid particles (dust) and water. The “6” in IP68 indicates that the device is completely dust-tight, while the “8” signifies that it can withstand being submerged in water beyond 1 meter. However, the exact depth and duration of submersion are not standardized and can vary depending on the manufacturer’s specifications.
It’s essential to note that IP68 is not a universal standard, and different manufacturers may have different interpretations of what it means for their devices. Some devices with an IP68 rating might be able to withstand being submerged in shallow water for a short period, while others might be able to handle deeper and longer submersion. Always check the manufacturer’s specifications to understand the limits of your device’s water resistance.
Is IP68 OK for swimming?
While IP68-rated devices can withstand some exposure to water, it’s not always safe to assume they are suitable for swimming. The pressure and movement of water during swimming can be more intense than the conditions under which IP68 devices are tested. Additionally, the salt or chlorine content in pool water can potentially damage the device’s internal components.
If you plan to use your device while swimming, look for specific ratings or certifications that indicate it is designed for underwater use, such as IPX7 or higher. Even then, it’s crucial to follow the manufacturer’s guidelines and take necessary precautions to minimize the risk of damage. It’s also important to rinse your device with fresh water after exposure to salt or chlorinated water to prevent corrosion.
What is the difference between IP68 and IPX7?
IPX7 is a rating that specifically indicates a device can withstand being submerged in water up to 1 meter for 30 minutes. Unlike IP68, which includes protection against dust, IPX7 only focuses on water resistance. IPX7 is often considered a more reliable rating for devices intended for underwater use, as it provides a clearer indication of the device’s capabilities.
While IP68-rated devices might be able to handle some water exposure, IPX7-rated devices are generally more suitable for activities like swimming, snorkeling, or diving. However, it’s essential to remember that even with an IPX7 rating, devices are not invincible, and excessive pressure or prolonged submersion can still cause damage.
