When it comes to electronics and gadgets, water resistance is a crucial feature that can make or break a device. With the increasing demand for waterproof devices, manufacturers have introduced various ratings to signify the level of protection against water and moisture. Two of the most common ratings are IPX5 and IPX7, but what do they really mean? In this article, we’ll delve into the world of IP ratings and explore the differences between IPX5 and IPX7.
What are IP Ratings?
Before we dive into the specifics of IPX5 and IPX7, it’s essential to understand what IP ratings are. IP stands for Ingress Protection, which is a standardized rating system used to measure the level of protection against solid objects and water. The rating consists of two digits, with the first digit representing protection against solid objects and the second digit representing protection against water.
The First Digit: Solid Object Protection
The first digit of an IP rating ranges from 0 to 6, with 0 indicating no protection against solid objects and 6 indicating complete protection against dust. Here’s a breakdown of the solid object protection ratings:
- 0: No protection
- 1: Protection against objects larger than 50 mm (e.g., human hands)
- 2: Protection against objects larger than 12.5 mm (e.g., fingers)
- 3: Protection against objects larger than 2.5 mm (e.g., tools)
- 4: Protection against objects larger than 1 mm (e.g., wires)
- 5: Protection against dust (not completely sealed, but dust-resistant)
- 6: Completely sealed against dust
The Second Digit: Water Protection
The second digit of an IP rating ranges from 0 to 9, with 0 indicating no protection against water and 9 indicating protection against powerful high-temperature jets. Here’s a breakdown of the water protection ratings:
- 0: No protection
- 1: Protection against dripping water (vertically falling drops)
- 2: Protection against dripping water when tilted up to 15°
- 3: Protection against spraying water (up to 60° angle)
- 4: Protection against splashing water (all directions)
- 5: Protection against jetting water (12.5 L/min, 3.3 bar pressure)
- 6: Protection against powerful jetting water (100 L/min, 10 bar pressure)
- 7: Protection against immersion up to 1 meter for 30 minutes
- 8: Protection against immersion beyond 1 meter (manufacturer-specified depth)
- 9: Protection against powerful high-temperature jets (close-range, high-pressure spray)
IPX5: The Magic Number for Basic Water Resistance
Now that we’ve covered the basics of IP ratings, let’s dive into IPX5. The “X” in IPX5 indicates that the device has no specific rating for solid object protection, which means it may not be fully protected against dust or other foreign objects. However, the “5” in IPX5 indicates that the device is protected against jetting water.
What does IPX5 really mean?
A device with an IPX5 rating can withstand jetting water from a nozzle with a diameter of 6.3 mm, delivering 12.5 liters per minute at a pressure of 3.3 bar (approximately 50 psi). The test is conducted with the device tilted up to 90°, which simulates the force of water from a showerhead or a garden hose.
While IPX5 provides a good level of water resistance, it’s essential to note that it’s not suitable for devices that will be fully immersed in water. If you’re looking for a device that can withstand more severe water exposure, you may want to consider an IPX7 or higher rating.
IPX7: The Ultimate in Water Immersion Protection
IPX7 takes water resistance to the next level by providing protection against immersion in water beyond 1 meter. This rating is perfect for devices that will be used in harsh environments, such as outdoor activities, construction sites, or even underwater applications.
What does IPX7 really mean?
A device with an IPX7 rating can withstand immersion in water up to 1 meter for 30 minutes. The test involves submerging the device in a watertight chamber filled with water, and then observing its performance after 30 minutes. The device must continue to function normally, with no signs of water ingress or damage.
The key differences between IPX5 and IPX7
While both IPX5 and IPX7 provide excellent water resistance, there are significant differences between the two ratings:
| Ratings | Water Resistance | Test Conditions | Use Cases |
|---|---|---|---|
| IPX5 | Jetting water | 6.3 mm nozzle, 12.5 L/min, 3.3 bar, 90° tilt | Showerheads, garden hoses, light rain |
| IPX7 | Immersion up to 1 meter | 1 meter depth, 30 minutes, watertight chamber | Swimming, snorkeling, underwater photography, construction sites |
In summary, IPX5 is suitable for devices that will be exposed to water jets or light rain, while IPX7 is perfect for devices that will be fully immersed in water.
Real-World Applications of IPX5 and IPX7 Ratings
Now that we’ve explored the technical aspects of IPX5 and IPX7, let’s take a look at some real-world applications of these ratings:
IPX5 in Action
- Waterproof Bluetooth speakers designed for pool parties or outdoor gatherings
- Fitness trackers that can withstand sweat and rain
- Smartphones with IPX5 ratings for protection against accidental splashes
- Outdoor speakers and soundbars for gardens or patios
IPX7 in Action

- Diving watches and fitness trackers designed for swimmers and snorkelers
- Rugged smartphones for construction workers or outdoor enthusiasts
- Underwater headphones for swimmers and scuba divers
Conclusion
In conclusion, understanding the differences between IPX5 and IPX7 ratings is crucial when selecting devices that will be exposed to water or moisture. While IPX5 provides a good level of water resistance, IPX7 takes it to the next level with its ability to withstand immersion in water. By recognizing the strengths and limitations of each rating, you can make informed decisions when purchasing devices for various applications. Remember, when it comes to water resistance, it’s always better to err on the side of caution and choose a device with a higher IP rating to ensure your investment remains safe and functional.
What do IPX5 and IPX7 ratings mean?
The IPX5 and IPX7 ratings refer to the level of protection a device or product has against solid particles and water. The “IP” stands for Ingress Protection or International Protection Marking, and the “X” represents the level of protection against solid particles. The number that follows the “X” indicates the level of protection against water.
In the case of IPX5 and IPX7, the “5” and “7” refer to the degree of protection against water. IPX5 means the device can withstand water jets, while IPX7 means the device can be submerged in water beyond 1 meter deep. These ratings are essential in determining the durability and reliability of a product, especially in harsh environments or situations where it may be exposed to water or dust.
What is the difference between IPX5 and IPX7?
The main difference between IPX5 and IPX7 lies in the level of protection against water. IPX5 is resistant to water jets, which means it can withstand a powerful spray of water from any direction. On the other hand, IPX7 is resistant to immersion in water beyond 1 meter deep, making it more suitable for devices that may be fully submerged in water.
In practical terms, IPX5 is perfect for devices that may be exposed to rain, sweat, or accidental splashes, while IPX7 is ideal for devices that may be intentionally submerged in water, such as waterproof speakers or underwater cameras.
Are IPX5 and IPX7 the same as waterproof?
While IPX5 and IPX7 ratings offer a high level of protection against water, they are not exactly the same as being “waterproof.” Waterproof typically implies that a device can withstand any amount of water, regardless of the pressure or depth. IPX5 and IPX7 ratings, on the other hand, have specific definitions and testing protocols to ensure the device can withstand certain levels of water exposure.
For instance, a device with an IPX7 rating can be submerged in water beyond 1 meter deep, but it may not be able to withstand the pressure of deeper waters. Similarly, an IPX5-rated device can withstand water jets, but it may not be able to survive a full immersion. Therefore, it’s essential to understand the specific meaning and limitations of each rating.
Can I take my IPX5 or IPX7 device for a swim?
While IPX5 and IPX7 devices offer some level of protection against water, it’s essential to understand their limitations. An IPX5 device is not designed for swimming or immersion in water, and taking it for a swim may damage or destroy it. An IPX7 device, on the other hand, can withstand immersion in water beyond 1 meter deep, but it’s still important to follow the manufacturer’s guidelines and recommendations.
Before taking your device for a swim, make sure to check the manufacturer’s instructions and warranty terms. Some devices may have specific requirements or restrictions for use in water, and ignoring these guidelines may void the warranty or cause damage to the device.
How are IPX5 and IPX7 ratings tested?
The testing protocols for IPX5 and IPX7 ratings involve specific procedures to ensure the device meets the required standards. For IPX5, the device is subjected to a powerful spray of water from a nozzle, with the water pressure and flow rate carefully controlled. The device is then inspected for any signs of water ingress or damage.
For IPX7, the device is fully submerged in water beyond 1 meter deep for a specified period, usually 30 minutes. The device is then inspected for any signs of water ingress or damage. Both tests are designed to simulate real-world scenarios where the device may be exposed to water, and they provide a reliable way to determine the device’s level of protection.
Are IPX5 and IPX7 ratings only for electronic devices?
No, IPX5 and IPX7 ratings are not exclusive to electronic devices. Any product that requires protection against solid particles and water can be tested and certified for IPX5 and IPX7 ratings.
