When it comes to electronic devices, water and dust can be a deadly combo. That’s why manufacturers have developed various standards to ensure their products can withstand the elements. Two of the most popular standards are IP67 and IP69. But which one is better? In this article, we’ll delve into the world of ingress protection, exploring the differences between IP67 and IP69, and helping you make an informed decision for your next device.
What Is Ingress Protection?
Before we dive into the specifics of IP67 and IP69, it’s essential to understand what ingress protection is. Ingress protection, also known as IP rating, is a standard developed by the International Electrotechnical Commission (IEC) to measure the degree of protection provided by an enclosure or casing against solid objects and water.
The IP rating consists of two digits: the first digit represents protection against solid objects, and the second digit represents protection against water. The higher the rating, the better the protection.
What Is IP67?
IP67 is a popular rating that offers a high level of protection against dust and water. The breakdown of IP67 is as follows:
- 6: Complete protection against dust. No ingress of dust is possible, making it suitable for devices that need to operate in harsh environments.
- 7: Protection against immersion in water up to 1 meter (3.3 feet) for up to 30 minutes. This means the device can withstand being submerged in water for a short period.
Devices with an IP67 rating are suitable for use in wet conditions, such as near swimming pools, in kitchens, or in areas with high humidity. However, it’s essential to note that IP67 is not suitable for devices that need to be submerged in water for extended periods or at greater depths.
What Is IP69?
IP69 is a more recent development, offering an even higher level of protection against dust and water. The breakdown of IP69 is as follows:
- 6: Complete protection against dust, just like IP67.
- 9: Protection against powerful high-temperature jets of water. This rating is often referred to as “steam-jet cleaning” and is designed for devices that need to withstand harsh washing or cleaning conditions.
Devices with an IP69 rating are suitable for use in extreme environments, such as in industrial settings, outdoor equipment, or in areas with high-pressure washdowns. IP69 is a more stringent rating than IP67, making it ideal for devices that require the highest level of protection.
Key Differences Between IP67 And IP69
Now that we’ve explored the individual ratings, let’s highlight the key differences between IP67 and IP69:
Water Protection
The most significant difference is the level of water protection. IP67 offers protection against immersion up to 1 meter (3.3 feet) for up to 30 minutes, whereas IP69 protects against powerful high-temperature jets of water. IP69 is designed to withstand harsh washing or cleaning conditions, making it more suitable for devices that need to operate in heavy-duty environments.
Environmental Conditions
IP67 is suitable for devices that need to operate in wet conditions, such as near swimming pools or in kitchens. IP69, on the other hand, is designed for devices that need to withstand extreme environmental conditions, such as high-pressure washdowns, steam cleaning, or exposure to harsh chemicals.
Testing Methods
The testing methods for IP67 and IP69 differ significantly. IP67 testing involves submerging the device in water for a set period, whereas IP69 testing involves subjecting the device to powerful high-temperature jets of water. The IP69 test is more rigorous and simulates the harsh conditions found in industrial settings.
Which Is Better: IP67 Or IP69?
The answer depends on your specific needs and requirements. If you need a device that can withstand wet conditions, but not extreme environments, IP67 might be sufficient. However, if you require a device that can withstand harsh washing or cleaning conditions, high-pressure washdowns, or exposure to harsh chemicals, IP69 is the better choice.
When to Choose IP67:
- For devices that need to operate in wet conditions, such as near swimming pools or in kitchens.
- For devices that require a high level of dust protection, but don’t need to withstand extreme water protection.
When to Choose IP69:
- For devices that need to operate in extreme environments, such as in industrial settings or outdoor equipment.
- For devices that require the highest level of protection against water, dust, and harsh chemicals.
Real-World Applications
Both IP67 and IP69 have various real-world applications:
IP67 Applications
- Smartphones and tablets designed for outdoor use or in wet environments.
- Kitchen appliances, such as dishwashers and refrigerators, that need to withstand water and humidity.
- Industrial equipment, such as sensors and actuators, that require protection against dust and water.

- Outdoor equipment, such as traffic cameras and sensors, that require protection against water, dust, and harsh chemicals.
- Medical equipment, such as surgical instruments, that need to withstand steam sterilization and washing.
Conclusion
In the world of ingress protection, IP67 and IP69 are two of the most popular ratings. While both offer a high level of protection against dust and water, IP69 provides a more stringent level of protection against powerful high-temperature jets of water. When choosing between IP67 and IP69, consider the specific needs and requirements of your device or application. By understanding the differences between these two ratings, you can make an informed decision and ensure your device can withstand the elements.
In the end, the ultimate waterproof champion is IP69, offering the highest level of protection against dust, water, and harsh chemicals. However, IP67 is still a reliable choice for devices that don’t require the extreme level of protection offered by IP69.
What Is The Difference Between IP67 And IP69 Ratings?
The main difference between IP67 and IP69 ratings is the level of protection they offer against solid particles and water. IP67 is a rating that indicates protection against dust and immersion in water up to 1 meter for 30 minutes, whereas IP69 rating provides protection against dust and powerful high-temperature jets of water. In other words, IP69 is a more stringent rating that can withstand more extreme conditions.
In terms of real-world applications, IP67 is suitable for most outdoor uses, such as waterproof smartphones or watches. However, for more critical applications like industrial equipment, medical devices, or military gear, IP69 is the preferred rating. The extra protection afforded by IP69 ensures that these devices can function even in the most demanding environments.
Can IP67-rated Devices Be Used In Extreme Weather Conditions?
While IP67-rated devices can withstand some level of exposure to water and dust, they are not designed for extreme weather conditions. If you plan to use your device in very harsh environments, such as in areas with high-pressure water jets or extreme temperatures, an IP69 rating is more suitable. IP67 devices might not be able to withstand such conditions and may suffer from water ingress or other forms of damage.
That being said, IP67-rated devices can still be used in wet or dusty conditions, but with caution. For example, you can use an IP67-rated smartphone in the rain or near a pool, but you should avoid submerging it in water intentionally or exposing it to high-pressure water jets.
Are All Waterproof Devices IP67 Or IP69-rated?
Not all waterproof devices are IP67 or IP69-rated. While these ratings are widely recognized and respected, there are other methods of measuring water resistance. Some manufacturers may use their own proprietary ratings or testing methods, which might not be directly comparable to IP67 or IP69. In other cases, devices might be advertised as “waterproof” or “water-resistant” without specifying a particular rating.
When shopping for a waterproof device, it’s essential to look for the IP rating or other recognized standards to ensure that you’re getting a device that can withstand the level of water exposure you need. Don’t rely on vague advertising claims, and always check the specifications to get a clear understanding of the device’s water resistance capabilities.
Can IP69-rated Devices Be Used Underwater?
IP69-rated devices are designed to withstand powerful high-temperature jets of water, but that doesn’t necessarily mean they can be used underwater. While an IP69 rating provides an extremely high level of protection against water ingress, it’s still important to check the device’s specifications to see if it’s designed for underwater use.
Some IP69-rated devices might be intended for use in wet environments, such as on a boat or near a pool, but not necessarily for submersion in water. In contrast, devices designed for underwater use, such as scuba diving gear or underwater cameras, typically have specialized designs and materials to ensure their safety and functionality at depth.
Are IP67 And IP69 Ratings Only For Electronic Devices?
No, IP67 and IP69 ratings are not limited to electronic devices. These ratings can apply to any device or equipment that requires protection against solid particles and water. This includes mechanical devices, medical devices, automotive components, and even buildings or construction materials.
In fact, the IP rating system was originally developed for industrial applications, where equipment often needs to operate in harsh environments. Today, IP ratings are used across various industries, from consumer electronics to aerospace, to ensure that devices can function reliably and safely in a wide range of conditions.
Can IP67 Or IP69 Ratings Be Used Interchangeably?
No, IP67 and IP69 ratings should not be used interchangeably. While both ratings indicate a high level of protection against water and solid particles, they have distinct differences in terms of the level of protection they offer. IP67 is a more general-purpose rating suitable for most outdoor uses, whereas IP69 is a more stringent rating designed for extreme environments.
Using an IP67-rated device in an application that requires IP69-level protection can lead to failures or damage, as the device may not be designed to withstand the more extreme conditions specified by the IP69 rating. Similarly, using an IP69-rated device in a less demanding application may be overkill and unnecessary.
How Can I Test The Waterproofing Of A Device?
Testing the waterproofing of a device can be complex and requires specialized equipment. In most cases, it’s best to rely on the manufacturer’s claims and specifications, as they have already performed the necessary testing to ensure the device meets the specified IP rating.
However, if you’re unsure about a device’s water resistance or want to test it yourself, you can start by checking the device’s seals and gaskets for any signs of wear or damage. You can also perform simple tests, such as exposing the device to rain or splashing water, but be cautious not to push the device beyond its specified limits. For more rigorous testing, it’s recommended to contact the manufacturer or a certified testing laboratory.
