When it comes to electronic devices, especially those designed for outdoor use or in harsh environments, durability and resistance to elements like water and dust are crucial. One term that has become synonymous with device protection is IP68. But what does IP68 mean, and how does it impact the usability and longevity of your devices? In this comprehensive guide, we will delve into the world of Ingress Protection (IP) ratings, focusing on IP68, to understand its significance, testing procedures, and implications for device manufacturers and users alike.
Introduction to Ingress Protection Ratings
Ingress Protection (IP) ratings are standards that measure the degree of protection a device has against solid particles (like dust) and water. These ratings are defined by the International Electrotechnical Commission (IEC) in publication 60529 and are crucial for determining the suitability of a device for use in various environments. The IP rating is typically represented by the letters “IP” followed by two digits, each providing specific information about the level of protection against solids and liquids, respectively.
Breaking Down the IP Rating
To understand IP68, it’s essential to break down what each part of the rating signifies. The first digit after “IP” refers to the level of protection against solid particles, and the second digit refers to the level of protection against liquids.
- The first digit can range from 0 to 6, with 0 indicating no protection and 6 indicating dust-tight conditions where no dust can enter.
- The second digit can range from 0 to 9, with 0 indicating no protection and 9 indicating protection against powerful high-temperature jets of water.
Understanding the First Digit: Solid Particle Protection
The levels of protection against solid particles are defined as follows:
– 0: No protection
– 1: Protected against solid objects greater than 50mm
– 2: Protected against solid objects greater than 12.5mm
– 3: Protected against solid objects greater than 2.5mm
– 4: Protected against solid objects greater than 1mm
– 5: Dust protected; ingress of dust is not entirely prevented but does not interfere with the operation of the device
– 6: Dust-tight; no ingress of dust
Understanding the Second Digit: Liquid Protection
The levels of protection against liquids are defined as follows:
– 0: No protection
– 1: Protected against dripping water
– 2: Protected against dripping water when tilted up to 15 degrees
– 3: Protected against spraying water
– 4: Protected against splashing water
– 5: Protected against jetting water
– 6: Protected against powerful jets of water
– 7: Protected against immersion up to 1m for 30 minutes
– 8: Protected against immersion beyond 1m (specified by the manufacturer)
– 9: Protected against powerful high-temperature jets of water
What Does IP68 Mean?
Given the breakdown of IP ratings, IP68 signifies that a device is dust-tight (6) and can withstand being submerged in water beyond 1 meter (8), with the exact depth specified by the manufacturer. This rating is one of the highest levels of protection against both dust and water, making devices with an IP68 rating highly durable and suitable for use in harsh environments.
Testing for IP68
Testing for IP68 involves two main procedures: one for dust protection and another for water protection. For dust, the device is placed in a dust chamber where dust is blown around it for a specified period, usually 8 hours, to ensure that no dust enters the device. For water, the device is submerged in water at a depth specified by the manufacturer (since the standard only requires it to be beyond 1 meter) for 30 minutes. The device must continue to function normally after both tests.
Implications of IP68 for Device Manufacturers and Users
For device manufacturers, achieving an IP68 rating can be a significant selling point, especially for devices intended for outdoor use, such as smartphones, smartwatches, and rugged tablets. It requires careful design and engineering to ensure that all openings and seals are secure against both dust and water.
For users, an IP68 rating provides peace of mind when using devices in environments where they might be exposed to water or dust. It means that accidental drops into water or use in dusty conditions will not damage the device. However, it’s crucial to note that while IP68 devices are highly resistant, they are not invincible. The rating does not cover damage from external forces (like being crushed) or from water pressure at extreme depths.
Conclusion
In conclusion, the IP68 rating is a significant indicator of a device’s durability and resistance to environmental factors. Understanding what IP68 means can help both manufacturers and users make informed decisions about device suitability for various applications. Whether you’re looking for a smartphone that can withstand accidental dips in water or a piece of equipment for industrial use that needs to be dust-tight, knowing the IP rating can be a crucial factor in your choice. As technology advances and devices become more integral to our daily lives, the importance of Ingress Protection ratings like IP68 will only continue to grow.
Given the vast array of devices now available with IP68 ratings, from consumer electronics to industrial equipment, the future of durable and resistant technology looks promising.

What is the meaning of IP68 and how does it relate to ingress protection ratings?
The IP68 rating is a measure of a device’s ability to withstand the ingress of solid particles and water. The “IP” stands for Ingress Protection, which is a standard used to define the levels of sealing effectiveness of electrical enclosures against intrusion from foreign bodies and moisture. The “6” in IP68 refers to the device’s ability to withstand the ingress of dust and other solid particles, with a rating of 6 indicating that the device is completely dust-tight. This means that the device is designed to prevent the entry of dust and other solid particles, which can cause damage to the internal components.
The “8” in IP68 refers to the device’s ability to withstand being submerged in water. A rating of 8 indicates that the device can withstand being submerged in water beyond 1 meter, with the exact conditions specified by the manufacturer. For example, a device with an IP68 rating may be able to withstand being submerged in water up to 2 meters for a period of 30 minutes. This makes IP68-rated devices suitable for use in harsh environments where they may be exposed to water or dust, such as in outdoor or industrial settings. By understanding the meaning of IP68, consumers can make informed decisions when selecting devices that need to withstand challenging environmental conditions.
How are ingress protection ratings determined and what tests are involved?
Ingress protection ratings are determined through a series of tests that evaluate a device’s ability to withstand the ingress of solid particles and water. The tests are defined by the International Electrotechnical Commission (IEC) and involve subjecting the device to various conditions, such as dust and water immersion. For example, to test a device’s dust resistance, it may be placed in a chamber filled with dust and then operated to see if the dust enters the device. Similarly, to test a device’s water resistance, it may be submerged in water and then operated to see if water enters the device.
The tests involved in determining ingress protection ratings are rigorous and designed to simulate real-world conditions. For example, a device may be subjected to a series of water jets or immersed in water at different depths and for different periods. The device is then inspected for any signs of water ingress or damage. The results of these tests are used to determine the device’s ingress protection rating, which is then indicated by the IP code. By undergoing these tests, manufacturers can ensure that their devices meet the required standards for ingress protection, and consumers can have confidence in the device’s ability to withstand harsh environmental conditions.
What are the different levels of ingress protection ratings and how do they compare?
The different levels of ingress protection ratings are defined by the IP code, which consists of two digits. The first digit refers to the device’s ability to withstand the ingress of solid particles, with ratings ranging from 0 (no protection) to 6 (dust-tight). The second digit refers to the device’s ability to withstand the ingress of water, with ratings ranging from 0 (no protection) to 9 (high-pressure water jets). For example, a device with an IP67 rating is dust-tight and can withstand being submerged in water up to 1 meter for 30 minutes.
The different levels of ingress protection ratings are designed to provide a clear indication of a device’s ability to withstand various environmental conditions. By comparing the different levels of ingress protection ratings, consumers can select devices that meet their specific needs.
