You’ve probably seen an IP rating on your gadgets, and you’ve probably wondered, What does this actually mean? Is it important? Will it affect your device’s ability to survive in different conditions? Let’s break it down and understand everything about what Ingress Protection (IP) ratings are all about, how they’re tested, and why they matter for your devices.
What is IP Testing?
IP testing is all about making sure that your device can endure the elements, whether that’s dust, dirt, or water. If you’re using it outdoors, in tough conditions like in a workshop, or in extreme weather conditions, you will be wondering if this device will be able to withstand these conditions. These IP ratings will give you the assurance that these devices will not get damaged after being exposed to dirt or water. IP ratings aren’t just numbers that are found on a product box , They’re obtained as a result of detailed and careful testing and engineering to make sure that your device will perform reliably in tough conditions like these.
Before getting into the specifics of IP testing and ratings, it’s essential to know that these ratings are standardized. This is to help you understand how well your device will be able to withstand when exposed to things like dust, dirt, moisture, or water. Without these ratings, it would be hard to figure out if your gadget can really handle the rough stuff.
Why Do IP Ratings Matter?
Without IP ratings, it would be difficult to assess whether a gadget could survive exposure to dirt or water. These ratings offer peace of mind, ensuring that your device will perform reliably in rugged conditions. Moreover, the standards behind IP ratings are universal, making it easy for you to compare devices and choose the right one for your needs.
Breaking Down the IP Rating
Let’s get into what an IP rating means. IP ratings are always two digits long, i.e, the first digit refers to how well the device is protected from solids (like dust), and the second digit refers to how well the device is protected against liquids (like water). Let’s break them down :
The First Digit: Protection Against Solids
0: No protection at all.
1: Protected against objects larger than 50mm, like hands or large tools.
2: Protected against objects larger than 12mm, like fingers.
3: Protected against objects larger than 2.5mm, like wires or small tools.
4: Protected against objects larger than 1mm, like screws and small wires.
5: Dust-protected – some dust might get in, but it won’t interfere with the operation and performance of the device.
6: Dust-tight – no dust can enter at all.
The Second Digit: Protection Against Liquids
0: No protection against liquids.
1: Protected against vertically falling water (light rain).
2: Protected against water falling at an angle (up to 15 degrees).
3: Protected against water sprayed from a 60-degree angle.
4: Protected against splashing water from any direction.
5: Protected against low-pressure water jets from any direction (like a garden hose).
6: Protected against powerful water jets.
7: Protected against immersion in water up to 1 meter for 30 minutes.
8: Protected against continuous immersion in water beyond 1 meter.
9: Protected against high-pressure water & high-temperature water jets.
So, a device with an IP67 rating, means that the device is dust proof and protected against immersion in water upto 1 meter. Understanding these ratings is vital as these ratings will tell you exactly what kind of environments the device can handle.

How Do Devices Achieve Their IP Rating?
You might be wondering, How do devices actually achieve their IP rating?A lot of engineering goes into making sure that the devices we use every day can withstand extreme conditions. There’s a lot of Design, material choices, and that goes into achieving that perfect IP rating. Here’s how it works:
1. Design & Engineering
Device manufacturers work hard to design their products inorder to keep out the dust and moisture by using sealed casings, rubber gaskets, and protective coatings to ensure that nothing gets in. For example, waterproof phones often have tightly sealed ports and a special coating on the circuit board to prevent damage and protect the internal circuits from water.
2. Materials
Some materials have better ressistance to water and dust comparitively . Metal, plastic, and glass are commonly used because they are able to form a tight seal and can withstand these elements. Materials like gaskets, seals, and adhesives are also used and it help to keep water and dust from getting inside by creating an impermeable barrier.
3. Testing
Once the design and materials are confirmed, then the manufactured device is subjected to rigorous Ingress Protection (IP) tests. This is where things like dust chambers and water tanks are used to make sure that the device meets the standards of its IP rating.
Types of IP Testing
1. Dust Ingress Testing (Solid Object Testing)
In Dust Ingress testing, the device is placed in a dust chamber and exposed to fine dust particles for a specific period. The goal is to see how well the device holds up to dust exposure over time. For IP5X and IP6X, devices are subjected to this type of testing to make sure that no dust will interfere with the device’s operation.
- IP5X: Some dust may enter, but it won’t impact functionality.
- IP6X: No dust can get inside the device.
2. Water Resistance Testing
Water resistance is tested by spraying or submerging the device in water. The device is subjected to water jets, sprays, or even full submersion, depending on its rating. This test is done to find out whether your device will be able to survive a splash, a downpour, or even being submerged in water. Testing standards vary depending on the rating. For example:
- IPX7: The device can handle being submerged in water for 30 minutes at a depth of 1 meter.
- IPX8: The device can withstand continuous submersion beyond 1 meter (often tested in deeper water).
3. Immersion Testing
Immersion testing involves fully submerging the device in water to ensure it can handle being underwater for a certain period. These kind of tests is commonly done for devices like smartphones, watches, or cameras that might accidentally be dropped in the pool or exposed to heavy rain.
4. Pressure & Temperature Tests
These tests check how well the device can handle extreme pressure or temperatures.
- Temperature testing can involve exposing the device to high or low temperatures to ensure it functions correctly. Some devices, especially industrial ones, may be tested for high-pressure environments or extreme heat and cold.
- Pressure tests are usually done for devices meant to withstand intense environments, such as industrial machinery or underwater equipment.
Real-World IP Testing Scenarios
Understanding these tests can have big impacts in the real world. For instance, a smartphone with an IP67 rating can be submerged in water for up to 30 minutes, but that same device might not be able to withstand the high-pressure jets from a fire hose. This is why it’s important to know the right IP ratin when you’re looking at devices for specific environments, like construction sites, the outdoors, or even the kitchen
Certification and Trust in IP Ratings
Once a device passes these tests, it earns its IP certification, which is a mark of trust. Devices are often tested by independent, certified labs like Elenergy to ensure accuracy. This certification ensures that the device meets the standards required for the stated IP rating, giving you confidence that your product will perform as promised.
Why IP Ratings Matter
IP ratings are more than just numbers on a box. They’re a guarantee that your device is built to withstand the conditions it’s meant to face. Whether you’re looking for protection from dust to keep particles from interfering with your device or water resistance to ensure it keeps working after a spill or splash, the right IP rating gives you peace of mind and helps you in making better decisions while choosing a device.
When Should You Care About IP Ratings?
- Outdoor Enthusiasts: Look for devices with high liquid resistance (IP68 or higher) for protection against water and rain.

Frequently Asked Questions (FAQ)
An IP rating (Ingress Protection rating) indicates how well a device is protected against dust, dirt, and moisture. The rating consists of two digits: the first number represents protection against solid objects (like dust), and the second number indicates protection against liquids (like water). For example, IP68 means the device is dustproof and can withstand submersion in water beyond 1 meter.
Both IP67 and IP68 offer high water resistance, but the key difference lies in the depth and duration of water exposure:
- IP67: Can withstand immersion in water up to 1 meter for 30 minutes.
- IP68: Can endure continuous immersion in water beyond 1 meter, often tested in deeper water.
Devices with an IP68 rating are typically better suited for extreme water conditions, such as being submerged for long periods or at greater depths.
Devices undergo rigorous testing to achieve their IP rating:
- Dust Ingress Testing: Devices are placed in a dust chamber and exposed to fine dust particles for a specific period. The goal is to ensure that no dust affects the device's functionality.
- Water Resistance Testing: Devices are subjected to water jets, sprays, or submersion to test their ability to handle moisture exposure.
- Immersion Testing: For devices rated IPX7 or higher, they are fully submerged in water to check their resistance.
- Temperature and Pressure Tests: Devices may also undergo extreme temperature and pressure testing to ensure they function in extreme environments.
The highest IP rating commonly available is IP69K. This rating indicates that a device is both dust-tight and can withstand high-pressure, high-temperature water jets, making it ideal for harsh industrial environments where equipment faces extreme conditions.
Once a device is manufactured, its IP rating cannot be changed unless additional modifications are made to improve its protective features. For example, adding seals or improving the casing could potentially increase the rating. However, manufacturers typically test their devices before sale to ensure the rating is accurate.
For devices used outdoors, such as smartphones, wearables, or outdoor gear, the ideal IP rating would be IP67 or IP68. These ratings ensure protection against both dust and water, providing resilience in environments where rain, moisture, and dirt are common. For extreme outdoor environments or industrial settings, you might consider devices rated IP69K for maximum protection.
