Some products are marked as waterproof. Brands generally advertise them for use even in the rainy season. But how do they know if a product resists water and is reliable? That’s because they test their products in IPX7 waterproof test chambers. However, the majority don’t even know: What is the IPX7 waterproof test chamber?
Interestingly, these waterproof test chambers have become increasingly common across various industries. Manufacturers aim to make their products waterproof and get an edge over competitors. That’s why many products, even in electronics, are waterproof. In this article, I will discuss everything about IPX7 waterproof test chambers. Let’s get started.
What is the IPX 7 Waterproof Test Chamber?
First things first – IP is Ingress Protection Ratings. It tells us how good a product is when exposed to moisture or water splashes. IP in IPX7 indicates Ingress Protection. X indicates this rating does not include protection against dust. An IPX7 rating does not involve testing the product against. Lastly, the 7 indicates the water protection up to level 7.
Products with IPX7 have excellent water resistance. They can remain in good condition even if submerged in 1 meter of water. They can stay submerged for 30 minutes without any damage. However, products with IPX7 ratings are not tested for dust resistance. They may get defective if exposed to dust or debris.
The IPX7 waterproof test chamber is a testing device. It is used to test a product’s ability to withstand harsh splashes or submersion in water. These test chambers have a large water tank where the product is placed. Inside the water tank, there are sample holders. This holder holds the product under test to ensure a smooth testing experience.
The water tanks in these chambers have markings. During IPX7 testing, the product to be tested is placed at the 1-meter marking. When a product passes the IPX7 waterproof testing, it is marked as waterproof. This means it can be used in moist conditions or with splashes. Even if it is submerged in water, it will remain in good working conditions.
However, you should not use this product in dusty conditions. The purpose of this testing chamber is to improve the product’s reliability. Before this testing, many automotive electronic components were very sensitive to moisture. They used to malfunction if water splashed on them. However, product testing with IPX waterproof test chambers is reliable. Customers consider these parts trustworthy and buy them.
Components of an IPX7 Waterproof Test Chamber
IPX7 test chambers may seem like simple devices. However, they consist of components that enable their functionality. Each component of an IPX7 test chamber has a specific role. Below is the list of these components:
- Water Tank
- Sample Holder
- Depth Measurement
- Sealing and Gasket System
- Frame and Support Structure
- Water Inlet and Drainage System
As I said earlier, the water tank is the primary part where the test is conducted. It is filled with water and has depth measurement markings. For IPX7, ensure the product remains at the 1-meter marking for reliable testing. Sealing and gaskets are also important as they make the chamber leak-proof. This means the water level in the water tank remains constant during testing.
The product to be tested is not left in the water tank. Instead, it is carefully clamped on the sample holders. This ensures the product does not shake and remains stationary during testing. Water inlet and drainage systems are also very useful, as they help fill the water and then drain it after testing.
The outer frame or casing of these IPX7 test chambers is typically made of stainless steel. Even when exposed to moisture, the chambers do not rust for years. Some modern chambers also come with a glass side or a window. This glass window allows the operator to check the product’s condition in real time. However, you won’t see this side window on older test chambers.
How Does the IPX 7 Waterproof Test Chamber Work?
Interestingly, the working of the IPX7 waterproof test chamber is very simple. You can easily use this chamber for testing if you have some experience. In the section below, I will discuss the steps involved in this chamber’s operation.
1- Fill the Water Tank
First, you’ll have to fill the water tank. The water level in this water tank must be accurate. As I said earlier, IPX7 testing involves submerging the product to 1 meter of water for 30 minutes. So the water tank must have water to a 1-meter level. The measurement markings are present on the water tank.
You should fill the water precisely to the one-meter mark. Remember, the water level should not be lower or higher than this 1-meter mark. If you fill too much water, make sure to remove the excess. The aim is to fill the water till the 1-meter mark with precision. If the water is not at the 1-meter marking, it may affect the test results.
2- Positioning the Product
Once the tank is filled, place the product inside. It is worth noting that you cannot simply place products at random inside the tank. Instead, products to be tested must be carefully mounted on sample holders. These holders keep the product stable during the testing. Additionally, make sure the product is fully immersed in water. All of its sides and components are equally exposed to water.
This ensures that water reaches all small components for reliable testing. Right positioning is key when testing a product in an IPX7 waterproof chamber. You should mount the product in the sample holder similar to how it is supposed to be used in real-world conditions. Suppose it is used in an upright position in the real world. You should mount it in an upright position in the sample holders and vice versa.
3- Start the Timer
Once the product is correctly positioned in the chamber, you can start the timer. For IPX7 testing, the timer must be set for 30 minutes. Once the time is up, remove the product. During these 30 minutes, you should ensure that the product does not shake and that the chamber is not exposed to very high temperatures.
For this, the chamber must remain in a stable, stationary position. If the chamber moves, the product might shake, resulting in uneven immersion. This could affect the precision of IPX7 waterproof testing chambers. Testing parameters such as temperature, wind, and pressure should be within a moderate range. Remember, this testing should be done in a controlled environment.
4- Inspection & Evaluation
Once the timer reaches 30 minutes, you remove the product from the chambers. First, it is important to clean and dry the product completely. For this, use a dry microfiber cloth, depending on the type of product being tested. After drying, you will inspect and evaluate the products. If you notice any moisture signs inside the product, this means the product has failed the test.
Even frosting on the internal surfaces indicates a faulty product. On the other hand, if the product remains in good condition after the test, it is reliable. It is considered ready for use in real-world conditions by customers. Generally, manufacturers prepare to launch products with an IPX7 rating. In case of failure, they further improve the product so it passes the test again.
Advantages of IPX 7 Waterproof Test Chamber
Let’s discuss some key benefits of the IPX7 waterproof test chamber:
