IPX8 Test: The importance of Immersion Test to Products

With the rapid development of science and technology, the use scenarios of various products are becoming increasingly diverse, and people's requirements for their waterproof performance are becoming more and more stringent. From daily electronic products to professional equipment in complex outdoor environments, waterproof ability has become a key indicator for measuring product quality and reliability. As an important standard in the field of waterproof testing, the IPX8 test is playing an irreplaceable role.

1. Definition of IPX8 Test

IPX8 is a waterproof rating in the international ingress protection standard. "IP" stands for the protection level, "X" means that the dustproof level is not required or tested, and "8" indicates that the product has excellent waterproof capabilities. Specifically, products that reach the IPX8 level must meet the requirements of being able to be continuously immersed in water more than 1 meter deep (common test depths range from 1.5 to 30 meters), under certain conditions for 30 minutes or more without affecting performance and without internal water leakage. For example, according to the IEC60529 standard, the bottom of the test housing with a height of less than 850mm should be 2 meters below the water surface for 60 minutes, after which it is checked whether water has entered the inside of the test housing and perform a functional check.

To perform a IPX8 test, a high pressure water tank is request.

2. IPX8 high pressure water tank

The IPX8 high-pressure water tank can accurately simulate the underwater environmental pressure at different depths. The water pressure test is more in line with the actual stress of the product in water. Due to the incompressibility of water, during the water pressure test, if the sealing performance of the product is poor, water will quickly and accurately penetrate into the product. This makes the test results clear at a glance and can accurately determine whether the product's waterproof performance meets the IPX8 grade standard.

The high pressure water tank made by Pego is made of SUS304 stainless steel, which has excellent corrosion resistance and wear resistance. The equipment configure with advanced pressure senor, can accurately control the pressure at the range of 0.1Mpa to 0.5Mpa, to simulate the water depth 1m to 50m. And user is very easy to set up the test pressure and test time.

To ensure the safety of the test process, Pego's design uses a dual pressure protection mechanism. On the one hand, the equipment is equipped with a safety pressure relief valve. When the pressure in the water tank exceeds the set maximum limit pressure, the safety valve will automatically open, to release excess pressure to prevent the pressure from continuing to rise and causing damage to the equipment and products. On the other hand, in terms of program control, an upper limit value for pressure tolerance is also set. Once the pressure exceeds the normal range, the system will automatically start the pressure relief program to ensure that the pressure is always in a safe and controllable state.

3. Application Scenario

● Consumer electronics: In the field of smartphones, many brands have passed the IPX8 test. Allowing mobile phones to be used normally in swimming, showering and other scenarios, and users do not need to worry about water damage. Smart watches are devices that are worn daily and often come into contact with water. After the IPX8 test, they can continue to provide health monitoring, information reminders and other functions when washing hands and swimming. Underwater cameras rely on the IPX8 test to ensure that they can withstand water pressure and prevent water from entering when shooting underwater, so as to record clear underwater images for users.

● For diving equipment such as diving computers, underwater lighting equipment, and breathing regulators, the IPX8 test is the key to ensuring the safety of divers and the normal operation of equipment. GPS devices and sports cameras used in outdoor adventures have been tested to work stably in severe weather conditions, such as heavy rain and stream immersion, providing important support for explorers such as navigation and recording.

● Outdoor distribution box: Outdoor distribution box is used to distribute and control electricity, and various electrical equipment and lines are installed inside. In harsh natural environments, such as rainstorms and floods, the distribution box needs to have good waterproof performance to protect the internal electrical equipment from water damage. The water pressure test of the distribution box through the IPX8 high-pressure water tank can verify whether its waterproof level meets the standard, ensuring that the distribution box can still work normally under extreme weather conditions and guaranteeing the stability of power supply.

With strict standards and scientific processes, the IPX8 test provides an accurate assessment of the waterproof performance of products in various industries. Through this test, products can operate stably in complex water environments, which not only improves product quality and reliability, but also greatly expands the product's usage scenarios, meets the increasingly diverse needs of consumers, and drives the continuous development of various industries.
