In our daily lives and industrial applications, products are often exposed to various water – containing environments.Among the various waterproof testing standards, IPX5 and IPX6 stand out for their ability to simulate more intense water exposure scenarios, which we will explore in detail.
1. Brief Introduction to IP code
The IP (Ingress Protection) standard is an international systemthat defines the degree of protection, provided by enclosures of electrical equipment against foreign objects (including dust) and water. The second digit in the IP code, denoted as IPX1 to IPX9, specifically addresses water resistance. The IPX scale ranges from 0 (no protection against water) to 9 (protection against high pressure/steam water jets under specific conditions). IPX5 and IPX6 are important levels within this system. They are designed to test a product’s ability to withstand water jets, which is a common form of water exposure in real – world situations such as heavy rain, car washes, or water – spraying industrial processes. These two levels play a key role in ensuring the reliability of products used in outdoor, industrial, and many other applications where water jet exposure is likely.
2. IPX5 Waterproof Test
2.1 Equipment Needed
To conduct the IPX5 test, a standard equipment are required. First and foremost, a water jet hose nozzle with an inner diameter of 6.3mm is essential. This specific nozzle is designed to create a water jet with the correct characteristics for the test. Additionally, a reliable flow meter is needed to accurately measure and maintain the water flow rate.
2.2 Detailed Procedure
The test begins by placing the sample on a stable platform. Position the nozzle 2.5 to 3 meters away from the sample. And arrange the sample in a way that allows the water jet to cover all possible working positions of the product. Set the water flow rate to 12.5±0.625 L/min. Then, the water jet is directed at the sample from all directions. Caculating test duration based on the surface area of the sample’s outer shell. For every square meter of the surface area (excluding the installation area), the test is conducted for at least 1 minute, with a minimum total test time of 3 minutes. After the test, the sample is carefully inspected for any signs of water ingress, such as water stains, water accumulation inside the product, or any malfunctions indicating water – related damage.
2.3 Industry Applications
IPX5 testing is widely used across outdoor electronic appliances, such as outdoor lighting (streetlight, garden lights and etc.), ruggedized smartphones and tables, and certain cart components (headlight, taillights) . The outdoor appliances are normally exposed to heavy rain or water splashes, performing IPX5 test can help the manufacturer to improve their design and quality of their products, and passing the IPX5 test gives users confidence that their device can keep working even in heavy rain environment.
3. IPX6 Waterproof Test
3.1 Equipment Requirements
The equipment for the IPX6 test shares some similarities with that of the IPX5 test, but there are also significant differences. Like the IPX5 test, it requires a water jet hose nozzle, but the inner diameter is 12.5mm. This larger – diameter nozzle is designed to produce a more powerful and intense water jet. A more robust flow – regulating device is also needed to ensure a stable water flow rate of (100±5) L/min.
3.2 Detailed Procedure
Firstly, place the sample on a secure and stable fixture. Position the nozzle 2.5 meters away from the sample. Then, direct the water jet at the sample from all possible directions. Carry out the test continuously for 3 minutes. During this period, the water jet should cover the entire surface of the sample evenly. After the 3 – minute test, the sample is carefully examined for any signs of water penetration, such as water droplets inside the product, water – induced malfunctions, or any visible water – related damage to the internal components.
3.3 Industry Applications
IPX6 testing is mainly applied to equipment that needs to operate in more extreme and harsh water – exposed environments, such as heavy-duty machines used in mining, construction, and ship – building industries, and high-end expedition-grade tents. Passing the IPX6 test ensures that their electrical components, control panels, and other sensitive parts can function properly even in such harsh conditions.
For IPX5 and IPX6 tests, Pego’s develops chamber-type equipment and open-type equipment to meet different testing demands. The IPX5 and IPX6 test chamber is suitable for small appliances, like headlight, taillight and electrical components. The IPX5 and IPX6 testing equipment is suitable for Large lamps and electrical cabinets. With excellent product quality and highly user-friendly design, our testing equipment stands out in the market and is especially favored by well-known laboratories such as TUV, SGS, and BV.
