The Science Behind IPX9K Testing: Understanding High Temperature Pressure Jet Waterproof Test Chamber

The IPX9K High Temperature Pressure Jet Waterproof Test Chamber is used to test the IPX9K waterproof level of the product, and its waterproof performance is considered to be relatively high among the waterproof level detection instruments.

The IPX9 High Temperature Pressure Jet Waterproof Test Chamber mainly sprays the sample shell with high-temperature and high-pressure steam water.
Under such high temperature and pressure conditions, there is a very severe test on the sealing material of the shell. Generally, this type of testing is mostly applied in the field of automotive accessories, such as engines, automotive power supplies, headlights, automotive wiring harnesses, automotive exhaust fans, etc.

The damage of natural water (such as rainwater, seawater, river water, etc.) to products and materials causes incalculable economic losses every year. The damage caused mainly includes corrosion, fading, deformation, strength reduction, expansion, mold, etc., especially electrical products that are prone to fire due to short circuits caused by rainwater. Therefore, it is a key procedure to conduct shell protection water testing for specific products or materials.

According to the new standard GB4208-2017 (replacing GB4208-2008), IPX9 waterproofing testing requires heating the water temperature to around 80 ℃. The requirements for testing vary depending on the size of the casing.

For small samples, the IPX9 waterproof test time is 30 seconds per location. The required speed is 5 ± 1r/min. For large samples, the testing distance (nozzle to sample surface) is 175 ± 25mm. If the distance is too far, the pressure of spraying water onto the sample is not enough. If the distance is too close, the area of spraying water is not enough to fully spray water.

Characteristics of IPX9K High Temperature Pressure Jet Waterproof Test Chamber：
1. The ipx9K High Temperature Pressure Jet Waterproof Test Chamber is suitable for testing the IPX9K waterproof level of products.
2. The shell is processed from steel plate, and the surface is sprayed with silver gray baking paint, which is beautiful and durable.

3. All turntables are made of SUS304 # stainless steel plates, ensuring that they do not rust during long-term use.
4. Open structure; It also comes with a water tank and cannot be reused; Automatically control water inflow.
5. Four fan-shaped nozzles are evenly distributed within a vertical 90 ° range in the middle of the chamber, designed and manufactured strictly according to standards.
6. Turntable drive: Using a stepper motor, the speed can be set (adjustable) on the touch screen, and can be adjusted within the standard range.
7. The IPx9K High Temperature Pressure Jet Waterproof Test Chamber adopts the original Italian imported water pump, which is resistant to high temperature and pressure, can be used for a long time, and has stable performance.
8. The testing time can be set on the touch screen, with a setting range of 0-999min (adjustable).

Several key points for testing the IPX9 High Temperature Pressure Jet Waterproof Test Chamber:
1. The tested nozzles have four angles, arranged in the 0 °, 30 °, 60 °, and 90 ° directions;
2. The positions of the two nozzles in the 0 ° and 90 ° directions can be adjusted, and the adjustment distance can be adjusted according to the size of the sample. However, it is necessary to ensure that after adjustment, steam can be sprayed onto the surface of the sample;
3. The distance between the nozzle and the sample is adjustable, with a radius range of 125 ± 25mm;
4. The IPX9K High Temperature Pressure Jet Waterproof Test Chamber adopts a fan-shaped nozzle, and the water spray is also fan-shaped, which can ensure high-pressure water spraying within the range.

JL-9K1L High Temperature & Pressure Jet Waterproof Test Chamber is according to IEC60529:1989 +A1:1999 +A2：2013 《Degrees of protection provided by enclosures(IP Code)》, GB4208, DIN40050-9，GB7000.1，ISO20653 and for protection level IPX9K testing. It is a waterproof test machine designed for vehicle spare parts, electrical and electronic industry, to simulate natural environment or human factors.
