IEC60529 IP5/6X Walk-In & Ground Embedded Sand And Dust Test Chamber
Complied Standards & Clauses
IEC60529:2013 "Degrees of protection provided by enclosure (IP code)" IP5X and IP6X
Equipment Overview
This equipment is suitable for testing electrical and electronic products, automobile and motorcycle parts, and seals in sand and dust environments to prevent sand and dust from entering the seals and shells. To test the performance of electronic and electrical products, automobile and motorcycle parts, and seals in use, storage, and transportation in sandy and dusty environments. The purpose of the test is to determine the possible harmful effects of particles carried by airflow on electrical products. The test can be used to simulate open sand and dust air environmental conditions induced by the natural environment or man-made disturbances such as vehicle movement.
Dust blowing method from top to bottom (vertical), the dust blowing time can be controlled by program.

| Sand and dust air circulation device | Circulation air ducts and high-power mixed-flow ventilators have an air extraction volume of 80 times the tested shell volume, and the air extraction speed does not exceed 60 times the shell volume per hour. And the speed of the air flow can make the dust evenly distributed in the test chamber. The airflow in the test chamber is mainly top-down vertical airflow rather than laminar flow. The pressure gauge has a calibration interface. |

| Dust drying system | The equipment is equipped with a dust drying heating device, and there is a heating button on the controller control screen. When the dust is found to be a little moist during the test, you can turn on the heating button in the control screen and start the dust heating device to dry the dust. The button can be turned off after the dust has dried. The drying process will not affect the test process, effectively ensuring the dust concentration in the test chamber and ensuring the accuracy of the test data. |
| How to change dust | Use a manual vacuum cleaner to replace the dust manually, and the dust can be easily replaced at any time |
1. The equipment is a walk-in structure with spliced warehouse boards. There is a funnel in each of the four corners. The middle flat adopts a dust brush structure. The side-through dust brush structure brushes dust into the funnels on both sides.
