IEC60529 IP5/6X EV Charge Station Walk-In Sand & 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 electronic and electrical
products, automobile and motorcycle accessories, and seals in sandy
and dusty environments to prevent sand and dust from entering the
seals and casings. 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 testing is to determine the possible harmful
effects that airflow-borne particles may have on electrical
products. The test can be used to simulate open-air sand and dust
air environmental conditions caused by natural environments or
man-made disturbances such as vehicle movement. Technical Parameters

picture for details (including 500mm aisle size) | | Test sample specifications | Charging stations, electrical cabinets, energy storage cabinets The size range is not larger than: W (260~2000) × D (200~1000) × H
(1000~3000) mm | | Function parameters | | Working room temperature | RT+10℃～+70℃ | | Working humidity | ≤75%R.H | | Product vacuum degree | ≤60KPa | | Dust composition | Talcum powder | | Composition of dust particles | Dry talcum powder that can pass through a square hole sieve with a
mesh size of 75µm and a wire mesh diameter of 50µm | | Dust concentration | 2～4kg/m3 | | Air flow meter | Mechanical type | | Airflow speed | Not more than 2m/s | | Time of control | Dust blowing control cycle: 1s ~ 99h (adjustable), test time
timing: 1s ~ 99h (adjustable), vibration time: 1S ~ 99H
(adjustable) | | Metal mesh | Nominal line length: ≥50μm, standard spacing between lines: ≥75μm. | | 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. | | Load-bearing capacity of cargo platform | Not less than 500kg | | 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. 2. There is a rotating sand and dust feeding device at the air
inlet end of the working room to meet the needs of dust blowing. 3. The circulating air duct is equipped with a heating and
dehumidification device. 4. There is an observation window on the door. The test box has
double doors and is sealed with double layers of aging-resistant
silicone rubber. 5. The outer wall material of the test room and whirlpool duct is
made of high-strength double-sided galvanized steel plate with fine
powder baking paint on the surface. The inner wall is processed and
formed by SUS304 stainless steel plate. The frame is made of 10#
square tube after anti-rust treatment and spraying. 6. Temperature and humidity control uses an intelligent controller
(relative humidity uses a direct-reading sensor) (panel control
uses a touch screen). Dust blowing method from top to bottom (vertical), the dust blowing
time can be controlled by program. Cabinet Configuration

resistant sealing silicone strips on the door. Details Introduction
| Dust test device | a) A funnel (4 pieces in total) is installed at each of the four
corners of the studio, 2 funnels in the middle (6 funnels in
total), and a metal dust filter is installed on the upper surface
of the funnel. b) A set of rotating devices is designed between the lower part of
the loading platform and the bottom plate of the warehouse, and the
dust is swept into the funnels at the four corners through dust
brushes. c) A high-power mixed-flow fan is installed at the bottom of the
funnel to send the dust to the working room through the circulating
air duct for settlement. d) Meet the dust blowing test requirements of IP5X and IP6X. The
dust blowing airflow in the test room can make the dust evenly
suspended and distributed in the test chamber. The blowing dust
concentration is 2~4kg/m3 (adjustable). The test dust settles
evenly and slowly on the substrate. On the test sample, it does not
exceed 2m/s (adjustable). | | Test hole | a) The equipment is equipped with φ50 mm test holes (one on the
