IEC 60068-2-68 Floor Stand Large Sand and Dust Test Chamber
Complied Standards & Clauses
IEC 60068-2-68: 2001 Environmental testing- Part 2: Tests- Test L Dust and sand.
Product 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.
Technical Parameters
1. Volume and dimensions | |
1.1 Effective volume of inner chamber | About 19.8 cubic meters |
1.2 Inner chamber dimensions | 3000*2000*3300mm (W*D*H) |
1.3 Outer chamber dimensions | About 3200*27000*4500 mm(W*D*H) |
Test sample specifications | Charging stations, electrical cabinets, energy storage cabinets |
2. Function parameters | |
2.1 Working room temperature | RT+10℃~+70℃ |
2.2 Working humidity | ≤75%R.H |
2.3 Product vacuum degree | ≤60KPa |
2.4 Dust composition | Talcum powder |
2.5 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 |
2.6 Dust concentration | 2~4kg/m3 |
2.7 Air flow meter | Mechanical type |
2.8 Airflow speed | Not more than 2m/s |
2.9 Time of control | Dust blowing control cycle: 1s ~ 99h (adjustable), test time timing: 1s ~ 99h (adjustable), vibration time: 1S ~ 99H (adjustable) |
2.10 Metal mesh | Nominal line length: ≥50μm, standard spacing between lines: ≥75μm. |
2.11 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 airflow 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. |
2.12 Load-bearing capacity of cargo platform | Not less than 1000kg |
2.13 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 on 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. |
2.14 How to change dust | Use a manual vacuum cleaner to replace the dust, and the dust can be easily replaced at any time |
