DO-160G Civil Aviation Electronics Anti-Drip Test Equipment For Avionics Class W Test
Product Information:
Standard: Conforms to RTCA DO-160F Environmental Conditions and Test Procedures for Airborne Equipment Section 26 Fire, Flammability.
Samples and restrictions: Avionics Class W.
Test purpose: To check whether W-type avionics equipment can ensure good performance of equipment and components in a dripping environment. The purpose is to verify the protective performance of the product shell when dripping.
Test principle: The dripping is ensured to meet the standard requirement of 140L/m2/h by controlling the water supply flow. The test equipment can generate uniform water flow on the entire surface of the sample shell.
Equipment structure and features: The dripping is ensured to meet the standard requirement of 140L/m2/h by controlling the water supply flow. The test equipment can generate uniform water flow on the entire surface of the sample shell.
Power supply: AC220V±5%/50Hz
Use environment: temperature 15-35°C, relative humidity 25%-75%, atmospheric pressure 86～106kpa (860mbar-1060mbar), flat ground, lighting, waterproof leakage switch (or socket), good water inlet and drainage functions
Water source: clean water or tap water without impurities, equipped with water cleaning and filtering device
Technical Parameters:
| Control and operation | PLC and touch screen intelligent control system |
| Inner and outer box dimensions | Inner box WDH=1000×1000mm×1000mm, outer box WDH=1280×2050mm×2150mm |
| Dripping test area | WD=800×800mm, other sizes can be customized |
| Dripping height | The distance between the needle and the sample is 0-500mm, by adjusting the turntable height or raising the sample |
| Dripping speed (water flow) | 140L/m²/h, automatic adjustment, refer to standard figure A, the equipment uses an electronic flow meter to control the amount of water injected into the water tank, so that the water output of the needle meets the standard requirements |
| Schematic drawing

|
| Rain drip tray pinhole diameter | 0.33mm±0.01mm |
| Drip hole spacing | 25mm×25mm, Matrix arrangement |
| Liquid temperature monitoring, ambient temperature monitoring, | The equipment is equipped with a thermostat, which can heat the sample. Ensure that the sample temperature is at least 10°C higher than the water temperature. The temperature parameters are limited according to JJF1101. Ensure the temperature uniformity in the experimental chamber. |
| Drip box location | Located on the top of the inner box, fixed position. |
| Test time | 0-99.9min, can be preset. |
| Box material | The inner box is made of SUS304 stainless steel. |
| Water circulation system | The water inlet has a cleaning filter device, and the test dripping water is automatically collected into the water tank through the chassis and can be recycled. |
| Safety protection | Phase sequence protection, leakage protection, water shortage protection, abnormal protection |
