Complied Standards & Clauses

Conforms to RTCA DO-160F Environmental Conditions and Test Procedures for Airborne Equipment Section 26 Fire, Flammability.

Product Overview

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.

Technical Parameters

Power supply: AC220V±5%, 50/60Hz

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

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
