UL Rain Test Apparatus

Name: UL Rain Test Apparatus
Brand: Xi'an LIB Environmental Simulation Industry

LIB UL rain test apparatus simulates the natural rainfall environment to evaluate whether the electrical enclosure meets the rainproof performance requirements of the NEMA Type 3R grade in the UL 50E standard. The test sample was vertically sprayed with a water flow rate of 5.4 L/min/m², the nozzle angle was 45°, and it was continuously exposed to rain for about 1 hour to verify whether the equipment can effectively prevent rainwater from entering the electrical interior in an outdoor exposure environment. Typical applications include outdoor electricity meter boxes, street lighting control boxes, communication junction boxes and other scenarios.

Model: R-UL020

Standard: UL 50E

UL Rain Test Apparatus Features and Benefits

1. Precise control of the spray flow rate and nozzle Angle (45°) can truly reproduce the impact of natural rainfall on outdoor electrical equipment.

2. The nozzle layout is reasonable. Combined with adjustable brackets or turntable devices, it can cover shells of various sizes and structures.

3. Not only applicable to Type 3R, but also the parameters can be adjusted as needed for rain tests of other NEMA grades such as Type 3 and 3S.

4. Assist in certification and product quality control, and meet the requirements of UL 50E standards.

Details of UL Rain Test Apparatus


Precise nozzles	Water flow control system
Equipped with a stainless steel nozzle with a diameter of Φ5mm, it is installed on an adjustable height bracket to simulate the natural raindrop landing point.	The flow control valve and pressure gauge ensure the water flow is stable, and it is also equipped with a flowmeter for precise monitoring.
Adjustable test platform	Corrosion resistance test Apparatus
Height-adjustable sample shelf, with a load capacity of 100kg, supports rain test meters for test pieces with different-sized shells.	304 stainless steel, with a sturdy structure, can withstand long-term water flow impact and is suitable for high-frequency use in laboratories or certification institutions.
