LIB's Waterproof UL 50E Spray Rain Test Apparatus is constructed using high-quality SUS 304 stainless steel and formed aluminum materials, offering excellent corrosion resistance and long-term durability in wet testing environments. The spray device height is freely adjustable within a wide range, allowing the intersection point of water columns to be set between approximately 1000 mm and 2000 mm from the ground. This flexibility ensures accurate testing of enclosures with different sizes and installation heights.
Key Advantages
1. Full Compliance with UL 50E Rain Spray Requirements: the apparatus is designed strictly in accordance with UL 50E specifications, including nozzle spacing, spray angle, hole diameter, and water pressure. The 45° spray angle and standardized flow conditions ensure that enclosure performance is evaluated under realistic rain exposure scenarios, providing reliable compliance data for certification and inspection.
2. Adjustable Spray Height for Flexible Testing: with a spray device height adjustment range of approximately 1000–2000 mm, the system can accommodate enclosures of different sizes and mounting positions. This adjustability makes it suitable for testing everything from small electrical boxes to large distribution cabinets without structural modification.
3. Stable and Accurate Water Control: an electromagnetic flowmeter combined with precise pressure regulation allows accurate control of water flow and pressure. Typical operating water pressure is maintained around 34.5 kPa, ensuring consistent spray intensity and repeatable test results across multiple test cycles.
4. Durable Industrial-Grade Construction: the internal and external structures are made from SUS 304 stainless steel, providing excellent resistance to corrosion, rust, and mechanical wear. The formed aluminum frame ensures structural stability while remaining easy to clean and maintain after repeated water exposure.
5. User-Friendly Operation and Mobility: the apparatus features a simple mechanical adjustment system and does not require complex electrical operation for basic testing. A reinforced base with universal brake casters allows easy movement and secure positioning within laboratories or testing areas.
6. Automatic Water Supply and Purification System: an integrated automatic water supply system with filtration maintains clean, constant-flow water during testing. This reduces nozzle blockage, improves spray uniformity, and minimizes maintenance requirements over long-term use.

Typical Tests Performed
This UL rain spray test apparatus is commonly used to perform simulated rainfall and angled spray tests on electrical enclosures intended for outdoor installation. During testing, clean water is supplied at a controlled flow rate of approximately 10 L/min (±5%), with pressure typically maintained within a range suitable for UL 50E evaluation. The enclosure is exposed to continuous rain spray from multiple directions for a specified duration, allowing engineers to observe water ingress, leakage paths, and sealing performance. Typical applications include rain resistance testing of outdoor luminaires, street lighting housings, electrical cabinets, junction boxes, and communication enclosures under standardized conditions that reflect real-world environmental exposure.

FAQs
Q1: Can the Waterproof UL 50E Spray Rain Test Apparatus be customized for larger enclosures?
Yes. The sample platform size, overall dimensions, and spray structure can be customized to accommodate larger or non-standard enclosures while still maintaining compliance with UL 50E test principles.
Q2: Does the apparatus require a complex power supply to operate?
No. The rain spray testing function itself does not require an external power supply. The system relies on controlled water pressure and flow, making installation and operation simple and cost-effective.
Q3: How long is the delivery time for customized configurations?
Standard models are typically delivered within 7–15 days. For customized sizes or special configurations, production time may be slightly extended, but LIB closely manages schedules to ensure timely delivery and fast project implementation.
