What is UL Rain Spray Testing?
UL Rain Spray Testing simulates rainfall to evaluate water resistance in electronics, lighting, enclosures, and electrical components. It prevents failures like short circuits, corrosion, and performance degradation—critical for products used outdoors or in humid environments.
Key Testing Standards
The BONAD BND-UL device complies with global standards:
- UL 60507: Water ingress protection for electrical equipment.
- ANSI Z21.10.3/Z21.58: Rain safety for gas appliances.
- CSA 4.3: Canadian electrical water protection.
- Additional certifications: UL 1598 (lighting), UL 1703 (solar), UL 1741 (inverters).
BONAD BND-UL Device: Design & Functionality
- Structure:
- Top section: 3 UL nozzles for vertical rain simulation.
- Bottom section: 1 nozzle for ground-level splash.
- Molded aluminum frame (lightweight, corrosion-resistant).
- Adjustability:
- Hand-operated height adjustment (stainless steel wheel).
- Universal brake casters for mobility.
- Precision Controls:
- “Red Flag” pressure gauges per nozzle.
- Imported UL-certified nozzles ensure accurate spray patterns.
