UL Water Spray Test Device

The UL Water Spray Test Device evaluates the physical properties and environmental resilience of electronic components, electrical enclosures, lighting fixtures, and related products under simulated precipitation conditions. Post-test verification enables performance assessment to support product design optimization, compliance validation, and quality assurance protocols.

This apparatus is engineered to UL60507-ENGL 1999 specifications (Figures 38.1, 38.2), ANSI Z21.10.3-2004 requirements, ANSI Z21.58 Figure 10/Figure 11 clauses, and CSA4.3-2004 standards. Compliance extends to UL1598, UL153, UL154B, UL1703, UL8750, UL1741, UL514B, UL1278, UL1571, and related certification protocols.

The nozzle assembly conforms to UL60507-ENGL 1999, UL484-34, ANSI Z21.10.3-2004, ANSI Z21.58, ANSI B94.11M, and CSA4.3-2004 dimensional and performance criteria.

Technical Specifications:

• Designed for UL precipitation testing and 45-degree sprinkler evaluation per applicable standards
• Modular construction comprising: UL Water Spray Test Device (three UL-compliant nozzles, upper assembly) and UL Sprinkler Test Device (single UL-compliant nozzle, lower assembly)
• Extruded aluminum frame provides structural stability and facilitates maintenance
• Adjustable nozzle mounting assembly with manual stainless steel elevation mechanism
• Genuine UL laboratory-grade nozzles ensure measurement traceability
• Mobile base assembly with locking casters for laboratory positioning
• Integrated pressure monitoring via domestic “Red Flag” brand stainless steel gauges (individual nozzle instrumentation)
