Testing Principle
The UL Rain Test Spray Nozzle is used to direct a controlled water spray onto the test sample as part of a rain test or sprinkler test system. According to UL 60507 and related standards such as ANSI Z21.58 and CSA 4.3, the nozzle helps simulate rain and sprinkler conditions to evaluate whether water enters critical areas of luminaires and electrical products intended for wet locations.
This method supports accurate assessment of product sealing performance by delivering a consistent spray pattern under defined pressure and flow conditions, helping manufacturers verify compliance with UL requirements for products used in wet environments.
Common Error Mitigation
To obtain accurate and consistent test results when using the UL Rain Test Spray Nozzle, the following practices are recommended:
- Keep the nozzle orifice clean and free from blockage to maintain the required spray pattern and pressure.
- Verify that the water pressure remains stable at 34.5 kPa per spray head throughout the test.
- Ensure the nozzle is correctly installed and aligned according to the test system requirements.
- Use the appropriate nozzle type (spray or sprinkler) for the specific test position as defined in the standard.
- Regularly inspect the nozzle for wear or damage, especially when used frequently in laboratory testing.
Applications & Use Cases
The UL Rain Test Spray Nozzle serves as a reliable replacement accessory and component for UL rain test and water spray test systems. It helps lighting manufacturers, electrical product manufacturers, and testing laboratories maintain consistent test conditions when performing wet location testing according to UL 60507, ANSI Z21.58, CSA 4.3, and UL 1598.
This nozzle is commonly used by lighting manufacturers as a replacement part in wet location luminaire testing, by testing laboratories as a key component in UL 60507 and related water spray test setups, and by certification bodies to support standardized wet location compliance testing.
