Tell us the exact ingress level, governing standard, specimen size, and whether you need drip, spray, jet, pump, or turntable support.
Liquid Ingress Testing for Drip, Spray, and Water Jet Exposure
Liquid ingress testing is used to verify how an enclosure or product performs under controlled water exposure. Depending on the required rating or test method, the equipment may need to create vertical dripping water, tilted dripping water, spraying water, splashing water, or water jets at defined nozzle size and pressure.
ED&D’s liquid ingress equipment family includes drip boxes, combo drip box and spray chambers, rain spray apparatus, handheld spray nozzles, oscillating tube systems, water jet nozzles, water reservoirs and pump systems, and motorized turntables for specimen rotation. Together, these products support test programs tied to IEC 60529, EN 60529, IEC 60335, UL 1703, UL 50E, NEMA 4, NEMA 4X, and MIL-STD-810G.
Because ingress testing is highly method-specific, the correct system depends on the exact IPX level, spray or jet configuration, specimen dimensions, rotation requirements, and water supply / pressure requirements of the governing procedure.
Important standards note: the equipment must match the exact method. Nozzle geometry, oscillation angle, flow rate, specimen support, and pressure conditions all matter.

Frequently Asked Questions
What is the difference between drip, spray, and jet testing?
Drip testing evaluates vertical or tilted dripping water exposure, spray testing evaluates spraying or splashing water, and jet testing evaluates directed water jets at defined nozzle size and pressure.
When should a lab use a handheld spray nozzle instead of an oscillating tube?
That depends on the exact method. Some procedures call for a handheld nozzle arrangement, while others require an oscillating tube with defined radius, angle, and oscillation timing.
What is the difference between JET-03 and JET-03/6K?
JET-03 is positioned for IPX5 / IPX6 jet testing, while JET-03/6K adds high-pressure capability and the nozzle / pressure configuration needed for IPX6K-style workflows.
Why would a lab need a separate water reservoir and pump system?
Dedicated reservoir and pump systems help produce the required pressure and water delivery stability for repeatable jet testing, especially for higher-pressure methods.
What is the purpose of an ingress-test turntable?
A turntable rotates the specimen during water exposure so the enclosure is challenged more consistently around its perimeter or in a defined continuous-rotation method.
Does one liquid ingress setup cover all IPX levels?
Not usually. Different ingress levels often require different equipment such as drip boxes, combo chambers, spray nozzles, oscillating tubes, jet nozzles, and compatible water supply systems.
Send the exact standard and ingress level, plus specimen size and desired test configuration, and we can help narrow the right system.
Typical Liquid Ingress Test Applications
ED&D liquid ingress systems are used in electrical safety laboratories, enclosure verification programs, product certification test labs, military and ruggedized product workflows, and engineering development environments where controlled water exposure must be applied repeatably.
Depending on the equipment and method, these workflows may relate to IEC 60529, EN 60529, IEC 60335, UL 1703, UL 50E, NEMA 4, NEMA 4X, and MIL-STD-810G.
- IPX1 / IPX2 drip testing
- IPX3 / IPX4 spray and splashing-water testing
- IPX5 / IPX6 / IPX6K jet exposure testing
