LIB transforms its standard water spray / rain test chambers into fully customized solutions that meet Ford CETP 00.00-E-412, SAE J575 and JIS D0203 water ingress requirements - including high-pressure spray, multi-nozzle showers, light sprays and precision drip tests. Learn how our modular high-pressure water spray chamber and IPX waterproof test chamber options deliver repeatable, certified results.
When automotive OEMs or Tier-1 suppliers ask for water ingress testing that conforms to Ford CETP 00.00-E-412, SAE J575 or JIS D0203, they're asking for more than a standard rain cabinet. These standards include wildly different test conditions - from short bursts of extremely high-pressure spray to long duration multi-nozzle showers, to fine-droplet drip tests - often all at elevated temperatures such as 85°C.
LIB's approach to rain test chamber customization is modular, engineering-driven, and focused on repeatability so you can run Ford-grade and SAE/JIS tests on the same platform.
Test scenarios LIB addresses
- Scenario A (High-pressure spray) - 85 kgf/cm² (≈1220 psi) using 1–2 nozzles, 1000 L/hr for 2 minutes at 85°C. (Ford CETP 00.00-E-412)
- Scenario B (Heavy shower) - 40 × Ø1.2 mm nozzles at 3 kgf/cm², 39.2 L/min total for 1 hour at 85°C. (SAE J575 / JIS D0203)
- Scenario C (Light shower) - 2 × Ø0.5 mm nozzles at 3 kgf/cm², 3.2 L/min total for 10 minutes at 85°C. (SAE J575 / JIS D0203)
- Scenario D (Drip test) - 2 drops/sec for 1 hour at ambient temperature. (Ford CETP 00.00-E-412)
These different tests require different hydraulics, mechanical fixtures and control logic - which is why one-size-fits-all off-the-shelf chambers commonly fall short.
How LIB customizes: modular hardware + intelligent controls
High-pressure water spray chamber module (for Scenario A)
To reproduce 85 kgf/cm² conditions safely and repeatably, LIB supplies a dedicated high-pressure pump package, reinforced stainless steel piping and purpose-built nozzle mounts.
The nozzle fixture is lockable at 90° and adjustable so the DUT can be oriented to expose "the most severe spray angle." Integrated pressure sensors, over-pressure relief and safety interlocks protect the DUT and operators while logging the test for traceability. The LIB IPX9K Test Equipment can also conduct high-pressure water spraying tests. The difference is that the water temperature for this test should be 80℃, while the customer requires the temperature inside the chamber to be 85℃.
Multi-nozzle shower panel and flow balancing (for Scenario B)
For heavy showers LIB installs a modular 40-nozzle array with calibrated orifices (Ø1.2 mm) and a precision splitting manifold. Each branch is monitored using inline flow meters so the total 39.2 L/min distribution and per-nozzle uniformity are verifiable.2. This is similar to the L-shaped nozzle of the LIB JIS D0203 Rain Test Chamber.
The system includes a heated circulation tank and filtration/anti-scaling features to reliably supply 85°C water for long duration tests.
Quick-change nozzle modules & programmatic control (for Scenario C)
Switching from heavy shower to light spray is handled by quick-swap nozzle modules (Ø0.5 mm) and PLC-driven pressure control.
Pre-programmed test recipes allow operators to run a 10-minute light spray exactly to spec with automated data capture and pass/fail logging.
Precision drip generator (for Scenario D)
A micro-valve or calibrated capillary dropper module produces stable droplet rates (2 drops/sec) and is validated with optical counting sensors. The drip test fixture is low-disturbance and can lock DUT orientation so that repeatability and photographic records are easy to collect.The LIB IPX1 X2 Water Spray Test Chamber can also offer a water droplet test.
Built for 85°C operation and long-term reliability
Testing at elevated temperatures adds material and safety challenges. LIB addresses these by specifying high-temperature-rated seals, pump cooling and electrical isolation, heated circulation tanks built with corrosion-resistant materials, and sensor suites rated for high temp / high humidity. Every custom chamber receives a full calibration report for pressure, flow and temperature before shipment.
Validation, documentation and on-site support
LIB delivers each custom system with:
- Factory calibration certificates for pressure, flow and temperature.
- A recorded factory acceptance test (FAT) demonstrating each scenario (A–D).
- Detailed user manuals, maintenance guides and spare-parts lists.
- On-site installation, commissioning and operator training services so your lab reproduces the standard exactly.
Why choose LIB for rain test chamber customization?
LIB's strength is delivering modular, engineering-led customizations on a proven water spray chamber platform. Instead of buying multiple standalone rigs, customers get a compact, configurable water spray chamber that covers Ford CETP, SAE J575 and JIS D0203 workloads - saving floor space, reducing capex and simplifying test workflows.
Call to action
Ready to validate your DUT against Ford CETP 00.00-E-412, SAE J575 or JIS D0203? LIB can provide two levels of proposals:
1. Economy retrofit - upgrade a standard rain test chamber with swap-out nozzle panels and a heated circulation loop.
2. Full custom system - dedicated high-pressure pump train, calibrated multi-nozzle arrays, precision drip module, custom fixtures, factory validation report and on-site commissioning.
Reply with your DUT dimensions and preferred test scenarios (A/B/C/D) and we'll prepare a technical proposal and budget estimate.
