Overview

The OK-LY Series Splash Water Aging Test Chamber is an engineered environmental simulation system designed to evaluate the ingress protection (IP) performance of electronic enclosures, automotive lighting assemblies, signal devices, and industrial control housings under controlled dynamic water exposure conditions. Based on the principle of oscillating pipe-based water projection—where calibrated nozzles mounted on a motor-driven swing arm deliver reproducible water impact at defined angles and flow rates—the chamber replicates real-world splash, light rain, and intermittent wetting scenarios encountered during transportation, field operation, or storage. Unlike static immersion or drip tests, this apparatus subjects test specimens to directional, momentum-driven water impingement while rotating the sample platform, thereby simulating non-uniform exposure patterns critical for validating sealing integrity, gasket resilience, and material hydrophobicity degradation over time.

Key Features

• Robust dual-layer chamber construction: 1.2 mm cold-rolled A3 steel outer shell with electrostatic powder coating; interior lined with corrosion-resistant SUS304 stainless steel.
• High-efficiency thermal insulation: Composite layer of rigid polyurethane foam (≥30 mm thick) and fiberglass blanket, minimizing thermal loss and condensation during prolonged cycling.
• Precision oscillating pipe mechanism: Stepper-motor-driven swing arm with programmable angular range (±45° to ±180°), enabling strict adherence to IPX3 (oscillating 60° arc) and IPX4 (full 180° sweep) test profiles per IEC 60529.
• Stainless-steel and brass wetted components: All water-contact parts—including nozzles, manifolds, and reservoir fittings—are constructed from non-corrosive materials to ensure long-term hydraulic stability and prevent mineral deposition.
• Intelligent water management: Integrated German high-pressure pump with inline heating element, digital flow meter, and dual-stage particulate filtration (5 µm + 1 µm) to maintain nozzle integrity and consistent spray uniformity across extended test durations.
• Operator-centric control architecture: Optional full-color TFT touchscreen HMI (developed in-house) or configurable programmable logic controller (PLC) with real-time monitoring, alarm logging, and password-protected parameter editing—designed for GLP-compliant audit trails.
• Low-noise, energy-efficient operation: Frequency-inverter-controlled turntable and pump systems reduce acoustic emissions (<65 dB(A)) and power consumption by up to 22% compared to fixed-speed alternatives.

Sample Compatibility & Compliance

The OK-LY chamber accommodates specimens up to 800 mm × 800 mm × 800 mm (standard) or 1000 mm × 1000 mm × 1000 mm (custom), with adjustable PVC-coated turntable height and centering fixtures for asymmetric automotive headlamp assemblies. It satisfies the mechanical and procedural requirements of multiple international standards including: IEC 60529 (IPX3/IPX4), ISO 20653 (road vehicle ingress protection), MIL-STD-810G Method 506.6 (rain and blowing rain), GB/T 4208 (Chinese national IP code standard), GB/T 2423.38 (environmental testing—water resistance), and GJB 150.8 (Chinese military standard for rain exposure). All test cycles are traceable to calibrated flow meters and angular position encoders, supporting ISO/IEC 17025-accredited laboratories requiring documented uncertainty budgets.

Software & Data Management

The optional touch-based control system features embedded Linux OS with deterministic real-time scheduling, enabling synchronized coordination of oscillation angle, turntable speed, spray duration, and dwell intervals. Data logging records timestamped values for water flow rate (L/min), system pressure (bar), chamber ambient temperature (°C), and operational status every 2 seconds. Export formats include CSV and PDF reports compliant with FDA 21 CFR Part 11 requirements—supporting electronic signatures, user access levels, and immutable audit logs. Remote diagnostics via Ethernet port allow OEM service engineers to perform firmware updates and calibration verification without physical site visits.

Applications

This chamber is routinely deployed in R&D validation labs, automotive Tier-1 supplier QC departments, and third-party certification bodies for: evaluating sealant adhesion durability under cyclic thermal–hydraulic stress; verifying IP rating claims prior to UL/CE marking; assessing lens fogging and internal condensation behavior in LED headlamps; screening conformal coating effectiveness on PCBs exposed to coastal humidity; and qualifying junction box enclosures for outdoor renewable energy installations. Its modular design permits integration with external climate chambers for combined temperature–splash testing per ISO 16750-4.

FAQ

What standards does the OK-LY chamber specifically support for IPX3 and IPX4 validation?

It implements the exact nozzle configuration, flow rate (10 ± 5 L/min per nozzle), oscillation speed (120°/s), and specimen rotation (1 rpm) specified in IEC 60529 Annex B and ISO 20653 Clause 6.3.

Can the chamber be integrated into an automated test cell with MES or LabVantage?

Yes—its RS485 Modbus RTU and Ethernet TCP/IP interfaces enable bi-directional communication with manufacturing execution systems for job dispatch, pass/fail flagging, and SPC data ingestion.

Is compressed-air drying included after each test cycle?

An optional post-test purge module delivers regulated dry air (≤−40°C dew point) through the same nozzle manifold to accelerate surface moisture removal and prevent residual water pooling.

How is nozzle clogging prevented during long-duration reliability testing?

The dual-stage filtration system, combined with automatic 30-second air-blast cleaning after each cycle and scheduled ultrasonic nozzle maintenance protocols, ensures >99.2% nozzle uptime over 2,000-hour continuous operation.

Does the system provide NIST-traceable calibration documentation?

Each unit ships with factory calibration certificates for flow meter (±1.5% FS), angular encoder (±0.2°), and pressure transducer (±0.5% FS), all traceable to NIST or DAkkS-accredited reference standards.
