OK LS-810 Advanced Rain Test Chamber for IPX3–IPX6 Ingress Protection Validation

Overview

The OK LS-810 Advanced Rain Test Chamber is an engineered environmental test system designed to rigorously evaluate the liquid ingress protection performance of enclosures and finished products in accordance with IEC 60529 (equivalent to GB 4208 and ISO 20653). It replicates controlled rain exposure conditions across IPX3 (oscillating pipe), IPX4 (splashing water from any direction), IPX5 (low-pressure water jet), and IPX6 (powerful water jet) test configurations—enabling comprehensive validation of sealing integrity, material resistance to hydrostatic stress, and functional reliability under simulated outdoor precipitation environments. Unlike basic drip or static spray units, the LS-810 integrates programmable oscillation mechanics, calibrated high-flow nozzles, adjustable wind-assisted rainfall dynamics, and precision thermal regulation—allowing laboratories to reproduce realistic field-relevant wetting scenarios including wind-driven rain, intermittent showers, and sustained downpour. Its architecture supports both stationary and rotating sample mounting, ensuring uniform exposure per standard-defined angular coverage requirements.

Key Features

• Multi-mode IP rating compliance: Fully configurable for IPX3 (120° or 180° oscillating pipe), IPX4 (multi-angle splash simulation), IPX5 (6.3 mm nozzle, 12.5 L/min ±0.625 L/min at 2.5–3 m distance), and IPX6 (12.5 mm nozzle, 100 L/min ±5 L/min)
• Precisely regulated rainfall intensity: Adjustable from 10 to 20 cm/h via calibrated flow control valves and multi-stage centrifugal pump system
• Droplet size control: Nozzle arrays engineered to generate droplets within 0.5–4.5 mm diameter range, consistent with natural rainfall spectra referenced in MIL-STD-810G Method 506
• Integrated wind simulation: Programmable axial airflow (5–18 m/s) to replicate wind-driven rain dynamics critical for automotive lighting, outdoor telecom cabinets, and marine electronics testing
• Thermally stabilized test environment: Chamber temperature controllable from ambient +10°C to 55°C, enabling combined thermal-rain stress evaluation per IEC 60068-2-68 and automotive OEM specifications
• Robust stainless-steel construction: Interior chamber fabricated from SUS304 stainless steel; exterior powder-coated carbon steel; integrated waterproof viewing window and LED illumination
• PLC-based control with 7-inch HMI touchscreen: Supports user-defined test profiles, cycle repetition, pause/resume functions, real-time parameter logging, and audit-ready event history

Sample Compatibility & Compliance

The LS-810 accommodates samples up to Ø600 mm diameter on a motorized turntable (1–5 rpm adjustable), with maximum load capacity of 100 kg. Its modular nozzle assembly and configurable pipe radius (standard R400–R1000 mm options available upon request) ensure compatibility with small electronic components (e.g., sensors, connectors) as well as large assemblies (e.g., EV charging stations, outdoor LED displays, vehicle ECUs). The system complies with mandatory test parameters defined in IEC 60529 Annex B, GB 4208, ISO 20653, and MIL-STD-810G/H Method 506. Optional calibration certificates traceable to national metrology institutes are available. For regulated industries, the controller supports GLP/GMP-compliant data integrity features—including password-protected parameter modification, electronic signature prompts, and 21 CFR Part 11–ready audit trails when paired with OK’s optional data archiving module.

Software & Data Management

The embedded control firmware enables full test automation: users define sequence steps (e.g., pre-conditioning soak → IPX3 oscillation → 10-min dwell → IPX6 jet exposure → post-test inspection hold), set tolerances for flow rate deviation (<±2%), and configure automatic safety interlocks (e.g., shutdown on low water level, overtemperature, or door open detection). All operational events—including start/stop timestamps, actual vs. setpoint values for rainfall intensity, wind speed, temperature, and elapsed time—are logged internally and exportable via USB to CSV format. Remote monitoring is supported via Ethernet interface using Modbus TCP protocol, facilitating integration into centralized lab management systems (LIMS) or MES platforms. Firmware updates are delivered via secure OTA mechanism with version rollback capability.

Applications

The LS-810 serves quality assurance and R&D labs across multiple sectors requiring validated ingress protection verification. In automotive electronics, it validates headlamp housings, ADAS sensor covers, and battery enclosure gaskets under dynamic rain-wind loading. Consumer appliance manufacturers use it to verify washing machine control panels, outdoor kitchen appliances, and robotic vacuum cleaners per IEC/EN 60335-1. Telecommunications providers deploy it for base station cabinets and fiber distribution hubs compliant with Telcordia GR-487-CORE. Lighting designers apply it to streetlight fixtures tested to IP66/IP67 thresholds. Additionally, the chamber supports custom test development for emerging standards such as ISO 16750-4 (road vehicles — environmental conditions) and UL 50E (enclosure ratings for industrial control equipment).

FAQ

Does the LS-810 meet IEC 60529 requirements for IPX5 and IPX6 testing?
Yes—the system includes calibrated 6.3 mm and 12.5 mm nozzles, pressure-regulated supply lines, and distance-constrained positioning jigs to satisfy all dimensional, volumetric, and temporal criteria specified in Clauses 14.2.5 and 14.2.6 of IEC 60529.
Can the chamber perform combined temperature and rain testing simultaneously?
Yes—temperature is independently regulated within the sealed chamber while rain/wind modules operate, enabling concurrent thermal-rain stress profiles per IEC 60068-2-68 and automotive OEM test plans.
Is water filtration included to prevent nozzle clogging?
Yes—a dual-stage filtration system (5 µm coarse + 0.45 µm fine membrane) is integrated upstream of all nozzles, with visual clog indicators and maintenance alerts.
What electrical supply is required for full IPX6 operation?
A dedicated 3-phase 380 V ±10%, 50 Hz supply with minimum 7.5 kW capacity is recommended to sustain continuous 100 L/min flow at required pressure.
Are calibration services and traceable documentation available?
OK Instruments provides factory calibration reports with NIST-traceable references for flow meters, pressure transducers, and temperature sensors; on-site recalibration and ISO/IEC 17025-accredited certification can be arranged.
