OK LS-801 IPX5 Rain Test Chamber (Spray Gun Type)

Overview

The OK LS-801 IPX5 Rain Test Chamber is an engineered environmental test system designed to perform standardized ingress protection (IP) rating verification in accordance with IEC 60529 and GB 4208. It implements the IPX5 test protocol—defined as protection against water projected by a standard nozzle from any direction—using a calibrated spray gun system operating at precisely controlled flow rate (12.5 ± 0.625 L/min), pressure (typically 30–100 kPa), and distance (2.5–3.0 m). Unlike immersion or dripping tests, IPX5 evaluates mechanical resistance to low-pressure water jets, simulating real-world exposure scenarios such as heavy rain, hose-directed spray, or vehicle wash conditions. The LS-801 integrates a high-stability centrifugal pump, digital flow/pressure monitoring, motorized turntable, and adjustable gantry-mounted spray assembly to ensure repeatable, traceable, and standards-compliant testing. Its open-frame architecture supports large-format samples while maintaining full compliance with the geometric and temporal requirements of Clause 14.2.5 of IEC 60529.

Key Features

• Calibrated Φ6.3 mm brass nozzle assembly, supplied with verification gauge and ISO-traceable calibration documentation
• Stabilized hydraulic circuit featuring pressure-regulating valve, buffer tank, and dual-stage filtration (5 µm + 1 µm) to prevent nozzle clogging
• Digital flowmeter and precision pressure transducer with real-time on-screen display (±0.5% FS accuracy)
• Programmable turntable (Φ300–Φ600 mm, max load 100 kg) with speed control from 1–5 RPM and programmable dwell positioning
• Adjustable龙门 gantry structure enabling precise vertical/horizontal/lateral positioning of the spray nozzle within ±5 mm tolerance
• PLC-based control system with 7-inch HMI touchscreen interface supporting multi-step test sequences, data logging, and password-protected parameter management
• Integrated temperature control module (RT+10°C to 55°C) for combined thermal-rain testing per IEC 60068-2-68
• Optional wind simulation module (5–18 m/s laminar airflow) compliant with MIL-STD-810H Method 506.6 for dynamic environmental correlation

Sample Compatibility & Compliance

The LS-801 accommodates samples up to 1.2 m in height and 0.8 m in diameter when mounted on the standard turntable; custom turntables and extended gantries are available for oversized units including automotive lighting assemblies, outdoor telecom enclosures, and industrial control cabinets. All operational parameters—including flow rate, spray duration per surface (>60 s minimum), angular coverage (360° continuous rotation), and standoff distance—are validated against IEC 60529 Annex B and GB 4208 Clause 14.2.5. The system supports concurrent execution of IPX5 and optional IPX6 protocols via interchangeable nozzles (Φ6.3 mm and Φ12.5 mm), enabling dual-certification workflows without hardware reconfiguration. Test reports generated by the embedded controller include timestamped flow/pressure logs, operator ID, sample ID, and pass/fail status per surface zone—fully aligned with GLP audit requirements and FDA 21 CFR Part 11 electronic record integrity criteria.

Software & Data Management

The OK LS-801 runs on a deterministic real-time PLC kernel with embedded Ethernet (TCP/IP) and USB 2.0 interfaces. Its native OK-TestSuite software enables remote configuration, live parameter monitoring, and automated report generation in PDF/CSV formats. All test events—including pump start/stop, turntable motion, flow deviation alarms (>±2% setpoint), and emergency shutdown triggers—are recorded with microsecond timestamp resolution and stored in non-volatile memory for ≥10,000 cycles. Audit trails comply with ISO/IEC 17025:2017 Clause 7.9 and support retrospective review during regulatory inspections. Optional OPC UA server integration allows seamless data exchange with MES, LIMS, or QMS platforms such as Siemens Opcenter, LabVantage, or ETQ Reliance.

Applications

This chamber serves critical validation functions across multiple regulated and industrial sectors. In consumer electronics, it verifies enclosure integrity of smartphones, wearables, and smart home hubs prior to CE marking. For automotive suppliers, it validates headlamp housings, battery enclosures, and ADAS sensor modules per ISO 20653 and SAE J1927. Lighting manufacturers use it to qualify IP-rated LED streetlights and architectural fixtures under IEC 60598-1. Industrial equipment producers apply it to test control panels, HMIs, and motor drives destined for outdoor or washdown environments (e.g., food processing, wastewater treatment). Additionally, the LS-801 supports R&D-level parametric studies—such as correlating droplet size distribution (0.5–4.5 mm) and wind-assisted impingement angles with seal failure thresholds—enabling physics-informed design iteration.

FAQ

Does the LS-801 meet IEC 60529 IPX5 certification requirements?
Yes—the system is pre-validated for all mandatory parameters: Φ6.3 mm nozzle geometry, 12.5 ± 0.625 L/min flow rate, 2.5–3.0 m spray distance, 360° rotational coverage, and ≥60 s exposure per accessible surface.
Can it perform IPX6 testing as well?
Yes—by installing the optional Φ12.5 mm nozzle kit and adjusting flow setpoint to 100 ± 5 L/min, the same platform executes full IPX6 validation per IEC 60529 Clause 14.2.6.
What water quality is required to avoid nozzle blockage?
Deionized or softened water with total dissolved solids (TDS) < 50 ppm and particulate content < 1 µm is strongly recommended; integrated dual-stage filtration ensures robust operation even with municipal tap water.
Is the turntable speed adjustable during test execution?
Yes—speed can be modified in real time via HMI or external PLC command, allowing variable-rate rotation for asymmetric samples or accelerated coverage protocols.
How is test repeatability ensured across different operators?
Through role-based access control, parameter locking, automatic calibration reminders, and embedded digital signature capture for each test initiation—ensuring procedural consistency and regulatory defensibility.
