Overview
The OK-HC-800.021 IP5X/IP6X Sand and Dust Test Chamber is an engineered environmental simulation system designed to replicate controlled airborne particulate conditions in accordance with internationally recognized ingress protection (IP) test standards. It operates on the principle of forced-air suspension and directional particle delivery—utilizing high-efficiency centrifugal blowers, precision-calibrated dust dispersion nozzles, and closed-loop recirculation to maintain stable, traceable concentrations and velocities over extended test durations. This chamber supports both IP5X (dust-protected) and IP6X (dust-tight) evaluations as defined in IEC 60529 and GB/T 4208, enabling quantitative assessment of enclosure integrity, surface abrasion resistance, and functional reliability under simulated desert, industrial, or off-road operational environments.
Key Features
- Stainless steel inner chamber constructed from SUS 304 grade material for long-term corrosion resistance and ease of decontamination.
- Dual-layer silicone-sealed observation door with scratch-resistant tempered glass viewport, ensuring zero particulate leakage during operation.
- Programmable variable-speed rotating sample turntable (optional), essential for uniform exposure during IP6X sand impact testing.
- Integrated automatic dust dosing system using vibratory feeders and calibrated mesh sieves (80–200 µm), enabling repeatable and documented mass flow control.
- High-efficiency multi-stage filtration unit (HEPA + cyclonic pre-filter) installed in the recirculation path, preventing operator exposure and laboratory contamination upon chamber opening.
- PLC-based control system with 7-inch industrial touchscreen HMI, supporting user-defined test profiles, real-time parameter logging, and data export via USB or Ethernet.
- Safety interlocks including door-open shutdown, motor overcurrent protection, thermal cutoff, and blower overload monitoring—all compliant with IEC 61000-6-2 EMC requirements.
Sample Compatibility & Compliance
The OK-HC-800.021 accommodates samples up to 800 mm × 800 mm × 800 mm (W×D×H), making it suitable for automotive lighting assemblies, ECUs, outdoor telecom enclosures, consumer electronics housings, and industrial sensors. Its airflow architecture has been validated against ISO 20653 Annex B for vehicle-specific dust classification and meets the spatial uniformity requirements of MIL-STD-810H Method 510.5 for military-grade equipment qualification. All operational parameters—including concentration, velocity, and exposure duration—are traceable to NIST-traceable calibration certificates for pressure, flow, and mass measurement. The system supports full audit trails required under GLP and ISO/IEC 17025 laboratory accreditation frameworks.
Software & Data Management
The embedded control firmware records time-stamped values for all critical variables—including blower RPM, measured dust concentration (via gravimetric sampling ports), inlet/outlet temperature, and chamber pressure differential—at configurable intervals (1–60 s). Data files are stored in CSV format and include metadata such as test ID, operator name, standard reference, and calibration expiry dates. Optional software modules provide remote monitoring via Modbus TCP, integration with LIMS platforms, and automated report generation compliant with ASTM E29 and ISO/IEC 17025 clause 7.8.2. Audit trail functionality satisfies FDA 21 CFR Part 11 requirements for electronic records and signatures when enabled with user authentication and role-based access controls.
Applications
- Validation of IP5X dust ingress resistance for automotive connectors, camera housings, and battery management systems.
- Accelerated abrasion testing of optical lenses, display covers, and painted surfaces using calibrated silica sand at velocities up to 29 m/s.
- Functional verification of HVAC actuators, power inverters, and charge controllers under sustained dust loading conditions.
- Pre-compliance screening for CE marking, CCC certification, and UN ECE R100 electrical safety assessments.
- Supporting failure mode analysis (FMEA) by correlating particulate accumulation patterns with thermal derating or contact resistance degradation.
FAQ
What standards does this chamber fully support out-of-the-box?
IEC 60529 (IP5X/IP6X), GB/T 4208, ISO 20653 (road vehicles), MIL-STD-810H Method 510.5, and GJB 150.12A.
Can the chamber operate continuously for 72 hours without manual intervention?
Yes—designed for unattended operation with auto-replenishment logic for dust media and continuous filter monitoring.
Is gravimetric concentration verification included in the standard configuration?
Yes; two certified sampling ports (ISO 29463 Class H13 rated) are integrated for periodic filter-weight validation per ISO 12103-1 A2 test dust protocol.
Does the system support third-party calibration services?
All transducers (anemometers, load cells, thermistors) are fitted with standardized interfaces compatible with accredited metrology labs.
What maintenance schedule is recommended for long-term accuracy?
Biannual inspection of blower balance, quarterly replacement of primary cyclone liners, and annual recalibration of concentration sensors and velocity probes.
