Overview
The OK-SC-500C Sand and Dust Test Chamber is an engineered environmental simulation system designed to evaluate the ingress protection (IP) performance, surface abrasion resistance, and functional reliability of industrial products under controlled airborne particulate exposure. It operates on the principle of forced-air suspension and directional particle delivery—mimicking natural desert, roadside, or industrial dust environments through precise regulation of airflow dynamics, particulate concentration, and particle kinetic energy. The chamber complies with internationally recognized test methodologies for IP5X (protection against limited dust ingress) and IP6X (complete dust-tightness), as defined in IEC 60529 and GB/T 4208. Its dual-mode capability—low-velocity dust suspension (for IP5X evaluation) and high-velocity sand projection (for IP6X and erosion testing)—enables comprehensive assessment of sealing integrity, optical surface durability, coating adhesion, and long-term operational stability under abrasive conditions.
Key Features
- Stainless steel inner chamber constructed from SUS 304 grade material, ensuring corrosion resistance, structural rigidity, and ease of particulate residue removal.
- Dual-sealed observation window with anti-scratch tempered glass and redundant silicone gasketing to prevent leakage during extended test cycles.
- Programmable high-pressure centrifugal blower system delivering stable, adjustable air velocity from 0 to 29 m/s, calibrated per ISO 5167 and traceable to NIST-traceable anemometry standards.
- Automated volumetric dust dosing mechanism using precision vibratory feeders and calibrated mesh sieving (per ASTM E11), enabling repeatable concentration control across the full operational range (0.1–10.6 g/m³ ±7%).
- Integrated rotating sample turntable (optional configuration), motor-driven with variable speed control (0.1–10 rpm), essential for uniform exposure in IP6X validation per IEC 60529 Clause 14.2.3.
- PLC-based control architecture with 7-inch industrial touchscreen HMI, supporting multi-step programmable profiles, real-time parameter logging, and USB data export compliant with GLP audit requirements.
- High-efficiency particulate air (HEPA) filtration system (H13 class, ≥99.95% @ 0.3 µm) installed in recirculation ductwork, preventing ambient contamination during chamber opening and meeting OSHA 29 CFR 1910.1200 hazard communication requirements.
Sample Compatibility & Compliance
The OK-SC-500C accommodates samples up to 500 L internal volume (W×D×H: 800×700×900 mm), suitable for automotive lighting assemblies, ADAS sensors, outdoor telecom enclosures, consumer electronics housings, and military-grade connectors. It supports both powered and unpowered test configurations with dedicated cable ports and grounding provisions. Regulatory compliance includes full alignment with IEC 60529 (IP5X/IP6X), ISO 20653 (road vehicles), MIL-STD-810G/H Method 510.5 (sand and dust), and GJB 150.12A (Chinese military standard). Calibration certificates for airflow velocity, concentration monitoring, and temperature uniformity (when equipped with optional thermal integration) are available upon request and conform to ISO/IEC 17025-accredited laboratory practices.
Software & Data Management
The embedded control software provides ISO 17025-aligned data integrity features, including user-level access control, electronic signature support, and time-stamped audit trails for all parameter changes and cycle executions. Test logs—including real-time wind speed, dust concentration (via gravimetric sampling port), elapsed time, and alarm events—are stored internally for ≥30 days and exportable in CSV format for integration into enterprise quality management systems (QMS). Optional Ethernet connectivity enables remote monitoring via Modbus TCP or OPC UA protocols, facilitating centralized lab management and FDA 21 CFR Part 11-compliant electronic record retention when paired with validated third-party QMS platforms.
Applications
- IP rating verification for automotive components (headlamps, radar housings, battery enclosures) per ISO 20653.
- Evaluation of optical lens haze and reflectance degradation due to silica abrasion in UAV sensors and surveillance cameras.
- Validation of gasket compression set and seal fatigue under cyclic dust loading in outdoor power distribution cabinets.
- Functional endurance testing of handheld medical devices exposed to hospital-grade particulate environments.
- Material screening for protective coatings used in aerospace avionics cooling ducts subjected to desert airstreams.
- Pre-compliance screening for MIL-STD-810G/H and GJB 150.12A certification prior to formal third-party testing.
FAQ
What standards does the OK-SC-500C fully support for IP6X testing?
It meets the mechanical and procedural requirements of IEC 60529 Clause 14.2.3 for dust-tightness verification, including rotational sample exposure at specified velocity and concentration thresholds.
Can the chamber be integrated with temperature/humidity control?
Yes—optional thermal subsystems (−20°C to +80°C, 10–95% RH non-condensing) are available as factory-integrated modules, enabling combined sand-dust + climatic stress testing per MIL-STD-810G/H Method 510.5 and ISO 16750-4.
Is gravimetric dust concentration measurement included?
A calibrated gravimetric sampling port is standard; users may perform periodic manual concentration verification per ISO 12103-1 A2 test dust protocol using certified analytical balances.
What maintenance intervals are recommended for the HEPA filter and blower assembly?
HEPA filters require replacement every 500 operational hours or after 10 full IP6X cycles; blower motor lubrication and impeller inspection are advised every 1,000 hours per OEM service manual.
Does the system include documentation for ISO/IEC 17025 traceability?
Factory calibration reports—including airflow velocity (NIST-traceable hot-wire anemometer), temperature uniformity (per IEC 60068-3-5), and dimensional verification—are provided with each unit shipment.
