Overview
The FQY Series Salt Spray Test Chamber is an engineered environmental test system designed for accelerated corrosion evaluation of metallic substrates, protective coatings, electroplated finishes, painted surfaces, and electronic components under controlled saline mist conditions. Operating on the principle of continuous or cyclic salt fog exposure—where atomized sodium chloride (NaCl) solution is introduced into a thermally stabilized chamber—the system replicates aggressive coastal or industrial atmospheric environments to assess material durability and coating integrity over defined test durations. The chamber complies with internationally recognized corrosion testing standards including ISO 9227 (Salt Spray Testing), IEC 60068-2-11 (Kb), ASTM B117 (Standard Practice for Operating Salt Spray (Fog) Apparatus), and GB/T 2423.17 (Chinese national standard equivalent to IEC 60068-2-11). Its robust stainless-steel construction, precision temperature control, and calibrated spray nozzle assembly ensure high reproducibility across sequential test cycles—critical for quality assurance in automotive, aerospace, electronics manufacturing, and surface treatment industries.
Key Features
- Stainless steel 316L inner chamber and cabinet structure for long-term resistance to chloride-induced pitting and stress corrosion cracking
- Dual-mode operation: Continuous salt spray (NSS/ASS/CASS) and optional programmable cyclic corrosion testing (CCT) capability via external controller integration
- Precision PID-controlled heating system maintaining chamber temperature within ±0.5 °C fluctuation and ±2 °C uniformity across full working volume
- Calibrated air-saturated salt fog generation using compressed air pre-heated and humidified to prevent nozzle clogging and ensure stable deposition rate of 1–2 mL/80 cm²·h
- Independent salt solution reservoir with level sensor and overflow protection; corrosion-resistant PVC piping and glass-reinforced nylon nozzles
- Integrated safety interlocks including low-water cutoff, overtemperature protection, and chamber door open detection
- Modular design supporting field-upgradable accessories: humidity control module, CO₂ injection kit, and condensation monitoring sensor
Sample Compatibility & Compliance
The FQY chamber accommodates specimens up to 640 mm deep × 1000 mm wide × 500 mm high (FQY030 model), enabling evaluation of large-format PCB assemblies, automotive trim parts, fasteners, and coated metal panels. Specimen racks are adjustable and constructed from inert PVC or polypropylene to eliminate interference during testing. All models meet essential requirements for regulatory compliance: ISO 9227 defines the operational parameters for neutral salt spray (NSS), acetic acid salt spray (AASS), and copper-accelerated acetic acid salt spray (CASS) tests; GB/T 2423.17 aligns with IEC 60068-2-11 for environmental testing methodology. For GLP/GMP environments, optional audit trail logging and user access control modules support 21 CFR Part 11 compliance when paired with validated software platforms.
Software & Data Management
While the base FQY unit operates via analog/manual controls, it supports digital upgrade paths through RS485/Modbus RTU interface for integration with centralized laboratory information management systems (LIMS) or SCADA networks. Optional touchscreen HMI controllers provide real-time display of chamber temperature, elapsed test time, and spray cycle status—with configurable alarm thresholds and event logging. Data export is supported in CSV format for traceability and statistical process control (SPC) analysis. Firmware updates maintain alignment with evolving test standard revisions (e.g., ISO 9227:2022 amendment on nozzle calibration procedures).
