Overview
The LabCompanion FQY Series Salt Spray Test Chamber is an engineered environmental test system designed to replicate aggressive saline atmospheric conditions for accelerated corrosion evaluation of metallic substrates, electroplated coatings, organic finishes, and electronic enclosures. Operating on the principle of controlled sodium chloride (NaCl) aerosol generation and uniform deposition within a thermally stabilized chamber, it enables standardized assessment of material resistance to chloride-induced degradation—critical for automotive, aerospace, marine, and electronics manufacturing sectors where long-term durability under coastal or de-icing salt exposure must be quantified prior to field deployment.
Key Features
- Corrosion-resistant chamber construction using high-grade PVC-coated steel or optional fiberglass-reinforced polymer (FRP) for extended service life in highly acidic chloride environments
- Precision-engineered spray tower and conical nozzles ensure consistent, gravity-driven fog distribution with minimal droplet coalescence—meeting ISO 9227 requirements for uniform deposition density across the test area
- Dual-zone thermal control architecture: primary chamber heating via open-wire resistive elements; saturated air preheating via stainless-steel immersion heaters in the humidity saturation tank—ensuring stable temperature and humidity coupling during NaCl mist generation
- Programmable cyclic operation mode supports alternating salt spray, dry, and humid phases per ASTM B117 modified protocols and ISO 14993 for multi-stress corrosion testing
- Digital PID temperature controller with integrated time-based relay logic for precise spray duration sequencing (e.g., 90-min spray / 30-min rest cycles)
- Over-temperature cutoff, audible/visual alarm indicators, and redundant safety interlocks compliant with IEC 61000-6-2 electromagnetic compatibility and Class I electrical safety standards
Sample Compatibility & Compliance
The FQY series accommodates flat panels, fasteners, PCB assemblies, and small structural components up to 1000 mm × 2000 mm × 900 mm (FQY160L model). Adjustable sample racks, standardized test rods (per ISO 9227 Annex A), and dedicated specimen holders allow reproducible orientation relative to fog flow direction. All models are validated against national and international regulatory frameworks including GB/T 2423.17 (China), IEC 60068-2-11 (IEC), ISO 9227 (corrosion testing—neutral, acetic acid, and copper-accelerated variants), and GB/T 10587 (chamber performance specification). Optional acetic acid (AASS) and copper sulfate–accelerated (CASS) test configurations extend applicability to high-sensitivity coating systems requiring rapid failure detection.
Software & Data Management
While base models utilize standalone digital controllers, LabCompanion offers optional RS485/Modbus RTU interface kits compatible with third-party SCADA platforms (e.g., Siemens Desigo, Ignition SCADA) for centralized environmental monitoring. Real-time logging of chamber temperature, spray cycle status, and elapsed test time supports GLP-compliant recordkeeping. Audit trails—including operator ID, parameter changes, and alarm events—can be exported in CSV format for FDA 21 CFR Part 11–aligned documentation when paired with validated electronic signature modules. Calibration certificates traceable to NIM (National Institute of Metrology, China) are provided upon delivery.
Applications
- Qualification testing of zinc-nickel, tin-zinc, and chromate conversion coatings per ASTM B633 and ISO 4520
- Validation of conformal coatings on printed circuit boards (IPC-CC-830B)
- Comparative corrosion resistance evaluation of aluminum alloys (e.g., 6061-T6 vs. 7075-T6) under simulated marine exposure
- Supplier audit support for automotive OEMs adhering to GMW14872, Ford CETP 00.00-L-467, and VW PV1210 specifications
- Research into inhibitor efficacy in anti-corrosion primers and self-healing polymer systems
FAQ
What standards does the FQY series comply with?
It fully conforms to GB/T 2423.17, IEC 60068-2-11, ISO 9227 (NSS, AASS, CASS), and GB/T 10587 for chamber performance verification.
Can the chamber operate in cyclic test modes?
Yes—programmable timers enable user-defined sequences of salt spray, dry-off, and high-humidity phases per ISO 14993 and ASTM G85 Annex A5.
Is calibration documentation included?
Each unit ships with a factory calibration report traceable to NIM, covering temperature uniformity, spray deposition rate, and timer accuracy.
What materials are used for internal chamber construction?
Standard configuration uses PVC-coated carbon steel; optional FRP or PP-lined chambers are available for extreme chemical resistance.
Does LabCompanion provide installation and validation support?
IQ/OQ documentation templates and on-site IQ execution services are available upon request for regulated laboratory environments.
