Overview
The CORROSIONBOX COFOMEGRA Salt Spray Test Chamber is an engineered environmental test system designed for standardized corrosion resistance evaluation of metallic and coated materials under accelerated saline conditions. Built to comply with internationally recognized test protocols—including ASTM B117, ISO 9227, JIS Z2201, and DIN 50021—the chamber utilizes precision-controlled atomization of sodium chloride (NaCl) solution to generate a continuous, uniform salt fog environment within the test chamber. The system operates at a stabilized saturation temperature of 35 °C (±2 °C) and maintains pH-controlled brine delivery to ensure repeatability across test cycles. Its robust stainless-steel construction, integrated air saturation tower, and calibrated spray nozzle array enable high reproducibility in both neutral salt spray (NSS) and acetic acid salt spray (AASS) testing modes. Optional SO₂ gas integration—via the D200 PANEL variant—supports Kesternich testing (DIN 50018), enabling cyclic corrosion assessment for automotive, aerospace, and infrastructure components subjected to industrial or urban atmospheric exposure.
Key Features
- Four scalable chamber configurations: D200 (300 L), D600 (600 L), and D1000 (1000 L) models—each featuring seamless 316L stainless-steel interior walls and corrosion-resistant insulation.
- Digitally regulated temperature control (ambient to 55 °C) with PID feedback loop and independent chamber/saturation tower monitoring.
- Adjustable salt fog deposition rate (1.0–2.0 mL/80 cm²/h), verified via calibrated collection funnels per ASTM B117 Annex A1.
- Dedicated SO₂ injection module (D200 PANEL option) for Kesternich testing: precise mass-flow-controlled SO₂ dosing (0.2–2 L/day) at 0.2 bar pressure, compliant with DIN 50018 requirements.
- Integrated air filtration system (4 m pre-assembled line) with coalescing and activated carbon stages; optional deionized water filtration unit included on all base models.
- Modular test fixtures: adjustable rod-type specimen holders (4–6 units), standardized test plate racks (2–4 positions), and removable floor trays for easy residue management.
Sample Compatibility & Compliance
The COFOMEGRA chamber accommodates flat panels, fasteners, electronic enclosures, painted substrates, galvanized steel, aluminum alloys, and polymer-coated components up to 1700 mm × 900 mm × 690 mm (D1000 internal dimensions). All models meet CE marking requirements under the EU Machinery Directive 2006/42/EC and Electromagnetic Compatibility Directive 2014/30/EU. Test methodology alignment includes full traceability to ISO/IEC 17025-accredited laboratory practices. Optional audit-ready documentation packages support GLP-compliant validation, including IQ/OQ protocols and calibration certificates for temperature sensors, pressure transducers, and flow meters.
Software & Data Management
While the base COFOMEGRA configuration features analog/manual operation for regulatory simplicity, optional digital controllers provide real-time logging of chamber temperature, saturation tower temperature, spray duration, and cumulative test hours. Data export is available via USB or RS-485 interface in CSV format. For laboratories requiring compliance with FDA 21 CFR Part 11, validated PC-based software (sold separately) enables user access control, electronic signatures, and full audit trail functionality—including modification history for setpoints and alarm events.
Applications
- Automotive OEMs and Tier-1 suppliers evaluating paint adhesion, electroplated finishes, and zinc-nickel coatings on chassis components.
- Aerospace manufacturers assessing corrosion performance of magnesium and titanium alloys under simulated coastal service conditions.
- Electronics manufacturers validating conformal coating integrity on PCB assemblies exposed to high-humidity saline environments.
- Construction material producers testing galvanized rebar, stainless fasteners, and architectural cladding systems per EN ISO 12944.
- Research institutions conducting comparative studies on inhibitor efficacy in anti-corrosion formulations.
FAQ
What standards does the COFOMEGRA chamber support?
ASTM B117 (Neutral Salt Spray), ISO 9227 (NSS/AASS/CASS), JIS Z2201, DIN 50021, and DIN 50018 (Kesternich with SO₂) — with optional hardware and calibration kits.
Is deionized water mandatory for operation?
Yes. Only deionized or distilled water with conductivity ≤ 5 µS/cm is permitted in the brine reservoir and humidification system to prevent nozzle clogging and chamber contamination.
Can the chamber operate unattended for extended cycles?
All models include over-temperature cut-off, low-water-level shutoff, and door-open safety interlock. Continuous operation up to 1,000 hours is supported when paired with scheduled maintenance and periodic brine replenishment.
What electrical supply is required?
Single-phase 230 V AC ±10%, 50–60 Hz, with dedicated circuit protection (4–10 A depending on model); no three-phase input is needed.
Does the system include calibration documentation?
Factory calibration certificates for temperature sensors and pressure regulators are supplied with each unit; annual recalibration services are available through authorized European service centers.
