HAIDA HD-E808-120 Salt Spray Test Chamber

Overview

The HAIDA HD-E808-120 Salt Spray Test Chamber is an engineered environmental test system designed for standardized accelerated corrosion evaluation of metallic and coated materials under controlled saline aerosol exposure. It operates on the principle of continuous atomization of a precisely formulated salt solution—typically sodium chloride (NaCl) or copper-accelerated acetic acid (CASS)—into a saturated, temperature-regulated test chamber. This process simulates aggressive coastal or industrial atmospheric conditions to assess long-term corrosion resistance of surface treatments including electroplating, conversion coatings, organic paints, passivation layers, and rust inhibitors. As a core instrument in reliability engineering and quality assurance workflows, the HD-E808-120 supports compliance-driven validation per internationally recognized test protocols—including neutral salt spray (NSS), acetic acid salt spray (AASS), and copper-accelerated acetic acid salt spray (CASS)—enabling reproducible, auditable corrosion performance data for R&D, production QC, and regulatory submissions.

Key Features

• Corrosion-resistant construction: Inner chamber fabricated from 5 mm thick imported PVC板材 (Nanya Taiwan grade), rated for continuous operation up to 85 °C; transparent acrylic lid (5 mm European-grade PMMA) with 100° sealing angle to prevent condensate drip onto specimens.
• Precision fog generation: Bernoulli-effect spray system with borosilicate glass nozzles and conical dispersion tower ensures uniform droplet distribution (1.0–2.0 mL/80 cm²/h, averaged over ≥16 h) and eliminates nozzle clogging or crystallization.
• Dual independent temperature control: Digital PID controllers regulate both test chamber (RT–50 °C, ±0.1 °C accuracy) and air-saturation pressure tank (RT–50 °C), enabling rapid thermal stabilization and consistent fog saturation.
• Fail-safe operational architecture: Integrated fault-detection system with visual LED indicators and audible alarm for low water level, overtemperature, spray interruption, or power loss; automatic resume function retains elapsed test time after power recovery.
• Water-sealed chamber interface: Water-trap gasket design between inner chamber and lid prevents salt fog leakage, meeting ISO 9227 containment requirements and minimizing lab contamination risk.
• Modular fluid management: Dual auto/manual补水 system for chamber and pressure tank (connectable to municipal water supply); concealed 40 L salt solution reservoir with level gauge; manual drain valve for maintenance.
• Electrical safety compliance: IP54-rated control cabinet with dry-heater isolation, ground-fault circuit interrupter (GFCI), overcurrent protection, and grounding resistance <4 Ω per IEC 61000-4-5.

Sample Compatibility & Compliance

The HD-E808-120 accommodates test specimens up to 1200 mm (L) × 500 mm (W) × 1000 mm (H), mounted on adjustable 30° V-shaped stainless steel racks or flat multi-angle sample holders. Its design supports standard specimen orientation per ASTM B117 and ISO 9227, including vertical placement for coating adhesion assessment and angled positioning for crevice corrosion simulation. The chamber meets full technical and metrological requirements of multiple international standards: GB/T 2423.17–2008 (equivalent to IEC 60068-2-11), ISO 9227:2006, ASTM B117–2009, JIS H 8502, GB/T 10125–2012, and GJB 150.11A–2009. All critical parameters—including fog collection rate, nozzle pressure (1.00 ± 0.01 kgf/cm²), pH control (6.5–7.2 for NSS; 3.1–3.3 for CASS), and temperature uniformity (±1 °C)—are verifiable via internal calibration points and third-party verification protocols aligned with GLP and ISO/IEC 17025 laboratory practices.

Software & Data Management

While the HD-E808-120 operates via embedded hardware controls (no PC-dependent software), its digital interface provides traceable, audit-ready operational records essential for regulated environments. The dual-channel LCD controller logs real-time chamber and saturation tank temperatures, cumulative test duration (up to 9999 h), and event timestamps for spray initiation, power interruption, and fault triggers. All displayed values—including setpoints, actual readings, and alarm status—are retained in non-volatile memory. For integration into enterprise quality management systems (QMS), optional RS-485 or Modbus RTU interfaces enable connection to SCADA platforms or LIMS for automated data archiving. The unit supports 21 CFR Part 11-compliant documentation when paired with validated external logging hardware, fulfilling FDA, automotive OEM, and defense contractor requirements for electronic record integrity and operator accountability.

Applications

This chamber serves cross-industry corrosion validation needs: automotive component suppliers use it for evaluating zinc-nickel plating durability on brake calipers and fasteners; aerospace manufacturers qualify chromate conversion coatings on aluminum alloys per AMS 2410; electronics producers test conformal coating integrity on PCB assemblies under IPC-J-STD-001; and marine equipment fabricators validate stainless steel passivation per ASTM A967. It is routinely deployed in ISO 17025-accredited testing labs for certification against EN 13523 (coil-coated metals), ISO 1461 (hot-dip galvanizing), and MIL-DTL-16232 (military hardware finishes). Its stable fog output and thermal consistency make it suitable for comparative lifecycle modeling—e.g., correlating 96 h NSS exposure to 2+ years field service in humid subtropical climates.

FAQ

What standards does the HD-E808-120 fully comply with?
It meets the technical specifications and procedural requirements of ISO 9227:2006, ASTM B117–2009, GB/T 10125–2012, GB/T 2423.17–2008, JIS H 8502, and GJB 150.11A–2009—including fog collection rate, temperature stability, and pH control tolerances.
Can the chamber perform both NSS and CASS tests without modification?
Yes—its adjustable nozzle pressure, programmable temperature setpoints, and dual pH-compatible solution handling allow seamless transition between neutral (pH 6.5–7.2) and acidic (pH 3.1–3.3) salt spray modes using the same hardware configuration.
Is remote monitoring or data export supported?
The base model features local digital readouts only; however, RS-485/Modbus RTU output is available as a factory-installed option for integration with centralized lab data acquisition systems.
What maintenance intervals are recommended for long-term reliability?
Daily visual inspection of water levels and nozzle integrity; weekly cleaning of the fog collector and saturation tank; quarterly verification of temperature sensor calibration and seal integrity; annual replacement of the pressure relief valve and gasket set per preventive maintenance schedule.
Does the unit include documentation for IQ/OQ qualification?
Factory-supplied documentation includes a comprehensive User Manual, Factory Calibration Report (traceable to NIM China), Electrical Safety Certificate, and Standard Operating Procedure (SOP) templates compatible with GMP/GLP IQ/OQ protocols.
