Introduction to Salt Spray Testing
Corrosion resistance is a critical performance criterion for materials and components exposed to harsh environmental conditions. Salt spray testing, standardized under ASTM B117, ISO 9227, and other international protocols, simulates accelerated corrosive environments to evaluate material durability. Industries such as automotive electronics, aerospace, and consumer electronics rely on salt spray chambers to predict long-term corrosion behavior, ensuring compliance with stringent quality and safety standards.
The LISUN YWX/Q-010 and YWX/Q-010X salt spray chambers are precision-engineered instruments designed to meet these rigorous testing demands. These systems provide controlled saline mist exposure, enabling manufacturers to assess protective coatings, metallic finishes, and electronic enclosures under standardized conditions.

Testing Principles and Methodology
Salt spray testing operates on the principle of controlled saline mist deposition, accelerating oxidation and galvanic corrosion. The LISUN YWX/Q-010 series employs a pneumatic atomization system to generate a uniform salt fog, ensuring consistent test conditions.
Key Testing Phases:
- Solution Preparation – A 5% sodium chloride solution (pH 6.5–7.2) is prepared per ASTM B117.
- Chamber Stabilization – Temperature and humidity are maintained at 35°C ± 2°C and ≥95% RH.
- Exposure Cycle – Components are subjected to continuous or cyclic spray, with durations ranging from 24 to 1,000 hours.
- Post-Test Evaluation – Specimens are inspected for rust, blistering, or coating degradation using visual or electrochemical analysis.
Industry Applications and Use Cases
1. Automotive Electronics
Automotive connectors, PCB coatings, and sensor housings undergo salt spray testing to ensure resilience against road salt and humidity. The YWX/Q-010X is widely used by Tier-1 suppliers to validate components per SAE J2334.
2. Aerospace and Aviation Components
Aluminum alloys and titanium fasteners are tested for pitting and crevice corrosion. The chamber’s precise humidity control ensures compliance with DO-160G Section 14.
3. Electrical and Electronic Equipment
Enclosures for industrial control systems and telecom equipment must resist saline atmospheres in coastal installations. The YWX/Q-010 verifies IP-rated housings per IEC 60529.
4. Medical Devices
Surgical instruments and implantable devices are assessed for biocompatibility and corrosion resistance under ISO 10993-15.
5. Consumer Electronics
Smartphones, wearables, and charging ports are tested to prevent galvanic corrosion between dissimilar metals.
Competitive Advantages of the LISUN YWX/Q-010 Series
- Precision Control – Digital PID controllers minimize temperature fluctuations (±0.5°C).
