Introduction
Corrosion resistance testing is a critical quality assurance process across industries where material durability under harsh environmental conditions is paramount. Salt spray test chambers simulate accelerated corrosive environments to evaluate the protective coatings, finishes, and material integrity of components. This article provides a detailed comparison between LISUN’s YWX/Q-010 and YWX/Q-010X salt spray test chambers and comparable models from Ascott, focusing on technical specifications, testing methodologies, compliance with international standards, and industry-specific applications.
Technical Specifications and Design Comparison
LISUN YWX/Q-010 and YWX/Q-010X Overview
LISUN’s YWX/Q-010 and YWX/Q-010X are precision-engineered salt spray test chambers designed for accelerated corrosion testing. Both models comply with ASTM B117, ISO 9227, IEC 60068-2-11, and JIS Z 2371, ensuring broad applicability in regulated industries.

The YWX/Q-010X offers expanded functionality, including cyclic corrosion testing, making it suitable for industries requiring multi-phase environmental stress validation, such as automotive electronics and aerospace components.
Ascott Salt Spray Chambers: Key Models
Ascott’s comparable models, such as the SST 450 and SST 1000, are widely used in corrosion testing but differ in several technical aspects:
- Temperature Stability: Ascott chambers typically maintain ±2°C precision, slightly less stringent than LISUN’s ±1°C control.
- Material Durability: While Ascott utilizes PVC construction, LISUN’s YWX/Q-010X employs high-grade polypropylene (PP), offering superior resistance to prolonged chemical exposure.
- Automation: Ascott models often rely on manual calibration, whereas LISUN integrates automated spray and humidity control systems.
Testing Principles and Compliance with Industry Standards
Corrosion Testing Methodologies
Both LISUN and Ascott chambers perform neutral salt spray (NSS), acetic acid salt spray (AASS), and copper-accelerated acetic acid salt spray (CASS) tests. However, LISUN’s YWX/Q-010X supports cyclic corrosion testing, which alternates between salt spray, humidity, and drying phases—critical for automotive and aerospace applications where components face dynamic environmental stresses.
Standards Compliance
| Standard | LISUN YWX/Q-010 & 010X | Ascott SST Series |
|---|---|---|
| ASTM B117 | Fully compliant | Compliant |
| ISO 9227 | Fully compliant | Compliant |
| IEC 60068-2-11 | Fully compliant | Partial compliance (requires additional calibration) |
| JIS Z 2371 | Fully compliant | Compliant |
LISUN’s adherence to IEC 60068-2-11 without additional calibration provides an advantage in telecommunications and medical device testing, where regulatory scrutiny is stringent.
Industry-Specific Applications
Electrical and Electronic Equipment
In PCB coatings, connectors, and semiconductor housings, salt spray testing ensures resistance to corrosive atmospheres. LISUN’s ±1°C temperature stability ensures repeatable results for high-reliability components in industrial control systems.
Automotive Electronics
Automotive manufacturers require cyclic corrosion testing to simulate road salt, humidity, and thermal cycling. The YWX/Q-010X’s multi-phase testing capability aligns with SAE J2334, making it preferable over Ascott’s static spray chambers.
Aerospace and Aviation Components
Aircraft components undergo extreme environmental stress. LISUN’s PP construction resists degradation from prolonged salt exposure, whereas PVC-based Ascott chambers may require more frequent maintenance.
Medical Devices and Telecommunications
For implantable devices and 5G infrastructure, corrosion resistance is non-negotiable. LISUN’s compliance with IEC 60068-2-11 ensures validation under controlled humidity and salt deposition, critical for regulatory approvals.
Competitive Advantages of LISUN YWX/Q-010X
- Superior Material Durability: Polypropylene construction outperforms PVC in long-term chemical resistance.
- Advanced Control System: Touchscreen HMI with data logging enhances traceability for audits.
- Cyclic Testing Capability: Essential for automotive and aerospace validation.
- Stricter Temperature Control: ±1°C precision ensures higher repeatability.
Conclusion
While both LISUN and Ascott provide reliable salt spray test chambers, LISUN’s YWX/Q-010X offers technical superiority in material durability, testing flexibility, and compliance with rigorous industry standards. Its ability to perform cyclic corrosion testing and maintain ±1°C stability makes it the preferred choice for high-precision industries such as aerospace, automotive, and medical devices.
