Salt Mist Testing Equipment For Fastener Testing

The salt mist testing equipment offers internal volume choices from 110L to 1,800L, ensuring batch testing consistency, while fog uniformity is kept <±2% deviation to prevent "uneven failure judgment." Cycle modes (NSS, AASS, CASS) simulate years of outdoor aging in mere weeks, supporting duration up to 1,500 hours. When fastener safety equals structural safety-controlled salt mist testing becomes non-negotiable. Compliant with ASTM B117 and ISO 9227 standards, this equipment combines precision, efficiency, and durability, making it ideal for automotive, aerospace, and industrial fastener testing. Maximize your product reliability and accelerate testing-contact LIB industry today for a tailored solution.

Fasteners are key components in automotive, aerospace, electronics, and industrial machinery. Their failure due to corrosion can compromise mechanical integrity and safety. Salt mist testing identifies potential issues such as:

 Surface corrosion and coating degradation – Zinc plating, nickel coating, or other surface treatments can fail under saline exposure.

 Material deterioration – Stainless steel or alloy steel fasteners may develop pitting, crevice corrosion, or structural weakness.

 Thread and joint integrity loss – Ensures that bolts and screws maintain torque and clamping force under corrosive conditions.

 Compliance verification – Helps meet ASTM, ISO, or JIS corrosion resistance standards for fasteners.

By testing fasteners in a controlled salt mist environment, manufacturers can optimize coatings, improve material selection, and prevent premature failures in critical applications.

 

 

Key Advantages of Salt Mist Testing Equipment for Fastener Testing

 

 

Precise Salt Fog Uniformity
Engineered with micro-orifice atomizing nozzles and equal-pressure pipelines to ensure consistent corrosion rates across the workspace-critical for batch comparison of 100–500 fasteners.

Triple Salt Spray Modes in One System (NSS / AASS / CASS)

• NSS: 35 ± 2 °C │ 5% NaCl
• AASS: 50 ± 2°C │ Acidified
• CASS: 50 ± 2°C │ Copper-accelerated

Compatible with stainless steel, zinc-plated, Cr3+, Geomet, and Dacromet-coated fasteners.

One-Piece Fiberglass-Reinforced Plastic (FRP) Construction
The salt mist testing equipment body is made from corrosion-proof, single-mold FRP material-no internal seams, no metal exposure, superior thermal stability, and extended structural lifespan even during continuous acidified testing modes.

Long-Duration Testing 24–1500 Hours
Industrial-grade dehumidifying module and auto water refill allow 7–60 days of uninterrupted operation.

Low Leakage Safety Design
Dual-seal structure with anti-backflow air channel protects lab equipment and operators in long-term use.

Large-Capacity Space with Heavy Load
Available in 110L / 780L / 1800L and more standard volumes for heavy bolts, anchors, or bulk sample trays.

Full Parameter Traceability (Temperature, pH, Deposition 1–2 mL/80cm²·h)
Downloadable data supports PPAP documentation, aerospace quality records, and OEM audits.
