ASTM B117 Salt Spray Chamber for Fasteners and Electroplating

Name: ASTM B117 Salt Spray Chamber for Fasteners and Electroplating
Brand: Xi'an LIB Environmental Simulation Industry

Corrosion resistance is critical for fasteners, electroplated parts, and protective coatings. The ASTM B117 salt spray chamber from LIB industry simulates accelerated corrosive environments using a 5% NaCl solution at 35°C, producing a uniform salt fog for reliable testing.

With a temperature range of ambient +10°C to 60°C, ±0.5°C stability, and 0.7–1.2 bar spray pressure, it ensures accurate, repeatable evaluation of metal materials, plating layers, and coatings. This salt fog testing equipment helps manufacturers quickly detect coating defects, verify plating quality, and ensure long-term product durability in harsh environments.

Models: S-150 | S-250 | S-750 | S-010 | S-016 | S-020 and more customized models

Standards: ASTM B117 | ASTM G85 | ISO 9227 | SAE J2334 | ISO 4611 | ISO 7253 | IEC 60068-2-11 | BS 3900-F12

Why Fasteners and Electroplated Parts Require Salt Spray Testing

Fasteners such as bolts, screws, nuts, and washers are widely used in automotive, aerospace, construction, and electronic products. Many of these rely on electroplated coatings—zinc, nickel, or chromium—for corrosion protection. However, coating defects, poor adhesion, or insufficient thickness can lead to premature corrosion, affecting performance and durability.

ASTM B117 salt spray testing simulates harsh corrosive environments to detect weaknesses before products reach the market. It helps manufacturers improve plating processes, verify coating performance, and ensure consistent quality.

Typical applications include:

Fasteners and industrial hardware	Electroplated components	Zinc, nickel, and galvanized metal parts
Automotive and marine equipment	Industrial machinery parts	Electrical connectors

By identifying potential coating failures early, salt spray testing ensures that components remain reliable, durable, and ready for demanding real-world conditions.

Key Features of ASTM B117 Salt Spray Chamber for Fasteners and Electroplating

The ASTM B117 salt spray chamber from LIB industry delivers precise, reliable, and standards-compliant corrosion testing.

Corrosion-Resistant Construction

The chamber interior and exterior are made of one-piece molded fiberglass (FRP) and A3 steel, with an inverted-V transparent lid. This prevents condensation drip, minimizes salt fog leakage, and extends chamber life.

Uniform Salt Fog Distribution

Quartz nozzles and a dedicated salt spray tower maintain 83 kPa spray pressure and 1–2 mL/80 cm²·h deposition. A collector with a measuring cylinder ensures even distribution and full ASTM B117 compliance.

Precise Environmental Control

PT‑100 Class A sensors (0.001 °C accuracy) maintain stable temperatures. Supports NSS, AASS, and CASS testing with pH-adjusted solutions.

Intelligent Touchscreen Controller

Stores up to 120 programs (100 steps each), logs temperature, spray time, and pH, and exports results via USB/Ethernet. Automatic alarms reduce human error and downtime.

Automated Operation & Flexible Sample Handling

Automatic solution replenishment and nozzle cleaning enable continuous testing. Adjustable V-groove and rod holders accommodate various sample shapes and angles, ensuring accurate, validated results.
