Cyclic Corrosion Test Chamber

Name: Cyclic Corrosion Test Chamber
Brand: Xi'an LIB Environmental Simulation Industry

Simulate Alternating Corrosion Environments, Not Just Continuous Salt Spray

LIB industry cyclic corrosion test chamber is designed to reproduce programmed corrosion environments by alternating salt spray, humidity, temperature, drying, and other environmental conditions. Unlike conventional salt spray testing, which exposes specimens to continuous salt fog, cyclic corrosion testing evaluates how materials and components respond to changing environmental conditions，seamlessly automate multi-stage testing—including neutral salt spray, drying, and high-humidity cycles.

The chamber supports NSS, AASS, CASS, Prohesion, and cyclic corrosion testing, with programmable test profiles for automotive components, coatings, metal products, electronics, new energy components, and materials research.

Models: SC-010, SC-016, SC-020

Standards: ASTM G85, ASTM B117, ISO 9227, ISO 11997-1, ISO 11997-2, IEC 60068-2-52, SAE J2334, GM 9540P, GM 4298P, GM 4476P, WSK-M2G299 and others.

What Does a Cyclic Corrosion Test Cycle Look Like?

Different standards define different corrosion cycles. The following example shows how an automotive cyclic corrosion procedure can alternate environmental conditions instead of maintaining continuous salt spray.

SAE J2334 Automotive Cyclic Corrosion Cycle

24-Hour Cycle

① Humid Stage

50°C · 100% RH · 6 h

② Salt Application

15 min · Salt Solution

③ Dry Stage

60°C · 50% RH · 17 h 45 min

Repeat the Cycle

24 h → 24 h → 24 h → ...

This cycle illustrates the basic principle of cyclic corrosion testing:

High Humidity → Salt Application → Drying → Repeat

The exact exposure procedure should always be configured according to the applicable standard, revision, and test requirement.

Key Features for Stable Cyclic Corrosion Testing

Programmable Test Cycles

The control system manages temperature, humidity, salt spray and other programmed stages, allowing the chamber to automatically switch between different environmental conditions during a test cycle.

Corrosion-Resistant FRP Workroom

The reinforced glass fiber reinforced plastic workroom is molded as an integrated structure to provide corrosion resistance and reduce the risk of water leakage.

Controlled Salt Fog Distribution

The atomizer tower and spray nozzles generate salt fog and distribute it throughout the workroom. Salt fog deposition can be monitored using the standard collection system.

Integrated Temperature and Humidity Control

Heating, refrigeration and humidification systems work together to establish the temperature and humidity conditions required for different stages of cyclic corrosion testing.

Adjustable Specimen Placement

The standard round-bar sample holder allows specimens to be positioned at different angles. Customized specimen fixtures are also available for special test requirements.

Automated Operation and Safety Protection

The programmable controller enables automated test operation, while multiple protection functions help safeguard the equipment during long-duration testing.
