The Salt Spray Chamber (also known as a Salt Fog Test Chamber or Corrosion Test Chamber) by Pacorr Testing Instruments is a precision-engineered system designed to evaluate the corrosion resistance of metals, alloys, electroplated components, painted surfaces, and coated materials under accelerated environmental conditions.
Built in accordance with ASTM B117, ISO 9227, JIS Z 2371, and DIN 50021, Pacorr’s chamber simulates a highly corrosive saline atmosphere to predict long-term product durability within days or weeks instead of years. It is widely used across automotive, aerospace, marine, infrastructure, hardware, and surface-coating industries for quality assurance, R&D validation, and regulatory compliance.

What is a Salt Spray Chamber?
A Salt Spray Chamber is an environmental testing instrument used to perform accelerated corrosion testing. It creates a controlled salt-laden fog environment that mimics coastal, marine, or industrial atmospheric conditions.
This test helps manufacturers determine:
- Coating life expectancy
- Rust resistance performance
- Surface treatment effectiveness
- Material suitability for harsh environments
- Compliance with international standards
By exposing samples to continuous salt fog at controlled temperature and humidity, corrosion behavior is evaluated in a reproducible and standardized manner.
Working Principle of Salt Spray Chamber
Pacorr’s chamber operates on the principle of continuous atomization of a saline solution inside a thermally controlled chamber.
Step 1: Preparation of Salt Solution
A 5% sodium chloride (NaCl) solution is prepared using distilled water. The pH is maintained between 6.5 and 7.2 for Neutral Salt Spray (NSS) testing.
Step 2: Air Saturation
Filtered compressed air passes through a heated air saturator maintained at 45°C–47°C. This ensures proper humidification and prevents dry spray deposition.
Step 3: Fog Generation
The saturated air mixes with the salt solution through a corrosion-resistant atomizing nozzle, producing a fine, dense salt fog uniformly distributed throughout the chamber.
Step 4: Controlled Test Environment
The chamber temperature is maintained at 35°C ±2°C using a microprocessor-based PID controller, ensuring consistent and repeatable results.
Step 5: Continuous Exposure
Specimens are mounted at a 15°–30° inclination to allow proper drainage and uniform exposure. Testing duration may vary from 24 hours to over 1000 hours depending on industry requirements.
Step 6: Evaluation
After completion, samples are inspected for:
- Red rust formation
- White corrosion (zinc oxidation)
- Blistering and peeling
- Pitting depth
- Coating delamination
