Standards Supported – ASTM B117 & ISO 9227

ASTM B117 – Salt Spray (Fog) Test

ASTM B117 defines the apparatus and operating conditions for salt spray corrosion testing.
The Salt Spray Test Chamber SST-216B supports standard requirements including controlled temperature,
fog generation and fog collection monitoring for repeatable test results.

ISO 9227 – Corrosion Tests in Artificial Atmospheres

ISO 9227 specifies corrosion tests in artificial atmospheres and covers NSS/AASS/CASS methods depending on test requirement.
This chamber is manufactured for laboratory use and can be configured as per customer test method.

Salt spray test (ASTM B117) – overview

How Salt Spray Test Chamber SST-216B Works

In the Salt Spray Test Chamber SST-216B, a salt solution is atomized through specialized nozzles to form
a fine fog inside the exposure chamber. Test specimens are mounted on rods/holders at defined angles so that fog settles
uniformly. The chamber maintains a controlled environment, typically 35 ± 2°C, to produce repeatable
corrosion exposure as per test standard.

• Salt solution is prepared and maintained in the reservoir tank
• Oil-free compressed air is regulated to create stable fog
• Fog falls on specimens uniformly inside the chamber
• Fog collection and pH are checked to confirm standard conditions

Recommended Test Settings (Typical ASTM B117 Guidance)

Temperature Control

The exposure zone is maintained at 35 ± 2°C. Temperature control ensures repeatable corrosion rate.

pH of Collected Solution

The pH of collected solution is maintained in the range 6.5 to 7.2 at 35°C (typical NSS requirement).
A pH meter is used to verify this during testing.

Air Supply & Pressure

Air must be clean, oil-free and dust-free. Typical pressure is maintained at 1.0 kg/cm² ± 0.2
to achieve stable fog generation.

Fog Collection Rate

Fog quantity is typically maintained so that 1.0 to 2.0 mL/hour is collected per 80 cm²
(4-inch funnel area) based on an average run of at least 16 hours.

Step-by-Step: Running a Salt Spray Test (Quick Guide)

1. Prepare saline solution (as per test method) and fill reservoir tank.
2. Mount specimens on hanging rods with proper spacing (avoid touching).
3. Set chamber temperature and allow system to stabilize.
4. Start fogging and confirm uniform spray and fog collection.
5. Check pH and fog collection rate periodically during the test.
6. Complete test duration and record results (visual inspection / rating).

Typical Applications – Salt Spray Test Chamber SST-216B

• Electroplating quality verification (zinc, nickel, chrome, etc.)
• Powder coating / paint coating performance evaluation
• Automotive parts, fasteners, hardware and fabricated components
• Surface treatment labs, job coaters and inspection labs
• R&D and QA/QC laboratories for corrosion testing

The Salt Spray Test Chamber SST-216B is widely selected by labs that need a stable,
medium-capacity chamber with ASTM B117 features and easy maintenance.
