What is ASTM B117?
ASTM B117 is one of the world’s most widely adopted corrosion testing standards for evaluating the corrosion resistance of coatings, surface treatments, metals, electroplated parts, paints, automotive components, electronic enclosures, and industrial materials.
The standard defines a controlled salt fog environment used to accelerate corrosion processes and evaluate long-term durability performance under highly corrosive conditions. ASTM B117 testing is commonly specified by automotive manufacturers, military suppliers, aerospace contractors, electronics brands, and industrial OEMs worldwide.
At TestEQ, we provide high-reliability ASTM B117 salt spray corrosion chambers engineered for repeatable testing performance, stable fog distribution, precise temperature control, and long-term industrial operation.

Main ASTM B117 Test Requirements
ASTM B117 specifies standardized conditions for neutral salt spray exposure testing.
Key Test Parameters
| Item | Requirement |
|---|---|
| Salt Solution | 5% NaCl Solution |
| Chamber Temperature | 35°C |
| pH Range | 6.5 – 7.2 |
| Fog Collection Rate | 1–2 mL/hour |
| Spray Type | Continuous Salt Fog |
| Test Duration | Customized by Product Specification |
The test exposes samples to continuous salt fog conditions to evaluate coating degradation, rust formation, blistering, oxidation, and corrosion propagation.
