Working Principle – Salt Spray / Corrosion Test (ASTM B117 & ISO 9227)

Purpose of the Test

A corrosion test chamber (salt spray chamber) accelerates corrosion by exposing specimens to a controlled
salt fog environment. It is used to compare coatings and materials such as paint, powder coating,
electroplating, anodizing and conversion coatings for corrosion resistance under standardized conditions.

Standard Test Temperature

For Neutral Salt Spray (NSS) testing, the exposure zone is typically maintained at
35 ± 2 °C as defined in ASTM B117 / ISO 9227 for consistent, comparable results.

Salt Solution and pH

NSS testing typically uses a 5% NaCl solution prepared with deionized water.
As per ASTM B117, when atomized at around 35 °C, the collected solution pH should remain within
6.5 to 7.2.

Atomization and Quantity of Fog

Fog quantity is checked using collection funnels. A typical requirement is
1.0 to 2.0 mL per hour collected for each 80 cm² (4-inch funnel) of horizontal collecting area,
averaged over at least 16 hours of operation (ASTM B117 reference).

Air Supply and Fog Rate

The air supply should be oil-free and dust-free, regulated for stable fog generation.
Operating pressure is commonly around 1.0 kg/cm² ± 0.2 kg/cm² depending on nozzle and system design.
