ASTM B117
Full Name
ASTM B117 – Standard Practice for Operating Salt Spray (Fog) Apparatus
Scope
ASTM B117 is a standard practice that outlines the procedure for operating a salt spray (fog) apparatus. This apparatus is used to simulate the corrosive effects of salt-laden environments, such as coastal regions or industrial areas. By exposing materials to a continuous mist of salt solution, ASTM B117 provides a controlled environment for evaluating the corrosion resistance of various products.
Key components and parameters of a salt spray apparatus include:
- Salt solution: a specific concentration of sodium chloride (salt) is used to create the corrosive environment.
- Temperature: the temperature of the salt solution is maintained at a constant level, typically 35°C (95°F).
- Humidity: the relative humidity within the apparatus is controlled to ensure optimal corrosion conditions.
- Spray rate: the rate at which the salt solution is sprayed onto the test specimens is specified to simulate natural conditions.
- Test duration: the length of the exposure period depends on the specific requirements of the application and the desired level of corrosion resistance.
