ASTM B117 Testing — Laboratories & Overview
ASTM B117 defines the apparatus and operating conditions for salt spray (fog) exposure, a comparative corrosion test widely referenced by coating and finish specifications.
When is it used?
- Coating and plating qualification
- Finish comparison between suppliers
- Specification conformance for hardware and assemblies
Sample considerations
- Exposure duration and evaluation criteria come from the product specification, not from B117 itself.
- Panel orientation, masking and edge treatment should be defined.
