The ASTM B117 standard is an established and internationally recognized test method used to measure the corrosion resistance of coated and uncoated materials.

Developed by the American Society for Testing and Materials (ASTM), the B117 standard defines the process of salt spray or salt spray testing, an accelerated corrosion test that simulates a saline environment. The goal is to predict the performance of a material or coating in a corrosive environment.

Anti-corrosion testing according to industry standard ASTM B117

The ASTM B117 test, also known as the salt spray test, is a widely recognized method for evaluating the corrosion resistance of coated and uncoated metal materials. In this controlled laboratory test, specimens are exposed to a continuous salt spray environment, simulating real conditions that can lead to corrosion. The main objective is to determine the material’s ability to resist corrosion and evaluate the effectiveness of protective coatings applied to the surface.


  • Metallic coatings (e.g., zinc, nickel, chromium)
  • Non-metallic coatings (e.g., paints, varnishes, conversion coatings)
  • Galvanized and anodized parts
  • Stainless steel
  • Aluminum and aluminum alloys
  • Other corrosion-sensitive metals
