ASTM B117-2019 is the standard experimental method for operating salt spray testing machines. It is designed to provide a controlled corrosion environment for evaluating the corrosion resistance performance of metal and coated metal specimens. This standard emphasizes the limited relevance and predictability of salt spray testing results to actual atmospheric exposure, particularly in long-term exposure situations. The repeatability of test results depends on the specimen type, evaluation criteria, and control of operating variables. The standard does not specify the specimen type or exposure period for a particular product, nor does it interpret test results, but provides specifications for equipment, procedures, and conditions. All values expressed in SI units shall be considered Standard values, and the accompanying SI unit values are provided for reference only. Users using this standard are responsible for ensuring that safety, health and environment practices comply with applicable regulatory restrictions.
