History of ASTM B117
Continuous salt spray testing first became widely adopted as a corrosion test in 1939 when the American Society of Testing and Materials (ASTM) first published their salt spray test standard, known under its reference number: ASTM B117. In subsequent years, the use of ASTM B117 spread internationally and its provisions have frequently been re-written into national standards such as the UK's BSI, Germany's DIN etc., underpinning the widespread use of the standard today. The terms salt spray, salt fog and salt mist are all in widespread use for this type of testing and are generally interchangeable terms, as is the term cabinet or chamber, which is used to describe the equipment in which the test is conducted.
