G85 Standard Practice for Modified Salt Spray (Fog) Testing
This practice is applicable to ferrous and nonferrous metals; also organic and inorganic coatings. The variations described herein are useful when a different or more corrosive environment than the salt fog described in Practice B 117 is desired.
1.1 This practice covers and sets forth conditions for five modifications in salt spray (fog) testing for specification purposes. These are in chronological order of their development:
1.1.1 Annex A1, acetic acid-salt spray test, continuous.
1.1.2 Annex A2, cyclic acidified salt spray test.
1.1.3 Annex A3, seawater acidified test, cyclic (SWAAT).
1.1.4 Annex A4, SO2 salt spray test, cyclic.
1.1.5 Annex A5, dilute electrolyte cyclic fog dry test.
1.2 This practice does not prescribe the type of modification, test specimen or exposure periods to be used for a specific product, nor the interpretation to be given to the results.
