The salt spray test (or salt fog test) is a standardized and popular corrosion test method, used to check corrosion resistance of materials and surface coatings.Usually, the materials to be tested are metallic (although stone, ceramics, and polymers may also be tested) and finished with a surface coating which is intended to provide a degree of corrosion protection to the underlying metal.
The test methodology consisted of the ASTM B117 Standard Practice for Operating Salt Spray (Fog) Apparatus [52] which a corrosion expert, retained by the Competition Bureau, adapted in order to replicate the operational environment of an automobile. The test differed from the ASTM B117 insofar as the galvanized automotive steel panels were not ...

The oil and whiting method used an oil solvent for cleaning followed by the application of a whiting or chalk coating, which absorbed oil from the cracks revealing their locations. Soon a dye was added to the liquid. By the 1940s, the fluorescent or visible dye was added to the oil used to penetrate test objects.
ASTM International, formerly known as American Society for Testing and Materials, is a standards organization that develops and publishes voluntary consensus technical international standards for a wide range of materials, products, systems and services. Some 12,575 apply globally.
The Los Angeles abrasion test (LA abrasion) is the North American standard for testing toughness (resistance to abrasion and degradation [1]) of construction aggregate or gravel and its suitability for road construction. Test methodology and equipment is defined in the ASTM International publications ASTM C131 for particle sizes smaller than 37 ...
The test can be used for coatings or for base materials. The test method is defined by various standards, DIN EN ISO 6988, [2] DIN 50018, [3] ASTM G87, ISO 3231, ISO 22479 are the most common. The parts to be tested are placed in a test chamber with a capacity of 300L and exposed to warm, moist air in combination with a certain amount of sulfur ...
The Bresle method was launched in 1995 in the ISO 8502-6 and ISO 8502-9 standards. The test was developed to measure soluble salt concentration on steel surfaces prior to blasting cleaning and coating. Not only ISO, but also the US Navy, IMO, NAVSEA, and ASTM adopted this method as their standard. The method remains the primary and most ...
