    en.wikipedia.org/wiki/Salt_spray_test

    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.

  9. Unified numbering system - Wikipedia

    en.wikipedia.org/wiki/Unified_numbering_system

    Many material or standard specifications include a number of different UNS numbers that may be used within that specification. For example: UNS S30400 (SAE 304, Cr/Ni 18/10, Euronorm 1.4301 stainless steel) could be used to make stainless steel bars ( ASTM A276 ) or stainless steel plates for pressure vessels ( ASTM A240 ) or pipes ( ASTM A312 ).
