ASTM B-201 vs. ASTM B-1117?



1998

We would be very grateful if someone could explain us something about ASTM B201-80 [affil. link to spec at Techstreet] norm and its eventual difference from ASTM ASTM B117 [affil. link to spec at Techstreet] norm. Thank you in advance.

Hello, Spina. B117 specifies how to run a neutral salt spray test and is not specific to any particular finish. B201 describes a number of testing methods for chromate coatings on zinc or cadmium, of which salt spray testing is one method.
