Looking specifically at steel, ASTM standards are typically used to differentiate the steel grade and chemical composition of the material, as well as testing and finishing services. An example of ASTM designations for finishing services would be hot-dip galvanizing steel , which has three ASTM codes that govern the process and guidelines: A123 . A capsule containing Charpy V-notch (CVN) and mini-tensile specimens was irradiated at ~30°C (~ 85°F) in the cavity of a commercial nuclear power plant to a fluence of 1 x 10 16 neutrons/cm 2 (>1 MeV). The capsule included six CVN impact specimens of archival High Flux Isotope Reactor A212 grade B ferritic steel and five CVN impact specimens of a well .This specification establishes the procedure for Charpy V-notch testing of structural steel and contains two frequencies of testing.
