ASTM E1806 : 09

Standard Practice for Sampling Steel and Iron for Determination of Chemical Composition

Standard Details

1.1 This practice covers the sampling of all grades of steel, both cast and wrought, and all types (grades) of cast irons and blast furnace iron for chemical and spectrochemical determination of composition. This practice is similar to ISO 14284.
