ASTM E112-12 PDF

These test methods may also be applied to nonmetallic materials with structures having appearances similar to those of the metallic structures shown in the comparison charts. These test methods apply chiefly to single phase grain structures but they can be applied to determine the average size of a particular type of grain structure in a multiphase or multiconstituent specimen. These distributions are approximately log normal. These test methods do not cover methods to characterize the nature of these distributions.

These distributions are approximately log normal. These test methods do not cover methods to characterize the nature of these distributions.

Characterization of grain size in specimens with duplex grain size distributions is described in Test Methods E Measurement of individual, very coarse grains in a fine grained matrix is described in Test Methods E Determination of spatial grain size, that is, measurement of the size of the three-dimensional grains in the specimen volume, is beyond the scope of these test methods.

Utilization of semi-automatic digitizing tablets or automatic image analyzers to measure grain size is described in Test Methods E Equivalent inch-pound values, when listed, are in parentheses and may be approximate.

Kagazahn For determining the mean grain size, and the distribution of grain intercept lengths or grain areas, for polycrystalline metals and nonmetallic materials with equiaxed or deformed grain shapes, with uniform or duplex grain size distributions, and for single phase or multiphase grain structures, use the companion standard ASTM E For higher degrees of accuracy in determining average grain size, the intercept or planimetric procedures may be used. This will give you two copies of the standard. Equivalent inch-pound values, when listed, are in parentheses and may be approximate.
