备注:
范围:1.1 These test methods cover the measurement of average grain size and include the comparison procedure, the planimetric (or Jeffries)  procedure, and the intercept procedures. 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. 1.2 These test methods are used to determine the average grain size of specimens with a unimodal distribution of grain areas, diameters,  or intercept lengths. 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 E1181.

国内尚无类似标准,看下参考下!
