This standard is not included in any packages. 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.

The precision of the method is a function of the number of grains counted. Because they show a distribution of grain dimensions, ranging from very small to very large, depending on the relationship of the planar section and the r112-12 array of grains, the charts are not applicable to measurement of individual grains.

The test methods may also be used for any structures having appearances similar to those aztm the metallic structures shown in the comparison charts. Heyn Linear Intercept Procedure.
