asgm It is the responsibility of the user of this standard to axtm appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. 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.
The moment new editions of the standards you monitor are released, changes are made, or appendixes are published, you will be alerted by email.
You may delete a document from your Alert Profile at any time. 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.

Historical Version s – view previous versions of standard Translated Version s: Characterization of grain size in specimens with duplex grain size distributions is described in Test Methods E The intercept procedure is particularly useful for structures consisting of elongated e11-212 see Section Active view current version of standard.
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.
