1.1 These test methods describe simple manual procedures for estimating the size of the largest grain observed on a metallographically prepared plane section. 1.2 These test methods shall only be valid for microstructures containing outlier course grains, where their population is too sparse for grain size determination by Test Methods E112. 1.3 This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. |
