Quantitative microstructure characterization is currently required in R&D as well as in routine quality control of materials and products. Every step: preparation of the laboratory and specimens, measurements and interpretation of the results etc. can be a source of serious errors. Application of the ASTM guidelines can minimize these problems and improve international circulation of the results. The paper characterizes selected ASTM standards devoted to laboratory practice and analyses the complexity of microstructural materials characterization.
