This document describes good practice for measurements of material microstructure in hot compression testpieces such as AC (axisymmetric) and PSC (plane strain). It is applicable to hot (isothermal) compression tests at medium to high rates of strain (10-4 to 102 s-1) at deformation temperatures below the solidus. Technical input to the document has been provided by a steering group containing academic researchers and representatives of industrial users and producers of a range of engineering materials. An experimental and modelling programme has been conducted during the preparation of the document to underpin the recommendations in the guide.
