This document specifies a standard method for the acquisition and analysis of data obtained using the test methods found in ISO 18437‑1 to ISO 18437‑5, ISO 6721‑4 to ISO 6721‑7 and ISO 6721‑12.
It is applicable to visco-elastic materials that are thermorheologically simple and that have been tested at equilibrium state for every temperature.
