This document describes the procedure for determining the creep (total creep, basic creep and drying creep) of hardened concrete test specimens subjected to a sustained longitudinal compressive load.

The test is suitable for specimens having a declared value of D of the coarsest fraction of aggregates actually used in the concrete (D_max) not greater than 32 mm.
