ISO 1920-8:2009 is a standard that outlines a procedure for measuring the drying shrinkage of concrete samples prepared either in the field or in a laboratory setting. The standard provides a method for determining the length changes of the concrete specimens caused by the process of drying in air. It also specifies the procedures for preparing and curing the concrete samples before testing.

The standard sets out guidelines for the testing process, including the dimensions and shape of the concrete specimens, as well as the equipment and materials required. It details the preparation of the specimens, including the mixing and casting of the concrete, as well as the curing conditions. The standard also provides information on the measurement and calculation of the drying shrinkage of the concrete samples.
