Defines procedures for determining the coefficient of thermal expansion of hardened structural bonding agents. The first procedure gives a continuous measurement of linear thermal expansion by means if thermochemical analysis techniques. May also be used for surface protection systems.

This European Standard specifies methods for the determination of the coefficient of thermal expansion of hardened structural bonding agents. The first method provides a continuous measurement of linear thermal expansion using thermomechanical analysis techniques. This method may also be used for surface protection systems. The alternative method uses prisms of 40 mm × 40 mm × 160 mm. This method may also be used for repair mortar. Both methods are suitable for bonding agents formulated with fillers of up to 4 mm.
