Popis:	With the publication of EN ISO 6892-1:2009 [1], the harmonisation of tensile testing at room temperature in Europe was achieved by combining EN 10002-1:2001 [2] with ISO 6892:1998 [3]. Essential changes are the introduction of the strain rate and the strain rate control as the significant testing rate or control mode, respectively, referred to as “Method A”. By using this method in the correct way it is guaranteed that in the moment of determination of properties comparable resulting strain rates at the test piece in smaller ranges of specified strain rates are adopted — also if different stiffnesses of the testing equipment are present. This leads especially for strain rate sensitive materials to better comparable results. In this paper it is documented the need for the implementation of method A, methods for the realisation — also by the use of older testing systems — and an example of the comparability of results of the methods for a strain-rate-sensitive-steel.
