Abstract

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.

Extended English version of the plenary lecture of the materials testing conference “Werkstoffprüfung 2010” [4]

Dipl.-Ing. Johannes Aegerter, born in 1964, studied at the University of Appied Science in Osnabrück material engineering. Since 1989 he is working in the Research and Development of VAW, now Hydro Aluminium Rolled Products in Bonn, presently as Project Leader in the Research Department Rolling, Products.

Prof. Dr.-Ing. Holger Frenz, born in 1961, received his Diploma at the Technical University of Braunschweig. Between 1987 and 1997 he was head of laboratory at the Federal Institute for Materials Research and Testing (BAM) in Berlin. Science 1997 he is professor for Materials Testing at the University for Applied Sciences Gelsenkirchen in the city of Recklinghausen. The main focus of his work is quality management in testing laboratories and related accreditation processes. At the moment he is chair of the Technical Committee “Materials Technology” of the German Accreditation Body (DAkkS).

Dipl.-Ing. Hans-Joachim Kühn, born 1950, studied Mechanical Engineering at the Technical University of Applied Science in Berlin. He is with BAM since 1976, currently working in Division 5.2 as an engineer focusing on TMF testing. He is an active member of the DIN working group “Tensile and Ductility Testing of Metals” as well as of an international working group for revision of ISO 6892.

Dipl.-Ing. Christian Weißmüller, born in 1972, received his Diploma at the University for Applied Sciences in Gelsenkirchen. Since 2004 he is employed as CEO of the Institut für Eignungsprüfungen GmbH in Marl. He works voluntary in the committee NA 062-01-44 AA “Impact testing on metals” of the DIN. Since 2005 he conducts seminars to the topic of measurement uncertainty evaluation and advises laboratories on the introduction of quality assurance measures.
