DIN SPEC 4864
Fast and non-destructive alternative to the tensile test
The impression method according to DIN SPEC 4864 offers significant improvements in the field of material testing, so that a large number of steel, aluminum, nickel, titanium and copper materials can now be precisely and extensively tested for mechanical properties comparable to the tensile test. It was developed in cooperation with the Federal Institute for Materials Testing (BAM, Berlin), the Physikalisch-Technische Bundesanstalt (PTB, Braunschweig), the Materialprüfungsamt NRW in Dortmund (MPA NRW) and several industry partners.
An important benefit of the indentation process according to DIN SPEC 4864 lies in the fast and cost-effective determination of mechanical properties. In this context, the indentation method can be compared with various hardness test methods and the tensile test.
The DIN SPEC 4864 method is based on highly accurate 3D measurements of test impressions and finite element simulations. The process, which takes only seconds, is fully automated without the user having to have the necessary specialist knowledge.
When the DIN SPEC 4864 is used internally, significant material, machine and personnel costs can be avoided in comparison with the execution of tensile tests. Compared to the external implementation by a test laboratory long waiting periods can be omitted. The impression method can also be applied to small and thin components up to layers. The aim of the DIN SPEC 4864 was on the one hand to provide the user with a simple, safe and precise alternative to the tensile test.
The non-destructive determination of the characteristic values offers in many cases an alternative to the tensile test with the corresponding advantages. Compared to conventional hardness testing, the DIN SPEC 4864 offers greater informative value and precision.
