DIN SPEC 4864
The indentation method according to DIN SPEC 4864 offers decisive improvements in the field of materials testing, so that a large number of steel, aluminium, nickel, titanium and copper materials can now be tested accurately and more extensively 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 Bundes anstalt (PTB, Braunschweig), the Materialprüfungsamt NRW in Dortmund (MPA NRW) and several industrial partners.
A major benefit of the indentation method according to DIN SPEC 4864 is the fast and cost-effective determination of mechanical properties. In this context, the indentation method can be compared with various hardness testing methods and the tensile test.
The DIN SPEC 4864 method is based on highly accurate 3D measurements of test indentations and finite element simulations. The procedure, which takes only seconds, is fully automatic and does not require any specialist knowledge on the part of the user.
If DIN SPEC 4864 is applied internally, a pronounced material, machine and personnel expenditure can be avoided in comparison to the performance of tensile tests. Compared to external testing by a test laboratory, long waiting times can be avoided. The indentation method can also be applied to small and thin components up to layers.
The aim of DIN SPEC 4864 was to provide the user with a simple, safe and precise alternative to the tensile test. In many cases, the non-destructive determination of the characteristic values offers an alternative to the tensile test with the corresponding advantages. Compared to conventional hardness testing, DIN SPEC 4864 allows a higher informative value and precision to be achieved.
