A fastening arrangement fastens a sample holder to a force measuring device. The fastening arrangement has a sample holder, a counterpart holder on the side of the force measuring device. The counterpart holder has a sample holder receptable. The sample holder has a planar abutment surface and the sample holder receptacle has a flat counterpart abutment surface. The sample holder has a positioning element and a fixing element. The sample holder receptacle has a counterpart positioning element and a counterpart fixing element. The positioning element and the counterpart positioning element uniquely define a relative position between the sample holder and the counterpart holder together with the abutment surface and the counterpart abutment surface. The fixing element and the counterpart fixing element hold the sample holder and the counterpart holder against one another and force the abutment surface and the counterpart abutment surface against one another.

Fastening arrangement for fastening a sample holder to a force measurement device, sample holder and counterpart holder for a fastening arrangement of said type, and force measurement device having a fastening arrangement of said type

The invention relates to a fastening assembly () for fastening a test device holder () to a force measuring apparatus (), having a test device holder () and a slide part () which can be or is arranged on a force measurement tower () of the force measuring apparatus () in such a way that the slide part can move in the vertical direction of the force measurement tower (). The test device holder () has at least one position defining element (), and the slide part () has at least one counter position defining element (). The position defining element () and the counter position defining element () are designed to fix the position of the test device holder () relative to the slide part () in at least one direction, selected from the vertical direction of the force measurement tower () and a direction perpendicular to the vertical direction, and at the same time to allow rotation of the test device holder () relative to the slide part () about an axis of rotation (D) defined by the position defining element () and/or the counter position defining element (). The test device holder () has a first angle adjustment device () and the slide part () has a second angle adjustment device (), which are designed to adjust and preferably to fix the angle of the test device holder () relative to the slide part () about the axis of rotation (D). The test device holder () has at least one fixing element () and the slide part () has at least one counter fixing element (). The fixing element () and the counter fixing element () are designed to fix the test device holder () on the slide part ().

Fastening assembly for fastening a test device holder to a force-measuring apparatus, force-measuring apparatus having a fastening assembly of this type, test device holder, and slide part for a force-measuring apparatus

The invention relates to a force measuring arrangement () in particular for applying a test parameter to a specimen and/or for measuring a resistance force applied by the specimen, having at least one force absorption element (), a first fastening device and a force transmission element (), wherein the force absorption element () can be fastened to a force measuring device in a movable manner by means of the first fastening device, wherein the force absorption element () is designed to measure a relative force acting between two force absorption regions, namely a first force absorption region and a second force absorption region (), wherein the first fastening device is able to be connected to the force absorption element () in a force-transmitting manner via the first force absorption region, wherein the second force absorption region () is able to be connected to the force transmission element () in a force-transmitting manner by means of a second fastening device, wherein the force transmission element () is designed to apply a test parameter to a specimen. The force measuring arrangement is notable in that the second fastening device has a magnet () that is designed to retain the force transmission element () at least in a state connected to the second force absorption region () in a force-transmitting manner.
