    摘要： A method of performing a shear test using a test tool comprises providing a surface with an aperture (92) formed in the surface, indexing a wire (93) through the aperture (92) to protrude past the surface, contacting the portion of a wire (93) protruding past the surface with the test tool (94) to shear the portion of the wire (93) off the remainder of the wire, measuring the shear load applied to the test tool (94) by the portion of the wire while the portion of the wire is being sheared off by the test tool (94), and comparing the measured shear force with a shear force measured by a different test tool which was brought into contact with another portion of the wire (93).

    摘要： A method and a device for determination of abrasive forces, wherein at least two distinguishable layers, which are removable by scraping, are applied on a substrate one on top of the other and so as to cover one another. In addition, each layer is associated with a predetermined abrasive force required to penetrate and remove the layer by scraping, and this strength is smaller the closer to the surface that the layer is positioned. When the layers are subjected to abrasive forces, parts of the applied layers are scraped off, starting from the outermost layer and further downwards into the underlying layers, and thus one of the layers is laid bare (exposed) at each point, which indicates the abrasive force at that point. The thus exposed surface of each layer may then be identified. The method and the device are particularly suitable in car-crash testing in order to assess the abrasive forces arising from e.g. airbags.

    摘要： A method for calibrating an apparatus for calibrating a hardness tester, the method comprising the steps of: setting a plurality of calibration points between a rated force point at which a rated force of a force measuring member is applied and a zero point at which no-load is applied, for measuring outputs(mV/V) from the force measuring member according to test forces(N) applied to the force measuring member; and calculating a relation between the test forces(N) and the outputs(mV/V) as an approximation based on the test forces(N) and the outputs(mV/V) according to the test forces(N) at the calibration points. An apparatus for evaluating a dynamic characteristic of a specimen, which installed in a hardness tester, the apparatus comprising: a force measuring member (12); a force transmitting portion (14) which is movable up and down; a distance measuring member (13) incorporated in the force transmitting portion (14) to be contacted with the force measuring member (12) from above; and an indenter.

    摘要： A meat probe for determining the tenderness of meat. A piston (12) slidably mounted in a body (13) has a probe member (11) attached thereto. Force is applied to the piston by means of a spring (16) and a second piston (15) advanced by means of a trigger assembly (18). Scales associated with the first and second pistons measure the depth of penetration of the probe and the force required for penetration respectively. The measurements may be used alone or in conjunction in determining tenderness.
