  • Publication number: 20050039543
    Abstract: The invention relates to an apparatus and method for determining the shearing strength of a thermal insulation. The apparatus (1) comprises a mobile clamping element (2) and alongside the same at least one immobile clamping element (3), each provided with a cavity (2a, 3a) capable of receiving part of a strip-like test specimen (15) to be cut off a thermal insulation. The apparatus is adapted to apply a force F to the mobile clamping element for moving the mobile clamping element (2) relative to the immobile clamping element (3) for achieving the shearing of the presently measured strip (15) at a location (14) between the mobile clamping element (2) and the immobile clamping element (3). The apparatus is further provided with means (16) for measuring the force F for its magnitude. The method comprises cutting a thermal insulation for a strip-like test specimen (15), having certain dimensions in various directions, said strip being then placed in a measuring apparatus (1) for shearing strength.
