Material`s thermal/mechanical performance characterizing method for purchasing e.g. car, involves comparing graph of tactile notation with reference or external reference according to thickness or bijective function for qualifying material
The method involves testing an indentation on a material to determine a value of stiffness which permits to assign a tactile notation evaluated from reference samples. A graph of tactile notation is compared with a reference derived from a sample chart or an external reference according to the thickness or a bijective function such as logarithm of values of the stiffness of the material, to qualify the material, where the external reference is constituted by a series of samples presenting increased hardness SENSOTACT(RTM: Not defined) that is ensured tactically by a panel operator. An independent claim is also included for a device for measuring tactile performance of a material, comprising an operating parameters recording unit.
