Abstract: The invention relates to a non-destructive method for measuring the elasticity of templates of materials for lining automotive vehicle components, characterized in that it comprises the following steps: applying a tensile pre-load with a predetermined value P1 in a longitudinal direction to a template section (41); applying a tensile load with a predetermined value P2 in a longitudinal direction to said section (41) and measuring the longitudinal deformation produced; removing the load applied to said section (41) and measuring the residual longitudinal deformation produced. The invention also comprises an apparatus (11) for carrying out the method which comprises two fixing elements (15, 17) for fixing the section (41), one of which elements is a fixed element (15) and the other is a moving element (17), a device for applying a tensile load to the moving element (17) connected to a dynamometer (29), and a rule (31) for measuring the longitudinal deformation of said section (41).

Abstract: The invention relates to a method for determining the adaptability of lining materials for automotive vehicle components, which materials are joined thereto by means of an adhesive, comprising the following steps: obtaining samples (13) of the material with several diameters Dmi; providing disc-shaped jigs (11) with a central recessed area (15) and an intermediate area (17), the diameter Dz of the latter being greater than the diameters Dmi, and such diameters Dmi being smaller than the diameter Dc of the central recessed area (15); applying said adhesive to the samples (13) and the jigs (1) and placing the samples (13) on the jigs (11) inside the intermediate area (17); detecting the presence or absence of creases in the samples (13); determining the adaptability according to the difference of the diameter Dmi of the samples (13) that do not have creases with respect to the diameter Dc of the central recessed area (15).
