| description | A method for measuring the degree of cross-linking of a component (C) of elastomeric material obtained as a result of a hot-forming process, comprises a preliminary calibration step in which a plurality of samples (8) are provided, made of the same material as the component (C). The samples (8) have different degrees of cross-linking following respective hot-forming processes conducted for different periods of time. The preliminary calibration step includes: providing a measuring device (I) comprising an electrical circuit, in which a voltage generator (5) is arranged in series with metal contacts (7) configured to selectively receive a sample (8), and an ammeter (6); positioning a sample between said metal contacts (7), providing a predetermined voltage value, and detecting the corresponding current value by means of said ammeter (6). The aforesaid steps are repeated for each sample (8), so as to obtain a calibration map (M) that associates a given degree of cross-linking of the material constituting said co |
