摘要： A method for measuring a degree of cross-linking of a component of elastomeric material obtained as a result of a hot-forming process, includes a preliminary calibration step in which a plurality of samples are provided, made of the same material as the component. The samples 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 having an electrical circuit, in which a voltage generator is arranged in series with metal contacts configured to selectively receive a sample, and an ammeter, positioning a sample between said metal contacts, providing a predetermined voltage value, and detecting the corresponding current value by means of said ammeter. The aforesaid steps are repeated for each sample so as to obtain a calibration map that associates a given degree of cross-linking of the material constituting said component with each determined value of electrical conductivity.
