Abstract
A method for non-destructively testing the heating of a determined zone of a part made of a polymer material, comprising: a) taking at least one colorimetric measurement on said determined zone to be tested and obtaining the values a, band Lof the parameters a, b and L of the CIELAB colorimetric space; b) taking at least one colorimetric measurement on said reference zone of the part and obtaining the values a, band Lof the parameters a, b and L of the CIELAB colorimetric space; c) calculating the colour difference ΔEbetween the colorimetric measurements obtained in steps a) and b); and d) from the value ΔE, determining the time period during which said zone to be tested of the part has been subjected to a determined heating temperature, by using a reference database.
