1. A method for inspecting a quality and/or condition of an elongated composite member, which is a load bearing member of a hoisting rope of a hoisting apparatus or a precursor of the load bearing member, the method comprising:
providing the elongated composite member;
changing a temperature of said elongated composite member by cooling said elongated composite member via a flank thereof, the cooling including inducing heat transfer from the elongated composite member to a fluid that is in relative motion with respect to the elongated composite member such that the elongated composite member is in a cooled state after said changing of the temperature is complete;
scanning said elongated composite member from a lateral side thereof with a thermal imaging device after said changing of the temperature is complete and the elongated composite member is in the cooled state; and
creating thermographic images of said elongated composite member based on the scanning,
wherein the method is performed during a manufacturing of the hoisting rope including said elongated composite member.
