Training and certification of the specialists on heat monitoring of all levels according to the requirements of EN ISO 9712:2012 standard stipulate work with examination samples for performance of the heat monitoring procedures and getting skills for decoding of received thermograms. The peculiarities of preparation of the examination samples that can be used for certification of the specialists of all levels  as well as for holding the practical classes during training were considered. Heat sources allowing modelling different conditions of control objects operation were examined. A specific type of the objects, which at set operation conditions can not be adequately operated using industrial thermal imagers, was determined. It is caused by small temperature difference over defect, which is significantly less than the temperature error of measurement heat monitoring equipment. 3 Ref., 9 Fig.
