Abstract

A new technique is suggested in the paper to assess blackness level for heat resistant coatings. The technique is validated experimentally. Test results are compared with data obtained by means of other techniques and correlate with them satisfactorily. Special features of the technique are its portability, high precision and adequacy of obtained results. An algorithm of the experiment execution is described.

Keywords:
