Abstract

With base in the precepts and technical procedures of ISO 6508-1 standard and ISO/FDIS 14577-1 standard draft, Rockwell hardness testing and instrumented indentation testing (IIT) were carried out using a universal testing machine, through adaptation of a system developed for these ends. The results pointed out a good relation between the two hardness tests, taking into account that IIT can provide other materials parameters besides being the simplest method, not requiring any preliminary force or operator influence. Nevertheless, it was observed the necessity of the improvement of the used system, regarding the monitoring of zero-point.
