The aim of presented studies was to develop a new geometry of the overflow part of standard ATD–C tester for derivative thermal analysis

in a way that it would allow to obtain samples for abrasion and mechanical properties tests in the same mould without the need of cutting

them from a block of material. The pattern of new ATD–P tester has parts reflecting implemented samples. Computer simulations

regarding initial verification of new tester were performed in NovaFlow software. Chromium cast iron melts were made for testing the

sampler in real conditions and TDA analysis for casting material were conducted. The sandmix was prepared on silica sand matrix per the

ALPHASET technology. This new solution greatly simplifies the preparations of materials difficult to machine.
