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.
