Kritické srovnání výsledků zkoušek tvrdosti podle Rockwella HRB.

Abstract

The aim of this diploma thesis was to map proficiency testing of testing laboratories by interlaboratory comparison, especially then approaches to assessment of interlaboratory comparison tests. Individual methods were confronted in terms of assessment of the Rockwell HRB hardness test results by using selected approaches and the most suitable for physico - mechanical tests area was determined. Priority was given to „Z-score“ over „En-number“ and classical statistics.
