FGF Launches First Interlaboratory Study on Cold Crushing Strength
The Forschungsgemeinschaft Feuerfest e. V. (FGF) is launching its first “Interlaboratory Study (ILS)” for refractory products, with “Cold Crushing Strength (CCS)” selected as the first testing method. The new programme aims to improve the comparability, accuracy and reliability of refractory testing across different laboratories. Participants will receive homogeneous refractory brick samples prepared and distributed centrally by FGF. The laboratories will prepare their test pieces and determine the CCS according to a standardised procedure before submitting their results to FGF.
All data will be anonymised and statistically evaluated to assess precision, accuracy and comparability between the participating laboratories. Each participant will subsequently receive a detailed benchmark report, including insights into laboratory performance and, where appropriate, recommendations for improvement.
The ILS is open to the entire refractory value chain, including refractory producers, independent testing laboratories, refractory users such as steelmakers and foundries, as well as research institutions and associations. The CCS study marks the start of the programme. Interlaboratory studies for Modulus of Rupture (MoR) and Bulk Density (BD)/Open Porosity (oPo) are planned to follow.
Registration for the CCS interlaboratory study is open from 15 August to 15 October 2026.
