This report describes the results of comparison COOMET.M.H-S5. The comparison measurements between the five participants NSC "IM" (pilot laboratory), PTB, CMI, BelGIM, RSE "KazInMetr" were started in November 2013 and ended in May 2015. In the RMO SC, one set of hardness reference blocks were used consisting of 5 (five) blocks of the Rockwell scales and hardness levels 80-86 HRA, 80-100 HRBW, 20-30 HRC, 40-50 HRC, 60-70 HRC. Agreement between results of participants is good. == Main text To reach the main text of this paper, click on Final Report [https://www.bipm.org/utils/common/pdf/final_reports/M/H-S5/COOMET.M.H-S5.pdf] .
