Brinell hardness test reference block MTV-MET

for micro Vickers hardness testsfor Rockwell hardness test

REFERENCE HARDNESS TEST BLOCKS Reference hardness test blocks warranty - 2 years PURPOSE Reference hardness test blocks (hereinafter referred to as hardness test blocks) are intended for the reproduction of metal hardness on Rockwell, Brinell, Vickers and Shore D hardness scales. The hardness test blocks are used at the calibration and verification of hardness testers. COMPLIANCE WITH INTERNATIONAL AND NATIONAL STANDARDS ISO 6506, ISO 6507, ISO 6508 ASTM E92, ASTM E384, ASTM E18, ASTM E10 GOST 9031, 8.064-94, GOST 8.063-07, GOST 8.062-85, GOST 8.516-01. VERIFICATION AND CALIBRATION Primary calibration of hardness test blocks is performed by VNIIFTRI - the National Metrological Institute of Russia. The verification interval is 2 years. DESCRIPTION The test blocks are manufactured in the form of rectangular or round plates from carbon or alloy steel. The test blocks are manufactured in МТR-МЕТ, МТSR-МЕТ, МТB-MET, МТV-MET, MМTV-MET and МТSh-MET modifications and intended for the reproduction of metal hardness on Rockwell, Super-Rockwell, Brinell, Vickers, micro Vickers and Shore D hardness scales respectively. МТR-МЕТ: Rockwell (HRA, HRB, HRC) МТSR-МЕТ: Superficial-Rockwell (HRN, HRT) МТB-МЕТ: Brinell (HB) МТV-МЕТ: Vickers (HV) МMТV-МЕТ: Micro Vickers (HV) МТSh-МЕТ: Shore (HSD) LABELING The following information is put onto the side surface of the hardness test block: Manufacturer's logo (Centre "МЕТ"); Verification month; Test block serial number assigned by the National Metrological Institute of Russia, which performed the calibration. Hardness value with an indication of the hardness scale.
