Brinell Hardness Number

Overview: 
 
    	
  • 	
    Standard test from material testing industry adapted to rock testing to serve as an indentation strength index. 
    	
    • 	
  • 	
    Performed as per ASTM E10 and complies with the indentation testing requirements of ISRM Blue Book. 
    	
    	
  • 	
    End faces have to be flat for ideal indentation. 
    	
    • 	
  • 	
    Index can be utilized to develop correlations with UCS or tensile strength value to create continuous profiles of the strength index.
