The Palmqvist indentation cracking test is sometimes used for the characterization of the toughness of cemented carbides. The test provides a measure of the indentation crack resistance of a brittle material (from the length of cracks induced at a hardness impression and the applied load), namely, W = P/L/sub T/, where W is the surface crack resistance, P is the load on a Vickers diamond indenter, and L/sub T/ is the total length of the surface cracks emanating from the corners of the indentation.
