This publication was last reviewed and confirmed in 2026.

Hardmetals — Palmqvist toughness test

Description

This document specifies a method for measuring the Palmqvist toughness of hardmetals and cermets at room temperature by an indentation method. This document is applicable to a measurement of toughness, called Palmqvist toughness, calculated from the total length of cracks emanating from the corners of a Vickers hardness indentation, and it is intended for use with metal-bonded carbides and carbonitrides (normally called hardmetals, cermets or cemented carbides). The test procedures specified in this document are applicable for use at ambient temperatures, but can be extended to higher or lower temperatures by agreement. The test procedures specified in this document are also applicable for use in a normal laboratory-air environment. This document is not applicable for use in corrosive environments, such as strong acids or seawater.
