EN ISO 4507:2007 Sintered ferrous materials, carburized or carbonitrided - Determination and verification of case-hardening depth by a micro-hardness test (ISO 4507:2000)
This International Standard specifies methods for determining the case-hardening depth of carburized or carbonitrided sintered ferrous materials by micro-hardness measurement.The methods are adapted to materials having porosity and only apply to quenched materials.
