Product Description

In the Buchholz indentation hardness test a test body of specified geometry acts for a prescribed time on the specimen using a defined test load. After a specified recovery time the length (l) of the resulting indentation is measured using the microscope. Based on this length of impression (l) in mm, it is possible to calculate:
Buchholz indentation hardness = 100/l (1) ; Depth of impression (µm, approx.) = 8 x l² (2). The Buchholz Hardness Indentation Test is a mandatory test in Qualicoat, QIB and GSB accredited laboratories.
