This set of specimens is available as an accessory for the WP 300 and WP 310 experimental units. The specimens have a square shape.
When used with WP 310, the WP 310.01 experimental setup is also required. This experiment setup consists of a pressure plate for holding the specimens and a mechanism for the hardened steel ball.
In the experiment the specimen is positioned on the pressure plate and a hardened steel ball is pressed into the specimen under defined conditions.
A triaxial stress state develops in the specimen, underneath the impressing test body. Then the surface or depth of the lasting impression is measured optically. The Brinell hardness is calculated from test load and impression surface of the spherical segment.
The WP 300.12 measuring magnifier is available as an accessory for the optical measurement of the imprint surface.
The set contains four aluminium specimens.
