Model: GC-HQY-96
A. Features:
1. This instrument adopts micro-processing control and integrated and digital measurement and control technology. Procedural setting according to the standard test procedure.
2. Ball indentation hardness means that a steel ball with a specified diameter is vertically pressed into the surface of the sample under the action of the test load and kept for a certain period. Finally, the average pressure per unit area is expressed in Kgf/mm2 or N/mm2.
Its expression is: H=0.21p/0.25πD (h-0.04) (kg/mm2)
P-load (kg)
h-indentation depth (mm)
D-Steel ball diameter (mm)
π - pi
Note: h=h1-h2
h1: Indentation depth of sample load (mm);
h2: The frame deformation of the instrument under the test load (mm)
3. The distance between the center of the measurement point and the edge of the sample is not less than 10mm, and the distance between the centers of two adjacent measurement points is not less than 10mm
