The TQC Buchholz Hardness Indentation Test provides a method for carrying out an indentation test on coatings complying with the ISO 2815-2003 standard. The TQC Buchholz Hardness Indentation Test consists of a calibrated slip-on weight with a sharp-edged metal wheel, an illuminated microscope, a level gauge, a digital dual timer, and two markers with template.
The calibrated slip-on weight with sharp-edged metal wheel is positioned on the test specimen for a set period of time. The length of the indentation mark in the coating is an indication of the hardness of the surface.
The Buchholz Hardness Indentation Test is a mandatory test in Qualicoat, QIB and GSB accredited laboratories.
