Micro / Macro Scratch tester Qscratch 20 Test Methods & Force Range
Method Progressive load
The initial and final loads, as well as the load rate, are defined. The load increases along the scratch length; visible events can be assigned as Lc points at their respective positions.
ISO: PFST - progressive force scratch test
ASTM: PL - progressive load
Lc: Load critical
Method Constant load
The normal force remains constant over the scratch length. This method is suitable for individual measurements, series compa-risons, and recurring test conditions in a quality control setting.
ISO: CFST - constant force scratch test
ASTM: CL - constant load
Lc: Load critical
Test methods Progressive or constant load - tailored to the test requirements
Standards & Procedures

Test principle DIN EN ISO 20502 | ASTM C1624 A defined scratch. A controlled load. A clear evaluation.
The principle
In the scratch test, a diamond stylus is moved across the coated surface under a defined normal force. Visible events such as cracking, spalling, or penetration of the coating are localized along the scratch mark and assigned to the corresponding critical load. Thus, the scratch mark not only indicates that a failure is occurring; it also shows where it is occurring—and makes the load at the critical point traceable.
Defining and assigning failure events
Lc1 - Initial cracking / plastic deformation
Lc2 - Spalling
Lc3 - Penetration of the coating down to the substrate

Micro / Macro Scratch tester Qscratch 20 Revolutionary optic system
The QATM-developed, in-house manufactured lens system sets new standards. As well as providing crystal clear image quality for hardness testing, Koehler illumination uses white LED light and motor-operated aperture shuttering to produce ideal contrast, even for high magnification images.
Experienced metallurgists agree the image quality provided by the Qscratch is comparable in all aspects with that of established sophisticated microscopes. The up-to-date concept and new lenses in the optic system enable the device to completely meet even the strictest physical ‘test system definition’ requirements in compliance with DIN EN ISO6507-1/2:2018.
Micro / Macro Scratch tester Qscratch 20 Innovative Operation
8-position automatic tool changer
The motorized tool changer can accommodate up to three scratch test modules and up to seven lenses. This allows for overview, detailed inspection, and Lc determination to be performed directly within the scratch test sequence—on a single axis and without offset.
Vertical concept with 2 Z-axes
There are decisive benefits in distributing vertical movement across 2 axes. Via the first Z-axis there is dynamic motion control, allowing the indenter to be positioned towards the test surface quickly and conveniently at up to 30mm/s. The additional second Z-axis in the QATM system offers a high-resolution positioning system for greater precision in force application and focusing.
Test space lightning
CAS Technology
Innovative Collision Avoiding System (CAS) technology protects the mechanical parts in the device using predictive 3D motion calculations to visualize the effects of collisions and operation errors.
Digital caliper
The digital caliper is compatible with the Qpix Control2 system and reads the dimensions, height and diameter of components wirelessly and at the push of a button, entering them into the software. The test head height control in the A+ hardness tester enables the test height to be reached completely automatically with no need for manual input.
Illuminated status display Brings light into the dark
The illuminated QATM logo displays the current device status at a glance. The range of flash intervals indicates whether the device is operating automatically or is free to be used for new tasks for staff all around the lab. In addition, the LED test space lighting, installed as standard, ensures that samples and sample holders are positioned correctly.
On the Qscratch 20, it also ensures uniform light intensity for sample imaging.
Micro / Macro Scratch tester Qscratch 20 Pioneering technology - Unique implementation
Evaluable and comparable
The selected loading logic is linked to the scratch mark, position, and result. Methods can be applied to sample series, coating variants, and process comparisons.
Checking the diamond stylus
The diamond tip can be visually inspected directly within the system. This allows the condition of the diamond stylus to be checked before or after the test - an important step for ensuring reproducible results and traceable test conditions.
Universal sample holder
Adjustable clamping jaws allow for the secure holding of various specimen geometries - from flat and angular test pieces to round or very small specimens.
High-resolution sample image (HRI)
If high-quality images of larger areas are required (e.g. for weld seam measurements), the area can be scanned using the HRI function. The Qpix Control 2 software automatically combines the individual images into one large overall image.
Sample image camera
It’s no coincidence that most QATM customers choose the ‘A+’ version with a built-in sample image camera. In a few seconds the image of the sample is shot with the additional camera (field of view 52 x 39 mm). The image provides excellent navigational support within the software, particularly in combination with DOUBLE-VIEW TECHNOLOGY, and aids enhanced documentation in the automatically compiled test report.
Precise distance / Force application
Precise electronic load control ensures that the test load—as a critical test parameter—remains controlled, reproducible, and traceable at all times.
Scratch workflow Easy testing, efficient analysis
QpixControl2 is more than just a user interface: The software combines a patented 3D user concept with a seamless scratch workflow. Tests can be easily created, scratch marks visually positioned, single or multiple measurements processed automatically, and relevant Lc events evaluated in a structured manner. From test definition through image capture and evaluation to data management, export, and standardized reporting, all steps remain integrated within an intuitive software environment. This reduces operational effort, supports reproducible processes, and enables the efficient use of scratch testing in production-oriented quality assurance.
From setup to report 3 Steps to the result
1. Load sample
The sample holder is automatically moved to the correct height, and the sample image is automatically captured.
2. Positioning
Drag and drop the starting point of the scratch test directly to the desired position.
3. Start Test Sequence
The test sequence is fully automatically and in accordance with the Scratch test standards. Subsequently, the failure events can be evaluated and assigned to the respective Lc points.

Microscopy & Analysis
Qpix Control2 Innovative software functions
Single and multiple inspections
Single or multiple measurements: Scratch marks can be positioned directly in the software, created with a defined offset, and processed automatically. The Lc results are evaluated for each test as well as as a series mean.
A wide range of setting options
Load definition, crack length, load rate, speed, and lens selection are managed directly within the method. For evaluation, standardbased templates or custom templates can be used and supplemented with limit and target values.
Guided Lc determination
Graphical templates support the consistent classification of typical failure events. This facilitates standard-based procedures and reduces room for interpretation.
Force/Distance graph
The force-distance curve documents the applied load along the scratch track. Anomalies in the curve can be compared with visible failure events and used for Lc evaluation
Lc details
Relevant failure events along the scratch track can be viewed in detail in the image and assigned to the corresponding Lc details. This transforms the visual assessment into a verifiable test result
Report
Test parameters, scratch track, Lc values and evaluation results are compiled into a test report. This simplifies documentation, the comparison of test series, and the dissemination of results within the quality process.
