This motorised apparatus is dedicated to coatings hardness evaluation based on scratching resistance method. A test panel is clamped and slowly moved whilst a stylus or alternative tool scratches the surface. Depending on test procedures, specified or variable loads can be applied to obtain different degrees of failure, from trace to destruction. A voltmeter indicates the contact of the tool with the metallic sample substrate. Max. panel size : 100x150x1.6mm (0.3mm coating). Alternatively a simple manually operated version is also available.
- Robust construction, reliable and reproducible results
- Simple maintenance, easy to replace tools
- 220-240V / 50Hz (110-120V / 60Hz on request, please specify)
Specifications allow for use of either the (preferred) mechanised or hand operated apparatus. A test panel is clamped to a slide which slowly withdraws the panel while a needle scratches the surface. Tests are conducted either on a ‘go/no go’ basis using a single specified load or by increasing the load to determine the minimum load at which the coating is penetrated.
The Mechanised Scratch Tester (SH705) and the Manual Scratch Tester (SH706) have been updated to offer the weight set required by ISO 1518-1 (SH705/053/D). We continue to offer the weight set specified by the preceding international standard, ISO 1518, as spares (SH705/050/D).
Please contact us if you wish to purchase a replacement weight set to update your machine to ISO 1518-1.
