The problem

Coating scratch resistance judged by fingernail; the standard tip geometry, angles and axial forces cannot be reproduced manually, so batches cannot be compared and disputes have no data.

Capability

Scratch test apparatus for enclosure coatings meeting IEC 60335-1 and GB/T 4706.1 clause 21.2. Hardened steel needle with 40-degree conical tip of 0.25mm plus/minus 0.02mm radius; needle angle to the horizontal adjustable 80-85 degrees; travel speed about 20mm/s; axial force 10N plus/minus 0.5N and 30N plus/minus 0.5N. Mitsubishi PLC with LCD panel and three-axis stepper positioning; stroke X 0-180mm, Y 0-200mm, Z drop 0-50mm, speed 0-100mm/s, counts 0-999999. Supplied with needle and pencil fixtures and weight sets for steel-needle scratch, pencil scratch, eraser and solvent rubbing tests. AC220V 50Hz.
