The TQC Spring Loaded Roller is used to perform objective dust tests according ISO 8502-3, and eliminates the human error by pressing with a constant force on the dust test tape. The ISO 8502-3 quantifies the quantity and size of dust particles on surfaces prepared for painting using a standarized tape for dust test. Dust on blast cleaned surfaces can reduce coating adhesion, leading to premature coating failure and sub-standard coating finish.

The Spring Loaded Roller presses the tape onto the surface with a constant force of 44,13 Newton (4,5kg) by means of a spring system, four wheels, and a special rubber roll with a specified hardness. The apparatus is made of titanium anodised aluminum.

The TQC Dust Test Kit, is available separately.
