Crockmaster

The crockmaster was developed to determine the colour fastness to wet and dry rubbing of textiles. Nowadays it is also well accepted in the plastic industry to evaluate the scratch and abrasion resistance of plastic surfaces.

On a round shaped cylinder with a diameter of 16 mm, a crocking cloth is fixed. This cylinder with a loading weight of 6 N, will apply a defined number of strokes on the surface of the specimen. The number of strokes can vary dependent on the plastic article which has to be evaluated. In general 10, 50, 100, 500, 1000 and / or 2000 strokes are usual.

This method comply with EN ISO X12, AATCC 8 and M&S C8 and can be is applied to soft and hard material.
