CrockMaster

Colour fastness to rubbing is the most basic of colour fastness tests, yet our Crockmaster is designed with exquisite attention to detail.

Our product designers focus on your testing needs to ensure that our instruments are both versatile and
simple to use. Available as either a hand operated or motorised instrument, Crockmaster is used to determine
colour fastness to wet and dry rubbing.

Description

James Heal’s CrockMaster is a crockmeter instrument used to determine colour fastness to wet and dry rubbing. It tests textiles, carpets, laminates, and printing inks, as well as the micro-scratch resistance of lacquers, coatings and painted surfaces. It is available in motorised and hand-operated models.

The Perfect Partners for CrockMaster

Crock Blocks

Crock Blocks are interchangeable fingers created to test textile floor coverings and other pile fabrics according the the standards ISO 105 x12 and AATCC 165.

Alternative Weights

Different loading weights are available for both models of CrockMaster, including 9N, 9.8N, 12N, 19N and 22.5N.

Crocking Cloth

The crocking test is based on assessing the amount of dye transferred from the specimen under test to a standardised crocking cloth. We supply pre-cut cloths to suit the differing requirements of ISO and AATCC standards.

Grey Scales

When the test is complete, an assessment of the amount of colour transferred to the crocking cloth is made with the aid of a grey scale.
