Crockmeter, colour fastness to rubbing tester
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.
Available as either a hand operated or motorised instrument.
The rubbing finger is easy to load with crocking cloth by using a spring clip.
Apart from textile testing, the CrockMaster can be used to test the colour fastness to rubbing of carpets, laminates and printing inks.
It also tests the micro-scratch resistance of lacquers, coatings or painted surfaces.
The specimen clamp has been designed to be suitable for a wide variety of materials.
The weight to produce a loading of 9N is removable and alternative weights can be used.

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