Additional information
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.
