Electronic Crockmeter/Rubbing Fastness Tester is designed with a base, rubbing rotation mechanism and a counter. Fix the specimen and sand paper with the specimen clamp on one side of the base. Rotate the knob to rub the friction head with the white cotton cloth against the specimen in reciprocation motion with specified strokes. After ten times of friction between the white cloth and the specimen, assess the color transfer to the white cloth with a gray scale and the stability of dyed fabric specimen or surface coating so as to provide reference data for material assessing and selection.
Testing Standards: ASTM F1319, AATCC 8/165, BS 1006 D02, GB/T 3920, ISO 105 D02/X12, JIS L0849, M&S C8/C8A, NEXT TM6
Applications:
Electronic Crockmeter/Rubbing Fastness Tester is used to determine the colour fastness of cotton, chemical fiber, blended, other coloured fabrics and leather to dry or wet rubbing, suitable for frequent use and long run tests. A piece of dyed test cloth and a piece of white cotton cloth are rubbed against each other though the tester in a specific pressure and stroke.
The color fastness of the sample is graded by comparing the coloring of the white cotton with the gray scale. Fitted with digital electronic preset-table counter for strokes.
