Taber Crockmeter Rubbing Tester
Measures the amount of colour transfer from rubbing
Easy to use, rugged design with an established rating scale that standardizes evaluation and facilitates repeatable results.
The Taber Crockmeter (Model 418) is a relatively simple rub tester commonly used to determine the amount of color transferred from textile materials to other surfaces by rubbing. It can also been utilized to conduct smudge or smear resistance tests on images produced by a printer or copier. For paints and coatings, the crockmeter is useful when evaluating the change in gloss due to rubbing,scuffing or marring.
A test sample is clamped to the instrument base and a square of standard crocking cloth is fixed to a 16mm diameter, acrylic rubbing finger. The finger rests on the sample with a pressure of 900 grams force and traverses a straight path approximately 100mm long with each stroke of the arm.
After testing textile materials, the crocking cloth is removed and compared against the AATCC Gray Scale for Staining or Chromatic Transference Scale. Based on this comparison, the operator assigns a grade to the color change or amount of color transfer.
