Crockmeter TF411

4.75 (12 reviews)

Crockmeter – Electronic Mode, to determine the color fastness of textiles to dry or wet. This Electronic Crockmeter complies with ISO 105×12/D02, AATCC 8/165 testing standard, and etc. In the crocking test, a reliable Crockmeter plays a vital role in the repeatable and reproducible results.



The Electronic Crockmeter provides a labor-saving way to determine the amount of color transferred from the surface of colored textile materials and other dyed materials to another surface by rubbing. Designed with a stable slide offers you even testing results, and the weight which produces 9N loading is changeable to alternative weights  Crockmeter Fitted with a pre-determined electronic counter for strokes up to 999,999 times. For fewer times rubbing fastness testing, you can also choose a manual crockmeter as an alternative to this motorized one.


  • Rubbing head 16 mm
  • Vertical pressure 9N ± 10%
  • Rubbing stroke 104 ± 3 mm
  • Counter 1 ~ 999,999 times, automatically stop



  • The precision slide rail ensures the linear movement of the friction rod and the friction finger, avoiding the uneven staining test result.
  • Bigger size specimen brings even pressure on the sample, getting rid of the wrinkles when rubbing.
  • Parts such as switches, buttons and counting meters are imported from the US and Japan, meet strict test standards, and have stable performance.
  • Easy lift design makes it easy to change either Abradants or Specimens.
  • The cover is shielded to prevent dust and other debris from falling into the instrument and prolonging the service life.
  • Unique Handle design makes this crockmeter a real portable machine and friendly to female operators.



Different croking test method defines different testing abradants requirement, take AATCC Test Method 8 for example, A AATCC crocking cloth should meet the following specifications:

Fiber100% 10.3 - 16.8mm combed cotton staple, desized, bleached, with no optical brightener or finishing material present
Yarn15 tex (40/1 cotton count), 5.09 turns/cm "z"
Thread Count32 +/-3 warp ends/cm: 33 +/-3 picks filling/cm
Weave1/1 plain
pH7 +/-1
Mass/sq. meter100 +/-3 g finished
WhitenessW = 78 +/-3(TM110)

    Principle of color fastness to crocking

    According to the crockmeter test method, strapping dry or wet cotton cloth on the surface of the friction head of the machine with a metal buckle, make the sample rub with the white crockmeter test cloth for friction, contrast the gray card, compare the color degree of the white cotton cloth for friction with the gray-colored grade gray sample card, judgement the grade of colorfastness to crocking.

    Significance of crocking test

    Fabric friction can exist in our real life in various ways, such as the friction between fabric and lining when people wear clothing, friction in various splicing parts, friction when sitting on objects, and so on. These conditions are likely to affect the appearance of the garment and even endanger our health because of the poor rubbing fastness of the fabric, resulting in color transfer. The fastness to rubbing is closely related to our life and should be paid enough attention to.

    What is a crocking meter?

    The product crockmeter is a kind of test instrument that uses the test simulation environment to test the solid degree of the sample color. From the beginning of the manual friction tester to the present motorized crockmeter, from the testing of textiles to the testing of leather, colour fastness to rubbing test method become more and more(for more information on crockmeter testing, please refer to the crockmeter Wikipedia).

    Comparison of crockmeter

    At present, different countries adopt different crocking test standards. For example, the moisture content of wet friction in AATCC8 test method should be 65%, while the other standards are 95%~100%, and so on. The specific parameters of the different criteria are shown in the following table:

    According to the actual demand of production development and the difference between rubbing and crocking, At present, there are the following types of rub test machine: crock meter, which meets the crockmeter ASTM, product AATCC crockmeter, which conforms to the common standard, rubbing fastness tester, which conforms to the JIS standard, and IULTCS rubbing fastness tester, which can test the colour fastness to friction of leather.

    Q: How to use the crock meter tester?

    A: We have the crockmeter manual attached to our products. If you haven’t brought our product and you want to know more knowledge about crockmeter, we can send you an e-manual via e-mail. Please feel free to contact us.


    Q: What’s the difference between rubbing and crocking?

    A: There is no exact distinction between rubbing and crocking. You can refer to the ISO 105-X12:2016-Colour fastness to rubbing and AATCC test method 8-Colorfastness to Crocking.


    Q: Is the weight on top of TF411 can be taken off and measured as we need to calibrate?

    A: No. The weight above is just an aggravating weight. The total weight of the friction head is 9N. It contains the weight of the entire arm. We will check the weight before delivery and you cannot weigh it separately.


    Q: Is the friction speed of TF411 adjustable?

    A: No. Only one speed is specified in the standard: 60 rpm.
