Manual AATCC Crockmeter, to test the colour fastness of textiles to dry or wet rubbing.

Application

Crockmeter, to determine the colour fastness of textiles to dry or wet rubbing.

The new Crockmeter equipped with an electronic counter, and handle is on the top to take it easy. A sandpaper is set under the test sample so that the sample is fixed during the test, makes the rubbing colorfastness test repeatable.

How to Correctly Read the Gray Sample Card?

1.Calibration basis. GB / T 250-2008 (ISO 105 / A02-1993) “Gray Scale for Evaluating Color Displacement” sets the quantitative requirements for the accuracy and effectiveness of a gray swatch:

  • The tristimulus value Y for each pair of the first group should be 12 ± 1
  • Each pair of the second component along with the first component has color difference provisions which can be seen in the chart below:
Durability Level (Degree)CIELab Color DifferenceTolerance
500.2
4~50.8±0.2
41.7±0.3
3~42.5±0.35
33.4±0.4
2~34.8±0.5
26.8±0.6
1~29.6±0.7
113.6±1.0

(Gray card calibration qualified technical indicators)

2.Calibration items. The calibration items are mainly Y values and CIELab color differences. Y value refers to the color brightness; CIELab color is the International Commission on Illumination (CIE) adopted a set of color formula, called CIE1976 * a * b *.

3.Calibration method. The colorimeter was used to determine the Y value and the CIELab color difference for each set of gray card color difference levels. Compare whether the Y value is in the range of 12 ± 1, and whether the CIELab color difference value meets the requirements in the tolerance range of Table 11-1 to determine the validity of the gray card.
