Rotary Crockmeter
Dairesel Krokmetre (Sürtme Haslığı)
Rotary rubbing motion for printed fabrics.
Model technical data
- Measures rubbing fastness by the colour change of the specimen and the staining of the accompanying fabric.
- Specimens are rubbed against dry, undyed cotton accompanying fabric.
- The staining ratio of the accompanying fabric is evaluated on the staining grey scale.
Physical specifications and utilities
| Electrical supply | Manual / passive base apparatus; no mains supply assumed. |
|---|---|
| Power / connected load | Approx. 0 W connected load for preliminary planning. |
| Overall instrument dimensions | Approx. 350 × 250 × 500 mm (W × D × H). |
| Instrument weight | Approx. 5–12 kg net. |
| Gross / shipping weight | Approx. 15.5–25 kg gross; estimated packing allowance. |
| Lab requirements | Level, stable working surface; specimen conditioning follows the selected method. |
Dimension order and approximate values are stated in each row. Packaging data are separate from instrument dimensions and net mass. Approx. rows are preliminary engineering estimates based on comparable equipment and function/capacity; they are not verified manufacturing measurements or standard requirements. Installation and shipment are finalised against the approved drawing and nameplate. Estimate scope: base product / one unit; external computer, bench and auxiliary plant excluded.
Specifications, dimensions, and power requirements are approximate and subject to change without prior notice for continuous design improvements.
Product technical specifications and images may vary according to manufacturing conditions and applicable standards.
Test and configuration
- Measured output / function
- Staining grade of rubbing cloth after rubbing
- Parameters selected for the method
- Rubbing head, load, motion and wet/dry condition
- Verification points
- Force, stroke, counter and reference cloth
Listed methods are application references. Suitability is established by assessing the selected hardware, current method and calibration together.
Test parameters for the reviewed method
Values belong to the stated source edition. Test recipe, fixture and delivered instrument configuration are selected together.
ISO 105-X16 (earlier edition) · 4.1
- Rotary rubbing uses 11.1 ± 0.5 N vertical force and 405 ± 3° motion; select the 25 ± 0.1 mm or the method's separate 16 mm finger.
AATCC 116-2005 · 5.2, 9.1-9.2
- Rotary vertical rubbing: downward force 11.1 N ±10%; crock cloth 51 × 51 mm. Wet pickup 65 ±5%; dry and wet results recorded separately.
Control and recording specification
The following are method-specific software/recording requirements; delivered software modules are defined by the order scope.
- The need for integrated software depends on the method and selected hardware; manual instruments use an external test record.
- Method code and edition, specimen ID, operator and selected test parameters are linked to the record.
- The calculation and endpoint are defined by the selected method edition; instrument signals and operator assessments are kept distinct.
- Raw measurements, units, valid/invalid test flags and the reported result remain traceable.
- Calculations are checked against known inputs and an independent calculation; sensor channels are checked against calibration values.
