This tester’s 104 ± 3 mm rubbing track helps keep the crocking path consistent from run to run, so dry and wet rubbing results are easier to compare across textiles, printed goods, and leather samples.
In practice, a fixed stroke geometry reduces operator-to-operator variation because the rubbing travel stays nearly the same on every specimen. That is one of the main reasons this style of crockmeter is used for routine QC and color transfer checks.
The track works alongside the 16 mm rubbing head, 9 N ± 0.2 N vertical pressure, 60 ± 2 rpm speed, and electronic stroke counting up to 9,999, which supports repeatable daily testing.
To align the setup with your method requirements, learn more or request a quote with your specimen type, finish, and target standard.
The 16 mm rubbing head helps keep the contact area and rubbing pattern consistent from test to test, which is what makes crocking results more repeatable. In a dry or wet rubbing fastness workflow, that consistency matters because even small changes in contact geometry can affect how much color transfer you see on the cloth.
On this tester, the rubbing head works as part of a controlled test setup with fixed pressure, track length, and stroke speed. That combination helps labs compare results more reliably across operators, shifts, and sample lots, especially in routine QC and batch verification.
To align this with your testing method, learn more about the system or request a quote for your sample type, standards, and setup.
The 60 rpm operating speed helps keep rubbing action consistent from one test to the next, which is important for judging color transfer in dry and wet crocking. In practice, that steady motion supports more repeatable results, so differences in stain or fading are more likely to come from the material itself, not from changes in the test stroke.
For textile colorfastness work, speed is one of the main factors that shapes the severity of the rub. When the motion is held at a controlled rate, labs can compare dyed fabrics, printed textiles, and leather samples more reliably across batches, operators, and test runs. That makes the result more useful for quality control, product development, and finish validation.
When refining your crocking method, it helps to confirm the full setup, including stroke count, pressure, specimen mounting, and the wet or dry cloth condition. You can learn more about the tester and request a quote if you want help matching the configuration to your test workflow.
On this tester, the stroke counter range is the number of rubbing cycles you can set before the unit stops automatically, up to 9,999 strokes. That makes it easier to run the same crocking sequence each time and compare dry or wet rubbing results consistently.
For test programming and repeatability, the main value is control, a preset count, fixed stroke geometry, controlled pressure, and a constant rubbing speed help keep operator-to-operator variation low. In practice, that supports routine QC checks, batch comparisons, and material development work.

Labs should treat ASTM D2054 and AATCC rub-fastness results as controlled color-transfer data, not as a broad rating of the fabric or leather by itself. This tester is meant for dry and wet crocking work, so the most useful interpretation comes from keeping the specimen mount, rubbing cloth condition, and test setup consistent from sample to sample.
For quality control, the result is best used to compare dye lots, finishing changes, printed textiles, or leather surfaces under the same method conditions. If your SOP ties the test to a specific AATCC 8 or ASTM workflow, the practical takeaway is that the setup must match the method details your lab follows, especially for dry versus wet rub testing and report formatting.
To align this with your method requirements, confirm the exact setup your lab wants to use, then compare the configuration against the application. You can learn more about this tester or request a quote for a configuration matched to your workflow.
