IULTCS Veslic Tester vs Crockmeter:

What are the Differences?

So many people often confuse IULTCS Veslic testers and crockmeters.

Knowing the differences and functions of both will help you choose the right equipment that your testing laboratory needs. It’ll also help you prioritize test accuracy and cost.

IULTCS Veslic Tester vs Crockmeter

What Is IULTCS Veslic Tester?

IULTCS Veslic Tester is an instrument that is built with touch‑screen control, sample tension fixtures, weighted rubbing finger and standard wool felt accessories. Basically, these devices together are used to perform dry and wet reciprocating abrasion tests for leather, plastic and textile samples. A IULTCS Veslic Tester can evaluate colour change of test sample and staining of white wool felt after specified rubbing cycles, to assess rubbing colour fastness for leather‑focused materials.

What Is a Crockmeter?

A crockmeter is an assembly of motor, circular rubbing head and sample holding fixtures. Together, this assembly drives the rubbing head to move back and forth across specimen surfaces. That is, a crockmeter determines textiles colour fastness to dry or wet rubbing and helps manage how rubbing test is performed for fabric materials.

Oftentimes, you’d find crockmeters in places with general textile quality control (following AATCC and ISO 105‑X12 standards). They are common in places like garment factories, textile testing labs, and apparel manufacturers.

Difference Between IULTCS Veslic Tester and Crockmeter

Difference Between IULTCS Veslic Tester and Crockmeter

There are marked differences between IULTCS Veslic testers and crockmeters, and the most distinct ones are:

Purpose

IULTCS Veslic Tester and crockmeters are produced for different reasons. IULTCS Veslic Tester evaluates rubbing colour fastness mainly for leather, synthetic leather and footwear materials under controlled sample tension, using wool felt as rubbing medium. Crockmeter, on the other hand, is solely made to test dry and wet rubbing fastness for general woven and knitted textiles with standard white cotton rubbing cloth.

Test Standards

Crockmeters are made to comply with standards mostly including AATCC 8, ISO 105‑X12, BS 1006‑D02, JIS L 0849 Type1. A IULTCS Veslic Tester follows ISO 11640, DIN 4843, SATRA PM173, EN ISO20344 section7.3 for leather and footwear upper testing. Because they follow completely different standard systems, you’d find a Veslic tester mostly in leather tanneries and footwear labs, while crockmeters are for textile and garment facilities.

Complexity

A IULTCS Veslic Tester is way more complex than a crockmeter on every level. For instance, aside from their components, most Veslic testers have advanced features like sample tension adjustment system (0‑20% tension range), touch‑screen operation, dual weight options (500g and additional 500g weight) and special wool‑felt rubbing finger with 15×15 mm contact area. Crockmeters are the simpler versions. They primarily only drive circular 16 mm rubbing head to rub fabric samples, so there’s no need for sample tension stretching mechanism.

Maintenance Needs

A IULTCS Veslic Tester is more taxing to maintain over time. With a Veslic tester, you need to carry out more frequent inspections for tension fixtures, weight calibration and wool felt replacement. This routine inspection helps it work better under leather test conditions. Crockmeters, in contrast, only need less attention and simpler routines to maintain them; you mainly replace cotton rubbing cloth and check motor stroke. Nevertheless, regular checks are still important for both machines.

Test Mechanisms

A IULTCS Veslic Tester ensures reliable leather test results, so it’s built with additional parts that make it more complex. Veslic tester stretches leather samples with defined tension, uses rectangular wool‑felt rubbing tip, applies selectable total load, runs at 40±2 strokes per minute with 35‑40 mm rubbing stroke.

For crockmeters, though, they test relaxed fabric samples without tension stretching, use circular 16 mm rubbing head with cotton rubbing cloth, fixed 9N vertical pressure, test speed at 60±2 rpm, 104±3 mm rubbing track.

Cost

Given the various inputs, designs, and complexities of a IULTCS Veslic Tester, it’s more expensive. Maintaining a Veslic tester will incur additional costs for you over time too, such as special wool‑felt consumables.

Crockmeters are much cheaper to buy and maintain, and standard cotton rubbing cloth is low‑cost consumable.

Use Cases

IULTCS Veslic Testers are best suited for situations where leather, synthetic leather, shoe upper material testing is required. Hence, you’ll likely find Veslic testers in tanneries, footwear factories, and material labs processing heavy‑duty leather goods.

Crockmeters are for general textile fabrics. They work better for garment factories, textile mills, apparel QC labs where fabric rubbing fastness is the main deal.

Why Choose GESTER IULTCS Veslic Tester and Crockmeter

With GESTER, rest assured that you’ll get safe and reliable IULTCS Veslic testers and crockmeters for your different project types. Whether you need a IULTCS & Veslic Leather Abrasion Tester or crockmeter for your garment factory, footwear plant, commercial testing laboratory, or tannery, GESTER instruments meet global standards. We are also committed to delivering equipment of reliable long‑term performance anywhere to you at a competitive cost.

Conclusion

IULTCS Veslic testers and crockmeters are really alike, but they are miles apart, different. The basic difference you must always keep in mind is that a IULTCS Veslic Tester is optimized for leather & shoe‑upper rubbing fastness testing with sample tension and wool felt. A crockmeter tests general textile fabrics with cotton rubbing cloth without sample stretching.

This difference, alongside others, will help you choose the right option for your project’s material type, required test standards, and, of course, your budget.

FAQs

Can Crockmeter handle leather testing like IULTCS Veslic Tester?

No, and quite frankly, it’s safer for you not to experiment to see if it works unless you are willing to risk getting non‑compliant test reports. Crockmeters are designed for general textile fabric testing under AATCC / ISO 105‑X12. IULTCS & Veslic Leather Abrasion Testers are the equipment designed to handle leather and shoe‑upper material per ISO 11640 and SATRA standards.

Can You Use IULTCS Veslic Tester for general textile fabric testing?

Not really. While Veslic testers can physically rub fabric samples, it’s best not to use them for routine textile fabric testing as most Veslic testers follow leather‑specific standards. For textile fabric buildings, it’s safer and cheaper to use crockmeters.

Which Is Better for Footwear & Leather Applications: Veslic Tester or Crockmeter?

Crockmeters may perform rubbing test, but a IULTCS Veslic Tester is more suitable. Most Veslic testers come with sample tension system, wool‑felt rubbing media and comply with footwear‑related test standards. This is usually absent in standard crockmeters.

What Is the Main Purpose of a IULTCS Veslic Tester?

The IULTCS Veslic Tester exists to evaluate dry and wet rubbing colour fastness of leather, synthetic leather and shoe‑upper materials by reciprocating abrasion with standard wool felt under specified tension and load.

Is Veslic Tester the Same as a Crockmeter?

No. IULTCS & Veslic Leather Abrasion Tester is not the same as a crockmeter. A crockmeter is rubbing fastness tester mainly for woven / knitted textiles. A IULTCS Veslic Tester is made to test leather and footwear‑related materials under dedicated leather test standards.
