Veslic Rub Fastness Tester
Veslic Rub Fastness Tester
Veslic Rub Fastness Tester is a laboratory testing instrument designed to evaluate the colour fastness, surface behaviour, and resistance of leather and other suitable materials against controlled dry or wet rubbing. It helps manufacturers and testing laboratories assess colour transfer, surface change, and finish durability through repeatable rubbing cycles.
OVERVIEW
Description
Veslic Rub Fastness Tester
The Veslic Rub Fastness Tester is a laboratory testing instrument used to evaluate the behaviour of leather and suitable coated materials when subjected to controlled to-and-fro rubbing. The test helps determine whether the surface finish or colour of a material remains stable when exposed to repeated rubbing during normal handling and use.
The instrument works by applying controlled rubbing between the test specimen and a suitable wool felt rubbing pad. After a defined number of rubbing cycles, the sample can be examined for colour change, surface damage, marring, and colour transfer to the rubbing material. Testing can be performed under dry or wet conditions according to the applicable test procedure.
The Veslic rub test is widely associated with leather colour-fastness evaluation and is covered by recognised testing methods including ISO 11640. The equipment can be useful for leather manufacturers, footwear manufacturers, textile and material laboratories, automotive component manufacturers, and quality-control departments.

How Does the Veslic Rub Fastness Tester Work?
The test specimen is securely positioned on the testing platform. A suitable wool felt rubbing pad is placed against the material surface under the required test conditions. The machine then produces controlled reciprocating rubbing motion for the specified number of cycles.
During the test, the repeated rubbing can reveal changes in the surface finish or colour of the specimen. The rubbing pad may also show colour transfer from the tested material. After testing, the specimen and rubbing material can be evaluated using the appropriate assessment method, such as a grey scale where applicable.
This controlled process provides a practical way to compare material performance and identify differences between production batches, finishes, colours, or material formulations.
Key Benefits
Consistent Rubbing Test
The machine provides controlled reciprocating rubbing movement, helping laboratories perform repeatable tests on material samples.
Dry and Wet Testing
The equipment can be used for dry or wet rubbing evaluations when the selected testing method requires these conditions.
Surface Finish Evaluation
It helps identify visible changes, marring, fading or deterioration of the tested surface following repeated rubbing.
Colour Transfer Assessment
The rubbing pad can be examined for colour transfer from the test specimen, providing useful information about colour fastness.
Suitable for Quality Control
The tester can be used as part of incoming material inspection, production quality control, product development and comparative testing.
Laboratory-Friendly Operation
The equipment is designed for controlled laboratory testing and can be supplied according to the required test configuration.

Standards and Testing Methods
The Veslic rub test is associated with internationally recognised leather testing procedures. ISO 11640 specifies a method for determining the behaviour of leather surfaces when subjected to cycles of to-and-fro rubbing with wool felt.
Depending on the machine configuration and customer's testing requirements, Veslic-type equipment may also be supplied for testing procedures associated with standards such as:
- ISO 11640
- EN ISO 20344
- ISO 17700
- IUP 450
- IUF 450
- DIN 53339
- SATRA PM 173
The exact standards applicable to a particular test should always be confirmed against the latest edition of the relevant standard and the required machine configuration.

Frequently Asked Questions
What is a Veslic Rub Fastness Tester?
A Veslic Rub Fastness Tester is a laboratory instrument used to evaluate the colour fastness and surface behaviour of leather and other suitable materials when subjected to controlled repeated rubbing.
What does the Veslic test measure?
The test can be used to evaluate colour transfer, colour change and visible surface changes resulting from repeated rubbing. ISO 11640 specifically covers colour fastness of leather to cycles of to-and-fro rubbing.
Can the Veslic Rub Fastness Tester perform wet and dry tests?
Yes. Veslic-type testing can be performed under dry or wet conditions depending on the applicable test procedure and machine configuration.
Which materials can be tested?
The tester is primarily associated with leather testing. Depending on the selected configuration and test method, it may also be suitable for coated fabrics, synthetic leather, plastics and other surface-finished materials.
What is used for rubbing during the test?
A suitable wool felt or specified rubbing pad is generally used as the rubbing medium. The exact material and condition of the rubbing pad should follow the applicable testing standard.
Why is colour transfer evaluated?
Colour transfer provides an indication of how the surface colour or finish behaves when subjected to rubbing. This information can be useful for product development and quality control.
