Content

The Veslic Colorfastness Abrasion Tester is designed to evaluate colorfastness under rubbing (crocking) conditions for leather, finished textiles, and other coated or treated materials.

Application

It simulates real-world wear scenarios, such as foot rubbing, cross-legged seating, or material abrasion, using felt, rubber, abrasive papers, or fabric pads.

The system allows testing dry or wet, using distilled water or synthetic perspiration, and evaluates color change or marring against standard gray scales in controlled lighting conditions.

Test Standards

BS 1006 UK-LG – Colorfastness to Rubbing

DIN 53-339 – Textiles: Determination of Colorfastness to Rubbing

EN ISO 11640 – Leather: Colorfastness to Rubbing

IUF 450 / SLF 450 / Veslic C4500 / C4505 / C4580 – Industry-specific rubfastness testing protocols

Custom OEM or laboratory standards – Configurable per user requirements

Features and Advantages

Three Independent Stations: Allows simultaneous testing of multiple samples under the same or different conditions.

Customizable Test Loads: Each station supports 500 g standard load with additional 500 g optional weight.

Flexible Test Pads: Supports felt, rubber, abrasive paper, and fabric to simulate diverse abrasion scenarios.

Dry or Wet Testing: Accommodates water or synthetic perspiration for realistic material evaluation.

Accurate Color Assessment: Visual evaluation with gray scales under controlled lighting for standardized results.

Durable Construction: Non-corrosive aluminum and stainless steel components ensure long service life.

Adjustable Speed and Jog Controls: Fine-tune testing speed for specific protocols.

Operator Safety: Protective vented cover minimizes risk of injury during operation.

Friction Heat Management: Built-in down draft fan prevents temperature rise that could affect test accuracy.

High Reliability: Brushless motors and precision bearings ensure smooth, maintenance-free operation.

Test Procedures

Cut specimens and rubbing media according to the relevant standard and perform preconditioning if required.

Mount the specimen onto the clamp and apply the specified linear tension.

Select and install the felt pad or other specified rubbing medium.

Set the rubbing load, speed, and number of cycles.

Start the tester to perform dry or wet rubbing.

After completion, remove the specimen and rubbing medium.

Evaluate color change and color transfer using the grey scale under standard lighting conditions.

Record results and generate test documentation.

Maintenance Information

Regularly inspect felt pads and rubbing media; replace when worn or contaminated.

Keep clamps and rubbing heads clean to avoid cross-contamination between tests.

Periodically check fasteners, bearings, and drive components for proper operation.

Ensure the cooling fan is unobstructed to maintain thermal stability.

Store the instrument in a clean, dry environment when not in use.
