Medical Abrasion Laboratory Testing: Veslic Testing
Veslic testing measures the color fastness and rub resistance of leather and leather-like materials using controlled to-and-fro rubbing. This specialized method closely simulates repeated mechanical contact, cleaning, and wear that these surfaces experience in real-world use. For medical device and equipment manufacturers, strong Veslic performance ensures that leather components maintain their appearance, cleanability, and durability throughout their service life.
Leather and synthetic leather materials appear in many medical products, including instrument handles, orthopedic braces, wheelchair armrests, medical furniture upholstery, patient positioning straps, and reusable device covers. Veslic testing evaluates how well these materials resist color transfer, surface damage, and degradation when subjected to repeated rubbing with wool felt or cloth under controlled conditions, often combined with disinfectants or sweat simulants. Reliable Analysis already holds accreditation for ISO 11640 Veslic testing, providing an immediate capability to support medical applications.
This type of evaluation is important for both regulatory compliance and practical performance in healthcare environments. It helps manufacturers demonstrate that leather or coated components will not discolor, stain, or degrade when exposed to frequent handling, cleaning, and body contact. Reliable Analysis delivers consistent, reproducible results using equipment already in daily operation under our ISO/IEC 17025 accreditation.
Common Veslic Medical Testing Standards:
ISO 11640 Leather Color Fastness to Cycles of To-and-From Rubbing (Veslic method)
ISO 11640 determines the color fastness of leather to repeated to-and-fro rubbing using a Veslic tester. The method applies a standardized wool felt or cloth pad under controlled pressure and speed while evaluating color change on the leather and staining on the rubbing material. This test is widely used for leather and leather-like materials in medical applications such as instrument handles, orthopedic braces, wheelchair components, and medical furniture upholstery that require durable surface appearance after frequent contact and cleaning.
ISO 11640 Synthetic Leather and Coated Fabrics
ISO 11640 is also applied to synthetic leather and coated textiles using the same Veslic to-and-fro rubbing procedure. The test assesses color transfer, surface damage, and coating integrity under repeated mechanical action. Medical manufacturers rely on this method to qualify synthetic leather components in patient positioning aids, reusable straps, medical bags, and device covers that must maintain appearance and performance during extended clinical use and disinfection.
DIN EN ISO 11640 European Adoption of the Veslic Method
DIN EN ISO 11640 is the European harmonized version of the Veslic rubbing fastness test. It follows identical procedures but meets EU regulatory expectations for medical devices. The test verifies that leather and synthetic leather materials will not release color or show visible wear when subjected to repeated rubbing, supporting MDR compliance for wearable medical products and patient-contact surfaces.
ISO 11641 Leather Color Fastness to Perspiration Combined with Veslic Rubbing
ISO 11641 evaluates the color fastness of leather to perspiration, often combined with mechanical rubbing similar to the Veslic method. Specimens are treated with artificial sweat solutions and then subjected to controlled friction. This combined approach is particularly relevant for leather components in wearable medical devices, braces, and seating that experience prolonged body contact and sweat exposure in clinical environments.
ASTM D2054 Colorfastness of Zipper Tapes to Crocking
ASTM D2054 measures colorfastness to rubbing for components such as zipper tapes and can be adapted for leather or coated leather elements. The test applies standardized rubbing action to evaluate dye transfer and surface durability. It supports quality assurance for leather accents on medical garments, restraints, and reusable textile devices where long-term appearance and cleanliness are important.
