Q1: What is the main difference between the Wyzenbeek Test (GT-C71) and the Martindale Test?
A: Mechanism & Market: wyzenbeek abrasion tester GT-C71 utilizes linear oscillatory drum rubbing on curved samples (standard under ASTM D4157 in North America, required by ACT for commercial upholstery). Martindale uses multidirectional Lissajous motion on flat samples (ISO 12947 in Europe/global). As a direct physical testing machines manufacturer, GESTER produces both systems—including our Martindale Abrasion & Pilling Tester GT-C13—to meet various international standards.
Q2: What is considered a "Double Rub" on the Wyzenbeek GT-C71 machine?
A: A single "double rub" consists of one forward arc motion and one backward arc motion of the oscillating drum across the fabric sample under specific tension and load.
Q3: How many double rubs indicate heavy-duty commercial fabric performance?
A: According to the Association for Contract Textiles (ACT) guidelines:
General Contract: 15,000 double rubs.
Heavy Duty: 30,000 double rubs or higher (often 50,000 to 100,000+ double rubs for healthcare and high-traffic environments).
Q4: Does the GT-C71 come with a calibration report for ISO 17025 lab audits?
A: Yes. Each GT-C71 undergoes rigorous factory testing—including stroke, tension, and speed verification—and ships with a traceable calibration report to support lab accreditation.
Q5: Does GESTER provide other types of textile friction and abrasion testers?
A: Yes. Beyond the Wyzenbeek GT-C71, GESTER manufactures a comprehensive line of textile abrasion testers, including Martindale Abrasion Testers, Crockmeters (Color Fastness to Rubbing), and Taber Abrasion Tester, serving as a one-stop equipment supplier for textile testing laboratories worldwide.
