1. Function and Application
The“W” Flex / Flex-O-Meter is designed to evaluate the flexural fatigue resistance of fabrics and leather. It simulates repeated bending and rolling of materials to measure durability, stiffness, and resistance to flex-induced damage.
The tester is suitable for automotive, upholstery, footwear, and other leather or fabric applications where repeated bending and rolling occur during use.
2. Applicable Test Standards
ASTM D2097 – Standard Test Method for Flexing Fatigue of Fabrics
GM 9216P, GM 9226P (withdrawn 2011) – Automotive fabric flexing
ISO 7854 Section B – Leather flexing
Jaguar JLR 52.413 – Automotive leather flexing
TSL 5101G Section 3.14.2B – Toyota leather/fabric flexing
MS 300-05 – General automotive material flexing requirements
