This document specifies a method for the determination of tear resistance of nonwovens by the trapezoid method. This document applies to nonwovens.
Abstract
Overview
ISO 9073-4:2021 specifies a standardized laboratory test method for determining the tear resistance of nonwoven materials using the . The document defines specimen preparation, conditioning, test equipment and operating parameters, data treatment and minimum reporting information. It applies to nonwovens and is intended for consistent, repeatable measurement of tear resistance (tear force) in both machine and cross directions.
