Le présent document décrit des méthodes d’essai sous contraintes biaxiales pour la détermination des propriétés de rigidité à la traction de supports textiles revêtus à orientation biaxiale (propriétés suivant les sens anisotropiques comme les fils de trame et de chaîne pour les supports textiles revêtus tissés, ou suivant les rangées et colonnes de mailles des supports textiles revêtus tricotés).
D’autres propriétés mécaniques (comme les valeurs de compensation du patronage, la rigidité au cisaillement et la résistance) seront décrites dans d’autres parties.

Introduction
Conventional mechanical test methods (based on uniaxial method) are not always suitable within the
purpose of the design of specific products using coated fabrics such as architectural tensioned covers.
1 Scope
This document describes methods of test using biaxial stress states for the determination of the tensile
stiffness properties of biaxially oriented coated fabrics (properties along anisotropic directions, such as
the weft and warp yarns for woven based coated fabrics, or along the courses and wales of knitted based
coated fabrics).
Other mechanical properties (such as pattern compensation values, shear stiffness, and strength) will be
described in other parts.
