Tissus de renforcement — Détermination de la rigidité conventionnelle en flexion — Méthode du flexomètre à angle fixe

ISO 4604:2011 specifies a method of determining the conventional flexural stiffness of reinforcement fabrics by means of a fixed-angle flexometer. This method is not suitable for testing fabrics that are limp or that have a marked tendency to curl or twist or fray.
