This European Standard specifies the minimum general information to be declared for materials to be used for manufacturing fibre-reinforced plastic composites products. This document includes requirements for the certificate of analysis (CoA). The purpose of the CoA is to verify that material properties and quality conforms to the declared values. This part of the standard is applicable to resins, curing systems, additives and modifiers, fibres, fabrics and core materials. The current version of the standard includes the following: - the thermoset resins polyesters and vinyl esters; - glass and carbon fibres; - knitted/stitched fabrics; - foam core and balsa core.
