This document specifies the test conditions for the determination of the tensile properties of isotropic and orthotropic fibre-reinforced plastic composites, based upon the general principles given in ISO 527-1. NOTE 1   Unidirectional reinforced materials are covered by ISO 527-5. The methods are used to investigate the tensile behaviour of the test specimens and for determining the tensile strength, tensile modulus, Poisson's ratios and other aspects of the tensile stress-strain relationship under the defined conditions. The test method is suitable for use with the following materials: —    fibre-reinforced thermosetting and thermoplastic composites incorporating non-unidirectional reinforcements such as mats, woven fabrics, woven rovings, chopped strands, combinations of such reinforcements, hybrids, rovings, short or milled fibres or preimpregnated materials (prepregs); NOTE 2   Injection moulded specimens are covered by ISO 527-2. —    combinations of the above with unidirectional reinforcements and multidirectional reinforced materials constructed from unidirectional layers, provided such laminates are symmetrical; NOTE 3   Materials with completely or mainly unidirectional reinforcements are covered by ISO 527-5. —    finished products made from materials mentioned above. The reinforcement fibres covered include glass fibres, carbon fibres, aramid fibres and other similar fibres.

This International Standard specifies a method for determining the durability of the adhesive joints of carbon fibre reinforced plastics (CFRPs) and metal assemblies by a wedge rupture test using a double cantilever beam (DCB) specimen under specified environmental conditions. This method is intended for evaluating the safety and reliability of adhesives, primers, and surface treatments of the adherends.

This document establishes a basis for a specification for sheet moulding compound (SMC) used in the production of composite parts by hot moulding.
It is suitable for sheet moulding compound with glass fibre (GF) and carbon fibre (CF) as the sole or main reinforcement.
It should be noted that the term sheet moulding compound covers products which can be complex mixtures and which may differ from the definition of “mat” given in ISO 472.
