PLASTICS. DETERMINATION OF TENSILE PROPERTIES.

La présente norme décrit une méthode de détermination des caractéristiques en traction des plastiques thermoplastiques et thermodurcissables chargés ou non, renforcés ou non, souples ou rigides. Les plaques, films et feuilles minces dont l'épaisseur est inférieure à 1 mm, les matériaux à comportement caoutchoutique, les matériaux renforcés par des fibres longues unidirectionnelles en une ou plusieurs nappes, les structures sandwich, les matériaux alvéolaires et les allégés ne sont pas concernés par la présente norme. Les caractéristiques déterminées comprennent le module d'élasticité, la contrainte et l'allongement au seuil d'écoulement, la contrainte et l'allongement à la rupture. Cette méthode peut fournir des données pour le contrôle de qualité, pour la recherche et le développement.

Plastics - Determination of tensile properties - Part 4 : test conditions for isotropic and orthotropic fibre-reinforced plastic composites

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.

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
