Plastiques - Film et feuille - Détermination de la résistance au déchirement - Partie 2: Méthode Elmendorf (ISO 6383-2:1983)

1.1 La présente Norme internationale spécifie une méthode de détermination de la force nécessaire pour propager un déchirement sur une distance définie, à partir d'une fente définie, pratiquée sur une éprouvette d'une feuille flexible ou d'un film, dans des conditions définies de mise en charge. L'épaisseur maximale qui peut être soumise à l'essai est fonction du niveau de la force de déchirement du matériau par rapport aux performances de la machine d'essai. Les feuilles et films à base de polychlorure de vinyle (PVC) flexible et de polyoléfine font partie des matériaux qui peuvent être soumis à l'essai selon cette méthode, mais, pour les films les plus extensibles, l'effet de l'allongement variable et du déchirement oblique peut entraîner une mauvaise reproductibilité des résultats. La méthode peut ne pas être appropriée pour essayer les matériaux plus rigides, par exemple les films de PVC rigide, polyamides et polyestériques. 1.2 L'essai de résistance au déchirement spéc

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of
national Standards bodies (ISO member bedies). The work of developing International
Standards is carried out through ISO technical committees. Every member body
interested in a subject for which a technical committee has been authorized has the
right to be represented on that committee. International organizations, governmental
and non-governmental, in liaison with ISO, also take part in the work.
Draft International Standards adopted by the technical committees are circulated to
the member bodies for approval before their acceptance as International Standards by
the ISO Council.
International Standard ISO 6383/2 (formerly ISO/DIS 6824) was developed by
Technical Committee ISO/TC 61, plastics, and was circulated to the member bodies in
February 1980.
lt has been approved by the member bodies of the following countries:
