Testing of welded joints of thermoplastics semi-finished products - Part 4: Peel test

This standard specifies the dimensions, the method of sampling, the preparation of the test specimens, and also the conditions for performing the peel test perpendicular to the weld in order to determine the peel resistance and the failure behaviour.
A peel test may be used in conjunction with other tests (e.g. tensile creep, macro...) to assess the performance of welded assemblies, made from thermoplastics materials.
Peel tests are applicable to overlap welded assemblies made from thermoplastics materials, irrespective of the welding process used.

Prüfen von Schweißverbindungen aus thermoplastischen Kunststoffen - Teil 4: Schälversuch

Die vorliegende Norm legt die Maße, das Verfahren für die Probenahme und die Herstellung von Probekörpern sowie die Bedingungen für die Durchführung des Schälversuches senkrecht zur Schweißnaht fest, um den Schälwiderstand und das Versagensverhalten zu bestimmen.
Ein Schälversuch darf in Verbindung mit weiteren Prüfungen durchgeführt werden (z. B. Zeitstand-Zugversuch, Makroskopische Untersuchung, ...), um die Gebrauchstauglichkeit von geschweißten Verbindungen aus thermo-plastischen Kunststoffen zu beurteilen.
Schälversuche sind unabhängig vom angewendeten Schweißverfahren auf Überlappschweißverbindungen aus thermoplastischen Kunststoffen anwendbar.

Essai des assemblages soudés sur produits semi-finis en thermoplastiques - Partie 4: Essai de pelage

La présente norme spécifie les dimensions, la méthode d'échantillonnage, la préparation des éprouvettes, ainsi que les conditions d'exécution de l'essai de pelage perpendiculairement à la soudure pour déterminer la résistance au pelage et le comportement à la rupture.
Un essai de pelage peut être utilisé en combinaison avec d'autres essais ou examens (par exemple essai de fluage, examen macroscopique, ¿) pour évaluer les performances d'assemblages soudés en thermoplastiques.
Les essais de pelage sont applicables aux assemblages en thermoplastiques soudés à recouvrement, quel que soit le procédé de soudage utilisé.
