Testing of welded joints of thermoplastics semi-finished products - Part 7: Tensile test with waisted test specimens

This standard specifies the dimensions, the method of sampling, the preparation of the test specimens and the conditions for performing the tensile test with waisted test specimens in order to determine the tensile energy welding factor. A tensile test with waisted specimens may be used in conjunction with other tests (e.g. bend, tensile, tensile creep, macro...) to assess the performance of welded assemblies, made from thermoplastics materials.

Prüfen von Schweißverbindungen aus thermoplastischen Kunststoffen - Teil 7: Zugversuch an Probekörpern mit Rundkerbe

Die vorliegende Norm legt die Maße, das Verfahren für die Probenahme und die Herstellung von Probekörpern sowie die Bedingungen für die Durchführung des Zugversuchs an Probekörpern mit Rundkerbe fest, um den Energie bezogenen Kurzzeitzug-Schweißfaktor zu bestimmen. Ein Zugversuch an Probekörpern mit Rundkerbe darf in Verbindung mit weiteren Prüfungen durchgeführt werden (z.B. Biegeversuch, Zugversuch, Zeitstand-Zugversuch, makroskopische Untersuchungen usw.), um die Gebrauchstauglichkeit von geschweißten Fügeteilen aus thermoplastischen Kunststoffen zu beurteilen.

Essais des assemblages soudés sur produits semi-finis en thermoplastiques - Partie 7: Essai de traction avec éprouvettes entaillées en U

La présente Norme européenne spécifie les dimensions, la méthode d'échantillonnage, la préparation des éprouvettes et les conditions pour effectuer l'essai de traction avec éprouvettes entaillées en U afin de déterminer le facteur de soudage d'énergie de rupture en traction.
Un essai de traction avec éprouvettes entaillées en U peut etre utilisé en combinaison avec d'autres essais (par exemple : essai de pliage, essai de traction, essai de fluage, examen macrographique, ?) pour évaluer les performances des assemblages soudés en matieres thermoplastiques.
Cet essai est applicable a des assemblages soudés dans le meme axe ou le meme plan, composés de matieres thermoplastiques chargées ou non chargées, mais non renforcées, quel que soit le procédé de soudage utilisé. Il n'est pas applicable aux assemblages de tubes de diametre extérieur nominal inférieur a 90 mm.
