Testing of welded joints of thermoplastics semi-finished products - Part 2: Tensile test
This document specifies the dimensions, the method of sampling, the preparation of the test specimens and the conditions for performing the tensile test in order to determine the short term tensile welding factor.
A tensile test may be used in conjunction with other tests (e.g. bend, tensile creep, macro) to assess the performance of welded assemblies, made from thermoplastics materials.
The test is applicable to welded assemblies made from thermoplastics materials filled or unfilled, but not reinforced, irrespective of the welding process used.
Prüfen von Schweißverbindungen aus thermoplastischen Kunststoffen - Teil 2: Zugversuch
Dieses Dokument legt Maße, Probenahmeverfahren und Vorbereitung der Proben sowie die Durchführungsbestimmungen für den Zugversuch fest, um den Kurzzeitzug Schweißfaktor zu bestimmen.
Ein Zugversuch darf in Verbindung mit anderen Prüfungen (z. B. Biegeversuch, Zeitstand Zugversuch, makroskopische Prüfung) angewendet werden, um das Betriebsverhalten von Schweißverbindungen aus thermoplastischen Kunststoffen zu beurteilen.
Der Zugversuch ist unabhängig vom angewendeten Schweißverfahren auf Schweißverbindungen anwendbar, die aus gefüllten oder ungefüllten, nicht aber aus verstärkten thermoplastischen Kunststoffen bestehen.
Essais des assemblages soudés sur produits semi-finis en thermoplastiques - Partie 2 : Essai de traction
Le présent document spécifie les dimensions, la méthode d'échantillonnage et la préparation des éprouvettes, ainsi que les conditions pour effectuer l'essai de traction afin de déterminer le facteur de soudage à court terme en traction.
Un essai de traction peut être utilisé en combinaison avec d'autres essais (par exemple : essai de pliage, essai de fluage, examen macrographique, etc.) pour évaluer les performances des assemblages soudés en matières thermoplastiques.
Cet essai est applicable à des assemblages soudés composés de matières thermoplastiques chargées ou non chargées, mais non renforcées, quel que soit le procédé de soudage utilisé.
