Testing of welded joints of thermoplastics semi-finished products - Part 7: Tensile test with waisted test specimens
This document 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 can be used in conjunction with other tests (e.g. bend, tensile, tensile creep, macro, etc.) to assess the performance of welded assemblies, made from thermoplastics materials.
The test is applicable to co-axial or co-planar heated tool butt welded assemblies made from thermoplastics materials filled or unfilled, but not reinforced. It is not applicable to tubular assemblies with a nominal outside diameter less than 90 mm.
Prüfen von Schweißverbindungen an Halbzeugen aus thermoplastischen Kunststoffen - Teil 7: Zugversuch an Probekörpern mit Rundkerbe
Dieses Dokument 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 energiebezogenen Kurzzeitzug-Schweißfaktor zu bestimmen.
Ein Zugversuch an Probekörpern mit Rundkerbe kann 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.
Die Prüfung ist auf koaxiale oder in einer Ebene liegende Heizelementstumpfschweißverbindungen aus thermoplastischen Kunststoffen mit oder ohne Füllstoff, die jedoch nicht verstärkt sind, anwendbar. Die Prüfung ist bei Rohrverbindungen mit einem äußeren Nenndurchmesser kleiner 90 mm nicht anwendbar.
Essais des assemblages soudés sur produits semi-finis en thermoplastiques - Partie 7 : Essai de traction avec éprouvettes entaillées en U
Le présent document 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 être 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 matières thermoplastiques.
Cet essai est applicable à des assemblages soudés au moyen d’un outil chauffé dans le même axe ou le même plan, composés de matières thermoplastiques chargées ou non chargées, mais non renforcées. Il n’est pas applicable aux assemblages de tubes de diamètre extérieur nominal inférieur à 90 mm.
Preskus zvarjenih spojev plastomernih polizdelkov - 7. del: Trgalni preskus z zožanimi preskušanci
Ta dokument določa dimenzije, metodo vzorčenja, pripravo preskušancev in pogoje za izvedbo trgalnega preskusa z zožanimi preskušanci, s katerim se določi natezni faktor zvara.
Trgalni preskus z zožanimi preskušanci je mogoče uporabiti skupaj z drugimi preskusi (npr. preskus upogibanja, natezni preskus, preskus lezenja pri natezni obremenitvi, makro preskus itd.) za oceno zmogljivosti varjenih sestavov iz plastomernih materialov.
Preskus se uporablja za koaksialne ali koplanarne sestave, soležno varjene z ogrevanim orodjem in izdelane iz polnjenih ali nepolnjenih termoplastičnih materialov, ki niso ojačani. Ne uporablja se za cevaste sestave z nazivnim zunanjim premerom, manjšim od 90 mm.
