Testing of welded joints in thermoplastics semi-finished products - Part 3: Tensile creep test

Testing of welded joints in thermoplastics semi-finished products - Part 3: Tensile creep test

This European Standard specifies the dimensions, the method of sampling and the preparation of the test specimens, and the conditions for performing the tensile creep test perpendicular to the weld in order to determine the long-term tensile welding factor.
A tensile creep test may be used in conjunction with other tests (e.g. bend test, tensile test, macrographic examination,...) 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 such as tubes and fittings, sheets, plates and profiles, but not reinforced, irrespective of the welding process used.

Prüfen von Schweißverbindungen aus thermoplastischen Kunststoffen - Teil 3: Zeitstand-Zugversuch

Diese Europäische Norm legt Maße, Probenahmeverfahren, Probenvorbereitung sowie Durch¬führungs-bedingungen für einen Zeitstand-Zugversuch rechtwinklig zur Schweißnaht fest, bei dem der Zeitstandzug-Schweißfaktor bestimmt wird.
Ein Zeitstand-Zugversuch kann zusammen mit anderen Prüfungen (z. B. Biegeversuch, Zugversuch, makrographische Untersuchung) angewendet werden, um das Betriebsverhalten von Schweißverbindungen aus thermoplastischen Kunststoffen zu beurteilen.
Der Zeitstand-Zugversuch ist auf Schweißverbindungen aus gefüllten oder ungefüllten, jedoch nicht aus verstärkten thermoplastischen Kunststoffen unabhängig vom angewendeten Schweißverfahren anwendbar, z. B. auf Rohre, Fittings, Bahnen und Platten sowie Profile.

Essais des assemblages soudés sur produits semi-finis en thermoplastiques - Partie 3: Essai de fluage en traction

La présente Norme européenne spécifie les dimensions, la méthode d'échantillonnage et la préparation des éprouvettes, ainsi que les conditions d'exécution de l'essai de fluage en traction perpendiculairement à la soudure, afin de déterminer le coefficient de soudure en traction à long terme.
Un essai de fluage en traction peut être utilisé conjointement avec d'autres essais (par exemple : essai de pliage, essai de traction, examen macrographique, ...) pour évaluer les performances des assemblages soudés en thermoplastiques.
Cet essai est applicable aux assemblages soudés constitués de matières thermoplastiques chargées ou non chargées, telles que tubes et raccords, feuilles, plaques et profilés, mais non renforcées, indépendamment du procédé de soudage utilisé.

Preskus zvarjenih spojev plastomernih polizdelkov - 3. del: Preskus lezenja pri natezni obremenitvi

Standard EN 12814-3 določa dimenzije, metodo vzorčenja, pripravo preskusnih vzorcev in pogoje za izvedbo preskusa lezenja pri natezni obremenitvi, pravokotno na zvar, s katerim se določi dolgoročni natezni faktor zvara. Preskus lezenja pri natezni obremenitvi se lahko uporabi skupaj z drugimi preskusi (npr. preskus upogibanja, natezni preskus, makrografski pregled ...) za oceno zmogljivosti varjenih sestavov iz termoplastičnih materialov. Preskus se uporablja za varjene sestave iz polnjenih ali nepolnjenih termoplastičnih materialov, kot so cevi in spojniki, ponjave, plošče, in profili, ki niso ojačani – ne glede na uporabljeni postopek varjenja.

Testing of welded joints of thermoplastics semi-finished products - Part 8: Requirements
SIST EN 12814-8:2021

This document provides the requirements for the tests made on welded thermoplastics semi-finished products.
The selection of the appropriate test method(s) is made in accordance with the particular type and application of welded product.
The test results depend on the conditions of manufacture for the test specimen and on the test conditions. They can therefore only be related to the behaviour of the product or can only be used for designing a structure, if the test conditions can be related to the service conditions.

Imperfections in thermoplastic welds - Classification
SIST EN 14728:2019

This document specifies a system for classifying imperfections that may be encountered in thermoplastic welded joints during manufacture and provides examples of imperfections for the following welding processes:
-   heated tool butt welding;
-   heated tool socket welding;
-   electrofusion socket welding;
-   hot gas welding;
-   extrusion welding;
-   solvent socket welding.
This document does not describe imperfections that may be generated during service or imperfections present before welding, which are due to poor preparation or assembly of components (e.g. fit up). The correct preparation and assembly of components (e.g. fit up) are described in the relevant welding procedure specification (WPS).
This document is also not concerned with the search for the possible influence of these imperfections on the behaviour of joints in relation to the different types of stress to which the latter may be subjected or on methods for preventing such imperfections.
This document can be used in conjunction with EN 16296 [1] to determine the acceptance of welds.
Only imperfections giving rise to discontinuities of materials or changes in shape are taken into consideration in this document, specifying their type, their shape and their positions. This classification can be used to determine the possible origin or causes of the imperfections.
