Testing of welded joints of thermoplastics semi-finished products - Part 8: Requirements
This document provides the requirements for the tests made on welded thermoplastics semi-finished products.
The selection of the appropriate test method(s) should be 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.
Prüfen von Schweißverbindungen aus thermoplastischen Kunststoffen - Teil 8: Anforderungen
In diesem Dokument werden Anforderungen an Prüfungen festgelegt, die an Schweißverbindungen aus thermoplastischen Kunststoffen durchgeführt werden.
Die Wahl des zweckmäßigen Prüfverfahrens sollte entsprechend der jeweiligen Ausführung und Anwendung des geschweißten Produkts getroffen werden.
Die Prüfergebnisse sind von den Herstellbedingungen für die Probekörper und von den Prüfbedingungen abhängig. Sie können deshalb auf das Verhalten der Erzeugnisse oder für die Berechnung einer Konstruktion nur übertragbar sein, wenn die auftretenden Praxisbeanspruchungen den Prüfbedingungen entsprechen.
Essais des assemblages soudés sur produits semi-finis en thermoplastiques - Partie 8 : Exigences
Le présent document définit les exigences pour les essais réalisés sur les produits semi-finis soudés en thermoplastiques.
Il convient de faire le choix de la (des) méthode(s) d’essai appropriée(s) conformément au type particulier et à l’application du produit soudé.
Les résultats des essais dépendent des conditions d’élaboration pour les éprouvettes et des conditions d’essai. Ils peuvent cependant refléter seulement le comportement du produit ou peuvent être utilisés pour concevoir une structure, si les conditions d’essai correspondent aux conditions de service.

European foreword
This document (EN 12814-8:2021) has been prepared by Technical Committee CEN/TC 249 “Plastics”,
the secretariat of which is held by NBN.
This European Standard shall be given the status of a national standard, either by publication of an
identical text or by endorsement, at the latest by July 2021, and conflicting national standards shall be
withdrawn at the latest by July 2021.
