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) 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.
Prüfen von Schweißverbindungen aus thermoplastischen Kunststoffen - Teil 8: Anforderungen
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.
Le choix de la (des) méthode(s) d’essai appropriée(s) est fait 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 ne peuvent donc être liés qu'au comportement du produit ou ne peuvent être utilisés pour la conception d'une structure que si les conditions d'essai peuvent être liées aux conditions de service.

1 Scope
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.
