Testing of welded joints of thermoplastics semi-finished products - Part 4: Peel test

Testing of welded joints of thermoplastics semi-finished products - Part 4: Peel test

This document specifies the dimensions, the method of sampling and the preparation of the test specimens, and also the conditions for performing the peel test perpendicular to the weld in order to determine the peel resistance and the failure behaviour.
A peel test can be used in conjunction with other tests (e.g. tensile creep, macroscopic examination...) to assess the performance of welded assemblies, made from thermoplastics materials.
Peel tests are applicable to overlap welded assemblies made from thermoplastics materials.
The T-peel test as defined in Clause 5 will be used only for assessing welded sheet assemblies. This test is not applicable to welded test pieces containing sheets of different nominal thickness.
The decohesion test as defined in Clause 6 will be used only for assessing electrofusion joints with nominal thickness of pipe/fitting greater than 10 mm.
For socket fusion and for electrofusion socket joints with nominal outside diameter less than or equal to 90 mm, a crush test will be used, as defined in Clause 7.
The crush test can also be used for electrofusion joints with outside diameters greater than 90 mm.
The crush test for electrofusion saddle joints will be performed in accordance with ISO 13955 [1].
NOTE   A decohesion test is also defined in ISO 13954 [2].
The tests defined in this standard are not intended to be used for assessment and/or qualification of thermoplastic fittings that already have their own requirements, e.g. polyethylene fittings according to EN 1555-3 [3] and EN 12201-3 [4].

Prüfen von Schweißverbindungen aus thermoplastischen Kunststoffen - Teil 4: Schälversuch

Essai des assemblages soudés sur produits semi-finis en thermoplastiques - Partie 4 : Essai de pelage

Le présent document spécifie les dimensions, la méthode d’échantillonnage et la préparation des éprouvettes, ainsi que les conditions d’exécution de l’essai de pelage perpendiculairement à la soudure pour déterminer la résistance au pelage et le comportement à la rupture.
Un essai de pelage peut être utilisé en combinaison avec d’autres essais (par exemple essai de fluage, examen macroscopique, ...) pour évaluer les performances d’assemblages soudés, réalisés à partir de matières thermoplastiques.
Les essais de pelage sont applicables aux assemblages soudés par recouvrement réalisés à partir de matières thermoplastiques.
L’essai de pelage en T, tel que défini à l’Article 5, doit uniquement être utilisé pour l’évaluation d’assemblages de plaques soudées. Cet essai ne s’applique pas aux pièces d’essai soudées comprenant des plaques d’épaisseurs nominales différentes.
L’essai de décohésion, tel que défini à l’Article 6, doit uniquement être utilisé pour l’évaluation d’assemblages électrosoudables de tube/de raccord ayant une épaisseur nominale supérieure à 10 mm.
Pour les assemblages par fusion d’emboîture et les assemblages par emboîture électrosoudable ayant un diamètre extérieur nominal inférieur ou égal à 90 mm, un essai d’écrasement, tel que défini à l’Article 7, doit être effectué.
L’essai d’écrasement peut également être effectué pour les assemblages électrosoudables ayant un diamètre extérieur supérieur à 90 mm.
L’essai d’écrasement pour les assemblages avec selles de branchement électrosoudables doit être effectué conformément à l’ISO 13955 [1].
NOTE      Un essai de décohésion est également défini dans l’ISO 13954 [2].
Les essais définis dans la présente norme ne sont pas destinés à être utilisés pour l’évaluation et/ou la qualification de raccords en matières thermoplastiques qui sont déjà soumis à des exigences spécifiques, par exemple raccords en polyéthylène conformes à l’EN 1555-3[3] et à l’EN 12201-3[4].

Testing of welded joints of thermoplastics semi-finished products - Part 7: Tensile test with waisted test specimens
EN 12814-7:2024

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.

Testing of welded joints of thermoplastics semi-finished products - Part 8: Requirements
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) 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.

Imperfections in thermoplastic welds - Classification
EN 14728:2019

This draft European Standard 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 either during service or present before welding such as poor fit up. The correct preparation (e.g. fit up) is 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 cannot therefore be used to determine the acceptance of welds, which is defined in EN 16296 [1].
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.

Testing of welded joints of thermoplastics semi-finished products - Part 4: Peel test
EN 12814-4:2018

This draft European Standard specifies the dimensions, the method of sampling and the preparation of the test specimens, and also the conditions for performing the peel test perpendicular to the weld in order to determine the peel resistance and the failure behaviour.
A peel test may be used in conjunction with other tests (e.g. tensile creep, macroscopic examination...) to assess the performance of welded assemblies, made from thermoplastics materials.
Peel tests are applicable to overlap welded assemblies made from thermoplastics materials.
The T-peel test as defined in Clause 5 will be used only for assessing welded sheet assemblies. This test is not applicable to welded test pieces containing sheets of different nominal thickness.
The decohesion test as defined in Clause 6 will be used only for assessing electrofusion joints with nominal thickness of pipe/fitting greater than 10 mm.
For socket fusion and for electrofusion socket joints with nominal outside diameter less than or equal to 90 mm, a crush test will be used, as defined in Clause 7.
The crush test can also be used for electrofusion joints with outside diameters greater than 90 mm.
The crush test for electrofusion saddle joints will be performed in accordance with ISO 13955 [6].
NOTE   A decohesion test is also defined in ISO 13954 [5].
The tests defined in this standard should not be used for assessment and/or qualification of thermoplastics fittings, e.g. polyethylene fittings according to EN 1555-3 [1] and EN 12201-3 [2], because they already have their own requirements.
