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].

Die Quetschprüfung kann auch für Heizwendelschweißverbindungen mit Rohraußendurchmessern von über 90 mm angewendet werden.
Die Quetschprüfung für Heizwendel Falzverbindungen ist nach ISO 13955 [6] durchzuführen.
ANMERKUNG 1 Eine Schältrennprüfung ist auch in ISO 13954 [5] definiert.
Die in dieser Norm definierten Prüfungen sollten nicht für die Bewertung und/oder Qualifizierung von Thermoplast Formstücken, z. B. Polyethylen Formstücken nach EN 1555 3[1] und EN 12201 3[2] angewendet werden, da hierfür eigene Anforderungen gelten.

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].
Preskus zvarjenih spojev plastomernih polizdelkov - 4. del: Preskus luščenja
Ta osnutek evropskega standarda določa dimenzije, metodo vzorčenja, pripravo preskusnih vzorcev in tudi pogoje za izvedbo preskusa luščenja pravokotno na zvar, s katerim se določi odpornost na luščenje in vedenje ob okvarah.
Preskus luščenja se lahko uporabi skupaj z drugimi preskusi (npr. lezenje pri natezni obremenitvi, makroskopski pregled itd.) za oceno zmogljivosti varjenih sestavov iz plastomernih materialov.
Preskusi luščenja se uporabljajo za prekrivno zvarjene sestave, izdelane iz plastomernih materialov.
Preskus luščenja T, kot je določen v točki 5, se uporablja le za ocenjevanje sestavov varjenih plošč. Ta preskus se ne uporablja za varjene preskušance, ki vsebujejo plošče različne nazivne debeline.
Dekohezijski preskus, kot je določen v točki 6, se uporablja samo za ocenjevanje elektrofuzijskih spojev z nazivno debelino cevi/fitinga, večjo od 10 mm.
Pri varilnih in elektrofuzijskih spojih z nazivnim zunanjim premerom, manjšim ali enakim 90 mm, se uporablja preskus drobljenja, kot je določen v točki 7.
Preskus drobljenja se lahko uporablja tudi za elektrofuzijske spoje z zunanjimi premeri, večjimi od 90 mm.
Preskus drobljenja za elektrofuzijske sedlaste spoje bo izveden skladno s standardom ISO 13955 [6].
OPOMBA: Dekohezijski preskus je določen tudi v standardu ISO 13954 [5].
Preskusi, določeni v tem standardu, se ne smejo uporabljati za ocenjevanje in/ali kvalifikacijo plastomernih fitingov, npr. polietilenskih fitingov skladno s standardoma EN 1555-3 [1] in EN 12201-3 [2], ker že vključujejo lastne zahteve.

The article discusses the specifications and procedures for conducting a peel test on welded joints of thermoplastics semi-finished products. The peel test is used to determine the peel resistance and failure behavior of the weld. It can be used alongside other tests to assess the performance of welded assemblies made from thermoplastics. The T-peel test is specifically used for welded sheet assemblies, while the decohesion test is used for electrofusion joints with a pipe/fitting thickness greater than 10mm. The crush test is used for socket fusion and electrofusion socket joints with a nominal outside diameter less than or equal to 90mm. It can also be used for electrofusion joints with an outside diameter greater than 90mm. However, these tests should not be used for assessing thermoplastic fittings that already have their own specific requirements.
The article discusses the EN 12814-4:2018 standard, which focuses on testing welded joints of thermoplastics semi-finished products using the peel test. It specifies the dimensions, sampling method, and test specimen preparation. The peel test is used to determine the peel resistance and failure behavior of thermoplastic welded assemblies. This test can be used alongside other tests to evaluate the performance of welded assemblies made from thermoplastics. Different types of tests, such as the T-peel test, decohesion test, and crush test, are specified depending on the type and thickness of the welded material. It is important to note that these tests are not intended for assessing or qualifying thermoplastic fittings that already have their own specific requirements.
