The quality levels given in this standard are intended to provide basic reference data and are not specifically related to any particular application. They refer to the types of welded joints in a fabrication and not to the complete product or component itself. It is possible, therefore, that different quality levels are applied to individual welded joints in the same product or component. The choice of quality level for any application should take account of design considerations, subsequent processing, mode of stressing (e.g. static, dynamic), service conditions (e.g. pressure, temperature, environment) and consequences of failure. Economic factors are also important and should include not only the cost of welding but also of inspection, test and repair. Although this European Standard includes types of imperfections relevant to the processes given in Clause 1, only those which are applicable to the process and application in question need to be considered. Imperfections are quoted in terms of their actual dimensions. However their detection and evaluation may require the use of one or more methods of non-destructive testing. It should be noted that the detection and sizing of imperfections is dependent on the inspection methods and the extent of testing specified in the application standard or contract. The need for detection is not the subject of this standard. This European Standard is directly applicable to visual examination of welds or test specimens. It does not include details of recommended methods of detection and sizing. The indication provided by non-destructive testing should not be used directly for the evaluation of quality levels. Therefore, it needs to be supplemented by requirements for examinations, inspection and testing.

The purpose of this standard is to define quality levels based on typical imperfections, which might occur in normal fabrications and are classified in EN 14728. It may be used within a quality system for the production of factory welded joints. It provides three sets of dimensional values from which a selection can be made for a particular application. The quality level necessary in each case should be defined by the application standard or the fabricator in conjunction with the user and/or other parties concerned. The level should be prescribed before the start of production, preferably at the enquiry or order stage. For specific applications, additional requirements not covered by this standard may need to be prescribed. These additional requirements shall be defined as quality level A. SIST EN 16296:2014

Diese Qualitätslevels bieten den Herstellern die Flexibilität, je nach spezifischen Anforderungen und Einsatzgebieten zu wählen, was die Norm besonders relevant macht. Darüber hinaus listet die Norm eine Vielzahl von verwendbaren Thermoplasten, darunter ABS, ECTFE, FEP, PB, PE, PFA, PP-B, PP-H, PP-R, PVC-C, PVC-U und PVDF. Diese umfassende Materialabdeckung zeigt die Vielseitigkeit der Norm und ermöglicht konkrete Anwendung für unterschiedliche Sektoranforderungen. Des Weiteren behandelt die Norm die Anwendung verschiedener Schweißprozesse, einschließlich Heißwerkzeugschweißen, Elektrofusionsschweißen, Heißgasschweißen unter Verwendung eines Füllstifts, Extrusionsschweißen und das Lösemittelverkleben von Rohren. Diese umfangreiche Betrachtung der Schweißtechniken überträgt die Relevanz der Norm auf unterschiedliche industrielle Anwendungen. Insgesamt ist die EN 16296:2012 eine essenzielle Norm, die die Qualität von geschweißten Thermoplastverbindungen regelt und somit einen wertvollen Beitrag zur Verbesserung der Produktsicherheit und -zuverlässigkeit in der Industrie leistet.
La norme EN 16296:2012, intitulée "Imperfections in thermoplastics welded joints - Quality levels", est un document essentiel dans le domaine de la production et de la fabrication de joints soudés en thermoplastiques. Son champ d'application couvre des matériaux d'une épaisseur supérieure à 2,0 mm, ce qui la rend particulièrement pertinente pour des secteurs industrialisés nécessitant des exigences élevées en matière de qualité. L'un des principaux atouts de cette norme réside dans la définition de trois niveaux de qualité pour les imperfections des joints soudés, identifiés par les symboles B, C et D. Ce système hiérarchique permet une large gamme d'applications pour les fabrications soudées. Le niveau B, étant le plus strict, garantit une production conforme aux normes les plus exigeantes, assurant ainsi une durabilité et une performance accrues des produits fabriqués. La norme s'applique à une variété de matériaux thermoplastiques, tels que l’ABS, l'ECTFE, le FEP, le PB, le PE, le PFA, le PP-B, le PP-H, le PP-R, le PVC-C, le PVC-U, et le PVDF. Cette diversifié de matériaux offre une flexibilité dans leur utilisation, pouvant répondre à des besoins spécifiques selon les processus de soudage. En intégrant des procédés tels que le soudage à l'outil chauffé, le soudage par électrofusion, et le soudage à gaz chaud, la norme garantit que les fabricants peuvent choisir la méthode la plus appropriée en fonction de la nature de leur projet. L'importance de cette norme réside également dans le fait qu'elle se concentre sur la qualité de production et non sur la conformité à l'usage de l'objet fabriqué, ce qui permet aux utilisateurs de mieux maîtriser les résultats finaux. En garantissant des niveaux clairs pour les imperfections, EN 16296:2012 aide à minimiser les risques et à améliorer la confiance dans les joints soudés en thermoplastiques. En résumé, la norme EN 16296:2012 constitue un instrument incontournable pour les fabricants travaillant avec des matériaux thermoplastiques, leur permettant d'assurer des normes de qualité élevées tout en s'adaptant à un large éventail d'applications et de procédés de soudage.
The EN 16296:2012 standard provides a comprehensive framework for assessing the quality of imperfections in thermoplastics welded joints, specifically targeting materials with a thickness greater than 2.0 mm. This European Standard is pivotal in establishing uniformity in quality evaluation across various applications of welded fabrication, making it easier for organizations within the industry to adhere to consistent quality criteria. One of the strengths of this standard is its categorization of quality levels into three distinct symbols: B, C, and D. By defining B as the most stringent, the standard allows for a clear understanding of the permissible quality levels for different applications. This structured approach facilitates the identification of acceptable imperfections while ensuring that production quality is front and center, without overriding the fitness-for-purpose requirements. Consequently, manufacturers can select the appropriate quality level based on their specific operational needs and requirements. Additionally, EN 16296:2012 encompasses a wide range of thermoplastic materials including, but not limited to, ABS, PE, PVC-U, and PVDF. This extensive scope enhances its relevance across various sectors, providing guidelines applicable to multiple welding processes such as heated tool welding and electrofusion welding. This versatility ensures that the standard can cater to diverse production techniques and materials, promoting wider adoption and compliance. Overall, the EN 16296:2012 standard stands out for its methodical approach to quality assessment in thermoplastic welded joints. By providing clear quality levels and encompassing a broad spectrum of materials and welding processes, it offers significant value to manufacturers seeking to maintain high-quality standards in their welded products.
