Quality requirements for welding - Fusion welding of metallic materials - Part 4: Elementary quality requirements

This standard has been prepared such that:  - it is independent of the type of welded construction to be manufactured; - it defines quality requirements for welding both in workshops and on site; - it provides guidance for describing a manufacturers capability to produce welded constructions to meet specified requirements; - it may also be used as a basis for assessing the manufacturer in respect to his welding capability.  This standard is appropriate when demonstration of a manufacturers capability to produce welded construction, fulfilling specified quality requirements, are specified in one or more of the following:  - a contract between involved parties; - an application standard; - a regulatory requirement.  The requirements contained within this standard may be adopted in full or may be selectively deleted by the manufacturer if not applicable to the construction concerned. They provide a flexible framework for the control of welding in the following cases:  - Case 1  To provide specific requirements for fusion welding in contracts which require the manufacturer to have a quality system other than EN 29001 or EN 29002 and where the documented welding control has a minor importance to the overall integrity of the final construction.  - Case 2  To provide specific requirements for fusion welding as guidance to a manufacturer developing a quality system.  - Case 3  To provide specific requirements for references in application standards which uses fusion welding as part of its requirements or in a contract between relevant parties.

Schweißtechnische Qualitätsanforderungen - Schmelzschweißen metallischer Werkstoffe - Teil 4: Elementar-Qualitätsanforderungen

Diese Norm ist so erstellt worden, dass sie von der Art der zu fertigenden Schweisskonstruktionen unabhängig ist. Diese Norm legt die Anforderungen an ein Elementar-Qualitätssicherungssystem für das Schweissen sowohl in Werkstätten als auch auf Baustellen fest. Sie vermittelt Hinweise zur Beschreibung eines Herstellers über seine Fähigkeit, geschweisste Konstruktionen in vorgeschriebener Qualität anzufertigen. Sie soll auch als Grundlage für die Anerkennung des Qualitätssicherungssystems eines Herstellers fûr das Schweissen verwendet werden.

Exigences de qualité en soudage - Soudage par fusion des matériaux métalliques - Partie 4: Exigences de qualité élémentaire

La présente norme a été élaborée de façon à la rendre indépendante du type de construction soudée dont la fabrication est envisagée.  Cette norme définit les exigences d'un système qualité pour le soudage, applicables aux conditions dans les ateliers et sur les sites.  Elle fournit des orientations pour décrire l'aptitude d'un fabricant à produire des constructions soudées de la qualité stipulée.  Il convient aussi de s'en servir comme basee pour l'évaluation du système qualité mis en oeuvre par un fabricant pour le soudage.
