Preparation of steel substrates before application of paints and related products - Surface preparation methods - Part 2: Abrasive blast-cleaning (ISO 8504-2:2000)

This part of ISO 8504 describes abrasive blast-cleaning methods for the preparation of steel surfaces before coating with paints and related products. It also contains information on the effectiveness of the individual methods and their fields of application.
ISO 8504 is applicable to new and corroded steel surfaces and to steel surfaces that are uncoated or have been previously coated with paints and related products. For limitations, see note 2.
NOTE 1 These methods are essentially intended for hot-rolled steel to remove mill scale, rust, etc., but could also be used for cold-rolled steel of sufficient thickness to withstand the deformation caused by the impact of abrasive.
NOTE 2 There are several items that should be included in the purchaser's procurement documents to supplement this part of ISO 8504. Items that should be considered as a part of surface preparation before coating are edge grinding, removal of grease and oil, porosity of welds, removal of weld spatter, removal of burrs and other sharp edges, grinding of welds, filling of pits and other surface imperfections that may cause premature failure of the coating system (see ISO 8501-3 for more information) and the removal of water-soluble contaminants.

Vorbereitung von Stahloberflächen vor dem Auftragen von Beschichtungsstoffen - Verfahren für die Oberflächenvorbereitung - Teil 2: Strahlen (ISO 8504-2:2000)

Anwendungsbereich
Dieser Teil von ISO 8504 beschreibt Strahlverfahren für die Vorbereitung von Stahloberflächen vor dem Auftragen von Beschichtungsstoffen. Er enthält auch Angaben über die Wirksamkeit der einzelnen Verfahren und deren Anwendungsbereiche.
ISO 8504 ist auf neue und korrodierte Stahloberflächen anwendbar sowie auf unbeschichtete oder vorher beschichtete Stahloberflächen. Bezüglich Einschränkungen siehe Anmerkung 2.
ANMERKUNG 1   Diese Verfahren sind hauptsächlich bei warmgewalzten Stahl zum Entfernen von Zunder, Rost usw. vorgesehen. Sie können aber auch auf kaltgewalzten Stahl angewendet werden, wenn dieser so dick ist, dass er durch die Einwirkung des Strahlmittels nicht verformt wird.
ANMERKUNG 2   Ergänzend zu diesem Teil von ISO 8504 sollten einige Punkte, die als Teil der Oberflächenvorbereitung vor dem Beschichten betrachtet werden sollten, in die Ausschreibungsunterlagen des Auftraggebers aufgenommen werden: Schleifen von Kanten, Entfernen von Fett und Öl, Porosität von Schweißnähten, Entfernen von Schweißspritzern, Entfernen von Graten und anderen scharfen Kanten, Schleifen von Schweißnähten, Füllen von Poren und andere Oberflächenfehler, welche vorzeitiges Versagen des Beschichtungssystems verursachen können (siehe ISO 8501-3 für weitere Angaben) sowie Entfernen von wasserlöslichen Verunreinigungen.

Préparation des subjectiles d'acier avant application de peintures et de produits assimilés - Méthodes de préparation des subjectiles - Partie 2: Décapage par projection d'abrasif (ISO 8504-2:2000)

La présente partie de l'ISO 8504 prescrit des méthodes de décapage par projection d'abrasif pour la préparation des subjectiles d'acier avant application de peintures et de produits assimilés. Elle contient également des informations sur l'efficacité des différentes méthodes et leurs domaines d'application.
L'lSO 8504 est applicable aux subjectiles d'acier neufs ou corrodés, non revêtus ou précédemment revêtus de peintures ou de produits assimilés. Pour les limites de la méthode, voir également note 2.
NOTE 1 Ces méthodes sont essentiellement destinées aux aciers laminés à chaud, pour éliminer la calamine, la rouille, etc., mais elles peuvent s'appliquer également aux aciers laminés à froid présentant une épaisseur suffisante pour supporter sans déformation l'impact du jet d'abrasif.
NOTE 2 Il convient qu'un certain nombre d'éléments soient inclus dans les documents fournis au client, en complément de la présente partie de l'lSO 8504. Il convient que les éléments suivants soient considérés comme partie intégrante de la préparation des subjectiles avant revêtement: le meulage des aspérités, l'élimination des graisses et huiles, la porosité des soudures, l'élimination des gouttes de soudure, l'élimination des bavures et autres arêtes vives, le meulage des soudures, le bouchage des petits trous et autres imperfections de surface susceptibles de nuire à la tenue du système de revêtement (voir ISO 8501-3 pour plus amples informations) et l'élimination des agents contaminants solubles dans l'eau.
