Preparation of steel substrates before application of paints and related products - Surface preparation methods - Part 2: Abrasive blast-cleaning (ISO 8504-2:2019)

This document specifies abrasive blast-cleaning methods for the preparation of steel surfaces before coating with paints and related products. It provides information on the effectiveness of the individual methods and their fields of application. It describes the equipment to use and the procedure to follow.
NOTE    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.

Vorbereitung von Stahloberflächen vor dem Auftragen von Beschichtungsstoffen - Verfahren für die Oberflächenvorbereitung - Teil 2: Strahlen (ISO 8504-2:2019)

Dieses Dokument legt Strahlverfahren für die Vorbereitung von Stahloberflächen vor dem Auftragen von Beschichtungsstoffen fest. Es enthält Angaben über die Wirksamkeit der einzelnen Verfahren und deren Anwendungsbereiche. Es beschreibt die zu verwendenden Werkzeuge und wie man sie benutzen muss.
ANMERKUNG Diese Verfahren sind hauptsächlich für 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.

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 8504-2:2019)

Le présent document spécifie des méthodes de décapage par projection d'abrasif pour la préparation des subjectiles d'acier avant application de peintures et de produits assimilés. Il fournit des informations sur l'efficacité des différentes méthodes et leurs domaines d'application. Il décrit l'appareillage à utiliser et le mode opératoire à suivre.
NOTE       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.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
