Preparation of steel substrates before application of paints and related products - Surface roughness characteristics of blast-cleaned steel substrates - Part 2: Method for the grading of surface profile of abrasive blast-cleaned steel - Comparator procedure (ISO 8503-2:1988)

Describes a visual and tactile method for assessing the grade of the profile. Their use is not solely restricted to surfaces that are prepared to be painted. Comparison of the surface profile of the test surface with the profile of each of the segments of a calibrated ISO surface profile comparator. Identification of the two segments between the profiles of which the test surface lies. the method is applicable to steel surfaces that have been blast-cleaned by use of either shot abrasives or grit abrasives.

Dieser Teil von ISO 8503 beschreibt ein Verfahren für den Sicht- und Tastvergleich zur Feststellung des Grades der Rauheit, die durch eines der in ISO 8504-2 beschriebenen Strahlverfahren entstanden ist. Nach dem Verfahren werden ISO-Rauheitsvergleichsmuster benutzt, mit denen der Rauheitsgrad vor Ort geprüft werden kann, bevor Beschichtungsstoffe aufgebracht oder andere Schutzmaßnahmen durchgeführt werden.

1.1 La présente partie de l'ISO 8503 décrit une méthode visuelle et tactile pour évaluer un profil de surface préparée par une des méthodes par projection d'abrasif comme décrit dans l'ISO 8504-2. La méthode prévoit l'utilisation d'échantillons de comparaison viso-tactile ISO pour évaluer, in situ, la rugosité des surfaces avant l'application de peintures ou d'autres traitements de protection. 1.2 La méthode est applicable aux subjectiles d'acier décapés par projection d'abrasif à grains nodulaires ou à grains irréguliers, mais elle ne s'applique qu'aux surfaces présentant un degré de soins Sa 2 1/2 et Sa 3 selon l'ISO 8501-1 lorsque toute la surface soumise à l'essai donne l'impression d'avoir été entièrement décapée. Elle est applicable à des surfaces décapées par l'action d'abrasifs soit métalliques soit non métalliques.

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. Esch 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, govern-
mental and non-governmental, in liaison with ISO, also take part in the work.
Draft International Standards adopted by the technical committees are circulated to
the member bodies for approval before their acceptance as International Standards by
the ISO Council. They are approved in accordance with ISO procedures requiring at
least 75 % approval by the member bodies voting.
International Standard ISO 8503-2 was prepared by Technical Committee ISO/TC 35,
Pain ts and varnishes.
Users should note that all International Standards undergo revision from time to time
and that any reference made herein to any other International Standard implies its
latest edition, unless otherwise stated.
