Preparation of steel substrates before application of paints and related products - Surface roughness characteristics of blast-cleaned steel substrates - Part 1: Specifications and definitions for ISO surface profile comparators for the assessment of abrasive blast-cleaned surfaces (ISO 8503-1:1988)
Specifies the requirements for ISO surface profile comparators which are intended for visual and tactile comparison of steel substrates. The document also includes definitions of the terms used for surface roughness characteristics. Comparators are for use on site prior to the application of coating materials or protective paintings of surfaces.

Dieser Teil von ISO 8503 legt die Anforderungen an ISO-Rauheitsvergleichsmuster für den Sicht- und Tastvergleich von Stahloberflächen fest, die mit kugeligen oder kantigen Strahlmitteln gestrahlt worden sind. ISO-Rauheitsvergleichsmuster werden vor Ort benutzt, wenn die Rauheit vor dem Auftragen von Beschichtungs- stoffen oder vor anderen schützenden Behandlungen beurteilt werden soll.

La présente partie de l'ISO 8503 spécifie les caractéristiques des échantillons de comparaison viso-tactile ISO, en vue de comparer par la vue et par le toucher les subjectiles d'acier qui ont été préparés par projection d'abrasif à grains nodulaires ou à grains irréguliers. Les échantillons de comparaison viso-tactile ISO sont utilisés pour l'examen, in situ, de la rugosité des surfaces avant l'application de peintures ou de produits assimilés, ou d'autres traitements de protection.
NOTE -- Si besoin est, ces échantillons peuvent être utilisés pour examiner le profil de rugosité d'autres subjectiles préparés par projection d'abrasif et, de plus, leur utilisation n'est pas restreinte aux seules surfaces à peindre. La présente partie de l'ISO 8503 contient également des définitions des termes utilisés dans cette partie et dans les autres parties de l'ISO 8503.

Foreword
IS0 (the International Organization for Standardization) is a worldwide federation of
national standards bodies (IS0 member bodies). The work of preparing International
Standards is normally carried out through IS0 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, 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 IS0 Council. They are approved in accordance with IS0 procedures requiring at
least 75 % approval by the member bodies voting.
International Standard IS0 8503-I was prepared by Technical Committee ISO/TC 35,
Paints 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.
