Préparation des subjectiles d'acier avant application de peintures et de produits assimilés - Spécifications pour abrasifs métalliques destinés à la préparation par projection - Partie 3: Grenaille ronde et angulaire en acier moulé à haut carbone (ISO 11124-3:1993)
La présente partie de l'ISO 11124 prescrit des exigences pour 14 granulométries d'abrasifs en grenaille ronde en acier coulé à haut carbone et 12 granulométries d'abrasifs en grenaille angulaire en acier coulé à haut carbone, telles qu'elles sont fournies pour la préparation par projection. Des valeurs sont spécifiées pour la dureté, la masse volumique, les exigences relatives aux défauts structuraux et la composition chimique. Les spécifications prescrites dans la présente partie de l'ISO 11124 s'appliquent seulement aux abrasifs fournis à l'état neuf. Elles ne s'appliquent pas aux abrasifs pendant ou après utilisation. Les méthodes d'essai relatives aux abrasifs métalliques destinés à la préparation par projection sont indiquées dans les différentes parties de l'ISO 11125. Les abrasifs en grenaille ronde et angulaire en acier coulé à haut carbone sont utilisés à la fois avec les équipements de sablage en atelier et sur site. Ils sont le plus souvent choisis lorsqu'il existe un système de récupération et de réutilisation de l'abrasif.
NOTES 1 Les annexes A et B donnent des informations sur les normes nationales généralement consultables portant sur les abrasifs métalliques, en relation avec l'ISO 11124. 2 Quoique la présente partie de l'ISO 11124 ait été spécialement établie pour satisfaire aux exigences de préparation des ouvrages en acier, les propriétés prescrites seront généralement approp 384riées pour l'emploi en préparation de subjectiles ou éléments d'autres matériaux, par les techniques de décapage par projection. Ces techniques sont décrites dans l'ISO 8504-2:1992, 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 11124=3:1993(E) 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, governmental and non-governmental, in liaison with ISO, also take patt in the work. ISO collaborates closely with the International Electrotechnical Commission (1 EC) on all matters of electrotechnical standardization. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an lnternational Standard requires approval by at least 75 % of the member bodies casting a vote. International Standard ISO 11124-3 was prepared by Technical Committee lSO/TC 35, Paints and varnishes, Subcommittee SC 12, Preparation of steel Substrates before application of paints and related products. ISO 11124 consists of the following Parts, under the general title Prep- aration of steel Substrates before application of paints and related products - Specifications for metallic blast-cleaning abrasives: - Part 1: General introduction and classifica tion - Part 2: Chilled-iron grit - Part 3: High-carbon cast-steel shot and grit - Part 4: Low-carbon cast-steel shot - Part 5: Cut steel wire At the time of publication of this part of ISO 11124, part 5 was in course of preparation.

INTERNATIONAL STANDARD 0 ISO ISO 11124=3:1993(E) Preparation of steel Substrates before application of paints and related products - Specifications for metallic blast-cleaning abrasives - Part 3: High-carbon cast-steel shot and grit WARNING - Equipment, materials and abrasives used for surface preparation tan be hazardous if used carelessly. Many national regulations exist for those materials and abrasives that are considered to be hazardous during or after use (waste management), such as free silica or carcinogenic or toxic substances. These regulations are therefore to be observed. lt is important to ensure that adequate instructions are given and that all required precautions are exercised. 1 Scope This patt of ISO 11124 specifies requirements for 14 grades of high-carbon cast-steel shot and 12 grades of high-carbon cast-steel grit, as supplied for blast- cleaning processes. Values are specified for hardness, density, defect/structural requirements and Chemical composition. The requirements specified in this part of ISO 11124 apply to abrasives supplied in the “new” condition only. They do not apply to abrasives either during or after use. Test methods for metallic blast-cleaning abrasives are given in the various Parts of ISO 11125. High-carbon cast-steel shot and grit are used in both static and site blasting equipment. They are most of- ten selected where a facility exists for the recovery and re-use of the abrasive. NOTES 1 Information on commonly referenced national Standards for metallic abrasives and their approximate relationship with ISO 11124 is given in annexes A and B. 2 Although this part of ISO 11124 has been developed specifically to meet requirements for preparation of steelwork, the properties specified will generally be appro- priate for use when preparing other material surfaces, or components, using blast-cleaning techniques. These tech- niques are described in ISO 8504-2:1992, Reparation of steel Substrates before application of pain ts and related products - Surface preparation methods - Part 2: Abras- ive blas t-cleaning. 2 Normative references The following Standards contain provisions which, through reference in this text, constitute provisions of this part of ISO 11124. At the time of publication, the editions indicated were valid. All Standards are subject to revision, and Parties to agreements based on this part cf ISO 11124 are encouraged to investi- gate the possibility of applying the most recent edi- tions of the Standards indicated below.
