It also contains information on features that are taken into account when selecting and specifying certain surface preparation methods and preparation grades. 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. This document describes methods for hand-tool and power-tool cleaning of steel substrates before application of paints and related products.

It is applicable both to new steelwork and to steel surfaces that have been coated previously and that show areas of breakdown requiring maintenance painting. It describes the equipment to be used and the procedures to be followed. This document specifies a test method for the determination of the level of free moisture present in metallic blast-cleaning abrasives. It is determined by measuring the mass lost on heating.

This is one of a number of parts of ISO dealing with the sampling and testing of metallic abrasives for blast-cleaning. The types of metallic abrasive and requirements for each are contained in the various parts of ISO This document specifies a method for the sampling of metallic blast-cleaning abrasives from consignments and for the subdivision of the sample into quantities suitable for undertaking the appropriate test methods specified in other parts of ISO The ISO This document specifies requirements for nickel slag abrasives, as supplied for blast-cleaning processes.

It specifies ranges of particle sizes and values for apparent density, Mohs hardness, moisture content, conductivity of aqueous extract and water-soluble chlorides. The requirements specified in this document apply to abrasives supplied in the "new" condition only.

They do not apply to abrasives either during or after use. Test methods for non-metallic blast-cleaning abrasives are given in This document specifies requirements for 14 grades of high-carbon cast-steel shot and 11 grades of high-carbon cast-steel grit, as supplied for blast-cleaning processes.

Test methods for metallic blast-cleaning abrasives are given in the This document specifies requirements for iron and steel slag abrasives, as supplied for blast-cleaning processes. Test methods for non-metallic blast-cleaning abrasives are This document specifies requirements for fused aluminium oxide abrasives, as supplied for blast-cleaning processes.

It specifies ranges of particle sizes and values for apparent density, bulk density, Mohs hardness, moisture content, conductivity of aqueous extract and water-soluble chlorides.

This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by August , and conflicting national standards shall be withdrawn at the latest by August Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights.

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. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting.

ISO shall not be held responsible for identifying any or all such patent rights. The principal factors that are known to influence this performance are: a the presence of rust and mill scale; b the presence of surface contaminants, including salts, dust, oils and greases; c the surface profile.

International Standards ISO all parts , ISO all parts and ISO all parts have been prepared to provide methods of assessing these factors, while ISO all parts provides guidance on the preparation methods which are available for cleaning steel substrates, indicating the capabilities of each in attaining specified levels of cleanliness.

These International Standards do not contain provisions for the protective coating systems to be applied to the steel surface, nor for the surface quality provisions for specific situations even though surface quality can have a direct influence on the choice of protective coating to be applied and on its performance.

Such provisions are found in other documents, such as national standards and codes of practice. It is necessary for the users of these International Standards to ensure that the qualities specified are: — compatible and appropriate both for the environmental conditions to which the steel is exposed and for the protective coating system to be used; — within the capability of the cleaning procedure specified. The four International Standards referred to above deal with the following aspects of preparation of steel substrates: — ISO Visual assessment of surface cleanliness; — ISO Tests for the assessment of surface cleanliness; — ISO Surface roughness characteristics of blast-cleaned steel substrates; — ISO Surface preparation methods.

The method can be used by any laboratory equipped with a good microscope which has a calibrated focusing mechanism meeting the requirements of 5.

This procedure can also be used to determine the profile of a substrate after abrasive blast-cleaning either directly or from a replica. This method has the disadvantage of requiring a series of tedious measurements, but good precision and agreement between laboratories and between operators can be obtained by specifying closely the field of view and depth of field of the microscope.
