Characteristics of the roughness of blast-cleaned surfaces are defined in 3. BSI also holds the copyright, in the UK, of the publications of the international standardization bodies. For dated references, subsequent amendments 85034 or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision.

Various BSI electronic information services are also available which give details on all its products and services. These surface characteristics are considered to give sufficient distinguishing features for most painting requirements.

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.

Only surface profile comparators that comply may be inscribed on the underside as described in clause 4. Method for the grading of surface profile of abrasive blast-cleaned steel — Comparator procedure Preparation of steel substrates before application of paints and related products — Surface roughness characteristics of blast-cleaned steel substrates — Part 3: The segments shall comply with the values given in Table 1 when measured according to the methods described in ISO or ISO Table 2 — Limits of profile grades a Comparators for steel, blast-cleaned with grit abrasives Fine G Medium G Coarse G Profiles equal to segment 1 and up to but excluding segment 2 Profiles equal to segment 2 and up to but excluding segment 3 Profiles equal to segment 3 and up to but excluding segment 4 6 Calibration of comparators A comparator shall be deemed to have been calibrated if, on measuring each of the profiles on the 85033-4 surface by either the method described in ISO or jso method described in ISOthe values for ido the profiles are within the respective nominal values and tolerances specified in Table 1.

These International Standards do not contain recommendations for the protective coating systems to be applied to the steel surface. Each of these International Standards is in turn divided into separate parts. Need more than one copy? Never place the comparator face down on rough surfaces despite the protection strips. Annex ZA normative Normative references to international publications with their relevant European publications This European Standard incorporates by dated or undated reference, provisions from other publications.

The determination can be carried out on a representative section of the blast-cleaned surface or, if direct observation of the surface is not feasible, on a replica of the surface. Iwo describes the method of using 88503-4 comparators. We have no amendments or corrections for this standard.
