Preparation of steel substrates before application of paints and related products - Surface roughness characteristics of blast-cleaned steel substrates - Part 4: Method for the calibration of ISO surface profile comparators and for the determination of surface profile - Stylus instrument procedure (ISO 8503-4:1988)

Based on the measurement of the peaks and valleys by vertical displacement of a stylus traversing the test surface in the direction of travel over the specified traversing length. Determination of the mean maximum peak-to-valley height. Repetition of the procedure to obtain values on not less than ten different locations, followed by the calculation of the grand mean value. The procedure is also applicable to the determination of the surface profile of essentially planar blast-cleaned steel.

1.1 La présente partie de l'ISO 8503 décrit l'appareil à palpeur et la méthode pour étalonner les échantillons de comparaison viso-tactile ISO répondant aux exigences de l'ISO 8503-1. 1.2 La présente partie de l'ISO 8503 est également applicable à la détermination d'un profil de surface Ry5, dans la gamme de 20 à 200 µm, d'une surface essentiellement plane décapée par projection d'abrasif. La détermination peut être effectuée sur une partie représentative de la surface préparée ou, si l'observation directe n'est pas possible, sur une réplique (voir annexe C).
NOTE -- Dans certains cas, ce mode opératoire peut convenir pour évaluer le profil de rugosité d'autres subjectiles décapés par projection d'abrasif. Une autre méthode est décrite dans l'ISO 8503-3.

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 8503-4 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.
