ISO FDIS 8503-1

Description / Abstract: Scope and field of application

This part of ISO 8503 specifies the requirements for ISO surface profile comparators which are intended for visual and tactile comparison of steel substrates that have been blast-cleaned with either shot abrasives or grit abrasives. ISO surface profile comparators are for use in assessing, on site, the roughness of surfaces before the application of paints and related products or other protective treatments.

NOTE -- Where appropriate, these comparators may be used for assessing the roughness profile of other abrasive blast-cleaned substrates and, in addition, their use is not restricted solely to surfaces that are to be painted.

This part of ISO 8503 also includes definitions of the terms used in this and the other parts of ISO 8503.
