Scope and field of application

This part of ISO 8503 specifies the stylus instrument and describes the procedure for calibrating ISO surface profile comparators complying with the requirements of ISO 8503-l.

This part of ISO 8503 is also applicable to the determination of the surface profile, within the range qs = 20 to 200 pm, of essentially planar blast-cleaned steel. The determination may 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 (see annex C).

NOTE - Where appropriate, this procedure may be used for assessing the roughness profile of other abrasive blast-cleaned substrates.

An alternative procedure is described in ISO 8503-3.
