This part of ISO 8503 specifies the stylus instrument and describes the procedure for calibrating ISO surface profile comparators conforming to the requirements of ISO 8503-1.

This part of ISO 8503 is also applicable to the determination of the surface profile, within the range

\bar{R_{y 5}}

= 20 μm to

\bar{R_{y 5}}

= 200 μm, of essentially planar blast-cleaned steel. 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 (see Annex C).

NOTE Where appropriate, this procedure can be used to assess the roughness profile of other abrasive blast-cleaned substrates.

An alternative procedure is described in ISO 8503-3.
