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 = 20 μm to = 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.
