Scope and field of application
This part of ISO 8503 specifies the focusing microscope and describes the procedure for calibrating ISO surface profile comparators complying with the requirements of ISO 8563-1.
This part of ISO 8503 is also applicable to the determination of the surface profile, within the range hy = 20 to 200 μm, of essentially planar blast-cleaned steel. The determination may be carried out on a representative section of the blast-cleaned substrate or, if direct observation of the surface is not feasible, on a replica of the surface (see annex E).
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 8503-4.
