EN 10049:2005

Measurement of roughness average Ra and peak count RPc on metallic flat products

This European Standard defines the measurement conditions for surface roughness parameters of metallic flat products, both uncoated (cold and hot rolled pickled steel) and coated with metallic coatings (e.g. zinc, aluminium, tin, chromium) [see subclause 3.1].

Messung des arithmetischen Mittenrauwertes Ra und der Spitzenzahl RPc an metallischen Flacherzeugnissen

Diese Europäische Norm legt die Prüfbedingungen fest für die Rauheitskenngrößen der Oberflächen von
metallischen Flacherzeugnissen ohne Überzug (kalt- und warmgewalzter gebeizter Stahl) und mit
metallischen Überzügen (z. B. Zink, Aluminium, Zinn, Chrom) [siehe 3.1 ].

Foreword
This European Standard (EN 10049:2005) has been prepared by Technical Committee ECISS/TC 13 “Flat
products for cold working - Qualities, dimensions, tolerances and specific tests”, the secretariat of which is
held by IBN.
This European Standard shall be given the status of a national standard, either by publication of an identical
text or by endorsement, at the latest by May 2006, and conflicting national standards shall be withdrawn at the
latest by May 2006.
The European Committee for Iron and Steel Standardization (ECISS) had charged the Technical Committee
13 (Secretariat Belgium) with preparing a European Standard on the measuring of roughness as a revision of
Euronorm 49.
The reason for the existence of this European Standard is that general roughness measurement rules as
described in ISO standards (see Cl
