(Main)Metallic and other inorganic coatings - Simultaneous thickness and electrode potential determination of individual layers in multilayer nickel deposits (STEP test)
Metallic and other inorganic coatings - Simultaneous thickness and electrode potential determination of individual layers in multilayer nickel deposits (STEP test)
This European Standard applies to the measurement of the thickness of the individual nickel layers in electroplated multilayer nickel coatings and to the measurement of the potential differences between the individual nickel layers in electroplated multilayer nickel coatings.
The measurement of coatings or layer systems other than electroplated multilayer nickel coatings is outside the scope of this European Standard.
Metallische und andere anorganische Überzüge - Schichtpotentialmessung von galvanischen Mehrfach-Nickelschichtsystemen (STEP-Test)
Diese Europäische Norm gilt für die Messung der Schichtdicken der einzelnen Nickelschichten in galvanisch abgeschiedenen Mehrfach Nickelschichtsystemen sowie für die Messung der Potentialdifferenzen zwischen den einzelnen Nickelschichten in galvanisch abgeschiedenen Mehrfach Nickelschichtsystemen.
Die Messung anderer Schichten oder Schichtsysteme als galvanisch abgeschiedene Mehrfach Nickelschicht-systeme gehören nicht zum Anwendungsbereich dieser Europäischen Norm.
Revêtements métalliques et autres revêtements inorganiques - Détermination simultanée de l’épaisseur et du potentiel d’électrode de couches individuelles dans des dépôts de nickel multicouches (essai STEP)
La présente Norme européenne s’applique au mesurage de l’épaisseur des couches de nickel individuelles dans des revêtements électrolytiques de nickel multicouches, ainsi qu’au mesurage des différences de potentiel entre ces couches.
Le mesurage des revêtements ou des systèmes de couches autres que les revêtements électrolytiques de nickel multicouches ne relève pas du domaine d’application de la présente Norme européenne.
Kovinske in druge anorganske prevleke - Istočasno določevanje debeline in potenciala elektrode posameznih plasti v večplastnih nikljevih depozitih (preskus STEP)
Ta standard se uporablja za elektrogalvanske prevleke cinka in cinkovih zlitin na železu ali jeklu s pasivizacijo brez Cr (VI). Prevleke cinka in cinkovih zlitin vsebujejo nikelj ali železo kot legirni sredstvi (imenujejo se cink-nikljeve in cink-železove prevleke). Glavni namen prevlek ali sistemov prevlek je zaščita železnih in jeklenih sestavnih delov pred korozijo. Ta standard predpisuje oznake za uporabo z zgornjimi sistemi prevlek ter določa najmanjšo korozijsko odpornost, ki jo je treba doseči v podanih preskusnih postopkih, in najmanjšo potrebno debelino prevleke.
