ISO 643, all parts: Steels - Micrographic determination of the apparent grain size4 laboratories in Germany are accredited by DAKKS for at least one part of ISO 643. Each lab card shows which parts it holds. These labs commonly handle Metal matrices. From the accredited scope text: “ISO 643 2020 -06 Stahl – Mikrophotographische Bestimmung der erkennbaren Korngröße DIN EN 10247 2017 -09 Metallographische Prüfung des Gehaltes nichtmetallischer Einschlüsse in Stählen mit Bildreihen” “ISO 643 2013-05 Stahl - Mikrophotographische Bestimmung der erkennbaren Korngröße DIN EN ISO 945 -1 2019-10 Mikrostruktur von Gusseisen - Teil 1: Graphitklassifizierung durch visuelle Auswertung DIN E” “ISO 643 2020-06 Stahl ‒ Mikrophotographische Bestimmung der erkennbaren Korngröße LE5 ASTM E 112 2013 Standard Test Methods for Determining Average Grain Size LE5 DIN 50602 1985-09 Metallographische P”
