Microstructure of cast irons - Part 1: Graphite classification by visual analysis (ISO 945-1:2019)

Microstructure of cast irons - Part 1: Graphite classification by visual analysis (ISO 945-1:2019)

This document specifies a method of classifying the microstructure of graphite in cast irons by comparative visual analysis.
The purpose of this document is to provide information about the method of graphite classification. It is not intended to give information on the suitability of cast-iron types and grades for any particular application.
The particular material grades are specified mainly by mechanical properties and, in the case of austenitic and abrasion resistant cast irons, by their chemical composition. The interpretation of graphite form and size does not allow a statistically valid statement on the fulfilment of the requirements specified in the relevant material standard.

Mikrostruktur von Gusseisen - Teil 1: Graphitklassifizierung durch visuelle Auswertung (ISO 945-1:2019)

Dieses Dokument legt ein Verfahren zur Klassifizierung der Mikrostruktur von Graphit in Gusseisen-werkstoffen durch vergleichende visuelle Auswertung fest.
Dieses Dokument bezweckt die Bereitstellung von Informationen zum Verfahren der Graphitklassifi-zierung. Es ist nicht beabsichtigt, Informationen hinsichtlich der Eignung von Gusseisenarten und  sorten für eine bestimmte Anwendung zu geben.
Die speziellen Werkstoffsorten werden hauptsächlich bestimmt durch die mechanischen Eigenschaften und bei austenitischem und verschleißbeständigem Gusseisen durch die chemische Zusammensetzung. Die Bewertung der Graphitform und  größe erlaubt keine statistisch gesicherte Aussage im Hinblick auf die Erfüllung der Anforderungen, die in der jeweiligen Werkstoffnorm festgelegt sind.

Microstructure des fontes - Partie 1: Classification du graphite par analyse visuelle (ISO 945-1:2019)

Le présent document spécifie une méthode de classification de la microstructure du graphite dans les fontes par analyse visuelle comparative.
L'objectif du présent document est d'apporter des informations sur la méthode de classification du graphite. Il n'est pas destiné à donner des informations sur l'aptitude des types et des nuances de fonte, pour une application particulière.
Les nuances particulières des matériaux sont spécifiées principalement par des propriétés mécaniques et, dans le cas des fontes austénitiques et des fontes résistant à l'usure par abrasion, par leur composition chimique. L'interprétation de la forme et de la taille du graphite ne permet pas de prévoir de manière statistiquement valable que les exigences spécifiées dans la norme de matériau concernée seront satisfaites.

Mikrostruktura železove litine - 1. del: Razvrščanje grafita z vizualno analizo (ISO 945-1:2019)

Ta dokument določa metodo razvrščanja mikrostrukture grafita v železovih litinah s primerjalno vizualno analizo.
Namen tega dokumenta je podati informacije o metodi razvrščanja grafita. Ne navaja podatkov o primernosti tipov in razredov železovih litin za nobeno posebno uporabo.
Posamezne razrede snovi določajo predvsem mehanske lastnosti in, če gre za avstenitne in na obrabo odporne litine, njihova kemična sestava. Razlaga grafitne oblike in velikosti ne omogoča statistično veljavne navedbe o izpolnjevanju zahtev, določenih v ustreznem standardu za material.
