BS EN ISO 945-1:2019 - TC

This standard BS EN ISO 945-1:2019 - TC Tracked Changes. Microstructure of cast irons is classified in these ICS categories:

• 77.140.80 Iron and steel castings
• 77.080.10 Irons

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.
