Introduction

CEN/TC 190 “Foundry Technology” has prepared a series of material standards covering the following cast irons:

grey cast irons [1];
malleable cast irons [2];
spheroidal graphite cast irons [3];
ausferritic spheroidal graphite cast irons [4];
abrasion resistant cast irons [5];
austenitic cast irons [7];
compacted (vermicular) graphite cast irons [8];
low alloyed ferritic spheroidal graphite cast irons for elevated temperature applications [9].

In order to assist manufacturers and purchasers to prepare proper contractual arrangements and prevent misunderstanding, CEN/TC 190 approved the preparation of a series of standards covering technical delivery conditions. These have been prepared as separate parts.

This document covers the additional technical delivery conditions for all the cast iron materials, e.g. optional information, manufacturing process, welding operation, additional requirements regarding the condition of the casting, test methods.

This document cannot be used alone for compiling a specification for ordering and supplying iron castings, but as a complement to EN 1559‑1.

1 Scope

This document specifies the additional technical delivery conditions for castings made from all cast iron materials.

This document applies to iron castings produced in sand or permanent moulds or by centrifugal casting, continuous casting or investment casting.
