3 ● Terms and definitions
For the purposes of this document, the terms and definitions given in EN 1559-1 and of the applicable material standard apply.
4 Information to be supplied by the purchaser
4.1 ● Mandatory information
The relevant wall thickness shall be given in the order.
4.2 Optional information
Where applicable, the enquiry and order shall include other details, such as requirements for a) an as-cast condition;
NOTE Heat treatment of malleable cast irons or ausferritic spheroidal graphite cast irons is a function of the material and is at the discretion of the manufacturer to achieve the desired mechanical properties.
b) special or subsequent heat treatment if required (together with the heat-treatment conditions);
c) heat treatment for stress relieving; it shall be agreed upon between the manufacturer and the purchaser;
d) intentions to enamel, galvanize, plate, etc. the castings;
e) sequence of machining and final heat treatment in the fabrication process (for ausferritic spheroidal graphite iron castings);
f) formation of test units (unless already defined by material specifications it shall be in accordance with 8.3.1).

The designation(s) of cast iron material(s) shall be in accordance with EN 1560.
NOTE Designations of cast iron materials are given in the applicable material standards.
6 Manufacture
6.1 ● Manufacturing process
6.2 Welding operations
6.2.1 ● General
Welding shall be performed by a qualified welder, in accordance with EN 287-6. Welding procedures shall be in accordance with EN ISO 15614-3 and based on the recommendations given in EN 1011-8.
