Material standard line reference Requirements Frequency of testing Qualification Release No. Title 4.2 Method of production Mechanical hot working: The manufacturer shall establish a procedure for mechanical hot working. This procedure shall define:  the homogenisation thermal cycle;  the thermo-mechanical working processes;  the manufacturing schedule for each process: the temperatures and durations of pre-heating; the temperature range for each working process; the dimensions of the products at each step and conditions for heat treatment between operations. Mechanical cold working: The manufacturer shall establish a procedure for the mechanical cold working. This procedure shall define:  the mechanical working processes;  the manufacturing schedule for each process; the dimensions of the products at each step and heat treatment conditions between operations. Final operation: Straightening and stress relieving operations shall be indicated in the manufacturing schedule and shall not cause any imperfection prejudicial to the intended use. Surface finishing: Unless otherwise specified, products shall be supplied in the condition specified in the material standard. − − 4.3 Limit dimension(s) Minimum and/or maximum size of the product expressed as nominal thickness, a, or nominal thicknesses for multi-legged/flanged sections, or as a nominal diameter, D, of round bar or as equivalent diameter De. − − 5 Technical specification Reference to this technical specification EN 4700-002. In cases of conflict, the requirements of the material standard shall take precedence over those of this technical specification. − −
Marking: The method of marking used shall not cause corrosion, crack initiation, contamination or unacceptable deformation. The marking shall remain permanently visible after handling and contact with protective products. Unless otherwise specified, the nature and colour of marking ink and type of marking characters shall be left to the discretion of the manufacturer. The marking inks shall be removable with cleaning products which do not leave a residue which could affect further processing. The cleaning products shall not give rise to corrosion. All bars shall be marked legibly in a position chosen by the manufacturer as indicated in the following tables unless otherwise agreed between the manufacturer and customer:
Products
Continuous marking a
or end marking b
• Material grade • heat number
Fabrication lot number • Delivery condition • Manufacturer/identification
a Ink or similar product shall be used.
b Hard stamping on one end of the bar.
For small cross sections, there is a third option:
Products of diameter or major sectional dimension, a or D < 35 mm
• The information stated in the above table shall be indelibly marked on a durable label attached to each bundle or
