This European Standard was approved by CEN on 24 February 2020.

CEN members are bound to comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this
European Standard the status of a national standard without any alteration. Up-to-date lists and bibliographical references
concerning such national standards may be obtained on application to the CEN-CENELEC Management Centre or to any CEN
member.
This European Standard exists in three official versions (English, French, German). A version in any other language made by
translation under the responsibility of a CEN member into its own language and notified to the CEN-CENELEC Management
Centre has the same status as the official versions.

• for the general case, see EN 4259;
• for heat treatment using a continuous furnace, a continuous run of less than or equal to eight h may
be considered as the same heat treatment charge.
4 Wording of order
The order shall clearly indicate:
a) quantities to be supplied;
b) dates of delivery;
c) material standard number;
d) delivery condition and metallurgical code of products;
e) dimensions and tolerances or reference to an appropriate dimensional standard;
f) product designation, when required;
g) forwarding address;
h) nature and type of packing, if required;
i) surface protection, if appropriate;
j) definition and frequency of any special tests and their retest procedures, if required.
