4 Orders or tenders
The order or tender shall define the product required and shall contain the following details:a) the type and form of the product:
1) designation of the magnesium or magnesium alloy;2) form of the product (sheet, plate);
b) the metallurgical temper (degree of hardness or heat treatment condition) of the material for
delivery and, if different, the metallurgical temper for use;
c) the number of this document, i.e. ISO 23700, the specification number, or, where none exists, the
properties agreed between the supplier and the purchaser;
d) the dimensions and shape of the product (thickness, width, length, diameter of the coil);
e)the tolerances of the dimensions and form, with reference to the appropriate clause or subclause of
this document;
f) the quantity;
g) any requirements for certificates of conformity, test and/or analysis;
h) any special requirements agreed between the supplier and the purchaser (e.g. drawings).5Requirements
5.1 Designation
The following symbols shall be used for temper designation:-0: annealed;
– H112: strain hardened from working at elevated temperature or from a limited amount of cold
work, and for which there are mechanical properties limits;
H x4: half hardened (strain hardened to give an ultimate tensile strength approximately midwaybetween that of annealed and H ×8 temper);
―H×2: quarter hardened (strain hardened togive an ultimate tensile strength approximately midway
between that of annealed and H x 4 temper);
— T5: cooled from an elevated temperature shaping process and then artificially aged.The alloy designation and temper should be as given in Table 1.BS ISO 23700 pdf download.
