The technical data are calculated according EN 410, EN 673 and EN 12898.
The above performance data should be considered representative. There may be differences within a single production run or from one production run to another, but these are subject to manufacturing tolerances.
The data presented in this table is related to the as supplied product. Some values, such as sheet resistance, may change after the toughening process depending on toughening conditions.
