Unless otherwise agreed, the value of A must be used. Elongation at an initial measurement length of 5.65 is A so (and so the initial cross-section) the sample is), and is specified as a percentage. For certain products, the supplier can choose the use of fracture elongation values, the on Based A50 mm (if nothing else has been set in the ordering document). The following tables therefore also contain values for A50 mm. The value of A50 mm is the elongation at an initial measurement length of 50 mm and is in percent specified. The samples and their location in the sample sections are specified in EN 755-1.
