When tested in accordnace with paragraph 5.2 of SANS 920.2005 steel reinforcement bars will comply with the appropriate values.
Type of steel	Nominal size diameter mm	Characteristic strength MPa min	Ultimate tensile strength MPa min	Elongation % min	Guage length mm
Mild	All diameters	250	15% higher than the actual yield or than the 0.20% proof stress as relevant but shall not exceed 400MPa	22%	5.65A*
High yield	All diameters	450	15% higher than the actual yield or than the 0.20% proof stress as relevant	14%	5.65A*
* A - Equivalent cross sectional area.
