Amdt 1 1994 Amended to incorporate cold-reduced steel bars and to make
editorial corrections.
Amdt 2 2005 Amended to change the designation of SABS standards to SANS
standards, to update the definition of "acceptable" and
referenced standards, to replace the formula for the calculation
of the rib area in the test for deformed bars (5.6.1.4), to add a
note to 5.6.2.4, to delete reference to the standardization mark
and to add a bibliography.
Amdt 3 2011 Amended to update referenced standards.
Foreword
This South African standard was approved by National Committee SABS/TC 081/SC 01,
Construction materials, products and test methods – Cement, lime and concrete, in accordance with
procedures of the SABS Standards Division, in compliance with annex 3 of the WTO/TBT
agreement.
A vertical line in the margin shows where the text has been technically modified by amendment
No. 3.
Compliance with a South African National Standard cannot confer immunity from legal
obligations.

1 Scope
1.1 This specification covers the physical and mechanical requirements for carbon steel bars
intended for use as reinforcement for concrete.
1.2 It does not cover any surface treatment of the steel bars.
NOTE
a) The attention of users of steel bars for concrete reinforcement is drawn to the following standards:
SANS 282, SANS 1200 G, SANS 10100-1, SANS 10100-2 and SANS 10144.
d) Values for the cross-sectional area and the nominal mass per metre of steel bars are given in appendix C.
f) A test that may be used to determine the chemical composition of steel bars is given in appendix E.
g) Guidance on the verification of the quality of steel bars for concrete reinforcement produced to this
specification is given in appendix F.
