1. General requirement

The reinforcing steel the intended purpose of use of which is specified in accordance with LVS EN 1992 standard series has the following technical grades: B400B, B500A, B500B, B500C, B550B.

2. Weldability and chemical composition

The following weldability specifications are determined for all technical grades of the weldable reinforcing steel:

a) carbon equivalent;

b) content of certain chemical elements.

The maximum values of the content of certain chemical elements and carbon equivalent may not exceed the upper limit values indicated in Table 1.

Carbon equivalent value Ceq shall be calculated by using the following equation:

Ceq = C + Mn / 6 + (Cr + Mo + V) / 5 + (Ni + Cu) / 15, where

General" and with the standard LVS EN ISO 15630-1:2011 "Steel for the reinforcement and prestressing of concrete. Test methods. Part 1: Reinforcing bars, wire rod and wire".

4. Weight of one meter and tolerances

The nominal value for weight of one meter shall be calculated by taking into account the nominal cross-sectional area and using density value 7.85 x 10-6 kg/mm3.

The permissible deviations from the nominal weight of one meter may not exceed ± 4.5 %.

5. Surface profile of reinforcing steel

For the reinforcing steel which is used in accordance with LVS EN 1992 standard series surface ribbing or indentation shall be ensured.
