a) Rm / Re1.03 and Agt 2.0 for center lines ≤ 5.5 mm
b) Agt for coils + 0.5%
c) Rm / Re min. 1.13 and Agt 7.0% for center lines ≤ 12 mm
d) Maximum tension ripple 2σa with a maximum tension 0.6 Re,k (300 MPa) and 1 million alternations. For spot-welded reinforcing mesh B500B and B500C, 2σa is at least 100 MPa. For coil-oriented products, 2σa is at least 100 MPa, unless a higher value (≤ 175 MPa) is statistically demonstrated for the maximum diameter used and for the targeting machine (type) concerned.
e) For lattice girders, the lower bars must comply with B500A and/or B500B with the fR/P requirement. The upper bars and diagonals may be reinforcing steel with only the requirements of Re,d and the chemical composition.
f) For coils fR (ribbed) + 15%, fP (dented) + 5%. No requirement for weakly profiled/dented reinforcing steel (lattice girders).
