1) As the of yield strength take a physical δtor conditional δ0,2yield strength according to GOST 12004.
2) You can instead of full elongation 8tah determine the relative uniform elongation δp, the value of which should not be less than 2 %.
3) For reinforcing bars B500C grade 5.5 mm or less is allowed to decrease δв0,2вt.) to 1,03.

In bundles, weight 5 tons max., with banding by wire rod 6,5 mm in 6 places min. equally distributed over bundle. Each bundle is provided with 2 steel straps for multiple lifting.
