3. DEFINITIONS
The following terms are used in this standard:
3.1 Reinforcing steel of periodic profile - rods with evenly spaced on their surface at an angle to the longitudinal axis of the rod transverse protrusions (corrugations) to improve adhesion to concrete.
3.2 Smooth reinforcing steel - round rods with a smooth surface that does not have corrugations to improve adhesion to concrete.
3.3 Strength class - the standardized value of the physical or conditional yield strength of steel established by the standard.
3.4 Angle of inclination of the transverse protrusions - the angle between the transverse protrusions (grooves) and the longitudinal axis of the bar.
3.5 Step of transverse protrusions is the distance between the centers of two successive transverse protrusions, measured parallel to the longitudinal axis of the bar.
3.6 Height of transverse protrusions - the distance from the highest point of the transverse protrusion to the surface of the core of a bar of a periodic profile, measured at right angles to the longitudinal axis of the bar.
3.7 Nominal diameter of periodic profile steel (profile number) - diameter of equal cross-sectional area
