Definitions The following definitions are applicable to this Part. 3.1 Hot rolled bars The steel bar delivered under hot rolling condition; its metallurgical structure is mainly composed of ferrite and pearlite, no other textures (for instance, the β-martensite appeared on the base circle) are permitted to exist, which may influence the usability of steel bar. 3.2 Hot rolled bars of fine grains The grain refining steel bar formed by applying control rolling and cooling technologies during the hot rolling process; its metallurgical structure is mainly composed of ferrite and pearlite, no other textures (for instance, the β-martensite appeared on the base circle) are permitted to exist, which may influence the usability of steel bar, moreover, the grain size is no thicker than 9-level of the grain size. 3.3 Ribbed bars The cross-section of ribbed bars is round, and it belongs to the ribbed bar of concrete. 3.4 Longitudinal rib Longitudinal rib indicates the uniform continuous rib parallel to the steel bar axis. 3.5 Transverse rib Transverse rib indicates those rib un-parallel to the steel bar axis. 3.6 Crescent ribbed bars Crescent ribbed bars indicate the longitudinal section of transverse rib is crescent and disjoints with longitudinal rib. Crescent ribbed bars indicate the longitudinal section of transverse rib is crescent and disjoints with longitudinal rib. 3.7 Nominal diameter Nominal diameter indicates the diameter of a circle equals to the nominal cross-sectional area of the steel bar. 3.8 Specific projected rib area Specific projected rib area indicates the ratio between the projected area of transverse rib on the vertical plane of the steel bar axis, and the product between steel bar nominal perimeter and transverse rib spacing. 3.9 Rib height The rib height can be calculated by the space from rib peak to the core surface, which is perpendicular to the steel bar axis. 3.10 Rib spacing Rib spacing indicates the space between two adjacent transverse rib centers, which parallel the steel bar axis. 3.11 Characteristic value The characteristic value indicates the percent place value corresponding to certain required probability during infinite multiple testing periods.
