Anotace textu normy ASTM A996/A996M-16 :
This specification covers rail-steel and axle-steel deformed bars for concrete reinforcement. The standard sizes and dimensions of deformed bars and their number designation are presented. The carbon determination, deformation requirements and deformation measurement are provided. The material shall conform to the requirements prescribed by the specification. The yield point or yield strength shall be determined by either drop of the beam or halt in the gage of the testing machine, or by extension under load using an autographic diagram method. For all bar sizes a tension test, a bend test and a set of dimensional property tests including bar weight and spacing, height, and gap of deformations shall be made from each lot of 10 tons.

1.1 This specification covers rail-steel and axle-steel bars for concrete reinforcement. Three types of product are included, designated with a “rail symbol,” and an “R” for bars made of rail-steel and with an “A” for bars made of axle-steel. The standard sizes and dimensions of deformed bars and their number designations are given in Table 1. All sizes and grades of all types may not be readily available; manufacturers should be consulted to verify availability. 1.2 The text of this specification
references notes and footnotes that provide explanatory material.
These notes and footnotes, excluding those in tables and figures,
shall not be considered as requirements of the specification.
1.3 Type “rail symbol” and Type R are of two minimum yield strength levels, namely 50 000 psi [350 MPa] and 60 000 psi [420 MPa] designated as Grade 50 [350] and Grade 60 [420], respectively. Type A is of two minimum yield levels, namely 40 000 psi [280 MPa] and 60 000 psi [420 MPa] designated as Grade 40 [280] and Grade 60 [420], respectively. 1.4 The weldability of the steel is not a requirement of this specification. 1.5 This specification is applicable for orders in either inch-pound units (Specification A996) or SI units (Specification A996M). 1.6 The values stated in either inch-pound units or SI units are to be regarded as standard. Within the text, the SI units are shown in brackets. The values stated must be used independently of the other. Combining values from the two systems may result in nonconformance with the specification. 1.7 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. |
