ASTM-A615/A615M:20 pdf free download – Standard Specification for Deformed and Plain Carbon-Steel Bars for Concrete Reinforcement.
11. Permissible Variation in Weight [Mass]
11. 1 Deformed reinforcing bars shall be evaluated on the basis of nominal weight Imassi. The weight [mass] determined using the measured weight [mass] of the test specimen and rounding in accordance with Practice E29, shall be at least 94 % of the applicable weight [mass] per unit length prescribed in Table 1. In no case shall overweight [excess mass] of any deformed bar be the cause for rejection.
11 .2 Weight jmassj variation for plain bars shall be computed on the basis of permissible variation in diameter. For plain bars smaller than /8 in. [9.5 mm] in diameter, use Specification A510/A51OM. For larger plain bars up to and including 2½ in. j63.5 mm] in diameter, use Specification A6/A6M.
12. Finish
12.1 The bars shall be free of detrimental surface imperfections.
12.2 Rust, seams, surface irregularities, or mill scale shall not he cause for rejection, provided the weight [massi, nominal dimensions, cross-sectional area, and tensile properties of a hand wire brushed test specimen are not less than the requirements of this specification.
12.3 Surface imperfections or flaws other than those specitied in 12.2 shall he considered detrimental when specimens containing such imperfections fail to conform to either tensile or bending requirements. Examples include, hut are not limited to, laps, seams, scabs, slivers, cooling or casting cracks, and mill or guide marks.
NOTE 7—Deformed reinforcing bars intended for epoxy coating applications should have surfaces with a minimum of sharp edges to achieve proper coverage. Particular attention should be given to bar marks and deformations where coating difficulties are prone to occur.
NOTE 8—Deformed reinforcing bars destined to be mechanically- spliced or butt-spliced by welding may require a certain degree of roundness in order for the splices to adequately achieve strength requirements.
13. Number of Tests
13.1 One tension test and one bend test shall be made of each bar size rolled from each heat.
16. Test Reports
16.1 The following information shall be reported on a per heat basis. Report additional items as requested or desired.
16.1.1 Chemical analysis including the percentages of carbon. manganese. phosphorus, and sulfur.
16.1.2 Tensile properties.
16.1.3 Bend test results.
16.2 A Material Test Report, Certificate of Inspection, or similar document printed from or used in electronic form from an electronic data interchange (EDT) transmission shall be regarded as having the same validity as a counterpart printed in the certifier’s facility. The content of the ED transmitted document shall meet the requirements of the invoked ASTM standard(s) and conform to any ED! agreement between the purchaser and the manufacturer. Notwithstanding the absence of a signature, the organization submitting the ED! transmission is responsible for the content of the report.
NOTE 12—The industry definition invoked here is: EDI is the computer to computer exchange of business information in a standard format such as ANSI ASC X12.
