This standard is subject to a6616 at any time by the responsible technical committee and must be reviewed every five years and if not revised, either reapproved or withdrawn.

Cross- Sectional Area, in. I have attached the pdf file. Uploaded by Public Resource on July 1, No rejection may be made on the basis of measurements if fewer than ten adjacent deformations on each side of the bar are measured. This specification has been approved,for use by agencies of the Department of Defense and for listing in the DoD Index of Specifications and Standards.

ASTM A616: Rail-Steel Deformed and Plain Bars for Concrete Reinforcement

Test Specimens ; . Spacing measurements shall not be made over a bar area containing bar marking symbols involving letters or numbers. Join your peers on the Internet’s largest technical engineering professional community. Note 1—The values stated in inch-pound units are to be regarded as the standard. Resources Digital Transformation may be defined in a number of different ways by analysts or enterprise software vendors.

In no case shall overweight of any bar be the cause for rejection. Heavier wheel loads, attempts at increased durability, and advances in metallurgy demanded a change in related ASTM specifications.


For bending properties test provisions of the nearest smaller nominal diameter deformed bar size shall apply. Students Click Here Join Us! Material and Manufacture 4. Note 3—A lot is defined as all the bars of one bar number and pattern of deformation contained in an individual shipping release or shipping order.

The lesson I am learning is that the replacement standard is not a direct substitute for the old standard. Criminal penalties may apply for noncompliance. Also, true rail steel bar are not typically fabricated only cut to straight lengthssince these bars are not as ductile as other types of reinforcing steel.

ASTM specs change in response to the supply, not typically because of changes in demand.

It’s not so much the standard as what we know about the materials, and the evolution of the materials involved. Digital Transformation may be defined in a number of different ways by analysts or enterprise software vendors. Current edition approved July 27, Posting Guidelines Promoting, selling, recruiting, coursework and thesis posting is forbidden.

The standard sizes and dimensions of deformed bars and their number designations shall be those listed in Table 1. When it was withdrawn, there were two grades, namely 50 ksi and 60 ksi, so you may be looking at a much older version. The main parameter engineers adtm is yield strength, followed by weldability, and then ductility for seismic uses.


As an off-topic example, I am on the newly formed F44 committee on general aviation aircraft, as a pilot and consumer. This document was posted by Public. Advanced embedding details, examples, and help!

The nominal perimeter of a6166 bar shall be 3. We posted this document in order to allow citizens to read the laws that govern us. A measured length of the bar specimen shall be considered the distance from a point on a deformation to a corresponding point on any other deformation on the same side of the bar. Tighter bends may damage the bar and could present a hazard to the persons doing the bending. Please note that the process of scanning, OCR, and rekeying might introduce errors.

The dynamic of this is that it is the 6a16 who sit on ASTM committees, because those are the people committed to the work.

The American Society for Testing and Materials takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard. By Authority of the Code of Federal Aztm The requirements for degree of bending and sizes of pins are prescribed in Table 3.

Measurements of Deformations 6.

Aastm applicable levels shall be as specified in the contract. Note that many of these documents had to be procured on the used marketplace.

CRSI now has a another design engineer liaison to the committee.
