Join your peers on the Internet’s largest technical engineering professional community. A was withdrawn in Note that many of these documents had to be procured adtm the used marketplace.

Heavier wheel loads, attempts at increased durability, and advances in metallurgy demanded a change in related ASTM specifications. This happens because a66 have the funding and need to “control” their industry. Click Here to join Eng-Tips and talk with other members! Producers try to respond to market pressure higher strength, for examplebut there are complications, like ACIwhich limits the use of high strength bars for functional and safety reasons.

Note 1—The values stated in inch-pound units are to be regarded as the standard. Search the history of over billion web pages on the Internet.

Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of zstm of such rights, are entirely their own responsibility.


Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM Headquarters. Are you an Engineering professional? The applicable levels shall be as specified in the contract.

Where concrete crushing inside a66 bend is not critical, tighter stirrup bends can be used. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.

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. I would be concerned since quite a few thing have changed since then. The dynamic of this is that it is the producers who sit on ASTM committees, because those are the people committed to the work.

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

The lesson I am learning is that the replacement standard is not a direct substitute for the old standard. To correlate this to our industry, the industry produces a product and contractors buy the product.

Criminal penalties may apply for noncompliance. In no case shall overweight of any bar be the cause for rejection. It is used for fabricating pipe anchors. Spacing measurements shall not be made over a bar area containing bar marking symbols involving letters or numbers. As an off-topic example, I am on the newly formed F44 committee on general aviation aircraft, as a pilot and consumer.

Current edition approved July 27, Or use another weldable bar stock if deformations are not required. The main parameter engineers specify is yield strength, followed by weldability, and then ductility for seismic uses. Search the history of over billion web pages on the Internet. Reinforcing bars are evaluated on the basis of nominal weights.

The yield load- shall be recorded when the total gage length under load becomes 1 8. Download Now Defense manufacturing is all about project manufacturing and project accounting. Thank you for helping keep Eng-Tips Forums free from inappropriate posts. Would using grade 60 be ok?
