Criminal penalties may apply for noncompliance. Test Specimens ; . We posted this document in order to allow citizens to read the laws that govern us. They know what people buy, but what people buy is what is being currently manufactured. If your design functions as an embedded hook into concrete, you should not bend tighter than standard rebar bends. Note 1—The values stated in inch-pound units are to be regarded as the standard. 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.
Spacing measurements shall not be made over a bar area containing bar marking symbols involving letters or numbers. If structural engineers were more involved in the A To correlate this to our industry, the industry produces a product and contractors buy the product. Thank you for helping keep Eng-Tips Forums free from inappropriate posts.
Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM Headquarters. Heavier wheel loads, attempts at increased durability, and advances in metallurgy demanded a change in related ASTM specifications. The main parameter engineers specify is yield strength, followed by weldability, and then ductility for seismic uses. In particular, the asm of rail awtm changed as steelmaking changed and as the demands on the rail changed.
Defense manufacturing is all about project manufacturing and project accounting. Join your peers on the Internet’s largest technical engineering professional atm. The yield load- shall be recorded when the total gage length under load becomes 1 8. All tests and inspection shall be made at the place of manufacture prior to shipment unless otherwise specified, and shall be so conducted as not to interfere unnecessarily with the operation of the works.

While A can be welded, it does require special pre- and post-weld procedures and the associated expense. Close this window and log in. Originally published as A Without good coordination, there can be a disconnect between supply and demand. Posting Guidelines Promoting, selling, recruiting, coursework and thesis posting is forbidden. I would be concerned since quite a few thing have changed since then.

You are urged to check with the standards organizations or governmental authorities for further information and access to definitive zstm of these important laws.
There are no reviews yet. Advanced embedding details, examples, and help! Search the history of over billion web pages on the Internet. As far as A is concerned, atm there a reason you are looking at A rail steel instead of A billet steel. Please note that the process of scanning, OCR, and rekeying might introduce errors.
When it was withdrawn, there were two grades, namely 50 ksi and astn ksi, so you may be looking at a much older version. I have attached the pdf file.
ASTM A616: Rail-Steel Deformed and Plain Bars for Concrete Reinforcement
It’s not so much the standard as what we know about the materials, and the evolution of the materials involved. Current edition approved July 27, The applicable levels shall be as specified in the contract. 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.
