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

While A can be welded, it does require special pre- and post-weld procedures and the associated expense. No rejection may be made on the basis of measurements if fewer than ten adjacent deformations on each side of the bar are measured.

As an off-topic example, I am on the newly formed F44 committee on general aviation aircraft, as a pilot and consumer. Heavier wheel loads, attempts at increased durability, and advances in metallurgy demanded a change in related ASTM specifications.


Search the history of over billion web pages on the Internet. Spacing asym shall not be made over a bar area containing bar marking symbols involving letters or numbers. Reinforcing bars are evaluated on the basis of nominal weights. Test Specimens ; .

This Document Posted By Public. Ast, Sectional Area, in. In no case shall overweight of any bar be the cause for rejection. Particularly in rail steel, the carbon content is too high for proper welding. This document was posted by Public. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM Headquarters.

Originally published as A This happens because they have the funding and need to “control” their industry.

Close this window and log in. Tighter bends may damage the bar and could present a hazard to the persons doing the bending.

You are urged to check with the standards organizations or governmental authorities for further information and access to definitive versions of these important laws. A number in parentheses indicates the year of last reapproval.

Thank you for helping keep Eng-Tips Forums free from inappropriate posts. When it was withdrawn, there were two grades, namely 50 ksi and 60 ksi, so you may be looking at a much older version.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 applicable levels shall be atm specified in the contract. Be the first one to write a review. The nominal perimeter of the bar shall be 3. A measured length of the bar specimen shall be considered a6116 distance from a point on a deformation to a corresponding point on any other deformation on the same side of the bar.

In particular, the nature of rail steel changed as steelmaking changed and as the demands on the rail changed. It is used for fabricating pipe anchors. 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. The organization of the committee and subcommittees will be run by the industry mainly the manufacturers of certified light aircraft which may or may not represent the interests of the consumer very well.

Would using grade 60 be ok?

The requirements for degree of bending and sizes of pins are prescribed in Table 3. Register now while it’s still free! Measurements of Deformations 6. Where the line of deformations forms an included angle with the axis of the bar of from 45 to 70 deg inclusive, the deformations shall alternately reverse in direction on each side, or those on one side shall be reversed in direction from those on the opposite side.

In addition, standards bodies will frequently issue errata or reissue standards over time and governmental bodies may change which standards they incorporate to law. Join your peers on the Internet’s largest technical engineering professional community.

When the available scrap supply, or energy prices, or environmental regulations require changes to steel making, the producers will change the ASTM. It’s easy to join and it’s free. Criminal penalties may apply for noncompliance.
