ASTM A656-93
ASTM A656-93
(OP)
I’m hoping you can answer a question. Our customer calls a material specification as ASTM A656-93, grade 80. When we purchase this we only specify ASTM A656 GR 80, not including the -93. What is the significance of “-93”? I do not see this as a type in the spec.
Thanks for your insight into this. Diego

The latest edition is from 2013.

There is no reason to order to old versions.
This is different in the Code world of ASME, there the versions can matter a lot.

It is common for specification writers and purchasing types to not understand the terminology. As important as I think it is, I routinely see the wrong versions of standards referenced in specifications.

RE: ASTM A656-93
Is there any ASTM reference or other document that states the latest version be used unless noted otherwise? I understand why this is a best practice.
The reason I ask is there is a state agency (corrections) that has their own specifications for construction projects. These specifications include the year/version on all ASTM standards and they expect their consultants to update the ASTM versions in the specifications for all new projects. I tend to think this time-consuming, tedious task is a monumental waste of time. Typically, specifications have a general statement covering the version for all standards (e.g. the most current standard published at the time the contract is signed or some other specific date/milestone).
RE: ASTM A656-93
Some ASTM specs actually say to report the rev, and others tell you not to. I depends on when they were last reviewed and by which committee.

Thanks for the replies
Ron,
It becomes somewhat troublesome when the IBC referenced standards are not coordinated. For instance the 2012 IBC references ACI 318-11 and ASTM C150-07. While ACI 318-11 references ASTM C150-09. In reality, it does not make a whole lot of difference since Portland cement hasn't changed between 2007 and 2009. This lack of coordination in the IBC referenced standards is not uncommon. The ICC would have a tough time trying to coordinate everything since the version of ASTM standards in ACI 318-11 references don't match ACI 530.1-11.
