ASTM A193

[unclesyd]

What is the official status of this specification?

Why is it not published the booklet of fastener specifications published by ASTM? Hasn't been since 1995.

What is the status of the specification in respect to ASME?

Regarding ASME B&PV Code
ASME SA 193 is still endorsed by the 2004 Edition of ASME B&PV Code and is nearly identical to ASTM A 193-98, with the exception of several editorial changes in Table 1, Note 6 and 3.1.1 and 19.4 and Table 2.

I checked the ASTM web site, and ASTM A 193-04c Standard Specification is still active.

metengr,
Appreciate the 2004 Edition of the B&PV Code information as my normal sources don't have their copies as of yet.

My fastener friend biggest movers are B8/B7/B16 fasteners to B&PV industry and I was helping him wonder until we could find out. This has been a nagging problem since 1995. In the fastener business it bad enough in just assuming that the "purchaser" is ordering the correct fastener and you are supplying the proper materials and not having the possibility of assuming some type of liability if the standard/specification is non existent.

On the ASTM side.
One big question that keeps popping up in the fastener business is why the standard isn't published in the ASTM Fastener Handbook. People who use this booklet are questioning why the specification isn't in the booklet. I guess one would have to purchase the Fastener Handbook and then purchase the individual specification to get the updates if there was any question.
In short people keep asking what is the substitute for A193. Suppliers who mainly use this booklet have also questioned about supplying an MTR to a nonexistent/phantom specification/standard. You buy a new Fastener Handbook every year and still don't have the latest information. This has even became a problem with overseas suppliers.

According to

it is in the 2003 fastener book. Someone just like you must have complained to ASTM.

HgTX,
Appreciate the reference.
I'll have to confess that I only looked at the 2005 and 1995 booklets yesterday based the question at the time. It wasn't in the 2005 and was in the 1995. It will have to wait until Tuesday and I'll get back by the office and check the intervening years.

Having been exposed to both sides of the fastener business, specifying and selling end, I’m beginning to believe that supplying a quality fastener is the more complicated end when you have to consider all specifications/standards of each discipline and the now convoluted supply chain.

HgTX the purchasing of fastener, construction side, of your business suffers badly from almost a complete lack understanding of the specifications/standards when it come procuring fasteners, especially for small and medium construction. I need to compile a number of the queries and RFQ’s for A325 and others and send it to some professor in B & C field.
Yesterday a quote came in asking forA325 5/8"-1" in various lengths, 3" increments, to be fully threaded. The reason for the request was that the job was on a fast track and the supervisor didn’t want his men to worry about bolts while overhead. The inspector never checks the overhead.

metengr,

While I exploring the ASTM site there was a reference to a blanket specification A962 that covers certain aspects the more common bolting standards. Have you encounter this standard?
I have requested that it be ordered.

 

[HgTX]

I can't seem to find anything other than the 2003 book. I must be looking for the wrong thing.

A 962 covers provisions common to A 193, A 194, A 320, A 437, A 453, and A 540. If memory serves correctly, these provisions were deleted from those specs, so if you use any of them you now need A 962.

Unclesyd;
In my direct involvement with ASME B&PV Code, I had heard about ASTM A 962, which is titled “ Specification for Common Requirements for Steel Fasteners or Fastener Material, or Both, Intended for use at any Temperature from Cryogenic to the Creep range” but have not dealt directly with it because the current adopted ASME SA 193 Standard Specification is the 1998a Edition, and does not reference ASTM A 962. The ASTM A 962 Standard Specification - 1999 Edition had been adopted by ASME, Section II, and is identical to the ASME SA 962 Standard Specification.

HgTX,
I look at the actual booklets and the last one it's in is 1995.
The 1995 booklet is Volume 15.08 Fasteners.
The 2005 booklet is Volume 01.08 Fasteners & Rolling Element Bearings. Section I; Iron and Steel Products.

metengr,
The ASTM A692 isn't in the 2005 ASTM Fastener Booklet either.


As stated before the majority (80%)of orders since 01/01/05 callout ASTM A193 as the purchasing specification for studs. The remaining just callout B7, B16, B8, etc. There is not one callout of ASME A193 material. I'd be willing to bet that you could count the people on your hands that sell fasteners who have any knowledge of the ASME Standards. Talked with 2 large manufacturers and both still use the ASTM standards to purchase bar stock.
I think one would be covered as ASTM A193 is still listed as active standard.
I sure would hate to started explaining this to some lawyer.

Addition:
We have received information that there are some very bad ASTM A194 2H nuts in circulation. As far as we can find out there aren’t any in the US, yet. They were shipped mainly to Southeast Asia and the Middle East from Korea. The nuts are supposedly very brittle and have split while tightening or shortly after if exposed to any temperature.

unclesyd, by "fastener book" it appears you mean the Annual Book of ASTM Standards volume labeled "Fasteners" (which used to be 15.08 and is now 1.08). I'd thought you meant the compilation volume ASTM International Standards for Mechanical Fasteners and Related Standards for Fastener Materials, Coatings, Test Methods, and Quality.

A 193 is in the compilation, and the compilation exists precisely because not everything fastener-related is in Vol. 1.08. Unfortunately it doesn't look like they publish the compilation every year. You should contact them about that.

I once tried asking why not all the fastener-related standards were covered by the fastener committee (and thus in the fastener volume) and didn't really get a good answer. It's always seemed strange to me that bolts would be under one committee and nuts another.
