Rev Letters 1

[LADO]

Does anyone know where I may get a standard on what letters are not used on a revision block due to mix-up with a number?

 

[KENAT]

ASME Y14.35 &/or ASME Y14.100.

I have neither to hand right now but basically don't use the ones that can look like numbers. I think this has been discussed before if not here then on forum781.

KENAT,

Have you reminded yourself of faq731-376 recently, or taken a look at posting policies:

What is Engineering anyway: faq1088-1484

I actually made a "complete" list of ASME acceptable revisions an excel file awhile back:

What if I needed to go to "AAA"? ;-)

ewh,

I know you are kidding, but yeah, I thought about that seriously. I read the standard carefully. Technically, triple letters are not prohibited, but they are also not mentioned by the standard. So I figured YY was a less than arbitrary point to stop the list.

Question for FCSUPER:
Could you please direct me to the article where I can find the "complete" list of the ASME acceptable rev. letters? I would like to thank you for your list but I need to pass on formal literature on the subject. I've look in ASME and can't find it.

THANKS to all for your help!!!

ASME Y14.35M-1997 Section 5.

... omitting letters "I," "O," "Q," "S," "X," and "Z".

And that's immediately followed by the instructions to use double letters once you run out of single letter revs.
