"s" in a circle. it's no longer needed?
i know the answer already i believe but i have some people here that doubt me, even knowing i have the asme standard. according to asme y14.5m-1994 the "s" in a circle is no longer need, correct??. "s" use to mean "regardless of feature size"
i'm assuming the asme didn't add this back in, correct???

check out our whitepaper library.
"s" was obsoleted in the 1994 standard and i did not find anything in the 2009 standard restoring it. "s" is gone!!!!

please ref to standard y14.5 1994 appendix d paragraph d3 page 215 and fig.d-1 on page 216. rfs symbol is no longer required.

lol lol, that's the deal. i did reference the page cause we have the whole standard. but still have some people who think they know the asme standard back-wards and for-wards. one person had the gull to say "maybe they forgot to put it in" then i bring it to my boss's attention, he ones that thinks he knows it all, and he just gave me a bunch of crap and said he's not going to worry about it threw the drawing in the trash. o also he said "well the customer (delphi) had it that way so it must be current"

i wouldn't worry too much about it, given the grief you're seeing over it. the use of the symbol isn't going to result in an incorrect part.

i'm not going to worrie about any more after what just happen. i thought on the way back from lunch i'd stop by the new girl office who's doing all of our documentation and see if she understood my email. to say the least, i don't have a very good opion about her anymore. see also part of it is that they were drawing the "s" with a circle in our doc's and i was trying to convey to her that it's not needed. what a joke around here at times

to use the symbol, you have to reference the 1982 standard on the drawing. in the 1994, it is only mentioned as something that is being killed off.
the reason that it is no longer necessary is that the 1994 standard makes rfs the assumed value, instadd of mmc. so, it is actually a good idea to not use it, as it would create confusion as to which standard you are using and whether no symbols means mmc or rfs. if mmc is even suggested as default and your drawing is done to 1994, then you can be really screwed.
i would suggest that it is not correct to use circle s, especially if you are now invoking 2009 on that print.
and, the s was not "forgotten" in 2009. that comment suggesting this is extremely off-the-cuff. every statement change in the standard is debated endlessly before its inclusion or exclusion.

is there a note specifying which standard to interpret the drawing to? that will probably cover your butt if the situation arises regarding mmc that fcsuper mentions. it is no excuse to assume mmc if the drawing is to be interpreted to the '94 standard (for example) just because rfs is erroneously used.
