UNO or UON

UNO or UON

UNO or UON

(OP)
Hello All,

which one do you normally use?

UNO, unless noted otherwise
or
UON, unless otherwise noted.

RE: UNO or UON

Neither - any abbreviation can be misinterpreted unless it is defined in a recognized standard, and the standard is referred to on the drawing.

RE: UNO or UON

I agree, unclear TLA's are TBA.

RE: UNO or UON

What the heck does UNO or UON mean?

I completely agree with dgallup.

RE: UNO or UON

I also agree, but have seen "Unless otherwise specified..." frequently.

RE: UNO or UON

Spoonful, if working to ASME standards and referencing Y14.100 (top level drafting std) you implicitly invoke ASME Y14.38 Abbreviations And Acronyms.

My 2002 version gives neither UON or UNO as approved acronyms.

It does give UOS for Unless Otherwise Specified.

Otherwise TLA's only make sense if they are defined either on the drawing or by a standard somehow referenced by the standard.

RE: UNO or UON

(OP)
Thanks for sharing your opinions.
I agree that this abbreviation need to noted in the drawing tile block.

But I must say I see the term "noted" more often than "specified"
