Specification Practices...
(OP)
I have found in a drafting manual that references:
MIL-STD-490 - Specification Practices.
MIL-S-83490 - Specification, Types and Forms.
DOD-STD-100 - Engineering Drawing Practices.
MIL-STD-961 - Outline of Forms and Instructions for the preparation of specification.
It specifies in 5.6 Underlining - Never underline any portion of a paragraph or word for the sake of emphasis.
I can not find anything regarding underlining in ASME Y14.5M-1995 or ASME Y14.100M-1998. Is there anything in ASME specs that outline the use of underlining on Engineering Drawings?

Take care & have fun!

An underlined section of text might be confused with a missed strike-out.

Eradicating fluid and sepia paper - that's back when drafting was an art!
RE: Specification Practices...
My erradicating fluid was unopened for 15 years, I recently opened it and it was dryed up and smelled really bad. Had to find some ammonia to finish off the day! (just kidding)

However, ASME Y14.5M-1994. "Dimensioning and Tolerancing", paragraph 1.7.9 states that, for a dimension not to scale, the defining dimension is to be underlined with a straight thick line.
So, there are cases where underlining is acceptable.

RE: Specification Practices...
But, in a "typeset" (i.e. where the majority of the information is contained in written text) specification or standard, generally no underlining is used in the body of the text. All of the text was/is supposed to be taken as gospel (i.e. "thou shalt"), thus no need for emphasis, or at least (again) that's how I learnt it (been a few years since I had to write a spec conforming to MIL/aero standards). Underlining in the old days was used to "set off" the paragraph and section numbering of the document (i.e. make it stand out better on the printed page for clarity). Nowadays I see boldface fonts used for the same purpose in ISO and similar standards.
