ANSI Standard for Folding Drawings

[av14u]

I've been searching for weeks if there are any ANSI/ASME standards to fold an engineering drawing. I have found non so far.

I've been looking for such a document since I am trying to familiarize my students with both ISO and ANSI paper sizes so they get to handle both in case they need it. I am very familiar with the DIN 824-1981 to fold ISO paper sizes. I have algo encountered numerous ways people fold drawings to fit their own needs which follow no particular standard. However I still failed to find standards for ANSI drawings. The only references I ever found to fold ANSI drawings were the following:

(Page 63: Madsen's Engineering Drawinga & Design)

There is another post in this forum which mentions the Global DRM and the MIL-STD-100, but I have no access to those items.

Can any of you help me out with this? Much appreciated!

US paper sizes are not aspect based and therefore you will have a problem folding different paper sizes so they final product will be a letter size, as you can with DIN/ISO sizes where technical drawings of all sizes (A0, A1, A2, A3) can be folded to a A4 size.
A short little episode: In the late 80s our company was interchanging a lot of technical information with our German company. At one meeting we showed up with a large amount of prints neatly folded, but since they came in all different sizes the resulting pile of prints looked like a big mess. Our fiends from Europe had a neat stack of prints folded to DIN 4 with the Information block as the first page since all drawing were made to DIN standards. We spent most of our time in this meeting looking for needed information by unfolding and refolding our prints. It was not our finest hour.
The US and Canada are the only countries still using this old system. The rest of the world uses DIN/ISO.
It's like our mm/dd/yy vs. dd/mm/yyyy in the rest of the world. I guess we hold on to these old systems only because we can.
Yes - Saturday is the fourth of July 2015 (4/7/2015). The US Government uses dd/mm/yyyy.

I don't recall any guidance on folding drawings; not helped by the transition to CAD plotters and the need for the paper to be larger than the target format, leading to variable amounts of excess paper.

MIL-STD-100 is available free from

Many of the ANSI drawing sizes are based on multiples of 8.5 x 11, but not all.

US paper sizes can be folded to letter size (A-size). . .but the title blocks won't all be oriented the same way in the resulting A-size fold. Figure 1.5 from the Argonne Nat'l Lab drafting manual gets the title blocks oriented the same way, but the resulting folds are of various sizes. I'm honestly not sure whether ASME has a standard method of folding. I only recall coming across this in text books, but that doesn't mean that was based on a documented standard.

As for dates, I prefer ISO 8601, which uses YYYY-MM-DD. That makes the most sense to me because it follows the same format as all other measurements: largest units first, smaller sub-divisions next. Our company insists on using DD-MMM-YY.

Thank you everyone for their respective replies. This gives me a good idea on how to handle ANSI drawings. I always loved the consistency of ISO drawings.

Thanks again to everyone for the time you took to answer and for the posted URL!!
