Ron,
The sizes that are in the standard already are iso, but the new ones that
have ISO sizes times N, should be asme, right? Its the ASME standard that
defines the multiples of sizes, not an ISO standard. Now that we have
agreed to always have a class name, the asme class name can also imply mm.
(though the one asme-f may cause us a problem, since it is in inches, if we
also have to have an f that is a different size, but also in inches).

Tom,
In the IPP document these are prefixed with "iso-". So I
suggest we continue as in IPP, whether it was right or
wrong.

and a different ASME F size
I finally got my copy of the ASME Y14.M-1995 Metric Drawing Sheet Size and
Format Standard. Some of its sizes are in IPP, so we should probably add all
of them to the PWG Media Standardized Names standard.
In addition to having A0 to A4 (with the usual dimensions), they have
Elongated Sizes for A3 and A4 in which the standard size is placed N times
with the long edge next to long edge, and Extra-Elongated Sizes for A0 to
A4.
Elongated Sizes in mm:
A3X3 420 891
A3X4 420 1189
A4X3 297 630
A4X4 297 841
A4X5 297 1051
Extra-Elongated Sizes in mm:
A0X2 1189 1682
A0X3 1189 2523
A1X3 841 1783
A1X4 841 2378
A2X3 594 1261
A2X4 594 1682
A2X5 594 2102
A3X5 420 1486
A3X6 420 1783
A3X7 420 2080
A4X6 297 1261
A4X7 297 1471
A4X8 297 1682
A4X9 297 1892
ISSUE: Should we prefix these sizes with 'asme-' or not?
The Media Size Self Describing Names would be either:
a3x3.4200-8910 or asme-a3x3.4200-8910
a3x4.4200-11890 or asme-a3x4.4200-11890
...
Since all of the metric sizes have a prefix of iso, jis or jpn, I suggest we
have the asme- prefix, ok?
While we are at it I checked the ASME Y14.1-1995 Decimal Inch Drawing Sheet
Size and Format sizes as well.
ISSUE: ASME F size is NOT the same as our PWG na-f.44000-68000 size!
The A through F sizes are the same as we have already in the document,
except for F, so all we need to do is add a reference number in the Ref
column. However, our na-f.44000-68000 does NOT agree with the ASME F size.
In the ASME standard, F is 28 by 40 inches. Yes, in the ASME standard, F is
smaller than E; E is 34 by 44 inches (same as in our standard).
There is no reference for na-f.44000-68000, so I wonder where it came from?
If na-f.44000-68000 is different from the ASME F size, we can add
na-asme-f.28000-40000 as distinct from our na-f.44000-68000, or is
f.44000-68000 a mistake in our standard?
The so-called Roll Sizes G through K are in inches, but seem to have a
variable number of segments, so I don't think we have any good way to name
these sizes.
Size Vert Min Max
G 11 22.5 90
H 28 44 143
J 34 55 176
K 40 55 143
