Does anybody have a copy of ANSI x3.21-1967, now known as ANSI INCITS 21-1967?
Nothing like a timely answer, but the Internet Archive does,
as "Federal Information Processing Standards Publication: rectangular holes in twelve-row punched cards" —
https://archive.org/details/federalinformati13nati/mode/2up , aka FIPS PUB 13.
A typical punched card *hole* was 3.175 mm tall and 1.397 mm wide.
The only available IBM card stock specification¹ suggests it was 161.1 gsm ("99 pound basis weight") so each chad had a mass of 0.000715 g.
Maybe the only Fortran 2013 program ever punched on cards.

The Living Computer Museum has an 029 keypunch, and when they were open (before Covid restrictions) I punched a Fortran 2008, and later a Fortran 2013
program on one. I believe the latter used a DO CONCURRENT statement.
(And both were fixed-form, as you might expect on cards.)

I doubt that it is the only Fortran 2018 [sic] program ever to be
punched onto cards. Why? Well, with very few exceptions a
valid Fortran 77 code is a valid Fortran 2018 code. I know I used
punched cards in the 1981/82 time frame. I still have a deck
for computing one's biorythm someplace in my trove of old stuff.
I have often wondered if there was some standard that covered the practice of putting an oblique
ink stripe on the side of a deck to help keep the cards in order.
That was the analog version of radix sorting, was it not?

ANSI will sell me one for $30.00. INCITS claims not to have a copy on file.
A question it could answer came up informally at the last Fortran committee meeting, so I had hoped INCITS would send me one. No dice.
