Neither do I, offhand, but virtually all the ECMA standards are
available online. Unlike some standards bodies, the ECMA believe they
should be accessible if people are to adhere to them. Anyway, ECMA 46
is at

http://www.ecma-international.org/publications/files/ECMA-TR/TR-046.PDF

BTW, many ECMA standards were adopted verbatim by ISO, so if you need a
copy of an ISO standard, and you know there's a corresponding ECMA one,
just download the ECMA version.
