Like almost everyone, rather than pay Swiss francs, I downloaded ITU-T H.262 
(https://www.itu.int/rec/T-REC-H.262) which is the free version of ISO/IEC 13818-2 and is the only 
part of interest (and that includes detailed descriptions of the differences between H.262 and 
ISO/IEC 13818-2). The quotations I previously listed are from ITU-T H.262.

Nonetheless, the Motion Picture Experts Group certainly seems to think it has standards 
(https://mpeg.chiariglione.org/who-we-are):
"Welcome to the ISO/IEC JTC 1/SC 29/WG 11 web site also know as MPEG, the Moving Picture Experts 
Group. The MPEG acronym is also used to indicate a suite of ISO/IEC digital media standards 
developed by this JTC 1 Working Group."
