Huh? The definition of ASA is American Standards Association, from which came ANSI-American National Standards Institute. Some time ago ASA was revised to ISO-International Standards Organization.
Though they do set standards for a large number of items, and I'm sure film and digital exposure is included in that collection, ASA is not defined by "sunny 16".

To be more accurate, the American National Standards Association is the group tasked with setting standards for the U.S.; they were formerly known as the American Standards Association. DIN is the corresponding German association. International Standards Organization is the corresponding international organization. At one time ASA and DIN had "competing" standards. ISO typically receives proposals for standards and decides which to accept. In 1974, they chose a standard which combined the ASA and DIN standards, but most seem to ignore the DIN "contribution".
added: ISO makes all kinds of standards. For example, when you go past a company, you will sometimes see a sign like "ISO 9001", which means they adhere to certain Quality Control standards and practices
