AES is included in the ISO / IEC 18033-3 standard.

An international standard for this process, ISO 16622 Meteorology — Sonic anemometers / thermometers — Acceptance test methods for mean wind measurements is in general circulation.

The same standard was ratified by the International Organization for Standardization as ISO / IEC 9899: 1990, with only formatting changes, which is sometimes referred to as C90.

This standard has been withdrawn by both INCITS and ISO / IEC.

In March 2000, ANSI adopted the ISO / IEC 9899: 1999 standard.

This standard has been withdrawn by ISO / IEC, but is still approved by INCITS.

The symbol for bit, as a unit of information, is either simply " bit " ( recommended by the ISO / IEC standard 80000-13 ( 2008 )) or lowercase " b " ( recommended by the IEEE 1541 Standard ( 2002 )).

With ISO / IEC 80000-13, this common meaning was codified in a formal standard.

Today the harmonized ISO / IEC 80000-13: 2008 – Quantities and units — Part 13: Information science and technology standard cancels and replaces subclauses 3. 8 and 3. 9 of IEC 60027-2: 2005, namely those related to Information theory and Prefixes for binary multiples.

The Standards council of Canada then sponsored, on January 21, 1993, the registration of an encoded character set for use in ISO / IEC 2022, in the ISO-IR international registry of coded character sets.

A proposal was posted by Michael Everson for the Blissymbolics script to be included in the Universal Character Set ( UCS ) and encoded for use with the ISO / IEC 10646 and Unicode standards.

The proposed encoding does not use the lexical encoding model used in the existing ISO-IR / 169 registered character set, but instead applies the Unicode and ISO character-glyph model to the Bliss-character model already adopted by BCI, since this would significantly reduce the number of needed characters.

* Michael Everson's First proposed encoding into Unicode and ISO / IEC 10646 of Blissymbolics characters, based on the decomposition of the ISO-IR / 169 repertoire.

Right-to-left scripts were introduced through encodings like ISO / IEC 8859-6 and ISO / IEC 8859-8, storing the letters ( usually ) in writing and reading order.

It is also extended through the universal big-endian format clock time: 9 November 2003, 18h 14m 12s, or 2003 / 11 / 9 / 18: 14: 12 or ( ISO 8601 ) 2003-11-09T18: 14: 12.

* ISO / IEC 15408

The algorithm is also specified in ANSI X3. 92, NIST SP 800-67 and ISO / IEC 18033-3 ( as a component of TDEA ).

The Dublin Core became ISO 15836 standard in 2006 and is used as a base-level data element set for the description of learning resources in the ISO / IEC 19788-2 Metadata for learning resources ( MLR ) -- Part 2: Dublin Core elements, prepared by the ISO / IEC JTC1 SC36.

ISO 2022 then provided conventions for " switching " between different character sets in mid-file.

GTK + applications on Linux support the ISO 14755-conformant hex Unicode input system ; hold while tapping U, then type 2022 and press to insert a • or hold while tapping U, then type B7 and press to insert a midpoint.

The structure of Big5 does not conform to the ISO 2022 standard, but rather bears a certain similarity to the Shift JIS encoding.

* ISO / IEC 2022 ( based on sequence codes to switch between Chinese, Japanese, Korean character sets-hence without unification )

These codes ( 0x21 – 0x7E, as corresponding high bit set bytes 0xA1 – 0xFE ) also used in various multi-byte encoding schemes for languages of East Asia, such as ISO 2022, EUC and GB 2312.

Sometimes, the use of the term " DBCS " can imply an underlying structure that does not comply with ISO 2022.

Many of the character sets included as ISO / IEC 2022 encodings are ' double byte ' encodings where two bytes correspond to a single character.

ISO / IEC 2022 was developed as a technique to attack both of these problems: to represent characters in multiple character sets within a single character encoding, and to represent large character sets.

To represent multiple character sets, the ISO / IEC 2022 character encodings include escape sequences which indicate the character set for characters which follow.

To represent large character sets, ISO / IEC 2022 builds on ISO / IEC 646's property that one seven bit character will normally define 94 graphic ( printable ) characters ( in addition to space and 33 control characters ).

Although ISO / IEC 2022 character sets using control sequences are still in common use, particularly ISO-2022-JP, most modern e-mail applications are converting to use the simpler Unicode transforms such as UTF-8.

ISO / IEC 2022 coding specifies a two-layer mapping between character codes and displayed characters.

To get the EUC form of an ISO-2022 character, the most significant bit of each 7-bit byte of the original ISO 2022 codes is set ( by adding 128 to each of these original 7-bit codes ); this allows software to easily distinguish whether a particular byte in a character string belongs to the ISO-646 code or the ISO-2022 ( EUC ) code.

The 748 code contains all of GB2312, but is not ISO 2022 – compliant and therefore not a true EUC code.

( It uses an 8-bit lead byte but distinguishes between a second byte with its most significant bit set and one with its most significant bit cleared, and is therefore more similar in structure to Big5 and other non – ISO 2022 – compliant DBCS encoding systems.

MARC-8 is based on ISO 2022 and allows the use of Hebrew, Cyrillic, Arabic, Greek, and East Asian scripts.
