Acronym Summary (ISO/IEC)

Because many people requested it, here is a quick summary of common acronyms:
AMD: Amendment. A relatively small set of additions to an existing standard. An Amendment describes the changes. Usually, Amendments are "rolled up" (incorporated) into the next revision of a standard. (See also TCOR)
BRM: Ballot Resolution Meeting. A meeting convened for the purposes of resolving ballot comments.
CD (and FCD): Committee Draft and Final Committee Draft. The normal development process of standards involves several successive steps, e.g., CD1, CD2, etc., FCD. A CD and an FCD are ballot the SC-level.
DIS: Draft International Standard. The last step before a fast-track document is approved as an International Standard. Note: The fast-track process is a different process than the normal development process. DIS documents are balloted and approved at the TC-level.
FDIS: Final Draft International Standard. The last step before a document (under the normal development process) is approved as an International Standard. FDIS documents are balloted and approved at the TC-level.
IEC: International Electrotechnical Commission
IS: An approved International Standard.
ISO: International Organization for Standardization
JTC1: Joint Technical Committee 1. JTC1 is a joint committee of ISO and IEC. The scope of JTC1 is information technology standardization.
L or L-member: Liaison member. A Liaison Organization does not vote.
LO: Liaison Organization. A organization the liaises with a committee.
N: A document number, such as ISO/IEC JTC1 SC32 N0000, or just SC32/N0000, or just N0000. There are no revisions or versions of document numbers (e.g., N0000R2) -- revisions or new versions are simply assigned a new document number.
NB: National Body. The primary unit of membership in ISO/IEC.
NBLO (also NBLOs):A National Body or Liaison Organization. "NBLOs" refer to all National Bodies and Liaison Organizations.
NP: New Work Item Proposal. A description of a project and scope of work. The approval of the NP signals the official beginning of a project. Typically, WPs will be submitted to the WG, WDs will be developed, successive CDs will be approved, the FDIS will be approved, and the result will be an IS. An NP is balloted an approved at the SC-level.
O or O-member: Observing member. A National Body that does not vote.
P or P-member: Participating member. A National Body that can vote.
PWI: Preliminary Work Item. A WP that discusses potential NP(s). This WP is not intended for balloting (NPs are balloted).
RG: Rapporteur Group. A committee that is responsible for writing a report, as scoped by (say) an SC. An RG is a special kind of ad hoc committee. RGs do not develop standards.
SC: Subcommittee. An SC works on a relatively broad area of technology standards within a TC. Example: SC32's work on Data Management and Interchange is all within JTC1's scope of Information Technology. SCs ballot and approve NPs, CDs, FCDs, etc., but not WDs, DISs, FDISs, etc..
TR: An approved Technical Report. A TR is developed like a standard, but its purpose is just to provide technical information and not to make requirements on implementations (conformance).
TC : Technical Committee. A standards committee with a very broad scope of work, e.g., JTC1 is information technology. Both DIS and FDIS documents are balloted and approved at the TC-level.
TCOR : Technical Corrigendum. Errata and corrections to an existing standard or amendment. (See also AMD)
WD: Working Draft, e.g., WD3 refers to Working Draft #3. WDs are developed and approved at the WG-level.
WP: Working Paper. A document submitted to a committee (e.g., WG, RG, SC, TC). Working papers are assigned document numbers ("N" numbers). A WP requires no approval -- it is merely a submission or a contribution to a committee.
WG: Working Group. A WG works a very specific area of technical standards. Usually, WGs develop standards that are scoped by approved NPs. The WGs produce successive WDs, and then CDs, and then the FDIS.
