Technical Specifications (TS)
Technical Specifications are often published when the subject under question is still under development or when insufficient consensus for approval of an International Standard is available.
Technical Specifications approach International Standards in terms of detail and completeness, but have not yet passed through all approval stages either because consensus has not been reached or because standardization is seen to be premature.
A Technical Specification is similar to an International Standard (IS) in that it is normative in nature, developed according to consensus procedures. A TS is approved by two/thirds of the Participating Members (P-Member) of an IEC Technical Committee (TC) or Subcommittee (SC).
The procedure for approval is similar to that for a standard, except that the final vote takes place at the Draft Technical Specification (DTS) stage, immediately following the Committee Draft (CD) stage.
