Technical specification (TS) and publicly available specification (PAS)

Technical specification (TS)

A technical specification approaches an international standard in terms of detail and completeness but has not yet passed through all approval stages, either because consensus has not been reached or because standardization is seen to be premature.

 

Approval

Similar to an international standard (IS), a technical specification is normative in nature and developed according to the consensus procedure. The final vote takes place at the draft technical specification (DTS) stage, immediately following the committee draft (CD) stage.

A TS is approved by 2/3 of participating IEC Members (P-members) of an IEC technical committee or subcommittee (TC/SC)

 

Publicly available specification (PAS)

 

The objective of a publicly available specification is to speed up standardization in areas of rapidly evolving technology and generally responds to an urgent market need. It is designed to bring the work of industry fora and consortia into the realm of the IEC.

PAS are either:

  • the result of deliberations in an IEC working group or project team, when it is felt that an intermediary publication might be useful, or
  • the technical agreement in an organization external to the IEC that has an A- or D-liaison with the TC concerned.  It may be published as a dual-logo publication in which case the TC may decide to designate it as a pre-standard.

Competing publicly available specifications on the same subject are permitted. A publicly available specification does not conflict with an international standard.

Approval

A simple majority of the participating IEC Members of a TC/SC is sufficient to approve the document.
