Technical Reports

This page specifies the actions required to prepare, approve, publish and update a Technical Report (CLC/TR).


1.1 The Technical Board (BT) or Technical Body (TB) decides to develop a CLC/TR. After approval, the CLC/TR is included as a work item in the TB work programme with a reference number.

1.2 Within the agreed timeframe, the TB drafts the CLC/TR in one of the CENELEC official languages and in accordance with CEN-CENELEC Internal Regulations – Part 3 .

1.3 Although not mandatory, WG Convenors are encouraged to circulate a working draft to TBs within the planned target date for stage 20.60, in time to allow subsequent submission to a 4-week TB commenting period.

1.4 The TB Secretary monitors via Projex-online the development of their WIs to ensure delivery by the set deadline (stage 30.99) and take measures in case of delay, to avoid the risk of deletion of WIs in unjustified cases:

  • the initially planned (stage 30.99) for TR can be modified once with a simple agreement of the TB Officers, in coordination with the WG Convenor, via email to;
  • a tolerance for TR can be requested once by the TB Officers in agreement with the WG Convenor, via email to

1.5 The TB Secretary submits, within the planned target date for stage 30.99 ‘Vote’, the CLC/FprTR in the relevant reference language version, via the Submission Interface to CCMC for processing in two electronic formats, an agreed revisable WORD file and a non-revisable PDF file together with separate figure files, if any.

1.6 CCMC checks that all the documentation and electronic files have been supplied and that the deliverable corresponds to the database records.

1.7 No translation period prior to the launch of the vote is foreseen. The relevant NCs prepare the translation of the titles and provide CCMC with these translations prior to the launch to vote.

1.8 CCMC circulates the CLC/FprTR to all the CENELEC National Committees, the Partner Organizations, the Affiliates, the EC and EFTA Secretariat, the TB Chair and Secretary. This is done on a weekly basis.

1.9 During the vote, the CENELEC National Committees submit their vote and their comments within the prescribed 12-week period. The CENELEC National Committees are required to cast unconditional votes and to justify any abstention or negative vote.

After the deadline of the vote, CCMC establishes the voting report, compiles the comments and dispatches both the voting report and the comments to the CENELEC Members, the Partner Organizations, the Affiliates, the EC and EFTA Secretariat, the TB Chair and Secretary.

1.10 If the CLC/FprTR is approved, CCMC (in consultation with the TB Secretary) incorporates the editorial changes in the reference language version. The finalized text is sent by CCMC to the TB Secretary for a 2-week proofing period.

CCMC is responsible for finalizing the publication of all CLC/TR deliverables.

If, during the voting period, comments are received that request an alteration of the technical content of the CLC/FprTR, CCMC will not take these into account. CCMC will only implement purely editorial comments. No technical changes shall be made to the text following a positive approval procedure. The TB shall take into account any technical comments in a future revision of the text.

Exactly 5 weeks after a positive voting result has been circulated, the text is considered ratified (dor = date of ratification).

1.11 If the CLC/FprTR is not approved, a decision is taken by the responsible body to redraft the CLC/FprTR (go back to 1.2) or to stop the work. The TB informs CCMC accordingly (

1.12 Once the approval of the TB Secretary is received following the proofing period, CCMC dispatches the CLC/TR to the CENELEC National Committees, the Partner Organizations, the Affiliates, the EC and EFTA Secretariat, the TB Chair and Secretary. This is done on a weekly basis.  No translation period prior to publication is foreseen, however any incoming translations to CCMC are circulated one week after they are delivered to CCMC.

1.13 The CLC/TR is not amended but replaced by a new edition with the same number and new date of edition.  Corrigenda are possible.

1.14 It is recommended that Technical Reports are regularly reviewed by the responsible technical body to ensure that they remain valid.
