From OCG


The present document endeavours to provide step-by-step guidance on the essential elements, most common practices and responsibilities of a Technical Body (TB), Industry Specification Group (ISG) and Special Committee (SC) and ETSI Project (EP) Chair.

It has been formatted to be used as a quick reference guide together with the ETSI Directives ( If in any doubt regarding the application of the correct procedures, the ETSI Secretariat can always provide guidance.

The scope of this guide covers all ETSI ISGs, TBs, SCs and EPs, but it does not cover ETSI Partnership Projects (EPP) (e.g., 3GPP and oneM2M). It is to be used in conjunction with the ETSI Delegate’s guide and the ETSI Rapporteur’s guide.

A Special Committee may be established by the GA for defined tasks and follows the same rules as TBs (as per TWPs) unless otherwise stipulated in their ToR.

Obligations and Responsibilities of the Chair

The primary duties of a Chair:

  • Ensure an efficient operation of the TB/ISG/SC/EP and its Working Groups (in conjunction with the Vice-Chair(s), Working Group (WG) Chair(s) and Vice-Chair(s))
  • Ensure the TB/SC/ISG/EPs’ activities adhere to ETSI Directives and its rules, policies and procedures
  • Ensure that the Work Programme is kept up to date
  • Maintain strict impartiality and act in the interest of ETSI and its members
  • Ensure that the ETSI Guidelines for Antitrust Compliance are strictly observed
  • Remind the members of the TB/ISG/SC of their statutory obligations to submit IPR disclosures
  • Endeavour to reach consensus on all issues, including the approval of draft ETSI deliverables
  • Report to the OCG, Board and the General Assembly on the activities of the TB/ISG/SC/EP upon request.

ETSI Chair’s Responsibilities on Antitrust Compliance, IPR and Confidentiality


One of the primary duties of the Chair is to take care that the ETSI Guidelines for Antitrust Compliance are strictly observed. The Chair has a duty to remind the TB/ISG members of their obligations to submit IPR disclosures

Chair’s Responsibilities on IPR

Throughout the standardization process the Chair shall take the actions as laid down in the sections of the Guide on IPRs, to facilitate the identification of Essential IPRs. This includes disallowing e.g., discussions on commercial issues in the TB/ ISGs and/or discussions on details of specific licensing terms and conditions.

Make call for IPRs in TB/SC or ISG meetings

Every TB/SC or ISG meeting starts with a “Call for IPRs” performed by the Chair. e.g., this may consist of the following sentences for a TB meeting:

“The attention of the members of this Technical Body is drawn to the fact that ETSI members shall use reasonable endeavours under Clause 4.1 of the ETSI IPR Policy, Annex 6 of the Rules of Procedure, to inform ETSI of Essential IPRs in a timely fashion. This section covers the obligation to notify its own IPRs but also other companies’ IPRs. The members take note that they are hereby invited:

  • to investigate in their company whether their company does own IPRs which are, or are likely to become Essential in respect of the work of the Technical Body,

  • to notify to the ETSI Director-General all potential IPRs that their company may own, by means of the IPR Information Statement and the Licensing Declaration forms through the ETSI IPR online database application at Only under exceptional circumstances and if instructed by the ETSI Secretariat, paper declarations may be allowed using the forms provided by the ETSI Secretariat similar to the on-line forms.

Members are encouraged to make general IPR undertakings/declarations that they will make licenses available for all their IPRs under FRAND terms and conditions related to a specific standardization area and then, as soon as feasible, provide (or refine) detailed disclosures”.

This Call for IPRs is a notice to the TB/ISG member’s obligations regarding the disclosure of Essential IPRs in a timely fashion.

The meeting report shall clearly state that an IPR call has been made as well as any responses.

In addition, during the meeting a short reminder call for IPR disclosures should be made on:

  • the formal submission of a technical solution
  • the completion of the first stable draft of the standard
  • Working Group approval of a draft standard
  • TB/ISG approval of a draft standard.

Recording and reporting information on IPR

The Chair shall be careful to record in the Meeting report that an IPR reminder was issued and include details of responses. If no responses were given, then also this should be recorded.

If the Chair becomes aware of the existence of an Essential or potentially Essential IPR, the ETSI Legal Director shall be informed by the Chair.

The Chair should encourage the TB/ISG members to make general IPR undertakings/licensing declarations that they will make licenses available for all their IPRs under FRAND terms and conditions related to a specific standardization area and then, as soon as feasible, provide (or refine) detailed disclosures. Such declarations shall be made in the ETSI IPR database.

Copyrights in ETSI Deliverables

The Chair shall ensure that all technical proposals adopted by their TB/ISG are recorded in the Meeting report.
If copyright restrictions exist on the use of any technical proposals, the Chair shall ensure that these are also recorded in the Meeting Report and that the ETSI Secretariat is informed.
If, in exceptional circumstances, the use of copyrighted third- party material (text/figures) cannot be avoided, reproduction in ETSI deliverables will require the author’s authorization and the copyrighted material shall be indicated by the symbol © and with proper acknowledgment of its owner.
The Chair should instruct the Rapporteur to obtain the author’s authorization using the template available from the editHelp web page.

Chair’s Responsibilities on Antitrust Compliance

As stated in Clause 1.5 of the Technical Working Procedures, when preparing each meeting the Chair and/or the Secretary, should give attention to the agenda and ensure it is distributed and/or made available to all participants prior to the meeting.

The meeting shall follow the prepared agenda and only matters included on the agenda can be discussed. Revisions to the agenda can be made during the meeting, by following the principles of decision making as outlined in the ETSI TWPs Clause 1.7.1.

The Chair should take care that the ETSI Guidelines for Antitrust Compliance are strictly observed by reminding orally or by writing the following:

“The attention of the members of this Technical Body/ISG is drawn to the fact that ETSI activities are subject to all applicable antitrust and competition laws and that compliance with said laws is therefore required of any participant of this meeting including the Chair and Vice Chair(s). The leadership shall conduct the present meeting with impartiality. In case of questions, it is recommended that you contact your legal counsel”.

Managing discussions

Discussions, communications or any other exchange of information in or on the edge of all ETSI meetings (e.g.: informal discussions, social gatherings, corridor talks etc.) as well as during any activity in ETSI may never have as their subject matter topics that are prohibited by competition law.

If a delegate or the Chair becomes aware of a discussion, communication or exchange of information that appears to lead to restriction of competition of any kind, the delegate should raise the issue, seek to end or separate from this discussion, communication or exchange of information.

References: Clause C.4.1 of the Guidelines for Antitrust Compliance.

Chair’s Responsibilities on Confidentiality

All documents and information provided in or for TB/ISG meetings shall be considered non-confidential unless the information (in written form AND is identified AND accepted by the Chair) has been labelled as confidential.

Confidential information that has been incorporated in a Standard or Technical Specification is automatically regarded as non-confidential from the moment of publication.

If the Chair becomes aware that confidential information has been disclosed in breach of a confidential disclosure agreement to which ETSI is a party, the Chair shall immediately inform the Secretariat.

External cooperation with ETSI Partners

Overview of partnership agreements

When there is a need for the establishment of a partnership agreement, ETSI TBs/SCs and ISGs are required to refer to the ETSI partnership policy framework and the Partnership Engagement Process (PEP) as described in the TWPs Clause 1.8.1. The TB Chair will be accompanied by the ETSI Secretariat and the Partnership team.

The TB or ISG Chair should ensure that they are aware of all the relevant partnership engagements with other organisations and that they abide by the partnership engagements for the work of the TBs and ISGs they are responsible for.

There are three different types of partnership agreements depending on partnership engagement:

Engagement Main Focus ETSI TWPs
Examples, comments
Type 1
Letter of Intent (LoI)
Initial contact, get to know each other.

Type 2
Memorandum of Understanding
[Partner shall be a legal entity] | - Political
- Marketing
- Technical

Type 3
Co-operation Agreement (CA)

[Partner shall be a legal entity and an IPR Policy Check performed to determine the compatibility of the Partner’s IPR Policy with ETSI’s]

- Political
- Marketing
- Technical

  • Detailed information on types of partnership agreements can be found in TWPs, Clause 1.8.1.
  • Detailed information on Basic Co-operation Agreement between CEN, CENELEC and ETSI and the description of 5 modes of cooperation is given in Annex P of the TWP.
  • Full overview of the ETSI Partnership Engagements can be found in TWPs, Annex R.
  • The full list of agreements can be found at ETSI Partnership portfolio page on ETSI portal: see Section 6.2.2 below.

ETSI Cooperation Agreements and Supplements

General Information

Whenever there is a Cooperation Agreement signed with a supplement, TB and ISG Chairs are encouraged to use the maximum of the agreement and its supplements.

A Cooperation Agreement may include a PAS Supplement, a Working Supplement or a Materials Supplement for the following purposes:

  • PAS Supplement enables an external organisation to submit its publicly available specifications to ETSI for adoption.
  • Working Supplement allows for the creation of a common work item to produce a joint deliverable
  • Materials Supplement allows for incorporation of text and graphics in ETSI deliverables.

PAS (Publicly Available Specification) Process

The ETSI PAS Process enables an ETSI Partner who has signed a cooperation agreement and a PAS Supplement to submit one or more of its Publicly Available Specifications for adoption by ETSI as an ETSI Technical Specification (TS) or as an ETSI Technical Report (TR). The ETSI TB identified by the ETSI Board will be the host of the PAS review and will approve the PAS as a TR or TS following the normal ETSI approval procedure.

The attention of the TB Chair is drawn to the need to create the corresponding Work Item in the relevant TB immediately after the Board decision to allocate the PAS to this TB and before starting any work.

A PAS Process Guide is available for download describing the process and its benefits.

Further information is available on the ETSI website: Partnership

Participation of an ETSI Partner representative in ETSI meetings

Most of the Partnership Agreements allow for cooperative interworking between relevant ETSI TBs/ISGs and the groups of the other party. This is usually limited to one partnership representative per ETSI TB/ISG depending on the work topic. The work topic will be identified in the summary of the agreement as well as in an annex describing the working areas.

Partnership information is available at:

This attendance rule also applies to ETSI’s participation in the partner’s technical bodies.

It shall also be noted that participation by a Partner’s nominated observer in an ISG is subject to the signature of the ISG Participant’s Agreement, in accordance with ETSI TWPs, Clause 3.4.

Working with Observers and non-members

Participation of Observers and non-members in ETSI meetings

The conditions for participation of Observers and non- members in ETSI meetings are described in Clauses 2.1 and 2.2 of the present Guide.

Liaison Statements when there is no Partnership Agreement

Simple liaison statements between ETSI TBs/ISGs and external bodies are to be encouraged as a first step. If such liaisons reach the point where the two bodies concerned are going to exchange technical documents, then the need for a formal Partnership Agreement should be investigated.

Joint meeting with an organisation that has no Partnership Agreement with ETSI

It is possible for an ETSI TB/ISG to exchange information and even hold a joint meeting with an organisation that has no Partnership Agreement with ETSI. This typically occurs during the phase where ETSI and the other organisation are getting to know each other and before the need for a formal Partnership is identified.

If a meeting between the two organisations needs to take place, a set of basic rules and principles must be followed to comply with the ETSI TWPs and to remain in a safe zone from the legal standpoint. e.g., no TB/ISG working document can be discussed in such meeting unless it is publicly available.

Meeting type:

  • The meeting cannot be a formal meeting of the TB/ISG or of the other organisation. ETSI cannot impose its rules on another organisation and likewise, another organisation cannot impose its rules on ETSI. Therefore, the meeting should be organised as a “Workshop” under the umbrella of the identified TB/ISG.
  • If any new content is created during the TB/ISG workshop, the copyright for that content is jointly owned by ETSI and the non- partner organisation.
  • The principle of the ISG meeting participation fee shall not be applied to workshops organized between an ISG and a non- partner organisation.

Cooperation between ETSI TBs/SCs and ISGs

The attention of the TB/SC and ISG Chairs is drawn to the details of cooperation in between ETSI TBs, TBs and ISGs, TBs and SCs and in between ISGs.

Typically, interactions between different TBs and ISGs are based on Liaison Statements (LS) exchange, Liaison Officers reporting and joint meetings.

The table below considers different scenarios of collaboration.

Cooperation between TBs and ISGs Type of cooperation
In between TBs/SCs - Liaison officer
- Liaison statement
- Joint meeting(s)
TBs/SCs with ISGs
In between ISGs
- Liaison officer from one ISG or TB/SC can attend another ISG meeting only if his/her organisation signed the ISG agreement

- Liaison statements
- Joint meeting – see Section 6.3.3 above (meetings with non-Partners)

ETSI Chair’s Responsibilities – Operational Coordination Group (OCG)


The OCG acts as a focal point and a forum for co-ordination of and between the Technical Committees (TCs), ETSI Projects (EPs), ISGs, Special Committees (SCs), Coordination Groups (CGs) and the ETSI Secretariat.

The OCG provides an opportunity for Chairs and ETSI representatives to CGs initiated by external bodies to exchange information and experiences; and to discuss any issues prior to formal resolution of substantial objections in the Board and respond to Board requests for information.

The OCG also makes recommendations to the Board on the allocation of resources for STFs and on the proposed technical testing roadmap and priorities for TTFs. The OCG is also involved in the endorsement of MoU’s, Cooperation Agreements, and the processing of PAS Supplements.

It shall resolve, as far as possible, any duplication of effort or conflict of technical views between the TBs/ISGs to reinforce co-operation between the Technical Organisation, the ISGs and the CGs.

A TB/ISG Chair will be periodically requested to report to the OCG on the progress, issues and topics for decision.

The Chair’s role in the OCG

OCG meetings are open to TB, SC, EP and ISG Chairs, and meetings are called as required to fulfil the duties as mentioned above.

Periodically (typically every two years), each TB, SC, EP and ISG Chair is required to present progress reports to the Board meeting.

STF/TTF Management and Chair’s responsibilities


An active contribution of the TB/ISG/SC Chair is required in the phases listed below.

Drafting the Terms of Reference

The Chair makes sure that a new Special Task Force or Testing Task Force (STF/TTF) proposal, including the related Work Items, is supported by at least four (4) ETSI members and approved by the Reference Body, irrespective of the funding source.

STF/TTF Work plan

The work plan included in the STF/TTF Terms of Reference (ToR) is established by the Reference Body Chair, in consultation with the ETSI Secretariat, and contains the following elements:

  • latest schedule for the availability of the base documents
  • milestones and reporting schedule
  • deliverables schedule
  • tasks and resources assigned to the service providers
  • provisional travel plan for the participation of service providers’ personnel to meetings and events.

Submission of STF/TTF proposal

Submission of STF proposal funded by ETSI

STF proposals under the ETSI budget can be submitted in the two allocation steps, in October/November and in May/June (urgent requests only) time periods.

Submission of STF proposal funded by EC/EFTA

Since April 2021, the EC changed the process for STF proposals funded by EC/EFTA and established a new Agency called the European Innovation Council and SMEs Executive Agency (EISMEA).

The STF proposals are first assessed by EC (DG GROW and/or any relevant DG). To be eligible to EC/EFTA funded, the STF proposals shall:

  • be linked to a Commission priority, Commission strategy, EU legislation or other documents (e.g., the ICT Rolling Plan or the Annual Union Work Programme); and
  • meet the Single Market Programme (SMP) objectives; and
  • state the expected deliverables/outcomes; and
  • mention the objective and verifiable criteria that will allow the EC to assess that the above deliverables/outcomes have been effectively met.

If the above criteria are met, EISMEA then evaluates the STF proposals with the following criteria:

  • Relevance
  • Quality — Project design and implementation
  • Quality — Project team and cooperation arrangements
  • Impact.

For each criterion, there is a threshold, and each threshold shall be met to receive a positive assessment from EISMEA. and with proper acknowledgement of its owner.

Submission of TTF proposal

The TB/ISG/SC Chair is to liaise with the CTI Director at each step of TTF proposal submission.

The initial TTF ToR should be sent to the CTI Director before the date indicated in the TTF Process Calendar, so it can be incorporated into the following year’s Technical Roadmap.

The TB/ISG/SC Chair is to present and defend the work behind the TTF proposal at the September Board/OCG meeting.

Recruitment of the experts

Applications from ETSI members active in the TB/ISG/SC are encouraged. The STF/TTF Manager (ETSI Secretariat) and the Chair should assess the applications and draw up a short list of candidates.

To avoid a conflict of interest in the selection of service providers, the Reference Body Chair/Vice-Chair(s) and the Chair of the Working Group directly concerned by the STF/ TTF activity and who belong to an organis ation that has an interest in applying for selection as a service provider to a funded STF/TTF, shall declare this to the Board and subsequently be excluded from all discussions and decisions related to the selection of the service providers.

Preparatory Meeting (Experts’ interview)

The TB/ISG/SC Chair should attend the preparatory meeting with the selected experts, appoint the STF/TTF Leader, and decide on the draft Work Plan and allocation of resources. This should be done in coordination with the ETSI STF/TTF Manager & Technical Officer and, in the case of a TTF, the CTI Director.

Monitoring STF/TTF progress

The Chair is expected to provide technical guidance. The STF/TTF leader is appointed by the Director-General in consultation with the relevant TB/ISG Chair. The STF/TTF leader acts as the interface with the Director-General for management of the STF/TTF, with the service provider(s) for coordination of the project and with the TB/ISG/SC Chair for technical control. It is recommended that a Steering Group (SG) is set up. It is essential to ensure the timely approval of the STF/TTF deliverables by the TB/ISG/SC.

STF/TTF Reporting

The Chair approves the STF/TTF Progress Reports which confirm the achievement of the intermediate milestones against which the experts’ companies will be paid by ETSI Director-General.

Whenever possible, the reports should be reviewed and endorsed by members of relevant TB/ISG/SC, before the approval by the TB/ISG/SC Chair.

Closing the STF/TTF

Upon completion of the STF/TTF work, the TB/ISG/SC Chair shall ensure that feedback is provided to the Director- General on the STF/TTF work.

EC cooperation

The ETSI Director-General (or a nominated substitute) represents ETSI within the relevant committees of the EC and EFTA concerning advisory or regulatory standardization issues.

The TB/ISG Chair should be aware of all the relevant liaisons between ETSI and the EC.

The TB/ISG Chair should also consider/verify relevant contributions of the TB/ISG to EC/EFTA Annual Union Work Programme (AUWP), the Rolling Plan for ICT Standardisation and any other EU policy.

The main goal of contribution to AUWP is to indicate what needs to be mandated by the EC for ESOs (AUWP targets ESOs only). AUWP is adopted after having conducted EC consultation with relevant stakeholders: ESOs, Member States and Annex III organisations (see Regulation 1025/2012). In many cases, a pre-condition for a Standardisation Request is an item in the AUWP. On the other hand, AUWP is not binding for the EC.

Standardisation actions identified in Rolling plan for ICT Standardisation are complementary to other instruments, in particular the Annual Union Work Programme (AUWP).

Normally, it is for the ETSI Secretariat to coordinate the response to the AUWP, the Rolling Plan for ICT Standardisation and any other EU policy. Information is shared among the ETSI members through the ETSI OCG and relevant ETSI BOARD meetings.

ETSI working tools

Most of ETSI’s work is carried out by electronic means - by email exploder lists and via the ETSI portal.

Guidance is available from the portal wiki help pages including FAQs.

  • An ETSI on-line (EOL) account is required to access most areas such as the ETSI portal.
  • The ETSI Work Programme (EWP) contains all the technical activities and work items of ETSI committees and ISGs and enables the download of ETSI publications via a search engine.
  • Remote Consensus is the ETSI online tool to collect comments and measure consensus for contributions during a given period as opposed to during a face-to-face meeting.
  • The TB Decision Support application is designed to help the Technical Bodies/ISGs in their decision-making processes. Several types of formal Voting procedures (as opposed to consensus gathering) are predefined, including the vote for the approval of a draft, selecting a technology and electing officials.
  • The e-Approval application is the means for voting on draft ETSI Standards, ETSI Guides, ETSI European Standards and ETSI Harmonized European Standards. The consultation of comments and/or results of votes on such documents is also possible.
