Mechanical engineering - General 

This subsector comprises six CEN technical bodies

A considerable proportion of the deliverables are harmonized standards that give presumption of conformity to the safety requirements of the Machinery Directive 2006/42/EC and mainly because of this status, they are widely used by the industry, market surveillance or conformity assessments bodies.

Horizontal aspects related to safety of machinery in CEN are within the responsibility of:

CEN/TC 114 'Safety of machinery' produced standards and other documents on general principles for the safety of machinery, including terminology and methodology. Among its portfolio is EN ISO 12100:2010 'Safety of machinery - General principles for design - Risk assessment and risk reduction', which translated the requirements of the Directive on machinery (2006/42/EC) into a hazard-based approach. Nearly 100% of the standards published by CEN/TC 114 are developed in cooperation with ISO/TC 199, and most of them support the Directive on machinery (2006/42/EC).

CEN/TC 211 ‘Acoustics’ developed with ISO/TC SO/TC 43 ‘Acoustics’ and ISO/TC 43/SC 1 ‘Noise’ more than 80 standards which provide information and guidance to practitioners, scientists and authorities around Europe. These documents  pave the way to a higher quality of life resulting from lower noise exposure levels by reduction of the risk for hearing damage and annoyance due to noise for all humans in public, working and private environments.

CEN-CENELEC sector on machinery brings together about 50 technical bodies dealing with different types of machinery for use in agriculture, industrial manufacturing, mining, construction and by consumers (e.g. lifts, motor-operated electric tools etc.).

The CEN-CENELEC-ETSI Coordination Group on Smart Manufacturing (SMa-CG) coordinates and advises on the European standardization activities relating to new technologies in the field of manufacturing.

  • CEN-CENELEC position on revision of Outdoor Noise Directive 2000/14/EC (2018) (PDF format)
  • Machinery terminological database in 35 different languages (Sept 2012) (excel format)
    The purpose of this document is to provide a multilingual database with the terms given by ISO 12100:2010 (including, definitions linked to those 57 terms). The database is composed of the 57 terms defined by ISO 12100 in English, French and German, and the translation of these terms into 30 different languages, namely : Arabic,  Bulgarian,  Croatian,  Chinese,  Czech,  Danish,  Dutch,  Estonian,  Finnish,  Greek,  Hungarian, Icelandic,  Italian,  Japanese,  Korean,  Latvian,  Lithuanian,  Malay,  Norwegian,  Persian (or Farsi),  Polish,  Portuguese,  Romanian,  Russian,  Serbian,  Slovak,  Slovenian,  Spanish,  Swedish and Turkish.  Free columns are provided for Albanian and Macedonian. Any other language is of course welcome in the database. ISO 639-1:2002 is used for the identification of the languages. Each national member body is invited to verify the corresponding cells in the following table, to correct them if necessary or insert the translation if available. If not validated by the national member bodies, translations will be identified as ‘non-official’. A further column has been added to give a link to the corresponding definition provided by the ISO Concept Database (“ISO CDB link”).
  • EC Guide to the Machinery Directive 2006/42 (Edition 2.1 - July 2018) (pdf format)
  • ILO code of practice on Safety and Health in the Use of Machinery (pdf format)
  • CEN Guide 414: Safety of machinery - Rules for the drafting and presentation of safety standards (2017).  At this moment only the English and the German versions of the Guide are available.

Sector Forum and Coordination Group

A Sector Forum is a platform aiming at facilitating the exchange of information between the different stakeholders, both coordinating and identifying the standardization needs in a specific field.

CEN-CENELEC Sector Forum on Machinery Safety
The aims of the CEN-CENELEC Sector Forum on Machinery Safety are to:

• identify, coordinate and meet the sector needs as expressed within the CEN and CENELEC technical committees which deal with the standardization activities in the safety of machinery field;
• facilitate the exchange of information between the technical committees;
• provide solutions to the problems that are common across the sector and which arise during the standardization work;
• identify new issues and analyse latest trends affecting safety of machinery;
• interface with actions relevant for machinery that come from the European Commission/European Free Trade Association and the European Parliament;
• monitor and communicate the sectoral activities on machinery safety in CEN and CENELEC.
The structure of the CEN-CENELEC Sector Forum on Machinery Safety is the following:
• Sector Rapporteur (Dr G. Steiger - VDMA, DE)
• Safety of Machinery Advisory Nucleus (SMS AN)
• the wider sector at large, i.e. the community of sector partners

The Rapporteur represents the sector in the CEN and CENELEC Technical Boards.

The SMS AN is constituted and chaired by the Sector Rapporteur and comprises a balanced representation from the community of sector partners, including the European Commission, HAS Consultants, the representatives of the societal interests (e.g. ETUI) and the officers of the technical committees.

Meetings: The Safety of Machinery Sector Advisory Nucleus (SMS AN) meets up to twice a year to discuss important issues relevant for standardization in the field of machinery safety.
The CEN-CENELEC-ETSI Coordination Group on Smart Manufacturing (SMa-CG) was created in order to coordinate the European standardization activities relating to new technologies in the field of manufacturing. It is a joint group of CEN, CENELEC and ETSI which advises the CEN-CENELEC Technical Boards and the ETSI Board.

SMa-CG gathers CEN, CENELEC and ETSI members, theirs relevant Technical Bodies and groups and the European Commission. The European associations, initiatives, research projects as well as international organizations and initiatives are welcome to participate in specific meetings upon the agreement of the Chairman.

The SMa-CG meets a few times per year via physical and / or web-meetings. The next meeting is scheduled for 10 December 2020.

Chair: Dr Jens Gayko, VDE
Secretariat: Ms Katharina Sehnert, DIN
