Cen Consists Of:

CEN activities in relation to the Pressure Equipment Sector Warsaw, June 24, 25 & 26, 2004 Nouredine Hakimi CEN Programme Manager Content Some important horizontal decisions taken at CEN level The Pressure Equipment Advisory Nucleus The work programme and status of standards The promotion of Pressure Equipment standards Conclusion Some important horizontal decisions taken at CEN level Mr Lars Flink, the new chairman of the CEN Board, outlined the challenges facing CEN in the next three years: 3-year timeframe for the development of standards: the successful implementation of this action; Construction Products directive: a significant increase in the number of standards adopted (e.g. target of 300 harmonized standards by the end of 2004); Enlargement of CEN: participation of all CEN Member bodies in the technical work. Technical work in the enlarged CEN (Resolution BT 10/2004) BT created a group (BT/CAG 172 Technical work in

enlarged CEN) to advise the Chairman on ways to facilitate the participation of the National Standards Bodies in the technical work, at all levels. Global relevance of standards (Resolution BT 17/2004) BT noted that BT/WG 152 Global relevance in standards is developing guidance to CEN technical committees on the implications of global relevance. The Pressure Equipment Advisory Nucleus:PE-AN The pressure Equipment Advisory Nucleus is a group reporting to the CEN Technical board. There are 16 members (NSBs, EC, Notified Bodies, Users, Manufacturers, CMC,..) The role of the PE-AN is to manage the sector activities The PE-AN has plenary meetings 2 to 3 times a year. Next meeting: 20 October 2004 PE-AN The PE-AN issues recommendations that are handles by the CEN Programme manager. This could lead for example to: BT decisions Messages to CEN/TCs The PE-AN could be addressed to answer to specific concerns related to the sector

Specific principles in the pressure sector The pressure equipment standards are classified into two categories Type 1 standards (Cited in the Official Journal) Type 2 standards (not cited ) Classification of Standards: Type 1 standards Provide a technical solution to [fully] achieve one or more specific PED Essential Safety Requirements either by itself or by calling up other references (see guideline 10.5). It can be a product standard (i.e. a standard dealing with items of pressure equipment or assemblies) or a standard dealing with materials, procedures for permanent joining, approval of NDT personnel etc. Classification of Standards: Type 2 standards Provide useful elements that contribute to the fulfilment of ESR(s) cannot alone give presumption of conformity to these ESRs. Examples: NDT test methods, general principles, terminology.

Type 2 standards are likely to be used as normative references in type 1 standards The work programme and status of standards European Standards Some 24 CEN and 9 ECISS Technical Committees relate to the PED 287 harmonized standards 587 supporting standards Harmonized standards by TCs Technical Committee Title # of standards TC 23 Transportable gas cylinders TC 54 Unfired pressure vessels TC 57 Central heating boilers

- answering queries raised by users. The Promotion of Pressure Equipment Standards CEN does not sell standards but encourages their use The promotion of standards is to the benefit of all, especially the NSBs Ways of promoting are: Writing case studies on the success of manufactures using ENs Being present at important conferences (speakers, booths) Publishing articles on important standards Organising workshops/conferences Developing help desks Promotion of standards outside Europe: Visibility Fund The European Commission Services Visibility Fund for co-financing projects aimed at the promotion of standards outside Europe has been used in 2004 for four projects : Presentation of the Design Criteria of EN 13445 During the 57th Annual Assembly of the International Institute of Welding (IIW),Osaka (Japan) 11-16 July 2004; This includes 16 presentations from European experts;

Presentation of the European position on sealing technology, creep damage and repairs at the Pressure Vessel Research Council Meetings of April 5-8, 2004 in Savannah, Georgia, USA.; by Guy Baylac; Presentation of the results of the Comparative Study on Pressure Equipment Standards at the ASME PVP Conference 2004, July 25 29, San Diego, CA, USA, by Prof. Josef Zeman TUW (Vienna, Austria); Lectures at the Pressure Vessel Association of China, and the East China University of Science & Technology in September 2004, by John Darlaston Conclusions The CEN work programme supporting the PED has well progressed Some gaps should be filled: Harmonized standards for Cast Iron are still an omission Develop copper and aluminium material standards for pressure purposes CEN looks forward for the Completion of mandated programme Major product standards are available and need to be used more by industry Extension of EN 13445 to:

The creep range Aluminium Design by experiments others Is ongoing (all will be completed by 2006) CEN looks to further improve competitiveness of ENs And to promote EN standards Useful Websites PED Text and Guidelines (hyperlinked) http://ped.eurodyn.com www.europa.eu.int/comm/enterprise/newapproach/ standardization/harmstds/reflist/equippre.html CEN Website http://www.cenorm.be CEN contact person for pressure equipment: [email protected]
