1. HL-LHC Standards and Best Practices Workshop (11-13 June 2014)

2. 2 Which standard do you use for welding assembly for your own in-house production and for your partners and sub-contractors? International standards (ISO) National standards In-house internal specifications (ad hoc requirements) Combination of International or National standards + in-house specifications Welding personnel Qualification of the personnel in charge of welding activities in your institute Identify in your institute a reference person who owns a deep experience in welding standards and welding specifications Welding fabrication facilities Do you have fabrication in-house? Technologies? Do you have a network of subcontractors? How they are qualified? Quality control of welds Your quality assurance system is based on which standard? Do you have NDT in-house facilities? If you do not have a quality management system, how are you organised?

3. HL-LHC Standards and Best Practices Workshop (11-13 June 2014) 3 Main outcomes

4. HL-LHC Standards and Best Practices Workshop (11-13 June 2014) 4 US HL-LHC “Ruben Carcagno” Fabrication in house in compliance with ASME but not coded fabrication. Reference persons for welding fabrication issues: FERMILAB: Jaime BLOWERS BROOKHAVEN: Al FARLAND Qualified subcontractors, U stamp certified. Specific adherence to US National Codes. Internal Engineering Notes exits for: 5031 - Pressure Vessels 5031.1 - Piping Systems 5031.5 - Low Pressure Vessels 5033 - Vacuum Vessels 5033.1 - Vacuum Windows http://esh.fnal.gov/xms/ESHQ-Manuals/FESHM Recent experience with DESY, fabrication according to ASME followed by a CE marking, the intervention of a notified body was mandatory. Clear directive from CERN for the essential Safety Requirements is needed, i.e PED compliance?

5. HL-LHC Standards and Best Practices Workshop (11-13 June 2014) 5 KEK, Tsukuba Japan “Dr. KIMURA, Nobuhiro” No welding fabrication in house. Reference persons for welding fabrication issues: Dr. KIMURA Nobuhiro Design in house according to Japan Industrial Standards (JIS). Fabrication by qualified industry. KEK considers that JIS can comply with ISO requirements with some discrepancies. Clear directive form CERN for the essential Safety Requirements is needed, i.e. PED compliance, Do CERN require CE marking?

6. HL-LHC Standards and Best Practices Workshop (11-13 June 2014) 6 CERN many colleagues Clear directive from CERN for the essential Safety Requirements is needed, i.e. PED compliance? Best practice for vacuum components “design and fabrication” to be worked out. In case of components exposed to radiation and pressure, specific code like RCC-MR might be applicable.

7. HL-LHC Standards and Best Practices Workshop (11-13 June 2014) 7 Lawrence Berkeley National Laboratory, Daniel Cheng INFN Milano, Giovanni Volpini CIEMAT, Jesus A. García Matos STFC Daresbury laboratory, Shrikant Pattalwar European laboratories have more facilities to fulfill with the essential requirements of the PED when needed Other laboratories participating in the round table:

8. HL-LHC Standards and Best Practices Workshop (11-13 June 2014) 8 Conclusion Clear roadmap shall be defined: Essential safety requirements, PED compliance or more; Compliance between pressure equipment construction codes to be clarified, notified bodies shall be involved? Do CERN require CE marking? Equipment exposed to pressure/radiation: specific construction codes to be followed “RCC-MR”? Design approval process to be defined: e.g. Vacuum, Surfaces and Coatings (VSC) group to be consulted, Working group for best practises in vacuum chambers design and fabrication to be launched. For equipment hors category, Sound Engineering Practice (SEP) to be applied. A working group is needed to define SEP according to CERN needs. Other working groups? yes
