Manufacturing and engineering standards S. Atieh et al. HL-LHC Standards and Best Practices Workshop (11 -13 June 2014)

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? HL-LHC Standards and Best Practices Workshop (11 -13 June 2014) 2

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

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? HL-LHC Standards and Best Practices Workshop (11 -13 June 2014) 4

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? HL-LHC Standards and Best Practices Workshop (11 -13 June 2014) 5

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. HL-LHC Standards and Best Practices Workshop (11 -13 June 2014) 6

Other laboratories participating in the round table: 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 HL-LHC Standards and Best Practices Workshop (11 -13 June 2014) 7

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 HL-LHC Standards and Best Practices Workshop (11 -13 June 2014) 8
