The CERN Standardisation Committee (CSC) connects CERN technical communities with CERN Stores. CSC defines products to reference, their technical specifications, and the expected quality standards. Its mandate includes maximizing cost-effectiveness, mitigating supply risks, and broadening sourcing opportunities in underrepresented CERN Member States while supporting accelerator and experiment needs.

It operates through three technical sub-committees with the following outstanding results in 2024:

• Vacuum Equipment which reviewed technical specifications and drawings of metal seals, pumps and flanges. Key outcomes: A PunchOut catalogue for ISO-KF & ISO-K connecting components and a new contract for small right-angle valves.
• Metal Raw Materials which updated key technical specifications for stainless steel, titanium alloy, and Cu-OFE used to manufacture components for ultra-high vacuum (UHV), cryogenics, magnets, and irradiation applications. It allowed securing procurements totaling over 800 tons of raw materials for ongoing and future projects!
• Cables & Connectors which overseen specification and procurement of cables with fire & radiation behaviors for LS3. A new EDMS structure has been implemented for traceability reasons. A comprehensive Quality Assurance plan has been agreed upon, including new Quality Controls performed at CERN Stores.

The achievements of the CSC and its technical subcommittees in recent years have demonstrated the value of this expert-driven forum. With major projects ahead, an evolving market landscape, and ever-growing quality requirements, the CSC has a bright future ahead of it!
