IEC/TC 105Work programme

11. R&D Demonstration Commercialization Foster cooperation, guide technical work and accelerate the development of products by reducing the time required to get a new design into production Assure safety of products and installations Needed to allow product certification and global trade Improve user and customer confidence in the products 2. Benefits of RC&S HarmonizationRC&S activities can help facilitate:

12. 2. Benefits of Harmonization • Provide a common language between buyers and sellers • Increase productivity and efficiency in manufacturing (reduce the variety of products) • Reduction of capital investment in inventory, warehouse and special equipment

13. 3. Harmonization Organizations • Global bodies such as UN/ECE, ISO, IEC are working towards global harmonization • The member countries of IPHE recognize that common RC&S are required to accelerate the cost-effective transition to a global hydrogen economy • The HarmonHy project also fosters the harmonization of RC&S • The Global Cooperation Group (GCG) is actively working with existing international organizations to facilitate harmonization

14. Global Links Regulatory bodies International SDOs Other venues: ISO Roundtable IPHE UN ECE ISO/IEC ILC Inland Transport Committee ISO/TC197 H2 Technologies Sustainable Energy Cooperation agreement between TC197 and TC22, TC58 & IEC/TC105 IEA WP.29 WP.15 GCG Harmonization of Vehicle Regulations Transport of Dangerous Goods ISO/TC22 GRPE EC Road Vehicles HarmonHy GRPE HFCV Informal Group ISO/TC58 HySafe IEC/TC105 Gas cylinders Development of HFC Vehicle GTR Fuel cell Technologies

15. 4. How HySafe can help… • In order to develop international RC&S that are based on the consolidated results of science, technology and experience, there is a need to get an international consensus on topics such as: • Hydrogen release and dispersion in a number of environments • Thermal and pressure effects from hydrogen fires and explosions • Mitigation techniques • Risk assessment • Hazardous Zones – Electrical Classification Distances • Clearance Distances for Venting of Hydrogen Storage

16. 4. How HySafe can help… • The experts involved in hydrogen safety should get involved in ISO/IEC. Their participation will ensure: • Their work is made available to the international RC&S community • Their work is connected to the needs of the international RC&S community • Their work is presented in a format acceptable to the international RC&S community • Assumptions are clearly defined; • Tools used are identified; • Means have been taken to validate the results.
