Assessment Update

IECEX Scheme updated for Hydrogen Fuel Dispensers

Happy 2023! I thought as it was anew year I would take a break from updating everyone on the every changing UKCA Requirements and look at a few other scheme and Standards updates.

The IECEx Certified Equipment Scheme have published OD 290 - Harmonized procedures for IECEx certification of equipment, components and systems associated with the production, dispensing and use of gaseous hydrogen.

 IECEx ExCBs and ExTLs such as ExVeritas are required to apply these publications to all new applications for certification of Hydrogen dispensing equipment and dispensing units, treated as assemblies according to IEC TS 60079-46The new operational document outlines tests to be conducted when assessinggaseous hydrogen dispensers, they include:
• Leakage test
• Impact test
• Dispenser shutdown test
• Hose rupture
• Hose breakaway test
• Electrostatic discharge test
• Earth (ground) continuity
• Dielectric voltage-withstand test
• IP Tests 
 

IEC TS 60079-46 is for the certication of ‘assemblies’ and can be applied to any combination of certified equipment from diesel skids to pump sets. Assembly Certification gives end users confidence that the package they have had delivered are assessed by a 3rd party and simplifies the marking of the overall package. IEC TS 60079-46 is required for IECEX Assembly Certification but can also be used as the basis for ATEX and UKCA Approval if requested.

Purge and Intrinsic Safety Standards Update

Just to note there have been major updates to the Purge and Pressurization Standard and the new Intrinsic Safety Standard (which has just been published). These are very significant updates with approximately 40 major technical changes in each so will need to be considered carefully by manufacturers who use these concepts.
