CSA America HGV4.5

Priority and Sequencing Equipment for Gaseous Hydrogen Dispensing Systems

Scope

Status

This standard applies to priority and sequencing equipment which are part of a gaseous hydrogen vehicle fueling system. This standard contains safety requirements for the design, manufacture and testing of the priority and sequencing systems for gaseous hydrogen dispensers which are designed primarily to provide compressed hydrogen for vehicle fueling stations. This standard does not apply to the pressure swing adsorber sequencing panel or the gas dryer sequencing panel.

Published as a CSA standard in December 2008. Revised and published as an ANSI standard in July 2012. Temporarily withdrawn, but re-published as a CSA standard in April 2013. Approved as an ANSI standard. Withdrawn again.

2022. A seed document has been prepared for the process of reinstating this standard.
