Electrolyzers/Fuel Cells

ISO 6469-1:2009 specifies requirements for the on-board rechargeable energy storage systems (RESS) of electrically propelled road vehicles, including battery-electric vehicles (BEVs), fuel-cell vehicles (FCVs) and hybrid electric vehicles (HEVs), for the protection of persons inside and outside the vehicle and the vehicle environment. Flywheels are not included in the scope of ISO 6469-1:2009.
ISO 6469-1:2009 does not apply to RESS in motorcycles and vehicles not primarily intended as road vehicles, such as material handling trucks or fork-lift trucks.

Provides information on the physical and chemical properties of hydrogen and proper handling and use. It is intended to provide background information for personnel involved in the manufacture, distribution, and use of hydrogen. Additional technical information can be obtained from hydrogen gas manufacturers.

This publication presents design guidelines for hydrogen vent systems used in gaseous and liquid hydrogen systems at user sites and provides recommendations for safe operation of these vents. It begins at the discharge port of safety devices and other components that control the release of hydrogen and ends at the point where hydrogen concentration in the atmosphere is below the lower flammable limits. It also provides information on the production, transportation, handling, and storage of compressed hydrogen, cryogenic liquid hydrogen, and related products.

Purpose of this Guidebook: This guidebook provides information on the requirements to achieve and renew a Compressed Natural Gas (CNG) Cylinder and Fuel System Inspector personnel certification.
About this Certification: The CNG Cylinder and Fuel System Inspector Certification was developed to meet the needs of fleets of all sizes that use safe, cleaner-burning natural gas to power their vehicles.
