What are the regulations for hydrogen storage cylinders?

For the past two decades, some regulations, codes and standards are issued for hydrogen storage cylinder, such as EC REGULATION 406 , UN GTR13 Phase 1 (GTR13-PH1) , CSA/ANSI HGV2 , GB/T 35544 , SAE J2579 , ISO 19881 and GB/T 42612 .

How to promote the application of hydrogen storage cylinder?

In order to promote the application of hydrogen storage cylinder, guide its design, manufacture, inspection and testing, a series of regulations, codes and standards have been issued. The Chinese national standard, GB/T 42612, for type IV hydrogen storage cylinders has also been issued.

What are the requirements for a hydrogen cylinder?

The basic requirements are: cylinder which is free from harmful surface defects. According to present knowledge, probable cause for the early failure of hydrogen cylinders is fatigue, accelerated by hydrogen embrittlement.

What is the purpose of a hydrogen fuel standard?

The purpose of this standard is to reduce deaths and injuries occurring from fires that result from hydrogen fuel leakage during vehicle operation and after motor vehicle crashes. S3. Application. This standard applies to each motor vehicle that uses compressed hydrogen gas as a fuel source to propel the vehicle. S4. Definitions.

Should hydrogen vehicle standards be harmonised with GTR No 13?

This proposed rule was developed in concert with efforts to harmonize hydrogen vehicle standards with international partners through the Global Technical Regulation (GTR) process, and if adopted, would harmonize the FMVSSs with GTR No. 13, Hydrogen and Fuel Cell Vehicles.

What are the performance requirements for a hydrogen fuel system?

To this end, it includes performance requirements for the hydrogen fuel system to mitigate hazards associated with hydrogen leakage and discharge from the fuel system, as well as post-crash restrictions on hydrogen leakage, concentration in enclosed spaces, container displacement, and fire.
