NZS ISO 19881:2024
Gaseous hydrogen − Land vehicle fuel containers
Standard specifies the material, design, manufacture, marking, and testing of serially produced, refillable containers intended only for the storage of compressed hydrogen
gas for land vehicle operation.
These containers:
(a) Are permanently attached to the vehicle; and
(b) Have up to 1000 litres’ water capacity; and
(c) Have a nominal working pressure that does not exceed 70 MPa.
The scope of this document is limited to fuel containers containing fuel-cell-grade hydrogen according to ISO 14687, Hydrogen fuel quality − Product specification for
fuel cell land vehicles, and Grade A or better hydrogen as per ISO 14687 for internal combustion engine land vehicles. This document also contains requirements for hydrogen fuel containers acceptable for use aboard light-duty vehicles, heavy-duty vehicles, and powered industrial trucks, such as forklifts and other material-handling vehicles.
The standard was prepared by the P3652 Hydrogen Standards Committee and is identical to and has been reproduced from ISO 19881:2018, Gaseous hydrogen – Land
vehicle fuel containers.
