[Current]Hydrogen generators using fuel processing technologies, Part 1: Safety (ISO 16110-1:2007, MOD)
This Standard adopts ISO 16110-1:2007 with modifications for Australia, which specifies requirements for packaged, self-contained or factory matched hydrogen generation systems with a capacity of less than 400 m3/h at 0 °C and 101,325 kPa, herein referred to as hydrogen generators, that convert an input fuel to a hydrogen-rich stream of composition and conditions suitable for the type of device using the hydrogen (e.g. a fuel cell power system or a hydrogen compression, storage and delivery system).
