Road vehicles — Dimethyl Ether (DME) fuel system components — Part 9: Pressure relief device (PRD)
This document specifies definitions of and general requirements to a pressure relief device for limiting internal pressure of dimethyl (DME) fuel containers intended for use on the types of motor vehicles as defined in ISO 3833. It also provides general design principles and specifies requirements for instructions and marking. This document is applicable to vehicles using gaseous fuels in accordance with ISO 16861. It is not applicable to the following: a) fuel containers for any application other than as noted above; b) stationary, ship, railroad vehicle or aircraft DME engine installations; c) fuel container mounting hardware; d) electronic fuel management. NOTE 1 It is recognized that miscellaneous component properties not specifically addressed herein can be examined for compliance with the criteria of any applicable part of the ISO 20760 series, including subjecting the component to appropriate functional tests. NOTE 2 All pressures referred to in this document are gauge pressures unless otherwise specified.
