|Standard number:||21/30404426 DC|
|Status:||Draft for Comment|
This standard 21/30404426 DC BS ISO 20766-21. Road vehicles. Liquefied petroleum gas (LPG) fuel system components is classified in these ICS categories:
- 43.060.40 Fuel systems
This part of ISO 20766-21 specifies general requirements and definitions of liquefied petroleum gas fuel component (pressure and/or temperature sensors), 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 part of ISO 20766-21 is applicable to vehicles (mono-fuel, bi-fuel or dual-fuel applications) using gaseous fuels in accordance with ISO 9162 . It is not applicable to the following:
stationary gas engines;
container mounting hardware;
electronic fuel management;
It is recognized that miscellaneous components not specifically addressed herein can be examined for compliance with the criteria of any applicable part of ISO 20766 , including testing to the appropriate functional tests.
All references to pressure in this document are considered gauge pressures unless otherwise specified.
This document applies to device which have a service pressure in the range of 110 kPa (Butane rich at 20 °C) and 840 kPa (Propane rich at 20 °C), hereinafter referred to in this document.
Other service pressures can be accommodated by adjusting the pressure by the appropriate factor (ratio).
