What is ISO 12614‑2 about?
ISO 12614‑2 specifies the performance and general test methods of liquefied natural gas fuel system components, intended for use on the types of motor vehicles as defined in ISO 3833.
ISO 12614‑2 is also applicable to other LNG-fuelled motor vehicles as far as appropriate, until any specific norm is worked out for such a type of vehicle.
ISO 12614‑2 provides general design principles and specifies requirements for instructions and marking.
NOTE-
ISO 12614‑2 is not applicable to the following:
- Fuel containers
- Stationary gas engines
- Container mounting hardware
- Electronic fuel management
- Refueling receptacles
Who is ISO 12614‑2 for?
ISO 12614‑2 on performance and general test methods for liquefied natural gas (LNG) fuel system components is applicable to:
- Manufacturers of LNG vehicles
- Manufacturers of liquefied natural gas (LNG) fuel system components
- Vehicle regulatory authorities
- Vehicle repair shops
Why should you use ISO 12614‑2?
ISO 12614‑2 contains tests to check the safety and durability of liquefied natural gas (LNG) fuel system components. These tests include the bending moment, hydraulic strength, leakage and excess torque resistance. These tests will help you manufacture durable fuel system components.
ISO 12614‑2 provides a method to check the vibration resistance of the fuel system components. ISO 12614‑2 makes sure that all components with moving parts will remain undamaged and will continue to operate and meet the requirements of their leakage tests and hydrostatic strength test after vibration, carried out according to test procedure.
What’s changed since the last update?
BS ISO 12614‑2:2021 edition cancels and replaces the first edition (ISO 12614‑2:2014), which has been technically revised.
The main changes compared to the previous edition are as follows:
