What is ISO 12614‑19 about?
ISO 12614‑19 is part 19 of the multi-series standard on automatic valve which is a liquefied natural gas (LNG) fuel system component.
ISO 12614‑19 specifies tests and requirements for the automatic valve, a liquefied natural gas fuel system component intended for use on the types of motor vehicles defined in ISO 3833.
ISO 12614‑19 is applicable to vehicles using natural gas in accordance with ISO 15403‑1 (mono-fuel, bi-fuel or dual-fuel applications).
NOTE-
ISO 12614‑19 is not applicable to the following
- Fuel containers
- Stationary gas engines
- Container mounting hardware
- Electronic fuel management
- Refuelling receptacles
Who is ISO 12614‑19 for?
ISO 12614‑19 on automatic valve is applicable to:
- Manufacturers of LNG vehicles
- Manufacturers of automatic valve
- Vehicle regulatory authorities
- Vehicle repair shop
Why should you use ISO 12614‑19?
ISO 12614‑19 specifies guidelines for the construction of automatic valve. These guidelines include the materials to be used and the method for assembly of those materials. The guidelines will enable you to manufacture durable fuel system components.
ISO 12614‑19provides marking instructions on automatic valve. The markings help in identifying and tracing automatic valve.
ISO 12614‑19 provides a test to check the insulation resistance. With the help of the test, you can check for a potential failure of the insulation between the two-pin coil assembly and the metallic part of the automatic valve casing.
What’s changed since the last update?
BS ISO 12614‑19:2021 edition cancels and replaces the first edition (ISO 12614‑19:2017), which has been technically revised.
The main changes compared to the previous edition are as follows:
- Editorial changes
- Requirements the insulation resistance (6.5) and minimum opening voltage (6.6)
