BS ISO 20766-14:2022

What is ISO 20766‑14 - LPG vehicle pressure regulator about?

The pressure regulator ensures gas flow to the engine. ISO 20766 is an International Standard series on road vehicle LPG fuel systems. ISO 20766‑14 specifies general information regarding the vaporizer/pressure regulator component of LPG fuel, intended for use on the types of motor vehicles.

ISO 20766‑14 is the 14th part of the multi-series and specifies general requirements for the vaporizer/pressure regulator, a component of liquefied petroleum gas fuel, intended for use on the types of motor vehicles as defined in ISO 3833.

ISO 20766‑14 is applicable to vehicles (mono-fuel, bi-fuel, or dual-fuel applications) using gaseous fuels in accordance with ISO 9162.

All references to pressure in ISO 20766‑14 are considered gauge pressures unless otherwise specified.

ISO 20766‑14 applies to devices that have a service pressure in the range of 110 kPa (butane rich at 20 °C) and 840 kPa (propane at 20 °C), hereinafter referred to in ISO 20766‑14. Other service pressures can be accommodated by adjusting the pressure by the appropriate factor (ratio).

Note: ISO 20766‑14 is not applicable to the following:

• Fuel containers
• Stationary gas engines
• Container mounting hardware
• Electronic fuel management
• Refuelling receptacles

Who is ISO 20766‑14 - LPG vehicle pressure regulator for?

ISO 20766‑14 on LPG vehicle pressure regulator is useful for:

• Manufacturers of LPG fuelled vehicles
• Product design engineers / innovation teams
• Quality control personnel
• Road vehicle engineers
• Mechanical engineers
• LPG suppliers
• Manufacturers of vehicle components
• Safety and accident prevention authorities

Why should you use ISO 20766‑14 - LPG vehicle pressure regulator?

The main function of the regulator is to control the flow of gas. ISO 20766-14 provides general design principles and specifies requirements for instructions and marking of LPG pressure regulators.

ISO 20766-14 provides manufacturers with tools to improve their product by outlining tests that protect the device from leakage, perform continued operations, and ensure hydraulic strength by describing the construction and assembly mechanism of the manual vaporizer/pressure regulator.

The test is required to ensure hydraulic strength, high and low temperature of the LPG flexible vaporizer/pressure regulator, the tensile strength and elongation of the rubber vaporizer/pressure regulator, permeability, bending test, impulse test, and gas-tightness.

Using ISO 20766‑14 guidelines, you can achieve a sustainable and high-quality vaporizer/pressure regulator that functions smoothly in adverse conditions.  With obedience and compliance to ISO 20766‑14, you can achieve precision in terms of product functionality.
