Gas tubes are particularly important for high-power applications. ISO 20766 is an International Standard series on road vehicle LPG fuel systems. ISO 20766‑24 specifies general information regarding the gas tubes component of liquefied petroleum gas fuel, intended for use on the types of motor vehicles.
ISO 20766‑24 is the 24th part of the multi-series and specifies general requirements for the gas tube, a component of liquefied petroleum gas fuel, intended for use on the types of motor vehicles as defined in ISO 3833.
ISO 20766‑24 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 20766‑24 are considered gauge pressures unless otherwise specified.
ISO 20766‑24 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 20766‑24. Other service pressures can be accommodated by adjusting the pressure by the appropriate factor (ratio).
Note: ISO 20766‑24 is not applicable to the following:
ISO 20766‑24 on LPG vehicle gas tubes is useful for:
ISO 20766-24 provides general design principles and specifies requirements for instructions and marking for gas tubes of LPG fuelled vehicles. ISO 20766-24 describes the construction and assembly mechanism of manual gas tubes.
ISO 20766-24 provides manufacturers with tools to improve their product by outlining tests that protect the device from leakage, perform continued operations, and ensure hydraulic strength.
ISO 20766-24 discusses high and low-temperature of the LPG flexible-gas tubes, the tensile strength, elongation of the rubber gas tubes, permeability, bending test, impulse test, and gas-tightness.
Using ISO 20766-24 guidelines, you can achieve sustainable and high-quality gas tubes that function smoothly in adverse conditions. With obedience and compliance to ISO 20766‑24, you can achieve precision in terms of product functionality.
