    AI Overview
    ISO 11439:2013 is the international standard specifying minimum requirements for high-pressure, refillable CNG cylinders used in automotive vehicles. It covers CNG-1 (metal), CNG-2 (hoop-wrapped), CNG-3 (fully wrapped), and CNG-4 (non-metallic) types, generally designed for a 200 bar working pressure, ensuring safety and durability. 
    Key Aspects of ISO 11439 Standard: 
    • Scope: Applies to cylinders used for on-board storage of compressed natural gas as fuel. It does not cover stainless steel cylinders.
    • Design & Materials: Covers seamless steel, seamless aluminum alloy, and non-metallic materials.
    • Working Pressure: The standard uses 200 bar (
      20
      MPa
      ) as a reference, although other pressures can be accommodated.
    • Safety Testing: Requires rigorous testing, including pressure cycling (typically 1,000 cycles) and environmental tests (e.g., bonfires, acid tests).
    • Service Life: Cylinders are designed for a specific finite service life, which is marked on the cylinder.
    • Latest Updates (Amendment 1:2021): Covers updated test methods, design verification, and enhanced corrosion testing. 
    Cylinder Types Covered: 
    • CNG-1: Seamless metal (steel or aluminum).
    • CNG-2: Hoop-wrapped with composite material over a metal liner.
    • CNG-3: Fully wrapped with composite material over a metal liner.
    • CNG-4: Fully wrapped with composite material over a non-metallic liner. 
    Note: ISO 11439 is often used in conjunction with other standards, such as ECE R110, which provides further regulations for CNG components.

    What is the difference between Type 2 and Type 3 CNG cylinders?
    Type 3 gas cylinders feature a thin and lightweight aluminium liner, fully overwrapped with carbon composite. Type 3 cylinders offer significant weight savings over Type 2 cylinders (up to 30%). They can also be filled to higher pressures (up to 300 bar), so they can offer increased capacity for the same size cylinder.Sep 22, 2020

    Which type CNG cylinder is best?
    Type 1 and Type 2 CNG cylinders have superior filling efficiency (up to 80%) compared to other types due to their uniform metal structure. This allows for quicker refuelling, making them an excellent choice for vehicles and industrial applications. So, choose any of the cylinders based on their cost-effectiveness.Mar 17, 2025
