This International Standard specifies minimum requirements for light-weight refillable gas cylinders intended only for the on-board storage of high pressure compressed natural gas as a fuel for automotive vehicles to which the cylinders are to be fixed. The service conditions do not cover external loadings that can arise from vehicle collisions, etc.
This International Standard covers cylinders of any seamless steel, seamless aluminium alloy or nonmetallic material construction, using any design or method or manufacture suitable for the specified service conditions. This International Standard does not cover cylinders of stainless steel. Although this standard uses 200 bar as a reference working pressure, other working pressures can be used.
Cylinders covered by this International Standard are designed Type 1, Type 2, Type 3 and Type 4.
