If a value for a measurement and a corresponding value in other units are stated, the first stated value is to be regarded as the requirement. The given corresponding value may be approximate. If a value for a measurement and a corresponding value in other units are both specified as a quoted marking requirement, the first stated unit, or both are to be provided.

c) CT3: container or assembly of non-axisymmetric shape within a conformable protective shell that is acting as a shield and directly assisting the pressure containing elements with containing gas pressure.

The conformable container types shall have an additional identifier that is used in combination with the container type. A conformable container  shall be designated based on the design as a Type 1  to Type 4 with the additional conformable type identifier. For example, a Type 4 CT2 container would be required to meet the criteria for a Type 4 container as well as the criteria specified for a CT2 container.
