Which of the following must be printed on the nameplate of a CNG container?

The nameplate of a CNG container must include the dish radius of the heads because this specification provides critical information about the geometry and design of the container. The dish radius pertains to the curvature of the heads (the end sections) of the cylinder, which is essential for determining the structural integrity and pressure capabilities of the container. Knowing the dish radius helps ensure that the container is manufactured and operated safely under the pressures associated with compressed natural gas storage.

While maximum temperature limits, overall weight of the container, and container color are important aspects related to CNG containers, they are not mandatory information that must appear on the nameplate, which is focused on safety and compliance standards specifically related to structural integrity and pressure ratings.
