Federal Motor Vehicle Safety Standards; Compressed Natural Gas Fuel Containers

Özet

This document responds to petitions for reconsideration of the final rule that established performance requirements for compressed natural gas (CNG) fuel containers. The final rule specified burst test safety factors of up to 3.33 for use in evaluating the strength of carbon fiber containers. In an initial notice responding to the petitions, a single, lower safety factor of 2.25 was adopted, subject to further consideration of that issue. This final rule reaffirms that decision. Today's document also responds to the other issues raised in the petitions.
